yeah, the epoxy is a useful tool. I used it one other time for our barnwood dining room table (that wood had some serious rot to dig out and repair!)

Ok, here is the spalted pecan...nowhere near the amount of woodwork you have on your piece (I'm but a humble amateur woodworker), but the wood was special and had some beautiful fungus stains :)

First time I've used industrial piping on a table (used it on this huge checkerboard cutting surface I made for our kitchen), needless to say it is a very sturdy table.
