so yeah, i guess i screwed up with my router on my second pass and i cut the neck pocket a little bit too deep (~1mm). What's the best way to shim/remedy this? Thanks.
Did you make the neck? I'd just take a 2mm thick piece of maple an laminate it to the neck heel, then trim it with a flush trim bit on the router.
If you masked off the neck slot, you could pour in a small amount of "Por-A-Kast" polyurethane resin. It's a 1:1 mix that pours like water, the air bubbles will surface and disappear. It's sandable and machineable to boot! 1(800) 628-7296
Stick with adding thickness to the heel. Laminating to the bottom of the pocket would be tough to get precise. Using a poured liquid resin would be hard to get a perfectly flat surface - and who knows what the tonal effect might be. Laminating to the heel should be nearly foolproof.
