I've mentioned in several posts that this last year or two, rather than house my homebrew test-gear projects in plastic or metal boxes, I've taken to making little comb-jointed boxes from bits of scrap offcuts of oak etc. One or two peple have expressed an interest in the home-made jig that I use, which cost me nothing as it was made from offcuts of timber to a design in a video by the late Roy Sutton entitled 'Making Routing Jigs and Gadgets'. For anyone interested, I've attached a few pics of the jig to show how it's used. If anyone fancied making one, I'd be happy to draw a sketch of the dimensions.
Basically, it consists of two parts:
1) A table with a slide groove routed into it to guide the 'sledge' which move back and forth to cut the combs, with the the router mounted beneath the table. The table has a block of timber scrwewed to the underside of the front edge, which is held in a woodworking vice when in use.
2) A 'sledge' (in two adjustable parts so that the spacing of the combs can be accurately set for a good fit of the two combed pieces of wood), which slides back and forth in the guide groove on the table.
In use, the first piece of wood is held upright against the sledge, which is then moved forward to cut the first groove. This groove is then put over a peg, and the second groove is cut, and this process is repeated until the last groove is cut in that piece. Then the mating piece is place alongside the piece already cut, and the process is repeated until all grooves are cut. With luck, it should all fit together so tightly than it almost needs no glue!
The process makes more sense when looking at the pics.
I'll add a few more pics in another post.
Hope that's of interest.
