I've almost got this beast built and I'm starting to think about those last little things I'll need. I've looked online for T-Slot clamps but it looks like all of the ones out there have bolts and T-Nuts that are to large for the V-Slot channels. Any suggestions, or do I need to go to the hardware store and invent something? Here's my setup.
Cut some simple 40mm blocks out of 1/4 x 3/4 bar stock. Drill recessed holes for M5 screws as shown and drill and thread a 1/4-20 hole in the center to either run a 1/4-20 bolt down into or install a projecting stud you can put a slotted clamp over and a star nut/knob on top of. Anchor into the V-slot with a double tee nut. These will be a bit of effort every time you want to move them as you'll have to loosen the M5 screws but on the upside, they'll stay put wherever you put them unlike tee bolts.
