Pietenpol-List: plug wire test ?

Post by matronics »

Original Posted By: Oscar Zuniga
Subject: Pietenpol-List: plug wire test ?Any way to test copper stranded core spark plug wires for the simple A-65 with unshielded (Eisman) mags ?After testing all the plugs (all good) in a pressurized spark tester, insuring timing was correct, and cleaningand gapping both points I'm still getting a 125 rpm L mag drop. Mag cap is not cracked, all in order inside mag.If it was the condenser I'd be seeing point burning which I'm not.Thinking of just going to Autozone to get a generic automotive set and re-soldering the mag and plug end terminalson the bottom (L) four wires.Mike C.________________________________________________________________________________

There are no inspections or permissions required from the FAAto begin building or continue building your experimentalhomebuilt airplane. There used to be a requirement for "pre-cover" and other progress inspections, but the onlything now required is a final inspection by an FAA inspectoror an FAA "Designated Airworthiness Representative" (DAR).However, as others have pointed out, it is very useful andstrongly recommended that you have an EAA Technical Counseloror other experienced builder look over your project fromtime to time and certainly at key points in the construction.They aren't there to criticize your work... they are thereto help with tips, ideas, and suggestions... and to pullyour bacon out of the fire in case they see something thatmight compromise airworthiness.There is a requirement that you document your constructionprogress. Keep a log, take photos, keep receipts and notes-because you need to be able to demonstrate that the airplanewas at least 51% amateur-built as the FAA defines that. Notthat it was 51% built by the same amateur (you); it can besold or passed on from builder to builder until completed orit can be built by siblings, friends, or as a group project-just not "for pay" nor using large subassemblies fromcommercial airplanes.Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net ________________________________________________________________________________Subject: Pietenpol-List: Re: plug wire test ?

Hey Mike,I think your buddy Don Helmick might have a set of unshielded plug wires. Also,if you'd like I have a spare Bendix lunchbox mag freshly overhauled, that you'dbe welcome to use until you get straightened out. It has an unshielded harness.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 15 Jun 2010 10:40:44 -0400

Subject: RE: Pietenpol-List: plug wire test ?All good suggestions-thank you guys. I'll look for that unsuspecting helper Steve. We have a few winners out at the airport who would fit the bill nicely andit might stop them from coming by and telling me unsolicited stories that never seem to end.Last year I found a fatigued solder joint/wire to plug clip connection prior to Oshkosh and simply resoldered it to a freshly cut strand of copper core wire.I'm thinking of making up one new L mag wire and rotating that among the bottom plugs to see if I can find/eliminate the offending wire.Good suggestion on swapping mag caps though both appear sound. Never know.Yes Don, Don Helmick said I could bring my wires down and he'd test them. He let me use his pressurized spark plug tester last week. Thanks for the offerof the spare mag. Right now I've got your right hand man and mine coming out Weds. night to troubleshoot w/ me--- Bill Klosz. He loves telling the storyabout how many times they tore down your engine to find that plugged oil galley !Like Bill says they can do any job and the impossible jobs just take a little longer. His other saying is "good enough for who it's for".Mike C.________________________________________________________________________________Subject: Pietenpol-List: Re: plug wire test ?

Wood requirements for cut-to-size sticks are fairly straightforward, and the listsreferred to by Ryan are pretty accurate.Working with rough-sawn lumber is not so clear-cut (no pun intended), because thesizes are not standardized (hence the name). I bought my Sitka as 8/4 planks,and actual sizes varied from 2" to 2 1/4" thickness, and widths from 5" to7". By making minimal passes through the thickness planer, on one board I wasleft with 2 1/8" finished, which yielded two 1" thicknesses. If you're buying1" rough boards, you will likely only be left with 3/4" or maybe 7/8" after planing- which will not be thick enough to yield the 1" x 1" longerons.As a reference, so far I've bought two 20-foot 2" x 6ish" planks, and two of AircraftSpruce's "bargain bags of spruce", which should be enough to build thestructure (minus spars) once .

Dan,I don't know what you are looking at for a timeline in getting it put back together, but if you are trying for Brodhead you may want to call up Poplar Grove Airmotive and see what they have in stock for cylinders. If you weren't overly concerned with getting that exact same cylinder back they may have an exchange cylinder done and sitting on the shelf waiting to go. Sorry to hear the bad news.

Mike, the lead tester used for shielded wires should be able to be used for unshieldedwires also. My best guess is you have a wire with a break in the wireitself, or the insulation is breaking down, and arcing to ground, somewhere betweenthe mag and the plug. Best guess would be the latter choice, and couldeven be several wires arcing to ground. just enough to give you a weak spark.The testers we had at school, didn't seem to hook up like you would think they do. I remember if you hooked them up the way it appeared to supposed to be, you would get a serious charge out if the deal when you pushed the test button. Aircraft Tool Supply carries a tester here: http://www.aircraft-tool.com/shop/search_result.aspx that is used to test high tension spark plug leads. It may be available elsewhere for less. The reason I looked at their site, is they have a package deal with a timing light, the lead tester, and some other stuff, and that is the package the school had.--------Long flights, smooth air, and soft landings,GliderMike, aka Mike GlasgowRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 16 Jun 2010 07:45:05 -0700 (PDT)
