Thanks Sully, I have seen this before, but have misplaced the PDF, now I knew it was around here somewhere... -John
I just found one local for $200. I wish I had the cash cause this guy has a ton of stuff and is liquidating everything cheap. Stew Mac Neck Jig Guitar Bass Luthier Tools Luthiere
Just the opposite. The point of the jig is to position the neck as if it were under tension from the strings - typically with a slight relief.
The idea's to replicate the string tension with the strings off and out of the way so that you can do fretwork with the neck under playing tensions for a more accurate fretjob
but you can't file your frets with the strings ON the guitar can you? this jig allows you to replicate that stress pretty closely.. and it allows fom the effects of gravity on your neck as well. ( see, no one plays a guitar in "bench position") I won't do a fret job without mine. which I built my second one in 1998 and its been used almost every day since. one of the best jigs ever devised.
