A router jig for making comb-jointed boxes

[Yorkie]

I've attached a few pics of homebrew test gear that I've made in recent years, housed in comb-jointed boxes made from scrap offcuts of oak. They've all featured on the forum at one time or another in the home-brew test gear section, but I thought if I posted just the pics of the boxes again in one post in this relevant thread, it might give a better idea of what can be done with a comb-joint router jig.

I claim no credit for the jig - it was designed some years ago by a noted UK router expert - Roy Sutton, sadly, no longer with us.

Hope the pics are of interest - inspiration even!
