Gnubrid,
I'll set up a picture tutorial going step by step, but in the mean time all I did was:
(A) score along the neck line with a hobby knife.
(B) use large nail clippers to do the rest of the removal the scores give the clippers a place to rest before the cutting.
(C) with pin vise and correct drill bit size to the neck stem I figure where the back of the neck should be the start drilling.
(D) after drilling a little bit I check the depth using my thumb nail at the the point where the dill bit is in the hole and pull it out and see just how long it is from that point to the tip of the drill bit using this a a gauge sort of.
(E) eye balling what I think is the correct length on the neck stem, with a hobby knife I cut the head away from the spur. careful when the knife cuts through that little head will fly right of the table if you don't hold it down.
(F) dry fit. dry fit dry fit. Now for me if I do it right the first time it's like the head fits perfect like it knows where it should go.
(G) once your happy with the dry fitting. I use Super Glue Gel it helps fill any little little gaps and just a little dab will do.
So I hope this helps and by the way I haven't done a head swap in over 35 years I just did it right out of the gate, so don't be afraid use some extra figures you don't like a practice on them until you like your results.
