RE: 2 mm and 3 mm plywood
I received the following email from the good folks at Bud Nosen Models:
"This is what I do know. We import all our plywood from the country of Finland. It comes into us in mm not inches with the exception of the Italian Poplar (or lite ply). Our vendor tells us at this time, there is only one manufacturer of this type of plywood in the world. (finding that a little hard to believe, but ok) We convert the mm to the nearest imperial size as we believe most of our competitors do.
I don't really believe that you can get a true 3/32 (at least not from the company we are dealing with), but I do have a call into Bud as he is not in Minnesota at the moment. "
Case closed ! I believe it when she said there is only one manufacturer. It would be interesting too know what the airplane manufacturers in the far east are using though.
