Talked with Ben Taylor to confirm Fly-In is open to anyone. There may be asmall camping and or registration fee. The road closure is betweenBlakesburg and Ottumwa. If you are coming or have questions contact Ben atBenjaminlTaylor(at)yahoo.com It should be a great time!JackDSM All,Antique Airfield will be holding the 4th annual Homebuilt Fly-in at IA27 on July 2nd and 3rd.The flyer is attached.Cheers,Dan-- Dan YocumFermilab 630.840.6509yocum@fnal.gov, http://fermigrid.fnal.gov"I fly because it releases my mind from the tyranny of petty things."________________________________________________________________________________Subject: Pietenpol-List: Stearman incident in DC Monday

Saw them flying overhead towards Reagan National Monday, but did not see this untilit hit the news. Both guys walked away.

Dan,You could have an electrical tach, but most small Continentals in airplanes like Pietenpols use a mechanical tach. The cable is driven from the rear of the engine, hopefully through the cockpit, probably to a right angle drive on the back of the tach.My old cable was slowly destroying itself, and I'm assuming causing excess friction inside the housing. Thus my increased tach reading with the new cable. Maybe some of this applies to your problem.Perry----- Original Message -----

Ryan is correct - the tach cable just nests inside the oil pump shaft with a1/8" square peg fitting into a square hole in the shaft. Any fraying orbreaking of the cable is almost certainly NOT in the end of the cable thatplugs into the gear shaft since that portion is contained within theaccessory case and cannot flex much. Any break is probably where the cablewas bent too sharply to fit around something. In a Pietenpol, since theengine end of the cable is almost on the aircraft centerline but the cablemust make it around the front cockpit to get to the rear instrument panel,there are some significant bends required.Jack PhillipsNX899JPRaleigh, NC _____

Dan if the tach is steady...not bouncing around my $0.02 is either the magnet isgetting weak or the tach has internal friction. Wish you were near I would loanyou mine to test it. The needle is removable and could have slipped. Not toolikely.--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009Ribs and tailfeathers doneusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 10 Jun 2010 20:13:16 -0700 (PDT)
