I currently have four (!) guitars in the queue which need neck resets. So I'm going to cook up a neck removal jig to help with the process.
This is basically a jig that will hold the guitar body during the steaming process and allow pressure to be put on the bottom of the neck heel, helping to press it upward.
Since I always need a plan of sorts, I got one from the Ultimate Guitar Repair web site. Lots of good plans to be found there.
I used 3/4 inch birch plywood left over from the full-range speakers to build the jig.
First I cut the three pieces. Actually four, since two pieces are glued together to make the super-strong piece that will carry the stud that will put pressure on the neck joint.
I cut the pieces and glued them up.
I drilled holes on the rear and top boards where the adjustment slots will end.
Hopefully the routing will go better than it did on the saddle slotting jig.
I also used the router on a low speed. It was a lot easier to control and still cut through the material easily.
The sawdust goes everywhere.
I used incredibly strong contact cement. The cork needed to be clamped to the wood as it dried. The smaller pieces were easy - I stacked them together and clamped the whole mess.
But the big board was harder, due to its size.
Looking around the Dungeon for something suitably heavy, I spotted my AN/URM-25D signal generator.
It weighs 37.5 lbs. Makes a good clamping weight.
'Servscolcom NTC' refers to a Navy Service Training School. From what I gather, there was one in San Diego and one in Illinois. I bought this from a fellow in Arizona, so it's a reasonable guess that it came from the San Diego school.
This unit needs restoration - yet another future project.
