I went to a copy place called Sir Speedy. I wanted to copy my Speedy Bee plans so I can make scratch building templates. They informed me that they can increase or shrink the size of the prints with a touch of a button. I would like to make a 40 size with a 60" wingspan, that would be an increase of 150%. You would have to play around with the size of the wood using. The 1/4" square strips would become 3/8", the 3/16" square strips would become 9/32" Can you find 9/32 square stock? Never checked. I think it would be very cool. Thought I would pontificate endlessly again about the Bee syndrome!
