I built mine from plywood scraps too,  Gary.

 They worked fine. Used one set of plywood flanging  dies to scratch-build the whole airplane, and they're still in good shape...  except the ones I trimmed too much to get into tight places.

  

 I tried using a single bolt to draw the plywood  dies together to form the flanges, but found that I had better/easier results  when I squoze the dies together with some big ol' "C" clamps.

 all flanged up and flying 

  

 "squoze"???

Hay Rick,

      There are all kinds  of ways to press.  Did you hear about the guy who used his car.  He  put the flanging die under one of the front wheels and jacked the car up and  down with an air driven bumper jack.  All it takes is a good   imagination.  And the will to stick with it until you are flying an  airplane you built and there is nothing like it.

This is very "old Hat" for nearly everyone on the  list, but I couldn't resist the opening, especially now that pics can be  attached.  Note the dies are not made of plywood!

 This system worked great.  I still can't  emphasize enough, before flanging, sand the inside of the hole until you can run  your finger around it and feel that it is perfectly smooth.  Anything less  and the flange will probably crack.  I was in such a big hurry to try my  dies that I failed to do this and wound up with two cracks in a nose rib  flange.  Had to make another nose rib because of this, another  lesson.

  

 Regards,

Rick,  

   

I, too, tried the C clamps on the first 3 holes.  In the end I found the ball peen clamp the quickest (kinda like the “200 lb Press).

Randy, I love your 1 ton press. Now that's thinking laterally! Jamie Hyneman would be proud
