    Subject: velcro peeling off
    From: "Frazier, Vincent A" <VFrazier@usi.edu>
    --> RV-List message posted by: "Frazier, Vincent A" <VFrazier@usi.edu> SNIP I tried gluing a half strip of velcro to the metal seat back and seat base, with the other half sewn into the fabric cusion. Problem is, I've yet to find a glue that's stronger then the velcro. Any time I need to remove the cusion, the glued velcro strip comes along with it. I suppose I could rivet the velcro strip to the seat back. Any other ideas? Andy SNIP Yes, there is a better way. Put a narrow strip on the seat cushion, say 1" wide, sewn on of course. Then put a wider width, say 2" or wider if you can find it, on the seat back. The wider strip will resist pulling loose much better. If you can't do that, simply put the strip on the seat back PERPENDICULAR to the strip on the cushion. And don't use cheap velcro! You can get heavy duty stuff in various widths at Walmart in the fabric dep't. Not just a hat rack.... Vince

    Subject: Painting problems
    --> RV-List message posted by: "Tom Gesele" <tgesele@hotmail.com> Listers, I've run into a little problem while painting my canopy frame. The paint ended up real soft, to the point where anything that rubs up against it takes the paint off down to the bare metal. I used Imron over veri-prime and let the paint set up a full week before I even touched it. Does anyone out there have any ideas on what may have caused this and/or can suggest a possible fix (other than stripping the whole thing down and starting over again) Thanks in advance for any advice.

    Subject: Painting Web site, forums, educational data and professional
    supplies --> RV-List message posted by: P M Condon <pcondon@mitre.org> Long post www.autobodystore.com A great site to learn (or relearn) painting basics and purchase professional supplies. I purchased my Devilbiss Plus Gravity gun from them at 150$ off list. The paint gun was selected based on conversations with Len Stewart, owner/operator of the online shop. Len will answer questions and generally help you with your paint needs. I found the counter folks at the jobber stores less then helpfull, lacking in product familarity and generally lacking in the painting knowledge in general. I only buy the paint from them now and rely on the data I got from the forums. Here is the section on "Painting Basics" from Len's web site...... Being HVLP and low VOC products are the way the industrys going I will be referring to them in this discussion on painting and paint guns. Most all basic issues dealing with HVLP can be applied to conventional guns, atomization is atomization. The HVLP just arrives at it differently. The object of the spray gun is to break up the primer/sealer/paint/clear (I will call this PSPC from here out) into small particles and lay them in neat little rows on the panel being PSPRed. So the whole outcome rests on how well the gun is doing this. Picture the droplets of PSPC coming out of the fluid tip of the gun and then the air slapping them into smaller droplets. You have two things that help you with this process, air and solvent. Solvent can mean something that is already in the PSPR from the manufacture or something the manufacture has told you to add to it. By the way, you should always mix in proper ratios as instructed in the tech sheet. The thinner (less viscosity) you get the PSPR or the more air you have at the fluid tip of the gun the more it will break up the PSPR. The target for you is getting the perfect balance needed. Too much solvent and the PSPR will have no body, fill, durability, etc. Too much air and you blow the PSPR everywhere but the car, poor adhesion, excessive texture, etc. So, the answer is proper air supply and gun (and fluid tip) choice and how you adjust it. With todays high solids-low VOC (Volatile Organic Compound, you know the bad stuff that goes up into the air we breathe) products there is less solvent. And with HVLP guns there is less air at the cap to break up the PSPC, proper air supply and gun setup is more important than ever. FIRST THINGS FIRST, your compressor and air supply. An HVLP gun requires more VOLUME of air to operate (the V in HVLP, High Volume Low Pressure). Now you may notice that your HVLP gun is adjusted at maybe the same PSI as an old conventional gun, around 50 lbs at the gun (many HVLP guns are set at much lower though) so where is the Low in PSI they are talking about? It is at the actual air cap where the air and paint come out. An HVLP gun has only 10 lbs at the cap while a conventional has upwards of 50! So the VOLUME of air (CFM, Cubic Feet per Minute) is the key to proper atomization with an HVLP. If you have a gun that requires 15 CFM you will need a compressor and plumbing that will produce that at a very minimum. There are HVLP guns that need as little as 7.5 CFM so you can get good results even from a smaller compressor. Air supply is a complete subject by its self so lets assume that you have the air supply needed and move on to gun set up. So atomization is the key, but why? Why cant you just lay it out wet and let it flow, as an old painter will say. Picture a jar full of bbs, they will represent well small, atomized droplets of PSPC. The gaps in between the bbs is solvent. Now picture a jar filled with marbles, they will represent large, poorly atomized droplets of PSPC. The gaps in between are, you guessed it, solvent. If you apply your PSPC in large poorly atomized droplets, what you will have is a film full of solvent. This can and will cause slow curing, shrinkage and dieback (the loss of gloss in the hours and days after application). So, now that we have learned the need for gun set up, how do we do it? Lets start with the fluid tip choice. The newer high solids low VOC PSPC products need to be broken up more, so a smaller fluid tip is needed. Basically you want the smallest fluid tip that will still allow you to PSPC the particular part you are PSPCing keeping the entire thing wet and in a fair amount of time. In other words a 1.0 tip would be beautiful for clearing one fender, but would be lousy to paint a complete. The application would be way to slow and the first panel would be way to flashed by the time you got around back to it. So you need to compromise, a 1.3 is a great all around tip, while a 1.5 though getting a little big, can get you by. If you read the tech sheet on the particular product you are shooting, it will have a recommendation for fluid tip size. There are needs for other tips, for instance when shooting polyester primer you may need as big as a 2.3, but for urethanes and epoxies, the 1.3 or 1.4 will work great. If you plan on using a pressure pot or paint a bus, all bets are off and we would need to study a little bit more. As an example of the use of a 1.3 tip I did a test once that proved the point well. I shot two panels of metal with a med solids urethane primer. One was shot with a 1.3 super high atomizing top of the line topcoat gun. The other was shot with a 1.5 (or a 1.7 I cant remember) hoser primer gun. Three coats were applied and after a full cure (the one shot with the larger gun took MUCH longer to flash and cure by the way) the film thickness was measured. The one shot with the 1.3 tip was 2 tenths of a MIL thicker! The larger gun laid out the marble sized droplets full of solvent and when the solvent flashed the film shrank. Air supply is a subject that could fill many pages by its self. So we are going to assume you have that covered and move on to gun set up. You need to tune your gun EVERY TIME you use it just as you would tune a guitar before you perform. This is done with a very basic spray out pattern test. This very basic test tells you how your gun is atomizing and you adjust it to achieve the best atomization you can. Lets do a spray pattern test: Set the fan width as need (you dont want to change it after you have tuned the gun). Turn out the material knob about 2 turns. This is the mixture adjustment, kind of like the idle screw on a carburetor. The farther in it is screwed the lower the fluid to air ratio is and the smaller the droplets will be. The farther out it is, the higher the fluid to air ratio is and the larger the droplets. Set the air pressure at the inlet to the gun to the manufactures specs. On an HVLP gun this spec is usually found on the gun and is the maximum PSI it can have while still maintaining the maximum 10 lb at the cap for legal HVLP transfer efficiency (68 %). You are now ready to do a test spray out. Tape a piece of masking paper on the wall for the test. Hold the gun at a right angle to the wall, just as if you were going the wall. Hold the gun at a spread out hands distance (about 8 or 22cm). Pull the trigger to completely open for a split second and then close it. You want an ON-OFF wide open-completely closed in ONE movement. You should have a cigar shaped pattern with complete coverage in the center with fading coverage going away from the full coverage cigar shape in the center. The center should be fully covered without any runs. If you have runs, either you are holding the trigger too long, you are too close or the gun is simply applying too much material. In which case you need to screw in the material knob or turn the air pressure down. But most likely if you have turned the material knob out the 2 turns and the air is set at the factory specs, you are just too close or holding the trigger open too long. The droplets you see trailing off the center are what you will use to tune your gun. Turn in the material knob to make the droplets smaller (and or raise the air pressure). The balance you need to attain is the smallest droplet size possible before you loose the coverage desired. In other words if you turn in the material knob too far, not enough material will be coming out to cover the panel! Now, youll notice that I said, raise the pressure to the gun, while earlier I said to set it to manufactures specs. We are talking a very small adjustment. It is a fine balance in material to air ratio and a little more air than specified is okay. Even if it is an HVLP gun the inlet pressure recommended is to maintain the 10 lb limit at the cap. Well, about three quarters of the country has no regulations for HVLP use so if you go over the 10 lbs all it will do is atomize the material a little better. You may loose a little of the benefits of HVLP though. But remember you have a lot of control with the material adjustment knob. After you are happy with the droplet size, DONT TOUCH THE FAN CONTROL. It will change the PSI at the cap and will change the atomization you worked hard to get. Do this spray out every time you spray as material change, temp, and humidity will necessitate a spray out droplet pattern test. Good luck!

    Subject: Bad wing rib to spar rivets
    --> RV-List message posted by: "GEORGE INMAN" <ghinman@attcanada.ca> I have been happy with most of my rivets until now. During the riveting of the wing ribs to the main wing spar I badly deformed some of the factory rivet heads. See them at http://www.ahyup.com/Rivet/ To make the rivets I used a 2X gun at about 60 psi. It would take 3 to 4 seconds to make the shop head to my satisfaction. I was paying much to much attention to the shop head and ignoring the factory head. I also made some smileys in the ribs. What should I do to make this better?

By the looks of some of your rivets you may have used the wrong size rivet set (too small) GEORGE H. INMAN ghinman@attcanada.ca

This was the right wing too, I had already done the left wing and for some (luck of the draw, I guess) reason they all turned out OK. Anyway, I ended up drilling out over 18 rivets!

    Subject: Re: seats fabrics..
    --> RV-List message posted by: Bob <panamared2@brier.net> A comment on seat fabrics. I don't know how everyone else gets into an RV6, but I end up stepping right in the middle of the seat before I am able to lower myself into the seat itself. After a time this makes the fabric dirty/dingy. Depending on how you enter and exit the aircraft, you might consider this on the color and type of seat covering you use. I have tired to find a good heavy canvass, OD in color. Neat thing about OD, the dirtier it gets the better it looks. When I ordered my seats from D.J. she laughed at me and told me canvass was not an approved covering as it was not very flame proof. Somebody should have told all those Guys with the Right Stuff at Edwards AFB during the 60's, as I recall the XF107 had a canvass seat laced to a tubular frame! So I have very nice dirty seats that are flame retardant. Bob RV6 NightFighter

    Subject: Re: RV frame of mind
    --> RV-List message posted by: WMPALM@aol.com Geoff, After working several years part-time on a Velocity kit, I sold the kit about 50% complete and bought an RV-8A QB kit. It was a very good decision for many reasons. The main reason, though, was that I simply could not build the Velocity with my work schedule. What I learned is that fiberglass kits must generally be built in 8-to-12-hour increments due to lay-up and cure/monitoring time. If you're retired and can work full-time on your kit, this is probably okay. If not, I would recommend sticking with an aluminum or steel and fabric kit. You can work on aluminum a few hours every day or evening and then quit. If you quit early on a fiberglass layup, you could have a nasty surprise when you check it later! I know! A little story: Ten years ago, when I first approached my wife about building an airplane, I told her that I would like to build an RV-6A. She said, "How many seats does it have?" I said, "2." She said, "Wrong Answer." (We had 2 children still at home.) Now that the kids are on their own, we're happily building an RV-8A! If you need 4 seats, build an RV-10! One other note: If you look at RVs from a performance, safety, builder support, and almost any other objective measure, they almost always beat the heck out of a Cozy or a Velocity. My personal opinion is that you've really got to like the "spaceship" looks of the pushers to justify building them. Good Luck with Your Decision! Bill Palmer

Geoff Bowman, North Carolina Geoff, I've built a plastic airplane before I saw the light and switched over to the dark side. I have one thing to say...................Can you say, "epoxy rash"?? Seriously, I'll not get into the differences in the two airplanes but I will get into one issue than presented itself dramatically when I started on my RV. When you rivet A & B together to make AB, you can rivet C onto it to make ABC. On a plastic airplane you must epoxy A & B together and wait two days to glue on C. It has been a much more satisfying building process with my RV than it ever was when I lived in the plastic world. Another thing with plastic is take a picture of it when it is completed, it will never look the same after the heat and UV start distorting all those nice close joints between various parts. Switch to the dark side. The only things you have to deal with are not drilling your fingers (haven't done that yet where it brought blood ) and those nasty alum pubes.

I know Van would not just throw darts to determine GW, but what I am sure he has done is built in a fudge factor for those who push the limits, just to keep it from falling out of the sky. If he recommended the weight at 1800, someone would go 1900, and so on. I have heard many mention that this airplane is over engineered in many ways for this reason exactly. Van's has told me not to worry about certain things due to the fact that the plane is over engineered to allow for let's say, poor building habits. I think most airplanes are this way. They can't set all the limts at the *real* limits, or we would have alot more accidents due to accidental (or intentional) acts of exceeding limits.

    Subject: governor hose hole in front baffle
    --> RV-List message posted by: "Dan Checkoway" <dan@rvproject.com> On my RV-7/IO-360-A1B6, the governor hose OD is 1" including the firesleeve. I'm curious what the best way to protect this hose is, as it passes down through the front baffle floor. Grommet? RTV? The reason I'm even asking about this, rather than just simply using a grommet, is that the location of the hole kind of straddles the edge of the baffle bracket (part #16 in my kit) and the .063" doubler. The issue is that the grommet would have to accommodate varying thickness...in some areas baffle+doubler+bracket, baffle+doubler, and just baffle. The range is basically .032 to .125, so I'm not sure if a grommet is best suited for this. Here's a photo of the front baffle, showing the location of the hole-to-be...the clecoed hole is a good centering candidate: http://rvproject.com/images/2003/20030928_hose_hole_to_be.jpg And here's a photo up from underneath, showing roughly how the hole will straddle the edges of various thicknesses: http://rvproject.com/images/2003/20030928_hose_hole_beneath.jpg If I were to drill the hole exactly 1", I believe the firesleeved hose would have a snug fit. But I can't imagine that letting the firesleeve chafe against the hole would be kosher. What's the best way to protect the hose in this case? Thanks in advance, )_( Dan RV-7 N714D http://www.rvproject.com

After a time this makes the fabric dirty/dingy. I think it depends partly on whether you've got electric or manual aileron trim. Those with electric can use that area between the seats, just aft of the spar, to step on -- avoiding the seat-shoe contact issue. If you've got manual trim, the knob precludes using the area as a step. do not archive )_( Dan RV-7 N714D http://www.rvproject.com

Geoff Bowman, North Carolina --- Geoff, I've followed both the EZ lists and the RV lists for about 5 years in anticipation of the time I would build and initially had the same thoughts. It's been a long time since I convinced myself the RV is just more 'bang for the buck," and that doesn't count all around performance advantages of the RVs. Below is a clip from a builder of one of the EZ/Cozys: ---cut here--- Has anyone flown their Cozy into the Taos Regional airport? Did you have sufficient runway to comfortably fly in and out? What time of the year did you visit Taos? http://www.airnav.com/airport/SKX Runway length is 5798' and the elevation is 7065' MSL ---cut here--- Don't recall ever seeing such a message from an RV builder. If you intend to fly from one looong concrete strip to another, then that sexy looking plane may suit your intended missions as well or better, but I personally want a little more flexibility and may not have the luxury of postponing an unexpected departure from the original flight plan. Speed is within probably about 5% or so anyway. Steve

The former contains grease and the latter is greaseless if memory serves me correctly. Seems that the -1 with grease might hold up longer (i.e. be less likely to wash or evaporate out). Just thought I'd tap into the endless knowledge and wisdom of The Great RV-List to see if anybody has a revelation on which one to use for various applications like rod end bearings, piano hinges, and various FWF linkages and assemblies--and why one is better than the other for said application.

    --> RV-List message posted by: "Pat Hatch" <pat_hatch@msn.com> Like in many, many, other phases of this project, just make sure you're tooling is perpendicular to the work surface...one trick is to try and see the reflection of the tool in the aluminum, and line them up. Especially for drilling and riveting. No need to re-do these dimples, you will have your share of "less than perfect" results, most of them are acceptable, those that don't pass your evolving standards, you can re-do. Learn from your mistakes and move on. At the end of the project, I think you will find that 99% of your workmanship was well within acceptable standards. Many times attempting to improve on a mistake just makes it worse. Bad rivets are the exception, most cleated rivets can be drilled out and repaired, but you have to analyze what went wrong with a cleated rivet so that you won't repeat the error.

    Subject: Re: W&B on a -6A
    --> RV-List message posted by: dmedema@att.net A couple of comments based on the recent posts regarding my gross weight of 1800 lbs. I decided on 1800 lbs based on various messages posted on the RV list over the years. A major one was with regards to the float conversion which supposedly received an ok from Van to go up to 1800 lbs. There have also been postings giving G loads at various weights and 1800 seems to still be in the Utility category. I haven't had my plane inspected yet (still waiting for the Feds), but am confident that I am allowed to set the gross weight to what I want since I'm the manufacturer. A slightly related issue is that there are no structural differences between the -6 and the -6A, but the gross weight was raised by Van by 50 pounds. I wonder what the ultimate gross weight really is for these planes and how is it determined? I suspect gear loads on a rough landing have a lot to do with it. With regards to insurance issues: I'm certainly no legal expert, but I would rather be at 1700 lbs with a listed gross weight of 1800 rather than a listed gros weight of 1650.

But my real advice to any new builder is that you ought to take the SportAir "RV Assembly" workshop. It's *well* worth the money. http://www.sportair.com/workshops/RV%20Assembly.html Alternatively/additionally, find another local RV builder and/or an EAA technical counselor. Other builders are what really make this whole thing happen. I definitely would not have gotten this far without other guys locally and all the help I've gotten on the email lists.

    Subject: Re: [new builder] Dimpling..
    --> RV-List message posted by: "Jim Jewell" <jjewell@telus.net> Hi Radomir, Give some thought to stopping now and making a table top addition that will hold the work pieces level with the dimple tool. I built a removable table / bench top about 36 inch wide and 6 or 7 foot long add on that had a slot in it for the C-frame tool. My dimple C-frame is out on loan so I cannot give you a depth measurement. This table top unit is the same depth as the height of the dimple tool and will be suitable for all the various panels that will need to be dimpled. With care doing dimples this way will ensure correctly formed dimples and eliminate distortions that can and do result from dimpling with the work pieces loosely held or draped over the dimpling tool. When not in use I stand the table top out of the way against the wall. Also try dimpling some scrap materials of different thicknesses. a properly formed dimple. When held up to a light source with a straight edge across the top of the dimple there should not be any space between the outer edge of the dimple and the straight edge. You might be surprised at how hard the dimple tool needs to be hit to get a good dimple on an otherwise flat surface. If you plan ahead and build the table height to accommodate covering the top of the dimple table with cloth, carpet or what have you, you will reduce the scratches that can come from sliding the work piece back and forth while dimpling.

Well, that's not exactly true. The main gearlegs on a -6A mount to the front of the spar, don't they? And the nosewheel into the engine mount. I think the default configuration also used to be a tip-up canopy on a tailwheel, and slider on a nosewheel, but i'm not sure if that is still the case. I would guess that an RV-6 would also have reinforcements in the tailcone for tailwheel attachment. Off the top of my head, i'd guess that these modifications would suggest that the -6 gross weight shoudl be higher than the -6A, but I didn't design the plane so I don't know what considerations were made. > I wonder what > the ultimate gross weight really is for these planes and > how is it determined? I suspect gear loads on a rough landing > have a lot to do with it. Actually, they don't. Gear loads on a rough landing have a lot to do with how the landing gear is designed, period. What (should) determine the gross weight limitation on an airplane is the aerodynamic structural limits of the aircraft for a given loading condition. In the case of the -6, that's Utility category to 1600#, and Aerobatic to 1400#, if I recall. My -7 will be Utility to 1800#, and Aerobatic to 1600#. I don't know what components are the limiting factors in these conditions, but without analyzing every structural member myself, I wouldn't change the gross weight from what Van suggests. > With regards to insurance issues: I'm certainly no legal > expert, but I would rather be at 1700 lbs with a listed > gross weight of 1800 rather than a listed gros weight of 1650. I have a hard time believing that an insurance company would consider one condition to be better than the other when the manufacturer's recommended gross weight is 1650, unless you have some engineering data to back up your increase to 1800. I doubt your adjuster would accept "well, everyone on the RV-List is doing it and they say it's okay." Just my $0.02. -Rob Prior rv7 "at" b4.ca RV-7 Empennage (still)

    Subject: Re: W&B on a -6A
    --> RV-List message posted by: Dave Bristol <bj034@lafn.org> On my -6, if I had an O-320 and a wood prop, I wouldn't be able to load it above 1600 without exceeding the aft CG limit, since the empty CG starts out pretty will back. As it happens I have an O-360 and a Hartzell CS which moves the empty CG well forward. The airplane is within CG limits when it's sitting empty on the ramp or when it's loaded to 1850 lbs. with 100 of that in the baggage area. So, if Van set the gross weight limit using the small engine and wood prop he probably couldn't have set it any higher and still had anything in the baggage area. So, I think that it might be more of a CG issue than a weight issue. Dave Paul Besing wrote: >--> RV-List message posted by: "Paul Besing" <azpilot@extremezone.com> > >Good question.

This would not be wise to intentionally do at 1800 lbs. I set my gross at 1800, but in my weight and balance sheet I extrapolated the maximum g loading for 1800 lbs to be about 3.6. This was based upon 6 g's at 1375 and 4.4 at 1650. This, of course, assumes that the wing is the limiting structural item. I also never plan to land above 1650 lbs. I recall Van (or someone at Van's) once writing that the landing gear ARE a limiting factor (obviously). It is a probability game, play with knowledge of the risks.

With this loading, I consider the last 50 pounds of fuel (8 gallons, or one hour's worth) to be an emergency reserve, and if it is an emergency situation, I'll take being a little aft of the "allowable" CG over being a glider pilot.

Pure conjecture, but when I started work on my -6A in 1994 there were no sliders designed. I remember it being an option offered in a later RVator. The GW's didn't change for the tip-ups in either configuration, I.e. 50 lbs difference. I expect the raise in GW between -6 and the -6-A of 50 pounds was due to the difference in weights between the tail wheel and the nose wheel with its longer leg + fairing + bigger wheel + fairing and more complex engine mount.

    Subject: Re: [new builder] Dimpling..
    --> RV-List message posted by: "David Carter" <dcarter@datarecall.net> Radomirz, Here's what I learned/did on my RV-6: C-frame dimpler: 1. Build up the area around the C-frame so skin is almost same ht as bottom dimple die - I used some scrap thin, wooden wall paneling and some scrap 2X4 or other stuff that I taped together to get the right height. I laid these pieces on both sides of the C-frame maybe a foot or two away so skin was "generally" flat. 2. I made a strip of wood maybe 3" long by 1" wide and the same thickness as the ht of the dimple die and drilled a hole in the middle and laid it over the dimple die - to give more support to the skin right around the dimple die - big help. 3. Using a wooden hammer (and hearing protection) I go "smack, smack, smack" - the first two smacks bent the metal and the the 3rd smack was like hitting something solid - no more "give" or bending of skin/dimple - the 3rd smack was "final test or proof that the dimple is fully set". 4. Buy the spring that makes the top shaft go back up out of the way so you can move the skin to the next hole. Using a pneumatic squeezer to dimple (you did invest the $200 or so for a pneumatic thing? - Best $200 I ever spent): Set the air pressure all the way up to "Max", i.e, 110, 115 psi or so. REASON: Several of us tested and proved that lower air pressure resulted in the dreaded "not fully formed dimple with an area about the size of a quarter (around the dime sized area of interest of the dimple) that wasn't really flat. Full pressure eliminated that problem. I suppose with a manual "pull the two handles together" squeezer, the same is true - set the thing so it squeezes hard enough to get a nice flat area around the dimple. Oh, and make sure the skin's pilot hole hasn't slipped off of the male dimple die before you "smack" or squeeze!

    Subject: Fuel line help needed!
    --> RV-List message posted by: Bobby Hester <bhester@hopkinsville.net> Vent lines installed, now I move on to the fuel lines and I am stumped :-( I am building a 7A so those gear weldment are there. I ran the fuel line from the flop tube straight back and plan on putting a 90 fitting to attach the tube coming thru the fuselage. I looked at that corner where the gear weldment is and I can not figure out how to even start , Help!!! -- Surfing the Web from Hopkinsville, KY Visit my web site at: http://www.geocities.com/hester-hoptown/RVSite/ RV7A Slowbuild wings-QB Fuse :-)

    Subject: Re: Rv list Hartzell Prop
    --> RV-List message posted by: Dave Bristol <bj034@lafn.org> Hi Joel, Nobody seems to be responding to your question so I'll give it a stab. This is completely from memory so you REAL mechanics out there will need to cut me some slack! On the compact hub propeller they use a combination of a stud and a nut that are pinned together with a roll pin and of course a washer between the nut and the propeller hub. This all came assembled on my prop so I didn't pay a lot of attention to it but I guess they use that combination because there isn't enough room to get a bolt in. The only way you can run the safety wire is through the hole in the roll pin.

    Subject: Re: RV frame of mind
    --> RV-List message posted by: WMPALM@aol.com Geoff, Probably the best way to find a partially-completed kit is by "word-of-mouth" in your local area. Shipping is certainly cheaper, and you can inspect the kit relatively easily. A second option is Trade-A-Plane, but it's likely to be more of a hassle. Note that you'll have to purchase a kit that is less than 50% complete in order to qualify for the repairman certificate. If you're going the RV route and are looking to build as fast as possible, you can't beat Van's Quick Build kits. Good Luck! Bill

Check the archives and the EAA website. The 51% rule should be no problem in getting the repairman's cert on a previously started kit. Just a quick search and I found this one, there are several hundred other examples. http://www.checkoway.com/url/?s=a39d360 Best of luck, Nick == == http://www.matronics.com/trouble-report == ==
