It looks like Mony and Christopher have supplied all the info you need.
Larry- if you have a band saw with a narrow blade, I don't see you why can't: 1) set the table at 45 degrees, get a piece of plywood the correct thickness and cut the beveled (45 degree) female and male part of the die at the same time. 2) Use sandwich construction (wood glue/ screws) on the female portion same as on male portion as mentioned by Monty below. sanding smooth and ensure proper radius.--------
I used the bolt & large washer method. I used 3/8" FINE thread----
The advantage of wood is the side of the die can easily be trimmed down to fit inside the channels ( was necessary on the 701).
Don't be surprised if the flanged part is slighly distorted (slight bow) on the wing ribs etc--- many holes close together---- I used "L"s on all my wing ribs, same as Chris shows for ribs 1-4 ( walkway). SPEAKING OF WING WALK AREA-- I suggest you folks get with MARK TOWNSEND and get his opinion on this--------- I know I followed his advise.
Where did I get my plans for the dies? My 701 plans update was 1990, at that time Chris included the plans for scratch builders to make their own dies. That info was on page 7.G.3

[quote]attached is a file drawing for plans for flanging dies from RSW eng. for
metal ones. But they can be made from wood as well.
The female die is fairly easy to make as one piece with a router and
mating camfer bit...if you have one and also possible with a drill press I
would guess.
The male side is easier to make as three separate flat pieces then both
glued and screwed together.
3/4 hardwoods work the best followed by 3/4 plywood.
And for us that will only use them a few times. Cheap particle board
works very well too. Mine and B. J. Swaller's are 5/8 particle board left
over from carpet underlayment jobs......with scraps of thinner plywood
mixed in. B.J. made his on a drill press.....
They don't have to look pretty to make a nice flange.
Align the dies and drill a hole threw the center for a bolt and big flat
washers to squeeze the dies and form the flange. or put in a shop press
or large arbor press.....
You get the idea........
