Easy T-Track Idea

For those that already have an array of holes with t-nuts in them on their MDF bed you can make a few strips like shown in the attached photo and screw then down to have t-slots. Cut them so there is a 5/16" gap between each top edge when installed, and a 3/16" wide rabbet on the bottom edge for the t-bolt. You can use them alone or slip sections of real t-track between them like I have if you make the rabbet tall enough to fit the track height. I use 1/4-20 nylon screws to hold the MDF strips down. Their heads are recessed roughly 1/4" into the 3/4" MDF. Nylon so that in case you hit one with a running bit it won't hurt the bit. Start with a narrow 1/2 strip on the outside edges of your table so the back end of a clamp will have something to rest on when using the first t-slot. You won't need a screw in every threaded insert. I'd use every 3rd one.

My original CNC shark came with an MDF slot that had t-slots pre-cut in it. I never had a clamp pull through.
