I just finished resetting a Yamaha neck and need to do a little finish touch up. Wondering what I should use that will adhere to the old finish. I'm thinking lacquer might be the best way to go but also considering poly.

Have you considered GluBoost and Kovax Tolecut abrasives?

I've found them excellent combination for touch ups on many finishes. And no waiting for lacquer drop fills to dry

Were you successful in resetting the neck? What model? Come apart OK? Did you have to angle the steam injection needle?

Old Yammies were lacquer - that is what I would use. If its newer I would test first.

I finally strung it up and was surprised to find the action was still high on the high e strings. When I checked before stringing it up with a straight edge, it was well above the bridge but after stringing it, it was below the bridge. After checking the relief I found there was plenty of room for adjustment so I cranked about 3/4 turn and that helped. Brought it to about About .110" on the high E and .09 on the low E. I think this is OK for a 12 string but I also found that after clamping the fretboard to the body that it looks awful and I don't think I can live with that much fall off so I'm going to un glue it and add a rosewood shim. I may take the neck off again and increase the angle.

Your thoughts

The guy was happy with the rest and plays beautiful. He wants a shim under the fretboard though and offered to pay the extra.

Is the fretboard currently floating?

No, I glued it down. Time to learn to make tapered shims and scrape out glue.
