I am going to glue the top to the body this weekend, but I wanted to make a jig for this first, because my top is only marginally bigger than the body; I wanted to match up the center lines of top and body perfectly; and the sound holes must be centered above the chamber.

So it had to be spot on! But I noticed when using Titebond, the top piece starts to ‘float’ on the glue when fastening the clamps. This easily results in glueing on the top completely wrong and ruining of all my hard work. The jig should prevent this and also enables me to put clamps around the whole contour of the body. The outer bars hold the body, the upright blocks hold the top and the cut out and legs are for easy clamp access.

I’m also going to mask all of the sides of the body with tape to prevent glueing the jig to the body and to easily remove excess glue.
