I purchased my (7) 1 x 6 x 20ft planks at McCormick Lumber with the help of BillRewey, known expert Pietenpol builder. We ran the planks through the planerat McCormick, just a light skin cut and ended up with very nice 1" thk. sparquality planks. Enough wood to build the whole plane. I cut all my rib strips,fuse longerons etc. on a 14"Delta bandsaw. I'm using West products epoxythroughout. A 1 qt. kit should be adequate to build the whole plane. Plywood gussetsstapled on with an office paper stapler. Works on both 1/16" and 1/8"birch plywood. just press down. No need to "bang" it. A lot faster and easierthan a million tiny brads.________________________________________________________________________________Subject: RE: Pietenpol-List: spar idea--sketch attached Date: Wed, 18 Jan 2006 09:28:49 -0600

Just thought I'd throw in a little levity for the day. I was trying to imagine how Mr. Pietenpol would take the news if, say, General Motors came out with a notice that the crankshaft in a Corvair should be nitrided to prevent fatigue-induced cracks. So here's where my mind went (thinking back to the old Flying & Glider Manuals)."Took an empty tractor grease pail and gave it a good cleaning, then put my Corvair crankshaft in and packed it in real full all around with cow manure from the feed-lot. Figured it would be pretty rich in nitrogen from the feed and clover the cows been eating. Put the lid on the drum, filled 'er with air from my compressor, and set 'er in the sun for a couple of days to let the nitrogen soak into the crankshaft. Other than a bit of ripeness when I opened the pail to retrieve the crank, everything was fine and I cleaned the crank, buttoned 'er back up and went flying. Don't believe GM would approve of the cow flop treatment, but I'm flying just the same."Back to repairs on NX41CC ;o)Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________

Thanks Oscar I needed that.I have now about 25 hours on my Corvair.When I rebuild it I decided not go with a nitrided crank, on advice of manyexperts, the non-nitrided was good enough.Goes to show you "good enough" is a term that should not be used inAircraft building.So, now I am out hunting for Corvair parts again.Might already have located a rebuildable engine and will pick it up thisweekend.I will use the crank after getting it up to AD compliance.Now all I need is that grease pail and some cow manure.....:-)Hans "Oscar Zuniga" To Sent by: pietenpol-list(at)matronics.com owner-pietenpol-l cc ist-server@matron ics.com Subject Pietenpol-List: BHP and the Corvair crank 01/18/2006 09:23 AM Please respond to pietenpol-list@ma tronics.com Just thought I'd throw in a little levity for the day.
