    --> AeroElectric-List message posted by: "Denny Mortensen" <dennymortensen@cableone.net> I get a product from the drug store that is the same alcohol but is 99%. I think it is the type they use for injections. Anyway it has a completely different feel to it, almost dry, and evaporates very quickly and is also cheep to buy. I use it for cleaning tape heads and ext and it works great.

If you get the stuff labeled "91% Isopropyl Alcohol" or higher, you are pretty safe as you are usually getting just alcohol and a little water. So-called 'rubbing alcohol' MAY contain other ingredients ... often oils, and sometimes salts as well (I worked at a pharmaceutical, company in another life <G>) Harley Dixon Denny Mortensen wrote: >--> AeroElectric-List message posted by: "Denny Mortensen" <dennymortensen@cableone.net> > >I get a product from the drug store that is the same alcohol but is 99%. >I think it is the type they use for injections.

    on juliet --> AeroElectric-List message posted by: Ken <klehman@albedo.net> Well I'm not Bob but in the interests of promoting conversation: Among other things it seems to claim that teflon wire is as good or better than tefzel, that breakers and fuses will eventually pop if loaded above 80%, that there are 50 lb of wire in small airplanes and a 28volt system will save 10 lb of wire, he doesn't like two alternators, and 10 awg wire is fine for up to 100 amps of alternator output, and he markets a fancy electronic distribution center... He does give reasons for much of what he says - but I do like to stir the pot and he definately diverges from the common list wisdon here!

    Subject: Touch screen in an aircraft
    --> AeroElectric-List message posted by: "Ken Simmons" <ken@truckstop.com> I don't recall seeing a touch screen in an aircraft or on any of the new systems. It seems with the proliferation of "glass cockpits" that this would follow along. Has this been investigated and discounted for some reason? I believe many of these are capacitive based. Is there too much interference in an aircraft environment that makes them unreliable? Maybe cost? Thanks. Ken DO NOT ARCHIVE

    Subject: Sam James Cowl and Plenum
    --> AeroElectric-List message posted by: "Maureen & Bob Christensen" <mchriste@danvilletelco.net> I'm seriously considering a Sam James Cowl and Plenum . . . I will probably be installing some form of a carbureted 0-360 with either a Hartzell or Whirlwind c/s prop?! For those of you that have done it: Do you believe you gained the 10mph claimed? What if any are the watch-outs for engine and propeller. Would you do it again? Are there any other "speed mods" that provide a good bang for the buck? If I go down this path, I have an extra cowl (Van's, O-360 carb, c/s prop) anybody interested?? Thanks, Bob Christensen RV-8 Builder in SE Iowa

Walk down the isles of Walmart, Target, Cosco, et. als. and how many products offered come with one-on-one education on their use. Of course, there are probably some form of instructions approved by the manufacturer's legal department . . . but if the instructions fall short of being educational, well . . . >The first instance was when you posted this web site page in response to a >voltage regulator question ><http://bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?26X358218>. > >When scrolling through that page I came to the Dynon EFIS D-10 Kit. The >crimper (for machined D sub pins) and the red and white plastic handled >pin insert / extract tool in that kit reminded me that I had recently >purchased similar items and then fumbled for a period of trial and error >while figuring out how they were supposed to work. Yup, many of us learned the same way. Sitting at a workbench at Raytheon, there's usually someone close by who has already been through the learning exercise and can shorten your own learning experience and even offer tips for avoiding hidden hazards. No such assistance resides in your workshop or mine. This is why the AeroElectric-List and similar endeavors are so important. This also illustrates the philosophy behind my consistent advice to everyone who orders new tools and materials for use on their airplane. ORDER EXTRA materials. Don't make the very first pin or connector you install one that goes onto your airplane. >The second instance was when you posted this web site in response to a >question on proper connector pins for MS3471W8-33S (Aero 9903) connectors. ><<http://www.ittcannon.com/media/pdf/catalogs/PV_TBF.pdf>> > >When I went to that site some of my questions were answered, but others >were raised.

Any crimping tool worth it's salt is fitted with a positioner that sets crimp location on the wire grip barrel. The tools B&C sells are the same ones I used to sell. I discovered that the stock positioner is not quite correct. Both the AeroElectric Connection and B&C does some machine work on the supplied positioner to correct this condition. I note that some of the "BIG GUYS" are taking advantage of this particular low-cost tool design. See: http://www.amphenolconnex.com/47009.asp http://www.etool.ca/eTool/RENDER/1/56/500/4053.html I hope they're taking the time to do quality assurance on the tool's functionality. I'm certain that the prices asked by these companies is a whole lot higher than B&C's prices. You may also find them in other catalogs at lower than B&C's prices . . . but that's the hazards of "pulling them of the Walmart peg" . . . >2) How does one assure himself that the pins and tool that he has on hand >are compatible with regard to pin insertion depth? For the most part, the same way that an assembler on Cessna's production line does . . . buy terminals and tools from "qualified" suppliers. These are generally suppliers that have complied with ALL the requirements of industrial, commercial and military specifications. This up-front activity by the specifying and procuring activities relieves the users from having to be concerned about it . . . but they still have to read the instruction manuals. Your first line of defense against ignorance and error is your own education. You can do that here on the list and elsewhere. Next, identify and patronize suppliers who understand and value the symbiotic relationship between good service and the return business from satisfied customers. The price of goods offered seldom drives these relationships. >3) Is there, should there be, any user tool adjustment in regard to depth >of pin insertion? No. Not for production tools. EVERY tool at Raytheon or any other place I've worked, tools have positioners that fix the depth of insertion (locates crimp on wire grip) and adjustable depth of crimp (which is usually set and sealed by QA). See pictures at: http://www.aeroelectric.com/Pictures/Crimp_1.jpg http://www.aeroelectric.com/Pictures/Crimp_2.jpg http://www.aeroelectric.com/Pictures/Crimp_3.jpg http://www.aeroelectric.com/Pictures/Crimp_5.jpg Here's a cross reference list of various tools, positioners matrixed with a huge array of pins. http://www.astrotool.com/Products/turrets_&_positioners_for_mil-c-39029_contacts.htm While net-searching for reference materials, I ran across this company that offers good used tools at attractive prices: http://www.crimptools.com/ >4) Proper wire stripping length is determined by? . . . a need to clean insulation away from the wire grip area. You can usually do this by inspection. It's never more than .12" for small pins and never less than 0.06". As a side note, I don't bother to strip insulation from tiny wires where they'll fit into the wire grip area without stripping. You're more likely to damage the wire by stripping. When you think about it, the gas tight, metal-to-metal crimp happens with such pressure that NO insulation will get in the way . . . insulated extrudes out of the joint as the crimp is made. I've run a variety of tests that showed no difference in crimp strength or electrical integrity whether or not the wire was stripped before crimping a pin to it. >5) What about wire gage, pin, and tool compatibility? A friend has a tool >that wont properly crimp 24 AWG wire in the pins that he has. My tool >properly crimps 26 AWG wire in the pins that I have. Yup, wire grip depth is adjustable on most tools as cited and illustrated above. The low-cost tool I sold was for 22-20 AWG in standard d-sub pins and not adjustable . . . but if you're needing to address a variety of pins and wire gages, get an adjustable tool with interchangeable positioners. >6) What about the crimpers that make eight indentations into the pins >rather than just four? Superior? Essential? Where available? Four is plenty . . . although we're seeing some 12-point grips . . . the tool I cited at: http://www.amphenolconnex.com/47009.asp calls out a 12-point grip feature. If you cross-section a installed pin and look at it under the microscope, there are no open-air voids of a 4-point tool installation. I am mystified as to value of increased complexity for adding more punches to the tool. >7) What is the story on the color bands on the pins? Pure decoration or >are they trying to convey some important information to me? In the far left column of the chart at http://www.astrotool.com/Products/turrets_&_positioners_for_mil-c-39029_contacts.htm you find M39029 series part numbers for pins. The last three digits of the part number are often striped onto the wire grip barrel in the same color code as resistors. D-sub pins are M39029/64-368 and /64-369 so they'll have orn-blu-gry and orn-blu-wht strips on barrel. >8) Is there just one size of pins for all sizes of wire for these commonly >used D sub connectors? Yes, the two part numbers cited above for standard d-sub. >9) What is the largest and smallest size of wire that one should expect to >be able to use in these pins and connectors? 20-22 AWG for the standard d-sub 22-26 AWG for the hi-density d-sub >10) About that red and white insert / tool Are the two ends different? If >so how are they different and how are they to be used? See http://www.aeroelectric.com/Pictures/dse-1.jpg and http://www.aeroelectric.com/Pictures/dse-1a.jpg >11) If I buy, say 9 pin D sub connectors, from one seller to our community >and then later buy some from another seller should I expect the connectors >to be compatible with each other?

    Subject: Re: Touch screen in an aircraft
    --> AeroElectric-List message posted by: "Ken Simmons" <ken@truckstop.com> Those comments are interesting, but I guess I don't see your point. Maybe I wasn't specific enough. I forget sometimes that this list is not just for experimentals. For an experimental, you don't have to spend thousands of dollars on TSO'd equipment. A handheld or portable GPS is perfectly acceptable. Many companies are developing products for experimentals with little or no intent of a TSO. Is there some reason they haven't chosen to use touch screens? This might give them an edge over the competition, assuming it's feasable. I've seen a couple of homebrew EFIS systems that used laptop/computer type LCD displays, but they weren't touch screen. The displays certainly weren't TSO'd.

    Subject: Sticky Labels
    --> AeroElectric-List message posted by: "Bryan Flood" <bryanflood@hotmail.com> Hello all, I am going to use Avery clear sticky backed labels on my instrument panel. I bought the kind that are a full sheet and you print out on your ink jet. Anyway, I was wondering if someone had a template or example of the labels they printed. What I am trying to do is not start from scratch making up all the borders around the text and what not when everyone seems to have all ready done this. It would be so much easier just to change the text. I have looked around on the internet an only come up with one example made in Visio which does me no good considering I don't have Visio( sp?) I have followed Bob's architecture pretty closely so hopefully about 90% of yourtext would work perfectly for me. Thanks, for all the help... Bryan Get ready for school!

    Subject: Sticky Labels
    --> AeroElectric-List message posted by: "Terry Watson" <terry@tcwatson.com> There is software available that formats MS Word for most sheets of Avery labels, and probably others that can be used in Microsoft Word. I'm not sure where mine came from, but here is a source: http://www.worldlabel.com/Pages/software.htm This of course doesn't have all the borders and font sizes that you may want, but it sure makes it easier to create your own labels. Terry --> AeroElectric-List message posted by: "Bryan Flood" <bryanflood@hotmail.com> Hello all, I am going to use Avery clear sticky backed labels on my instrument panel. I bought the kind that are a full sheet and you print out on your ink jet. Anyway, I was wondering if someone had a template or example of the labels they printed. What I am trying to do is not start from scratch making up all the borders around the text and what not when everyone seems to have all ready done this. It would be so much easier just to change the text. I have looked around on the internet an only come up with one example made in Visio which does me no good considering I don't have Visio( sp?) I have followed Bob's architecture pretty closely so hopefully about 90% of yourtext would work perfectly for me.

    Subject: Touch screen in an aircraft
    --> AeroElectric-List message posted by: "Trampas" <tstern@nc.rr.com> When designing my engine monitors I gave this a lot of thought. Touch screens are good for configuring things on the ground, but not good in actually use. Look at the GPS systems for cars and such. As far as buttons go, again look at the cars. Most of the radios in cars are actually going back to knobs for the volume as it is easy to find in the dark while you are driving. I know I gave a radio away because I could not find the volume buttons in the dark with out actually looking at the radio. Thus when I designed my engine monitor I went with a simple knob that you can find blind folded in turbulence.

Pilots immediately found that setting the codes in turbulence was simply impossible. Pilots have lost their front teeth with hand-held microphones. So the next time you fly in turbulence, consider whether or not a touch screen would be a good idea. I think not, but if you could properly stabilize the pilot's hand....maybe. Regards, Eric M.

A future touch screen could be very large with large graphics and icons that feedback with a tone, click or take your pick sound in your headset. Perhaps the graphic would flash brightly as you peck it with your pointy finger. (Didn't they find one large touch screen in the UFO that crashed at area 51?) John P.

    From: "Matt Prather" <mprather@spro.net>
    --> AeroElectric-List message posted by: "Matt Prather" <mprather@spro.net> Along those lines, I think it would be slick if each avionics device was designed to be remotely controlled by something like a wheel/hatswitch arrangement on the throttle and stick. A universal control interface could be devised that each manufacturer would comply with. You want to set the transponder, you roll the thumbwheel on the throttle around until the LED over the transponder was lit, press the active button (also on the stick or throttle) to start adjusting digits using the wheel and the active button. Once the correct code is entered, press the active button one final time, which frees the wheel to select a different device. I definitely like the HOTAS concept. A hatswitch (or something like the rubbery mouse control from a laptop) on the stick would be a nice way to control the cursor position on certain devices (like moving map displays). Who's not used to a mouse (or maybe even trackball) style interface? The thing about stabilizing the hand over a touch screen is that the touch screen is designed to be looked at. As soon as you put your hand up there, it blocks the screen. The act of setting your hand on something to stabilize it seems like it might make seeing the screen difficult. Maybe if you had a nice pad under the screen, your palm could rest against it, and you could rotate your hand up and down to access the screen. Seems like a good way to get carpal tunnel syndrome. From my experience in the semiconductor manufacturing world, machines with touch screen interfaces are easy to learn by the novice, but usually become more cumbersome to operate than mouse/keyboard/dedicated button controlled devices. One thing that I think contributes to this is that tactile qualities of the best touch screens do not come close to the crispness and positiveness of operation of rather cheap knobs and switches. One final thing about touch screens... The displays on the panel which are the easiest to see while your "head is out of the cockpit" are those that are mounted high on the panel. If its mounted high on the panel, it is going to be the hardest to put your hand on and keep it in place while experiencing turbulence. Further, if you mount the display low on the panel, I believe looking down to see it increases the likelihood of experiencing vertigo.

    --> AeroElectric-List message posted by: erie <erie@shelbyvilledesign.com> I also buld custom home theaters, mostly using touch screen pc's for a system remote. My solution at home (wife hates the touchscreen) is to have a row of buttons on the left, using little clear sticky feet stuck on the touchscreen, she gets 'hard buttons' that she can press for system on/off, volume and source selection....sometimes you just have to think outside the box. erie KITFOXZ@aol.com wrote: >--> AeroElectric-List message posted by: KITFOXZ@aol.com > >Hello Guys, > >My thoughts are that we should not be too quick to write this idea off.

    Subject: Grounding in the Fuel Level System
    --> AeroElectric-List message posted by: "DAVID REEL" <dreel@cox.net> I have a pair of Stewart-Warner sensors for the left and right tank on my RV-8A. Since the sensor is grounded to the wing while the indicator is grounded to the fuselage, I wonder if anyone has encountered measurement problems due to a high-resistance connection between wing and fuselage. The sensor resistance range is 30 to 248 ohms and the indicator supplies about 4.8 volts for a range of about .16 to .002 amps. Is it advisable to bridge the wing-fuselage joint with a jumper strap? Does it matter where the indicator is grounded? How does the sensor find a ground path through all the sealant and gaskets used to prevent fuel leakage? Dave Reel RV-8A

    --> AeroElectric-List message posted by: Gert <gert@execpc.com> No but I had problems with both sensors not making good contact with the tank through the proseal, I ended up putting a ground wire on each sender.

    --> AeroElectric-List message posted by: dennymortensen <dennymortensen@cableone.net> In the days of yore Gateway Computers offered a laptop called a Solo that had a miniature hard wired track ball. The ball was maybe the size of a small marble and the holder maybe 1 and 1/2 inches square. It was extremely handy and easy to use I would love to get hold of something like that again. You just held it in the palm of your hand. I have also seen a wireless mouse that is operated by just moving your hand around in the air and using trigger switches for the click functions. I am thinking of trying something like that when I get that far. I also work with touch screens in my day job and don't recommend them for aircraft use. Actually I don't recommend them for any use. 2 cents and change Denny -----Original Message----- Subject: Re: AeroElectric-List: RE: Touch screen in an aircraft --> AeroElectric-List message posted by: "Matt Prather" <mprather@spro.net> Along those lines, I think it would be slick if each avionics device was designed to be remotely controlled by something like a wheel/hatswitch arrangement on the throttle and stick.

    Subject: Re: Touch screen in an aircraft
    --> AeroElectric-List message posted by: "William" <wschertz@ispwest.com> Some people have tried it to the extent of taking a touch screen computer up in a private plane and then trying to manipulate it during turbulence. They gave up.

It seems with the proliferation of "glass cockpits" that this would follow along. Has this been investigated and discounted for some reason? I believe many of these are capacitive based. Is there too much interference in an aircraft environment that makes them unreliable? Maybe cost? > > Thanks. > Ken > > DO NOT ARCHIVE > >
