Really enjoyed the video - very nice work.
I particularly liked your use of the Domino for joinery where the legs meet the top - nice jig, and it gave me a few ideas.
Nice 80/20 tables and MFT style tops.
I found the setup for the epoxy fill educational. I've done small epoxy fills before using metal ducting tape for backing, but never anything as large as this table.
Yew is listed in the wood database as being a direct cardiac toxin, so I've stayed away from it. The wood database toxin chart doesn't distinguish European yew from Pacific yew, just citing the genus of both - genus taxus. The individual articles on both describe them as toxic. Did you take any precautions or notice any symptoms while working on this project? I know it's kind of a crazy question to ask, but I'm finding that the older I get, the more sensitive I am to dust - seems to be causing more respiratory problems. I'm fighting a cold at the moment whose onset coincided with a long koa sanding session, and koa is considered to be pretty benign, and the last 2-3 colds I've had have also coincided with sanding sessions.
What is the trim router that you used in the video? I've never seen one shaped like that before.
