Been a while since my last post, but have been busy at work and with the Mechmate. I have been making a good bit of money with the Mechmate on the side. Have installed a set of T-track which is cheap and durable. It is Unistrut which electricians use to attach conduit. I first resurfaced the top and then cut dados into it. The Unistrut is held down with elevator bolts. The ones used were 3/8" x 1-1/4" with the sides cut off to make them easier to insert into the rail. I decided against using the Unistrut nuts with the springs as my clamp nuts and made my own by cutting squares of 1/4" plate to slide into the unistrut. These were drilled and taped for 3/8 all thread rod. I used a nut on top to secure the all thread rod to the 1/4" plate so that the all thread would be flush with the bottom of the 1/4" plate. Right now I am using the clamps from my milling machine but will make some of wood or other material in case of the router bit stricks them. Any suggestions on what to use? If anyone uses this, note that the Unistrut is rounded on the bottom, probably from the stamping process of the holes. I made a jig to hold the sides parallel and hit the bottom in the solid area between the holes with a hammer. It dosen't take much force and this will make the Unistrut sit flat and not rock. (don't try to flatten the bottom with out the jig because the sides will flare out).

There are some hold downs on the forum made from plastics that would work. You could use Derlin, HDMU or Nylon. Great idea. You may want to make the MDF "lanes' deeper to allow a spoil surface. You will loose another inch, but it will save a bit.

Unistrut as hold downs is brilliant.
