Testimonials

"Just received my latest classical guitar kit. I had a couple of requests for wood selection, and you did a great job in selecting on both counts,
In addition, all the wood was great quality - this was an expensive kit, but your product made it a very good value to me.

Thanks for the great work!"

Plate Joining Jig

JoiningJigPJJNaZOOMOur “New and Improved” Plate Joining Jig (PJJN) has some slick new features you will enjoy. The unit is self-contained and does not need to be bench mounted. There are holes machined into the base so it can be temporarily clamped to your bench while joining your back or top. Once your plates are glued up, you can create space setting the jig aside while your glue dries. The PJJN is a simple, robust, bolt-together design which can be easily dissambled for storage. The base of the jig is now constructed from non-stick HDPE (high density polyethylene) and the top is protected by high-tech Kapton® tape.

We have used these jigs in our shop for year to join backs and soundboards. The process is simple. Just joint or plane the edge of the board to be joined. Sand it for a perfect fit. Place it in the jig and put the lattice over the top making sure the joint is flat. (1) Lace the lattice and base together and insert triangular tighteners. (2) Gently hammer in till the fit is tight. (3) Allow glue to dry and voila, a professionally joined top or back. We use our LMI FGX glue exclusively for this purpose with great results.
