“Dear Sir, A few months ago I placed my first order with you and built my very first guitar. Ovangkol back and sides with sitka top. I have been a craftsman for a number of years, rebuilding antique pianos, including making new soundboards and bridges, and decided to try my hand at guitars after buying a Taylor 814ce. The results of my first attempt were surprising, to me and to others. Since I'm a bit "old-school" I built it entirey by hand, no table saw, router, joiner etc. (I did use a driss press!). I have already received requests for custom made guitars, and from a store interested in selling them. It really helped to find quality supplies, all in one place, so I could start this experiment - which may just turn out to be my next and final career. Many Thanks. ps. I have just placed a second order so I can start making a few more......”
Our “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.
