ARGH! Not fun. I think the rain puts a little rain drop just inside the port, both sides, and those drops just sit there and mess with your static system. It's a terrible thing to have happen in a plane that loves to whiz bang through altitude. The VSI is an important gage for me in the soup. Bad things happen when it starts sending you through altitudes for the wrong reasons. It was one of my worst times in hard IFR. Anyway, enough rant on that... Answer: I went into my box of R/C stuff and retrieved a fuel line bulkhead fitting. Little plastic bugger. You can buy one from tower hobbies. Part number LXG851 http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXG851&P=7 . I put this tiny bulkhead fitting in my panel, teed off static line behind the panel. On the front side of the panel, where the bulkhead is attached, I have a short piece of r/c fuel line, 1/4 inch long maybe with a plug in it. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXG848&P=7 part number lxg48. When my static ports clog, I just pull the fuel line with the plug stuck in it right off the panel and let the static vent to cabin. Simple Install, quick emergency procedure, and very effective. I spent nothing cause I had this stuff laying around, but you can do it for less than 10$, and have enough stuff for 2 planes. Oh and as a side note, when you pull this plug in flight, WHOAA, does the static and altimeter go bazerko until it settles back down. Takes maybe 10 seconds. The pressure difference between out and in is substantial. Also as another note: For those that don't know, Altrak Alt. hold suppliments in pitch stability reference with static source. With altrak alt hold engaged, I can pull the plug off, vent static to cabin, watch the alt. and VSI go whacky, and the altrak holds steady. A tribute to its realibility on its gryo as primary and static as a backup.

All you've done is transferred the problem elsewhere. First, the problem is with a tired engine, or one that has some seal, valve guide, or ring problem. There is the problem, and fixing the problem is the only sure and safe way. Continued operation only leads to higher oil consumption. Masked by oil separators, recirculators (like you mentioned) you feel 'good' about it. BUT, the solution above will only result in oil in the cowl since the oil will slowly drain down into the airbox (I'm new to RVs and don't know what a FAB really is) after shutdown. Well, that solution would work if you left the engine running all the time!!! But, what happens to the oil you've sucked up into the carb? Well, it's going to carbon up the piston and valve tops and sometime down the road (airway: 8-) ) you'll suffer engine run-on during shutdown. Everything here is speculation, of course, because I don't know anyone that's performed this particular mod to their airplanes .... or at least admitted that they had tried it.

Therefore, I eventually bought a #41 drill to use on holes that were to be dimpled (next size smaller than #40, obviously). Tight fit before dimple, but when dimple, hole is slightly enlarged and rivet fits the way it should.

From: Boyd Braem --> RV-List message posted by: Boyd Braem Jim-- PCV?PVC?--whatever...just get schedule 80 and hook it up... It's my understanding that a PCV valve equalizes crankcase pressure best when there is a variable but still positive pressure differential--this is good for a car going from stoplight to stoplight, but not so good for an opposed-cylinder, flat airplane engine at altitude and at constant rpm. Also, airplane engines are often operated for (long?) periods of time near max output (while a car engine rarely does this), when the pressure differential is almost nil (wide-open throttle). Get a ride in a Ford Thunderbird Super-Coupe (supercharged engine)--if you can still find one--and watch the vacuum--aka, pressure gauge. I wrote a note a while back (actually, copied (stole) it from some one else but I can't remember who)--(should be in the archives) on how to set-up a simple manometer to check crankcase pressure for piston-ring gas blow-by and such.

Mask off the leading edge about 6" back, and drape everything else with plastic .... it's cheap. Cut down the pressure on the gun and shut off the fan (paint fan, not electric fan :-D ) air until you get just a little paint to spray. Spray the leading edges, and get real close .... but keep the gun moving so you don't get runs. Use many real light coats, waiting 15 minutes between coats. If you have to, leave the area and hangar fly with your neighbors or get a drink. Anything to keep from painting too soon. Remember LIGHT coats!!! > I am using Randolph Products, Acrylic >Lacquer, Tennessee Red. > OOOH! Love that Tennessee Red!!! Painted my Pitts with it (Stits)!!! Go to your auto parts place and ask for polishing compound for acrylic lacquer. After the paint is thoroughly cured, use a buffer to polish out the overspray. the closer you get to the leading edge, the more polishing it will take, but with a little practice it will blend into the old stuff. When I paint the leading edges, I make sure to get a couple of extra passes there. Don't forget the spinner (if you're painting it) nose and wheel pants. They all take a beating in the rain and from gravel on the ramp.

An auto engine is shut off with the ignition system, deposits, not just carbon, on the piston tops can cause engine run-on. When you kill the engine with the mixture like in an airplane, your engine will not run-on unless it is blowing buy and burning enough oil to sustain combustion. If an engine had that much blow by it would have to be REALLY sick! Plus, most of the "deposits" on the piston top come from the ash (metallic additives) in the oil. Aircraft oil is ashless. I don't buy the acid thing either, there is a very minimal amount of sulphur in gasoline and that would not significantly increase chemical corrosion in the engine. PVC systems are naturally kind of dirty and maybe the risk a backfire resulting in a fire in the air filter might not be worth the reward. The main reason I can see why PCV (positive crankcase ventilation) would not work in an airplane is we run at wide open throttle too much and there would be no negative manifold pressure to positively ventilate the crankcase. At those high power settings when the blow by was greatest, there would still have to be a breather of some sort. and if your engine was tired, it would still drip on the belly.

Several years ago, on PBS there was a program "Classic Car Shop" on restoring an old Mustang. In the episode of repainting they showed a good trick on how to meld new paint to old. They put a line of tape over the old tape and peeled up the tape where the new spray would be applied. This essentially shadows the new paint so it doesn't form a ridge if you spray obliquely to the raised tape. I tried it using 2" wide green masking tape raising 1" of the edge where the fresh paint will be sprayed at ~ 30 degree angle then applied the paint.--- Damned if I could see any ridge!

Just look at any old Volkswagen. Large tolerances in air-cooled engines are such that some air(and oil) escapes through the ring gaps between the three piston rings no matter how good you build the engine. The oil and air exits into the crankcase where it is thrown overboard under pressure. The separator is a catch-all but does keep the belly clean. My RV4's 0-320 chrome cyllinders still test at 78/80 but burn about 1 qt every 6 hours. The air-oil separator helps. My Lycoming engine book states the allowable oil consumption is 1/2 (.5) pints per hour...... Good Luck.... RR Boyd Braem wrote: --> RV-List message posted by: Boyd Braem Jim-- PCV?PVC?--whatever...just get schedule 80 and hook it up... It's my understanding that a PCV valve equalizes crankcase pressure best when there is a variable but still positive pressure differential--this is good for a car going from stoplight to stoplight, but not so good for an opposed-cylinder, flat airplane engine at altitude and at constant rpm. Also, airplane engines are often operated for (long?) periods of time near max output (while a car engine rarely does this), when the pressure differential is almost nil (wide-open throttle). Get a ride in a Ford Thunderbird Super-Coupe (supercharged engine)--if you can still find one--and watch the vacuum--aka, pressure gauge. I wrote a note a while back (actually, copied (stole) it from some one else but I can't remember who)--(should be in the archives) on how to set-up a simple manometer to check crankcase pressure for piston-ring gas blow-by and such.

How much is a VSI? Probably more than $200. I'd opt for the static option in the pitot. Or, you can save the money now, and then roll the dice. Personally, I would roll the dice. In a pinch, you could break the glass, but it is not likely that you will ice over both static ports unless you really plan on flying some hard IFR, in my opinion. Don't want to start a debate on IFR flight, but I think too much redunancy is overkill. We train for things to fail, so deal with what you have, and maintain an adequate balance of how much redunancy you really need. Bob Knuckolls book describes this in detail with his electrical system. Design it right, build it right, and put in minimal backup, and you shouldn't have Murphy come visit you.

It is normal to be apprehensive about the first flight. Two years after my first flight I still get butterflys thinking about it. If you are not apprehensive about the first flight then you really should not make it. 2. I built my airplane and for 100% of it's flight hours, I have been the PIC. This airplane of mine is an extension of me, I made it, it was my sweat and tears that put it together. I was not going to let someone else do the honors of the first flight. 3. I have found the RV6 much easier to land and takeoff than a Citabria, if you need more TD training, find a Citabria. Or go to Arizona and have Budd Davidson teach you how to land a Pitts, if you can handle a Pitts then you will have no problem with an RV. 4. Regardless of who makes the first airplane flight, you must still make your first flight. All of the previous poster's precautions still apply. Just because Chuck Yeager flew it, that does not mean you can. 5. There comes a day when you just need to open the throttle and go for it. Remember a little fear is good. If you can consistently wheel land a Citabria without a bounce, then you can land an RV. After a 8 hour check out with Mike Seger, It took me another 50 hours in the Citabria and just before my first flight an additional 3 hours in a Luscombe before I felt ready (all of this time was in the traffic pattern shooting touch and goes and some fullstops). I had a little over 200 hours total PIC when I did my first flight. 6. Astronauts are so good because, in my opinion, they are so over trained. Get more training, then get some more, ( and I don't mean more from Mike Seger), when you feel overtrained, then go for it. My first flight was anticlimatic, sort of a real let down, nothing went wrong! That is good. 7. In the end, only you can weigh the risks versus the rewards. Use good judgement rather than emotion in making the decision. Either decision will be forever.

They have a very free wheeling discussion list that airs comments, questions and complaints from customers and non-customers alike. Several company employees participate but as far as I can tell, they do it under their own names. Most of the posts seem to be about ideas for future developments or resolving installation questions. Most of the complaints have had to do with delivery schedules rather than performance of the equipment. It would appear that many of their customers are enthusiastic about what they have received, and especially about the constant upgrading going on at Blue Mountain, based largely on customer suggestions. Their discussion list is wide open to anyone. You don't have to subscribe or identify yourself to either read or post messages. I do have a vested interest here. I have put up a lot of money in a bet that what they are delivering is worth the money. The EFIS/one I am currently installing in my still under construction RV-8A has performed on the ground exactly as predicted by Blue Mountain. It was delivered as promised for the price they committed to over a year ago. It had been upgraded significantly since my order was placed. I had the option of not going along with one hardware addition that was recommended at an additional cost. I chose to go along with it. My dealings with them have always been handled to my satisfaction. One thing I do want to emphasize here is that in this really fascinating free-for-all new industry developing EFIS for experimental airplanes, there seems to be a whole lot of half truths being thrown around. In the long run we will all benefit as the laws of physics and the market sort it out. I am very comfortable with where I have put my money, but as is obvious, I am frustrated by the self-appointed authorities who seem motivated by something other than a search for the truth. As for Sam's history with Blue Mountain, it's all there on their discussion list for anyone to see. It certainly appears to me that they have treated him with more fairness and generosity than he has them. As for "honorable business practices", I am unaware of anything other than companies bashing each other's products or technology which I do find less than honorable. I think any accusation of more than that needs to be backed up by something or it becomes a close kin what it is claming another to be guilty of. If you are holding Blue Mountain responsible for what an anonymous person posted on their discussion list (and I quoted to this list) and you are doing it because Sam said it was from them, then I think you are making a mistake. Just to be very clear here, I don't want to imply any criticism of Dynon or GRT or any other manufacturer here. Even the accounts of bashing each other's products are almost always 3rd hand. When you talk to the principles involved, you will almost always find courtesy and respect for their perceived competitors. I especially don't want to offend those who have chosen Dynon. I know a little bit about Dynon. I think it's a great company with a great product. I like the way they do business. I do not see them and Blue Mountain as head to head competitors. Their products overlap, but they are not the same, at least not yet. My BMA EFIS/one is a virtual glass cockpit. It includes the AHRS, but it also includes the air data (so does Dynon) plus a GPS based moving map display instantly switchable from two VFR modes to IFR high altitude and IFR low altitude. It has a real synthetic vision display, showing the GPS derived terrain on the horizon of the attitude indicator if you select that mode. This terrain shows in red if it is at or above your current elevation, as it does on the VFR moving map display. It uses the GPS and air data information to compute and display wind speed and direction. It has a large, readable H.S.I. which can be digitally interfaced with an Apollo SL30 nav/com and some other radios to set com frequencies, VOR, ILS, ILS back course, Localizer, Virtual VOR (VOR derived from GPS data) and glide slope. It displays all the engine gauges that you choose with the limits and ranges you set and alerts you to over or under limit or defective readings even when you do not have the engine gauges displayed. It has an optional 2 axis autopilot that will fly the flight plan you program with a very logical on-screen waypoint selection process. It will use your set climb and decent speeds, or vertical set climb and decent rates. But way back to what I saw as misinformation that started all this: The AHRS does use GPS information to verify and correct the information it presents, but to criticize it for that as compared to a mechanical gyro is truly unfair. A mechanical gyro precesses and needs to be periodically set level, manually. The AHRS constantly checks itself against GPS information and provides it's own correction. In the event that is loses GPS contact for whatever reason, it still performs like a mechanical gyro. Time will tell who has the right idea and the right product here. If I have misstated anything it is truly unintentional and I'm sure someone will correct me. I have said way too much, but I hate to see what I perceive as a good and honorable company with a truly outstanding product being bashed unfairly.

And why wouldnt I my first flight was three days ago; my computer background screen is a picture from my first flight; I have Vans calendar with Jim Erskines RV-6/7 on the wall; I have the 2003 at-a-glance page from last years calendar next to it with Dan Benuas RV-6A over that; I have my daughters watercolor of an RV-6A right in front of me. Today is a spectacular day in the Pacific Northwest. Cool, but not cold. I look at the weather forecast for this weekend, rain and more rain. Grumble! Grumble! I check the metar: calm winds, no ceiling, 10 miles of visibility. I look outside and all I see is sun. The sirens song gets louder and louder. Finally, I succumb. A quick stop to get gas in the car and it is off to the airport. On the road, while a bit hazy, I can still see mountains more than 50 miles away. I know it will be clearer in the air. Forty-five minutes later, I am opening the hangar. There she sits, MY AIRPLANE! Even without paint and main gear pants & fairings, she is a very beautiful lady to me. I pull N276DM out and start to pre-flight. A friend, Harley Beard, who is building a 6A just happens to drop by and we chat while I finish the pre-flight. My engine start procedure (without a priming system) is not completely figured out yet, but soon the engine is singing its song. Taxi, runup, announce, and then on the runway. Stick neutral, add power, lift the nose just off the runway, hold it there, and then we are flying! Climb up to 5000 (Arlington is about 140) to enhance my gliding range. Level off and power back to 2400 rpm. Today is a break in the engine day. Up here, I can see a huge hunk of the Puget Sound and freshly snowed on mountains almost every which way I look! I fly north up to Skagit airport circling it at 5000. I do some turns around the hills and check out a small antenna farm. While always a little nervous, after all, its a new (rebuilt) engine and airplane, I am content to float up here and look down on my surroundings. I check out the Dynon EFIS-D10: attitude looks great, airspeed within a couple of miles per hours compared to my ASI, altitude within 20-30 feet. Even in the bright sunlight with sunglasses, I can easily see the display. All too soon, I head back to Arlington. Going down hill to pattern altitude, I see 180 mph on the airspeed. There is only one other plane in the pattern so I easily enter the downwind. Downwind checks, now abeam the numbers, power back, hold the nose up to bleed off airspeed. First notch of manual flaps, turn base, second notch of flaps (Hmm, maybe I should put electric flaps in this thing!), and then the turn to final. Stabilized at 85, keep the number in the windshield like Mike Seager taught me. Close to the ground, so level off. Much better today, one of my biggest problems is leveling off too high above the runway. Now flare, more flare, more flare, touchdown! Keep the nose off the ground until the plane refuses to hold it up any longer. Cool, I could have made the first turnoff easily, but I coast on by since I need gas which is farther down the runway anyway. Off the runway and taxi to the pumps. Shutdown. A moment for reflection: this collection of metal, wire, fiberglass, etc. really is an airplane. 12 years and 2500 hours have resulted in me being able to fulfill my dream of flight, a dream I have had ever since I can remember. My first fill up: 29.14 gallons, $74.63. Yikes! Thats a bunch of money! But is it? Lets see, 29 gallons are about 3-1/2 hours of flight. How much does it cost to go to a college or professional sporting event? How about a concert? Yes, it is expensive, but those 3-1/2 hours of flight will give me more pleasure and satisfaction than a lot of other activities. Yes, I know there are other costs involved, but Im satisfied with my choice of leisure activity. Finally, its back to the hanger, clean the windscreen, and the drive back to work. Guess what I was thinking about during those 45 minutes! Doug Medema RV-6A N276DM PS I promise not to file a flight report for every flight, maybe every second or third! Just kidding! ________________________________ Message 32 ____________________________________ Time: 03:51:23 PM PST US From: "Paul Stratman" Subject: RV-List: Compare a Dynon to the Blue Mountain --> RV-List message posted by: "Paul Stratman" I was reading on the Blue mountain site how crappy the Dynon is. This statement came from Greg right after he stated as "never having flown the Dynon". BROTHER! Anyway, I kept reading Greg's post and saw this: For grins, try this with one of the cheapies: 1. Fly a series of bank to back Chandelles and recover on the instrument. Watch it closely -- a nasty trick is to re-erect the solution as soon as the plane isn't accelerating. Makes a pretty demo, but a dangerous instrument. 2. Turn 360 degrees in a 2 degree bank, then 4 degrees, then 6 then 8 then 10 then 20, 30, 45, and finally into 60 degrees banked turn. Having done 9 orbits, recover on the instrument. This classic VFR into IMC spiral has a known effect on this class of instrument and is worth seeing, if you intend to use one. Well GREG, guess what? I have done this with the Dynon and it passes the test with flying colors. I have been flying with the Dynon now for 125 hrs and simply can not believe how nice a piece of equipment this is for the $ 1995.00 price tag. Way to go Dynon!

Good grief.......I sure wish I didn't have to stink up the list with another post to this thread but my integrity and honesty has been challenged. Please delete NOW if you don't want to read this response. I did not make assurances that the "anonymous" post came from Blue Mtn. Avionics. My statement about BMA's "aggressive marketing" was in response to the other posts on the BMA forum that day, posts that Terry didn't realize I had read. BMA's position on the Dynon has already been challenged by at least one other poster in this thread on this list. My dog is not in this hunt; I have committed to the Dynon so at this point it doesn't matter to me which is the superior system. I did find Greg Richter's assessment of the Dynon to be interesting when he stated yesterday: " I figure since the Dynon isn't sold as a flight instrument no one would buy it except for panel dressing." Even though I think this is a foolish thing for a manufacturer to say about another manufacturer from a public relations standpoint, I certainly defend Greg's right to make such a statement. but as is obvious, I am > frustrated by the self-appointed authorities who seem motivated by something > other than a search for the truth.

With as much beta testing as I have done for various RV-related efforts, and with a huge volume of posts to this list and others over the past five years, and after laying bare the construction of my RV-6 to the critique of thousands of readers on my web site, my credibility as one who is interested in finding the "truth" is not in doubt. I am confident that since Terry was referring to someone other than me when he referenced "self-appointed authorities", I will leave it to those "authorities" to defend themselves. As for the detailing of my history with BMA.......Terry, the posts on the BMA forum don't tell half the story! I have been very careful to be fair and honest with those posts and the posts I have made on this list. Here is an excerpt from the latest message to me from Greg Richter regarding what I had written about my efforts to fly an EFIS/lite: " Sam, I've read your stuff and haven't gotten on your case about it since it's factual. I agree we have a cordial relationship and that we never did get your Lite to go. It was one of the first ones we made, and I think we had a magnetics issue either in the hardware or way we hung the thing in the plane, although I'm not sure since I never flew it. At that time we were playing with a magnetic slaving technique that was still in it's infancy -- it never worked out for the Lite, although we do use a variation of it in the EFIS/One for another purpose. Short version is you said "Don't Work" and I agree, it didn't work for you when you tried it." Terry, does that sound like it came from someone who thought I had been unfair and dishonest with his company? Since that message I have written very little about the BMA products, and the post of a couple days ago that seemed to raise your ire was not a dig at BMA, but simply an illustration in the discussion of solid-state gyro performance in the absence of GPS data. I sincerely hope this will put this issue to bed once and for all. These are exciting times in our world of experimental aviation, and we will all benefit from the revolutionary work being done in the avionics community. I wish the best to all the players involved.

I am not an engineer and only have the following to offer. Like Mark, I to contemplated some form of application of an automotive PCV valve. Some general history: Before PVC, (i.e.) Positive Crankcase Ventilation, combustion engine crankcases were Passively Ventilated. The blow-by and all it's accompanying gunk was dumped to the open atmosphere. A simple baffle oil separator and pipe served to vent the crankcase. For a partially active system often the outlet end of the pipe was deliberately positioned to take advantage of airflow to assist in drawing the nastiness out. Engines that suffered blockage of the venting system or loss of the pipe faced from somewhat to seriously shortened life cycles due to pressure buildup in the crankcase. When the pollution that resulted from the "PV" system became generally recognized as a bad thing the PCV was introduced. The induction system (carburetor or fuel injection) was recalibrated to allow a variable flow limiting device with a preset maximum rate to continuously sample (leak) the crankcase gases into the intake manifold. The PCV unit was mechanically calibrated to flow a maximum amount with margins for normal wear that matched the cubic inch displacement of the engine. Commonly the valve was plugged into a rocker valve or at some point higher up gravity wise on the engine to aid in oil separation. Again a simple baffle separator included at this point, was part of the system. The flow of offending gases were then brought to a fitting on the intake manifold. Crankcase blow-by gas flow was then regulated by intake manifold vacuum (automotive speak) or manifold air pressure (aircraft speak). In the case of low or idle throttle position (lowest manifold vacuum pressure) the valve's mechanical internal maximum flow calibration came into play. In the case of full throttle position the air pressure in the induction manifold is equalized with the ambient outside air. In this case any extra blow-by gases will in effect be above ambient air pressure and therefore flow to air flow path into the induction system. Through re-thinking pollution considerations and some slight engine design changes internal combustion engines became one more step complicated, environmentally acceptable and able to utilize a small portion of previously wasted gases. Weather or not the "previously wasted gases" being introduced into the intake manifold provide benefit out weighed by mechanical negatives or not has been argued ever since. The PCV has however become standard procedure Failure modes: Along with the added complexity comes our friend Murphy. Few people driving cars have had knowledge of failures of their PCV system. Most those that do encounter PCV system failures just think their engine was old and died of natural causes, hand over the keys to The mechanic, the wrecking yard, or what have you? When engine wear and old age conspire to overload the PCV calibration margins the only recourse is to accept the inevitable and spend some money. The PCV system is quite robust and seldom fails. When it does it is most often the valve itself that gets overloaded with crud. Hoses weathering or blockages in them and their fitting etc. are also culprits I looked into the possibility of installing a PCV on my O-360. I soon realized that I was not prepared to re-calibrate the induction system. Also as the majority of the induction system is housed in the (oil pan) crankcase area it would be very difficult locate a good location for the PVC gases to enter the induction system. A hole drilled at the carburetor base is not for me and I don't care to abide the added failure modes that would be required. Mark, I doubt that installing the breather hose to the FAB will work as you intend, In flight this box is actually under varying degrees of positive air pressure related to airspeed, not vacuum. What you propose could in fact pressurize the crankcase. I am not suggesting that it can not be done The above is not guaranteed to be 100% accurate. I would appreciate any and all corrections and additional information. I hope it is of some use to the list, Jim in Kelowna ________________________________ Message 41 ____________________________________ Time: 05:24:21 PM PST US From: "Larry Bowen" Subject: RE: RV-List: clinched rivets? --> RV-List message posted by: "Larry Bowen" I don't remember seeing reference to #41 on my RV-8 plans.

I gave Greg all the leeway one could possible extend in an effort to allow himself to state the qualities of his product.

This was during the time when they had absolutely no functioning units installed, notice I said "no functioning", not "no installed" units. In talking with the other two companies involved in this thread I can truly say I have never heard either one of them say a single bad word extended towards a competitor. Until Blue Mountain changes their business tactics, it is my personnal opinion (being a CPA I have seen so many companies come and go) they will have a hard time surviving.

I know, I'tll blow up and look like the Airbus at Oshkosh, I'll be able to fry breakfast at SNF on the wings and my shoes will melt climbing aboard but so be it. My canopy frame is now painted black but I'd like some input on the side skirts. Most will think it's anal but here goes. I want to avoid being able to "look through" the canopy and see the inside of the outer canopy skirt and inside canopy skirt. Can you actually see this area when all is said and done? What did everyone else do on the outside of the side and rear canopy skirts, just mask at the canopy and fire away with the HVLP?? Did anyone else paint the inside of the inner and outer canopy skirts before riveting these together and bolting the canopy to the frame and skirts or is it a waste of effort (like I haven't wasted a sh$tload, or is that a boatload, of time already)?

The observation that your squeezed rivets are worse than your driven ones could be blamed on the squeezer. (I'm assuming you are using a hand squeezer.) You have a rivet and sets at one end of an 18" handle pair, and you are at the other end squeezing the handles together. It's hard to keep the squeezer yoke and sets in line AND maintain the right pressure on the rivet head to keep it against the material. This gets worse with 1/8" rivets. The best $350.00 to $400.00 you will EVER spend on your project is a pneumatic squeezer. You can operate it with one hand while you maintain perfect alignment on the rivet. You aren't at arm's length trying to keep that long squeezer lined up. I haven't touched my hand squeezer since I bought the pneumatic one over 2 years ago. Not only does it help ensure better rivets, but you will have a lot more fun dimpling, too!

After some time you will find yourself doing most of the movements in the cockpit without thinking and able to guess your airspeed within 5 knots without looking inside.

You might still be right though...my squeezer is rather heavy and the rivets in question were in awkward spots (also throw in a long 4" yoke), so there's certainly plenty of room for things to come out of square. The ongoing problem, however, is once the first rivet leans over, it squashes the dimple a little in that direction, such that subsequent rivets seem destined to follow in the same direction.

Clark" In response to an email I sent to ***GARMIN AT*** regarding the future of CNX80/MX20/SL70(R)/SL15/SL30 (maybe), I got the following response from ***GARMIN-AT*** ... ============================================================================ ============ James, I expect to see all three systems in question supported for the forseeable future. The CNX80 is currently the only WAAS GPS on the market that is approved under TSO-C146a. It also has a number of other unique features that will secure its place in the avionics marketplace. It has flight planning capabilities that allow you to insert a victor or jet airway into a flight plan with a single entry. It has an infrared dataport that will allow users to do IFR flight planning with greater ease than is now possible. Its display, although smaller than the 530, is equal in resolution. There are other features I could list as well. In the case of the 430 and 530, the success of those products speaks for itself, and they will only get better with time. The GX products will and have been discontinued along with the SL50 and SL60 but the rest of the Apollo products will continue to be produced and supported. The discontinued products will also be supported for years to come. I hope this answers some of your questions, thank you for your email. We value your business and your feedback. ============================================================================ ============ Sooooooo.... according to the "source", GX Series products along with SL50 and SL60 are (or will be) discontinued (though supported). The other products are still being offered. I suspect that they will not make a product with the "UPS" brand anymore, but unless the GarminAT people are outright lying to me (I suspect NOT), then they have products that they are likely to sell as long as there are adequate buyers and there is no conflicting product. The CNX80, SL30/SL40, MX20 and to *some* extent the SL70 (R) are in fact unique products. I cannot see them continuing with the SL15 for too long but since that is basically a PSE unit, you are still "good to go" there. I am looking at using some combination of the above.

I can't see spending 3-9K on an exterior paint job then paint the interior with $70 bucks worth of gray. So why not give our pride and joy the color it deserves. LOL..

Most 4" thin nose yokes are only rated for a 3/32" rivet although you typically won't see that noted anywhere. Even most standard 4" yokes are only rated for a 1/8" rivet & will flex substantially on the longer rivets. You need to call whomever you got the yoke from first & ask what size rivet it's rated for before trying anything else. With respect to the 2nd part of your message - a pneumatic squeezer is a very friendly tool, but it's also very dumb! Once it starts to squeeze a rivet crookedly (at an angle) there's absolutely no way to straighten it out. Drill it out & put in another one. Continuing to squeeze a rivet with 3000 lbs. of pressure, at an angle, in thin aluminum will undoubtedly deform not only the rivet, but also the surrounding skin as you have discovered. If you want to final size the prepunched holes to a perfectly round, exact size use #30 & #40 reamers instead of drill bits. Also remember that the pilots on the dimple dies are sized #30 & #40. Not disrespecting any one else's experience &/or practices, but those pilots are designed to fit specific hole sizes so the rest of the dimple die can form the material around it. They are not designed to do additional streching &/or forming although they will if used in such a manner. When using the pneumatic squeezer we suggest you put the cupped squeezer set in the top of the yoke & "hang" it on the manufactured head of the rivet. Much easier than trying to come onto the manufactured head straight with the cupped set in the set holder while trying to balance the tool, especially in tight or awkward places. Using the smallest yoke appropriate for the job will also help you balance the tool. We contribute articles monthly to the SoCal RV NewsLetter. The newsletters can be found at: http://www.rvproject.com/SoCalNewsletters/ You might want to check out the articles in the July & August newsletters. They specifically deal with Tolerances & Pneumatic Squeezers which you are addressing at this time. Any other questions, pls. contact us off-list. Blue Skies! Fred W.
