The absolutely horrid weather of late (more than 3 ft. of snow ) has kept me pretty distracted, but I have had a chance to finish the guitar project for my daughter. It has been a great project, not without its challenges, and I'm very happy with the result -- so much so that I'm watching an eBay auction for a swamp ash telecaster body for myself.
I won't go through the Grizzly details, (yes, I will stoop for this low pun) instead I'll just mention a few things that can apply to any similar project.
1. When it comes to these high-gloss, exceedingly fussy finishes, every step counts. The places that were glass smooth after the grain filling stage, and after the sealer, and again after the primer tended to be the places that took the final color and lacquer best.
5. If you are using typical abrasives (silicon carbide) for polishing, wet sanding is the only way to go. The paper loads almost immediately when dry and creates little globs that scratch the surface.
6. When polishing, use only the pressure of the weight of your fingers -- if you feel that is not enough, get a coarser abrasive.
7. My backside was saved by the fact that we were creating a "relic" guitar with a slightly distressed finish. If I needed perfection I would have failed. I had hoped to make it perfect as a dry run for the next (non-relic) version but that wasn't the case. But, I really like the way it looks -- used but not abused.
8. Read all Grizzly instructions start to finish several times. The instructions said "now secure the neck of the guitar to the body" at least three times before they really meant it. If I had really bore down on the screws the first time I could have risked losing some grip by the last time.
9. With a couple of caveats, this Grizzly kit is good value for money. The specs were not dead on, but it got the job done. Here you can see that even with the bridge back as far as possible, you really had to back off the string saddles to get the necessary 25 1/2" from nut to saddle. If this isn't right, the intonation will be off.
