  William, Pierre, I googled the Epotek 301 and found some information, but can't fine a source. Where did you get it. Sounds like a handy product to have on hand.

    Pierre,

    Based on what you are describing, you're trying to fill between laminations on a pinblock.  For that, I'd suggest any epoxy would do the trick, so long as it is thin enough to allow capillary action to pull it into the delaminated areas effectively.  So if your epoxy is thin enough, go for it, but having used Epotek 301 (sparingly) I can tell you that it is about the viscosity of thin CA glue - almost watery and as such is super for getting into cracks, etc.

    Are you planning on filling, or lining the old tuning pin holes with epoxy as well?  If so, for that application I'd recommend something thicker.  However, after attending to the delaminations, I would probably recommend just drilling the old block out for oversize pins rather than "epoxy swabbing" the existing holes.  Of course, maybe that was your plan?  Enjoy the experience.

      I have a cheap grand to restore.  The kind that does not really worth it.  I'm doing it to learn and practice.  For simplicity (and economy), I'll try to fill the partially delamited pinblock with epoxy.  I saw the Epotek 301 is a recommanded product.  I'm trying to order some.  But what if I use standard epoxy.  I use 5 to 1 regular lamination epoxy for a lot of general work.  It work well on wood.  We used it for building boats (epoxy on cedar).  the question is how will it hold pin torque? Any recommandations before I try it?
