I’m making a small coffee table for my father in law from a 40 year old cross cut cherry slab that he took off his fathers property. He’s kept the slab in good shape, but it inevitably cracked in several places.
I doweled the cracks from the bottom and have been working on the inlays for weeks. Large inlays are not good for copper powder filler, you have to prefill it with something else and then hope you can get the copper to hold on through the finishing process.
My tools for this are two DeWalt sanders, one a 5” ROS and the other a sanding drill capable of taking off large amounts of wood quickly. If you keep it moving, it keeps a level surface. This drill sander was necessary as the cherry is extremely hard and the CA glue had to be removed to a minor depth. Any dips, although minor, have been feathered out.
I was going to use a pour on poly, but the more I think about it, Arm R Seal satin poly is better.
My question is, can I add a hardener to the poly to give the surface even more hardness and if so, which one.
Here are some pics of the slab. The legs are in glue up and I plan to turn them out from 12/4 cherry, or 5×5 more or less.
This is after planing and sanding to see what I had to work with.
This is the bottom where the cracks were stabilized with 3/8 maple dowels.
Cleaning up the cracks for filler and inlay.
First inlay on, but it didn’t look very nice afterward. Later I re-inlayed.
This is what it looked like after the first attempt at the inlay.
This is after the second inlay attempt, sanded to 400g and buffed only, no finish.
Can’t wait to see this finished.
This is after the inlays were touched up. I think it will stay this way now.
The middle void.
This inlay was the problem child. I made the mistake of filling it with sawdust which I thought would harden with some CA glue, but it was very slow to harden. I think it’s stable now, but time will tell. If it hasn’t moved by the time I’m finished with it, it should be okay.
I flipped it over and finished a small part of the underside with Arm R Seal poly satin just to see what it will look like.
