I am beginning a project of a rustic dining table made of white oak that has many split knots including one that is about a 1.5×2” hole that i need to fill. I plan on putting a widget of some kind in the hole and fill around it. Thes slabs are 21” wide 10 ” long 2” thick and book marked. what type of epoxy works well for this? I plan on using oil based poly on this for a finish. some suggestions would be helpful, I dont want to screw these up!

I like a 5 min epoxy ill tape it off .put it in a little tin foil mix warm with a hair dryer to thin it poor it in the not wait about 1 min then pull the tape.Then scrape after that when dry.I do one knot at a time. after an ohour it ’s fully cured so you can repeat .

I like a longer epoxy – like 30 minute stuff from the local hobby shop.

I haven’t done any scientific testing, but it seems like the longer curing epoxy doesn’t get as hot when it cures and so has less bubbles in it when it is done. Which may be good if you are embedding a widget of some kind.
