Pietenpol-List: babbit

Post by matronics »

Original Posted By: LanhamOS
Hi all In my work we have on occasion rebabbitted bearings for large steam turbines.When we do this we heat,flux and tin(with pure tin)the bore of the steel shell.Then we spin the heated steel shell in a lathe. It has dam shields at the ends.Then we pour the babbit in and it sticks real good.What i'm wondering is how do they do this to a model A engine? I'm also curious about the distributor hole. Does someone make a magnitothat plugs in there. I've never looked close a Ford A engine. Does it have adistributor hole?I sent away for plans yesterday to Don Pietenpol. Now the long wait!Cheers Steve Yahn________________________________________________________________________________

For Steve... thanks for the news about the babbiting process. I alwayswondered howit worked.As to the mag on the ven4rable A Engine.. EAA publishes reprints ofFlyi9ng and Glider Manual...the 1932 issue features the Pietenpol, with textby that applied engineering genis himself, Bernard Pietenpol..The Adistributor looked like a bat wing, withj copper leads to each plug.. So thisdoesn't work, although in the VW conversion the mag fit into the distributor drive.. Instead the A engine isreversed in the Pietenpol, prop runs off the flywheel end of the engine, themagefits into an adapter on the end of the crankshaft pulley that drives thewater pump...Bernard had detailed instructions as to how it worked.. It used athreaded end of a Model T Rear Axel, with a soft leather unversal jointcoupling. Myfather had Midel T'w, and an A. I had am A.. So, wonder where youwould get the end of the T rear axle, but I am sure a good machinist couldfashion one.One amazing piece is the power curve of the Ford A conversion at1600 rpm.. I am curious about some conversions of A engines whowing a waterhose at the front of the reversed engine.. Good, luck..If you need the article.. I can supply. Dr. O.
