Nice try. Points for originality though.An acoustic boomerang.
No but I see where you were going with it.Nut slot jig?
Lol. The nail file will be an integral part of it.Nail file
I recommend offsetting the Carling with StellaWell, anybody can see it’s a modified Fremson fixture, although the use of the asymmetrical barging spring could be confusing to some. It should work great for it’s intended purpose, as long as you remember to keep the Carling off-set constant through the whole process, otherwise you risk perfoloning the master ribs, but that can be overcome in the final coralization with the proper set-up, unless you want to just do it manually. Either way, nice tool!
