Building my own CNC machine, for both plasma cutting and for slinging a dremel around, and after pricing ebay/used/new THK slides and competitive products, I decided to at least try making them myself.

Turned out not to be anywhere near as difficult as I thought it would be. I hope I posted this in the right place; After looking at several forum names I guess it could fit in multiple places, but I chose this one "just because"

Some bearings, some square stock, a few drill bits, and a digital caliper makes this easy work. Figured I'd share this since I see a bunch of threads about how to make such things yourself.

Step 1: Making the saddle chassis (need four of these):


Step 2: Making sure all the holes line up well enough to bolt together:


Step 3: Machine two spacers per bearing (eight bearings total per saddle). Whit the bearings I selected the two spacers need to be 0.152-0.153" for a tight fit:


Step 4: Bolt it together and hope it fits:



Step 5: Make more!
