The Martin is slowly but surely coming together. I don't know if you're tired of reading about it, but I'm reaching the point where I want to see it together - mainly so I can play it!
Last week I took a big leap towards conclusion.
It's pretty clear that someone has done a good clean job taking some material off the dovetail. I need to shim the dovetail a bit to get a good fit - not unusual. I stuck some pieces of card stock into the joint as a dummy shim, and measured them. About thirty-five thousandths of an inch thick.
Since the joint is blind (i.e., I can't see into it when the neck is attached), I need some way to measure the tightness of the fit, and determine what needs to be shaved off.
Take a couple of pieces of carbon paper and put them in the joint.
Then slide the neck into the joint.
I had to do this a lot - maybe 30 times - and each time the marks changed, and the dovetail fit got deeper and better.
Next I'm going to try and rig up a jig to hold the neck in place so I can string it up and get a good look at the neck set.
