This letter came in from Pietenpol builder John Francis:
“William, I attended CC #20 and was happy to have my case checked out by Roy and get it assembled. I am slowly gathering the parts I need to complete the engine. What engine components are necessary to have my engine running at a Corvair College? Or, perhaps it would be easier to list those I don’t need ie carb, alternator, prop, etc? Perhaps as you publish the numbered groups you could put an asterisk by those that are needed to get an engine running at a CC college.”
Above 49 of the 70 Corvair builders at CC#20 in Hillsdale MI June 2011.
John, Thanks for your note. Looking at the photo of the builders at CC#20 brought back a lot of memories and made me think of all the things we will get done at Colleges this year.
John has a very good on line builders log with lots of pictures of his project. I borrowed this one of John at CC#20 from his site at : http://www.mykitlog.com/kringle/
I borrowed this one also, it shows Johns ‘closed case’ with an original Dan Gen 1 bearing installed. This is one of Dan’s original housings, the first 120 or so were heat-treated castings. Today they are made from CNC billets of 6061. Dan made the switch to take out a lot of the different steps in the manufacturing process like working with a foundry and heat treater. They cost more to make as a billet, but he kept the same price to builders.

…..You are correct, it is easier to list the things that live on our run stand that a builder doesn’t need to bring. Looking at the above photo from#23 for reference, the test stand comes with:
Full exhaust system.
intake and carb and throttle connections, and hardware.
its own self-contained fuel system.
All the ignition components except the distributor.
It has its own bushings and mounting hardware.
the stand uses the cooling baffle on all the test runs.
Propeller and mounting hardware.
