That made me think of using this as a template for what would be essentially a sacrificial board. Piece of plywood the dimensions of the table, drill some evenly spaced holes, make a clamp board supporting various sizes.
Today I tested a 1/4 piece. I used the Incra clamp, eats about 1/2 inch of the edge, two mirror hangers at the top to hold it in place and at 0 and another piece of wood clamped across the bottom with just the supplied clamp. And the supplied clamps. Possibly overly secured. I ran a simple image fast and at .80 and everything held up just fine. Next I'll spring for some acrylic. I think the Incra is a bit too large. I'll wind up cutting some small pieces of wood and using the Incra knob set to make something smaller. The window clamps I used wingnuts on, and may work in that direction so as to limit the size of the clamp.

All this talk about mirror clamps reminded me of the mirror cutting bits I saw on toolstoday.com I also have a 3/4 plywood part I will use as sacrificial bottom but keep an eye on warp, I may use those carriage bolts to make sure the plywood is flat on the deck.
I realize that this is an old topic, but I was wondering if those who had bought the Incra clamp a while back found them to be worth the effort? At only $10 each on Amazon they look like they would be better clamps than what came with the 1013.
I cheaped out, went to lowes and got some 2" long 1/4" bolts square nuts to fit the track and fender washers. I put a nut on first then the fender washer, and bottom square nut for the track. I tighten the bolt nut in the track and then crank the top nut above the fender washer down to the material, works great and didn't cost me 40 bucks.
Addendum: I place a scrap piece that is comparable thickness of wood I'm carving on other side of the fender washer to hold it level.
