That's strange because the Brodak Wing Jig Kit uses 5/16" rods.  You would think that any ribs they sell would be sized for their kit.

I got my rods from ACP Composites.

I also use carbon fiber arrow shafts.

5/32 is easy to find.  Its the 5/16 tubing I can't find locally.   I can see it now the postal lady carrying a package of 5/16 tube about 5 foot long.

Most of my ribs have holes for 3/16 music wire. You are limited to 36" music wire, but that isn't really a hindrance in building a straight wing.

If they are 5/32" and approx. 2" apart they could have been set for the old adjust-o-jig

The ribs on my Brodak Legacy have 5/16" holes.  5/16" is within .003" of 8mm, so just get some 8mm OD carbon fiber tube from a kite shop and have fun.

If they truly are 5/32" then use music wire and support in the middle so that it stays straight.

I don't know what's available in the USA but here in NZ I used some contrete reinforcing steel in a jig I made up when I built my Brodak Legacy. It needed a slight clean up with some sand paper but was night and straight and very cheap.

I did the same thing except I used large aluminum 90 degree angle available at Lowes, Home Depot etc.
I cut 2 pieces...cleaned up the edges then zapped them together back to back.
Then drilled the holes for the dowels at the same time to ensure they were in the exact same spot on the angles.
Next I marked the same end of the angles to identify the orientation.
Then I knocked them apart and zapped them into position over the plans on the building board.
My building board is a Blanchard ground piece of steel channel that is definitely flat.
Works great!!
