I haven't seen a cut list for an 8-frame box, but I think I've got it figured out. I'm no carpenter or woodworker so don't laugh if I've got it all wrong, ok?
Here's what I understand as of now...
Using 3/4" stock the outside dimensions for an 8-frame 6-5/8" super are 19-7/8" x 13-3/4".
The boards for the 13-3/4" ends are actually 13-3/4" long and have a rabbet 3/8" wide (1/2 the wood thickness) and 5/8" deep running the length of it for the frame shelves/holders. At each 6-5/8" end there is a rabbet 3/8" wide and 3/4" deep.
The boards for the 19-7/8" sides are cut 19-1/8" long. The two 3/8" thickness of the short boards' rabbeted ends make up the other 3/4".
So to summarize.... I cut the long board to 19-1/8" long and the short board to 13-3/4". I then cut the rabbets in the short board for the frame shelf and rabbet joint, slap some glue on the ends, put it all together, nail/screw,....and a super is born!!!!
This ends up giving the inside dimensions of 18-3/8" x 12-1/4". Right?
Is that pretty well it? I just wanta get it right the first time...if I can.
Thanks for the help!!!
