The tuner with no reaming of the hole :
After :
Once the holes (and I only did the first and last hole at first) were opened up enough to seat the tuners, I can see that my first peg is too short.
Which means the head stock is too thick up there. It's 0.6025" there and 0.5905" at the end. I'll need to sand that to 0.500 I guess. But I had what I needed to do the job I was trying to do.
What I'm doing is lining up the location of the bridge.
I attached the first and sixth peg to the head
Made sure to align the hole in the peg perpendicularly to the neck
And got out this spool of conductive thread I had from when I was making my gloves touch screen capable...
Only because it was the only thread I could find that was thick and strong enough to do what I wanted it to do. Some guys will use guitar strings for this next part.
