PJJN
Plate Joining Jig for instrument tops and backs
$188.95
Our Plate Joining Jig (PJJN) has some slick 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 that can be easily disassembled for storage. The base of the jig is constructed from non-stick HDPE (high-density polyethylene) and the top is protected by high-tech Kapton® tape.

Product Description
Video: Using the LMI Plate Joining Jig.
We have used these jigs in our shop for years 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.

Fantastic!!
I am using this tool to glue up a set of guitar plates for the fifth time. Just a breeze to use. If one has taken the time to prepare the center join well, this jig applies applies firm pressure to insure a great result. No more trying to fumble with clamps on thin tops and backs. The wedges allow for fine tuning the downward pressure. L. M. has once again turned a brilliant design into a tool that is easy to assemble and use, and as always, Robbie O'Brien's demonstration of its use is very clear. Well done, you guys! A real home run.

Some issues with machining of parts
The base frame components fitted well but the top frame machining was not vert precise.
There is slight offset from perpendicular between some slots and the flat edge of the frame.
The assembled frame has a very pronounced twist.
This also results in lack of pressure across the joint as one side of the central Teflon non stick strip is slightly recessed and does not make good contact with the wood being joined.
I am a very experienced woodworker and can remedy some of the problems but am not sure if it would be better for me to return it for replacement.
