I have an accoustic guitar that my son fell on and broke the neck, I want to repair it as it has been in the family quite a long time. On you tube, they show different videos explaining the procedure, but they don't tell you how to build the neck removal jig. They want almost $90.00 to buy one and I don,t plan on using it more than once which does not make it cost affective for me. Does anyone have details to do this? Thanks Dan
