The angle cost me around $175.00 for both pieces ( I think I caught my metal supplier on a good day ! ) and the rest is straight from Home Depot. The 2X4's, 1" top, bolts, etc. topped the jig out at approximately $ 300.00 give or take.
I made my top clamping pieces out of 1" ply ( they seem plenty sturdy ). I had an extra piece in the shop and on one side, ironed down some of the same type of laminate material I used on the rib jig, then cut them to size on the table saw. Between this and my stockpile of wax paper, i should be able to keep any accidental gluing to a minimum !
