JGRO Build - Some Assembly Required
After being overwhelmed by all of the different DIY CNC table builds, feature advantages/disadvantages, functions, sizes, etc. I decided to go with a proven winner. Special thanks and a deep bow to JGRO for graciously sharing his table design FREE for the CNC hobbyist.
I decided to go with an almost stock version of the JGRO table and started printing out the plans and acquiring materials over a year ago (Jan. 8, 2005). Today, after much agonizing, sweat, sunburn, blood sacrifices, and late nights, my table is nearly complete. Items to finish include cable beautification, home & limit switches, RotoZip mounting brackets, an enclosure to contain dust, and tweaking.
I'm under no delusions that the end result is perfect. The table could be flatter, it's a little out of square and there is an extra brace for the X-axis roller bearings. It doesn't matter, as it still seems to be more accurate than any drilling and sawing that I can do by hand.
After a request from Jason Marsha, I have decided to document my build in this thread. I'll try to note minor changes I'd make if I had to do it all over.
Off we go,
HayTay

Launch Pad for JGRO Table
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.
