Started building a 2x72 belt grinder. I've got the model in FreeCad done, here's a thumbnail picture of the model:
This is composed of about 16 parts in Freecad, assembled with A2plus Assembly workbench (File belt-grinder-assembly.FCStd). I used simple rotate/translate in the assembly rather than relative constraints, I tried the constraints but changes broke to much. I may try Assembly4 for future projects. This is still a learning process. The (pink) base is set up so that it can pivot to a horizontal configuration to be used as an edge sander, the arm with the table under the platen rotates appropriately. Design includes a disc sander off the side because I could. If anyone is interested, the design files are attached, but it might be prudent to wait until I'm done to see what works/doesn't work with this design. Some of the hardware detail is missing, I didn't add all the bolts and pivot pins, etc, to the drawing, just gets to be too much detail. Also I'm doing some welding to put this together. The CAD design includes holes used as weld pockets, which I like to use as they seem a little easier to retain alignment.
