First things first. I built a table to serve as a launch pad for my JGRO build. The table measures 36" x 48" x 22". In retrospect, the table is too small. I'd make it at least 42" x 60" x 22" if I did it over. I'd also make it a four poster (like a bed) so that it would be easier to build an enclosure around it for future dust containment. Table materials are 2" x 2"s, 3/4" plywood, with eight RTC22 corner brackets and SD8X1.25 Strong-Drive Screws made by
Simpson StrongTie and purchased at Home Depot. The plywood is fastened to the 2 by 2's using 1 1/2" finish nails.
If needed, extra bracing can be added at a later date.
