I purchased a set of aluminum wing and fuselage jigs but they will need to be mounted on a melamine or similar material bench top.  I have read here where many builders use a glass top right over the plans to build upon.  That isn't possible without gluing the jig parts to the glass, which wouldn't allow adjustment.  It seems that one must make a choice between building over glass protected plans or jig building over the bench top.  Your thoughts will be welcomed.

Dick,

I took a chunk of Melamine (1") and used a router to cut slots for my jig legs. I level the board with a laser level using shims. Once it's level I adjust the jig legs. Works.
