SouthernMike,
Thanks for the reply and input.
I have been reading about the noise issue with Realtrax. It does have me concerned so here is my plan. I have a 4x8 table with 3/4" plywood as the top. I have a bunch of 1/4" rug padding that I was going to use to cover the plywood. Then I was going to use a sheet of Homasote on that. I was going to use the rug padding for the track on the elevations too. Fingers crossed.
