It's time to get back to work in the real world. Here is a Mosrite body, almost completely recovered from its brush with water-based polyurethane. Stick with oil-based, water-based is junk.
This one went through a long and torturous build process over almost two years. All I can say is don't believe the "advice" you find on talk_ass. However, in the end, it turned out to be a pretty nice instrument.
This is the jig as I first built it, with a drill guide attached to the end. That doesn't work very well. The jig is made from 1x2s, 1x3s, and MDF for the base, mostly scrap. The eye bolts are used to secure the workpiece. The new router plate makes the centering block obsolete. Yesterday I sank a dozen screws into the jig itself to stiffen it, re-glued the rails, and semi-permanently mounted the pine spacer under the neck.
