Due to the chilly weather I decided to pour the resin inside of the house. I laid down a sheet of painting plastic and a couple of blocks to raise the table top off of the floor about 4 inches. I used masking tape to go all the way around the bottom edge and used a razor blade to trim it smooth. This will hopefully help keep a smooth drip free bottom edge.
Once both pieces were cured I flipped the top onto a clean surface and removed the tape to see a nice smooth bottom edge. I centered the base and used 1/2" brass wood screws to attach the top to the base and flipped it over!
