We are building a bar top and will be applying epoxy after we apply 2-3 coats of poly. My concern is not all the wood pieces butted up to one another and am afraid the epoxy will seep through the cracks and will not level correctly. What do I do to fill the void or do I need to?

Don't know if you did the epoxy pour yet. What most of us do is apply a good wide painters tape to the underside. Still lay down plastic incase of any drips. You cannot get the epoxy off the floor easily if it drips to the floor.

Here's a some pics of a tabletop, countertop and bench we did a epoxy pour at a resort near us. All had painters tape on the underside before the pour. If you use a paints tape that does not stick very well, the epoxy will seep though. so, keep a eye on the underside during the pour, just in case.

The lower pic was one pour. The top three pics we did more than one pour. 1st was a light thin pour to fill any voids and help seal and we removed any bubbles that came up, Then did another pour. With the second pour, we did not have to chase as many bubbles. We did a light scuff sanding between coats.

This countertop epoxy pour we did not use painters tape. Because all was sealed.

I looked at your post a couple of times and I keep wondering why you are putting on a poly before the epoxy. I think the epoxy will adhere to the wood better without the poly. Just my thoughts.

Woodendreams was correct about the tape and making sure it sticks. Or you could take the time to fill any joints and any cracks on the underside with a paste wood filler. You could even do this on the top side if there are obvious gaps in the joints using a color matched filler.
Epoxy will adhere to the poly as long as you scuff sand before the pour. I have used a Wood Sealer or poly before the pours. And without. Using a Wood Sealer or poly before a pour, you end seal most of the air bubbles under the poly. End up chasing less bubbles the work up from in the wood.

Being as I'm not a big fan of epoxy tops and have never done one I can see that what you say makes good sense.
