The engine is the Akron Motor Works Model "E", Ford B block inverted,Used in theFunk airplane.The water pump is a 2 blade impeller 4" turning at 2X engine speed.A very highvolume pump. The testing is not complete as flights have not been done for finaldata. Don Sweeney is still looking for a down draft carb which has a largeducting to the manifold that came with the engine.This is the same type engine I had in my 1998 Piet that I flew to Oshkosh.There were no problems in coolant flow. As of this date.Pieti LowellRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/9_09 ... __________

Merry Christmas, Piet pilots and builders! Hope everyonegot something Piet-related for Christmas this year ;o)We have been running some vibration testing on the A75. Ihave the cowlings off the engine to take care of a numberof little things so I took advantage of the opportunity and installed the DynaVibe instrumentation in order to checkthe tach calibration and vibration levels. As expected, thetach is reading high... 100 RPM high at 1000 RPM and 200 RPM highat full power. Good to know. The vibration reading showed0.51" IPS at 2350 RPM with the heavy spot at 336 degrees, soyesterday we pulled the two bolts that are across the hub fromthe heavy spot and inserted the next size longer AN6s, alongwith a stack of 4 washers under the heads of them, and ranthem back down. Warmed up the engine and ran it up, and findthat the vibration has reduced to 0.26" and the heavy spot hasshifted radially counterclockwise just a bit. Now we'llfabricate a sort of steel 'flyweight' to go under the headsof the two bolts across from the heavy area, make it just abit heavier than the washers and longer bolts that wereadded, return to the standard bolts with the 'flyweight'installed under the bolt heads with a standard .063" thicknessas AN washers, and run the test again. The goal is to get thevibration level to no more than 0.1" IPS. I'm very curious toknow how detectible the reduction in vibration will be inflight. Hope to find out before we leave on our dive trip toBonaire on New Year's Eve.The engine runs very strong. Also installing intercylinderbaffles, which were not installed during the rebuild andwhich may not be necessary but I think they are.Oscar ZunigaAir Camper NX41CC "Scout"San Antonio, TXwebsite at http://www.flysquirrel.net ________________________________________________________________________________Subject: Re: Pietenpol-List: Re: Sweeney's Radiator

Jerry, I downloaded openoffice.org but when I try to open the xl document I still get a block that tells me to "create an association in the Folder Options control panel." Do you know what that means? I am pretty much computer illiterate.----- Original Message -----

while welding some 4130 yesterday, I somehow air hardened it. At one time I worked in a machine shop where they annealed metal and carbide after heating it in induction heaters by shoving the parts into some type of powder to insulate it until it cooled slowly. For the life of me I can't remember what it was. Does anyone know what it could have been? Lime possibly? All my welding books say is to leave it in the furnace and lower the temperature 50 degrees per hour. I don't have a furnace, just a torch. Any help is appreciated.Dennis________________________________________________________________________________Subject: Pietenpol-List: Re: Sweeney's Radiator

I know very little about Zenith down draft carbs, but what about your typical VWcarb? I believe they are some version of Zenith downdraft. I even have one inmy garage in some junk. I have no idea of capacity but they are common.and ifneeded I could sure ship it. RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Jack, you're a prince. Thank you. That is exactly what I will try to do.Incidentally, I was a Technical Writer (Electronics) for about 30 years and I perceive that you would have made a good one. Thanks again.----- Original Message -----
