I am about to mount a 4 x 8 table on the powerstick for my Buddy. I see in prior posts that Brady Watson recommends MDO support board and high moisture resistant MDF for the spoilboard. Brady, I'll go with those if I can find them, glued together, as you recommend. (I usually screw the work to the spoilboard.) I've had a little warping with the original factory MDF table with low-quality MDF spoilboard scewed to it. (The Bot is in a woodstove heated steel quonset hut, with a lot of openings to outside air.)

My thought for the big table is 1" MDO and 3/4 MDF, but I'm concerned about the weight. Has anyone had good results with 3/4 MDO or other 3/4 ply as the support board for a 4 x 8 sheet Buddy, or is one inch the minimum?
