Thanks for all the replies and information. They are easier to acquire than I thought. I know lots of older designsn used them, and I figured junk boxes and spare parts bins all over the country had one or two in them if needed! I haven't had a chance to check my stuff yet, and I probably have one or two. Even boreing the props is no real problem, as Jim Lee make prop bushings, and I can make those also. My only questions was if he needed something special or different, depending on what he's using for a spinner. I'm no where near starting on mine, but what ever we figure out, I'll buy what I need and store it in the kit box!
Thanks again eveyone,
Dan McEntee
