Well, me too on hearing (all from EAA staff A&P's) that powder coating hides cracks,so they don't like it. I am NOT relaying my opinion on whether or not it's a good idea or not, mostlybecause I have no clue! These guys pretty much only play with old stuff, finding and fixing cracks andsuch. BUT, I hate how all the small parts on my Piet (like the flat plate fittings thatdon't even have welding on them) eventually get looking "icky" and I'm prettysure they'd stay nicer looking if powder coated. I fly off a lot of grass and everything on the bottom side gets wet. Seems thecorrosion prevention would be an asset not yet mentioned.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 27 Feb 2013 06:10:03 -0800 (PST)

Gary, I am assuming that the eight washers move the fine 1/2 inch (1/16 inch for each washer). Correct? If so and you were rebuilding right now how many more washers would you use? I am at the point of displacing my fin and might as well get it correct the first time. Chuck----- Original Message -----

Ken, I just asked Gary the same thing. I would think off hand that 3/4 inch would be a bit much. I'm thinking of about 5/8 inch. Most of the posts I have read from people who use a smaller Continental engine I gather that they are offsetting the fin about 1/2 inch. I'm thinking that if Gary used regular thickness AN washers he displaced his fin 1/2 inch also which, as he said, is not quite enough. I would think that with 3/4 inch you would have to hold a slight amount of right rudder in cruise which would be counterproductive. Chuck----- Original Message -----
