Dick, I've seen an epoxy pinblock repair done in a couple of ways. Both with great results. Method #1. (For isolated repairs): Remove a single string from the tuning pin. Use this as your test prior to removing all of the offenders. Swab the hole with 5 minute epoxy. Put the pin back in and the string back on. As the epoxy hardens, keep turning the pin. If it will work on 1 pin, then probably the others will be fine also. or Method #2. (For the entire pinblock): Remove the pinblock, duct tape the bottom, saturate and fill the holes with epoxy, cure, smooth down the top, reinstall, redrill and restring. Ron Shiflet
