Thanks for your replies, Jon & Terry. I highly value your opinions. Wouldn't it be just as good to run them through the table saw? The only think different I see the end mill doing is it might leave the surface a little rougher. I initially used PVC-E with poor results. The glue surface did have black paint on it and I'm sure we didn't use as much glue as you are recommending, nor did we clamp. The customer is really unhappy (understatement) and I am wanting to make sure we get it right this time. I thought epoxy would give that to us, but Terry is telling me the epoxy won't adhere well to the plastic. So, based on your responses I'm thinking fresh/rough wood (no paint), more PVC-E glue inside the cavities and clamping will make the difference.

My inclination is to saw off all that are remaining and epoxy on a new set. What would others do? Plane the surface and glue with PVC-E. Don't rely on gluing the surfaces together but place some glue in the cavities of the sharp and clamp/tape and let the glue form the bond from within. Don't pool the glue in there, just enough to drip down and form a meniscus at the joint. Planing can be done on a drill press with a router bit and holding the key in a drill press vise. jpg attched. An end mill bit works best. Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
