So what does this jig do? It holds the clamps in place while you apply glue and laminate pieces for a neck blank. Once the clamps are tightened, you can remove the jig.
I wish I can take credit for this great jig but I can’t. I first saw this jig in the documentary called Restrung.
If you have not seen Restrung, I highly recommend it!
