Very cool!

These voids were filled with System Three MirrorCoat epoxy. This epoxy marketed as a "bar top finish" and is formulated to have a very long working time once mixed. This is so it will have time to completely level itself when poured on a large surface (like a bar top). This property was great for this application, because there was a network of voids in the wood, and the epoxy was able to seep through and saturate the inards of the slab which enhanced the structural integrity.
I masked checks, knots, etc. on the bottom surface and then poured MirrorCoat into the major voids on the top surface until they were filled. I thought I was done, but when I looked 15 minutes later, the voids were half empty. I had to add epoxy several more times over the course of the next couple of hours. This epoxy takes a good 24 hours to cure and I found that even longer is better before using a cabinet scraper or sandpaper. The table is a few years old now and there has been no shrinkage or other issues.
Very nice table. You did a great job!
Sorry my message is so long, I didn't have time to write a short one.
