Mary’s much-improved / -repaired Sears Sewing Table wanted to move around on the wood floor in the Sewing Room, so I captured its casters in little pads:
A layer of 1 mm cork with PSA adhesive provides griptivity against the floor, a solid layer of 3 mm plywood spreads the wheel force over the cork, and a top ring of 3 mm plywood captures the wheel.
Which looked like this during gluing:
The scrap on the left served to align cork & plywood; it came from the plywood contributing the shapes. The ring around the cork is a glued-up pair of plywood rings (4 mm wide, outset from the perimeter of the pads) serving to align the two plywood layers.
Verily: time spent making a fixture is never wasted!
And having a laser cutter makes fixtures trivially easy, at least for simple fixtures like those.

I need to come up with a weather-proof version for our gas grill. The new paver-type patio is was built with approximate flatness and slightly variable pitch, so I think I’ll need three pads to achieve a level grill that stays put. Cedar shims as part of the build sound appropriate…
I bought a(nother) pack of ordinary wood wedges, because they’re invaluable for measuring “how much shim do I need” in places like that.
Bonus: Mary’s long-arm machine sports an astonishing number of shims aligning all twelve feet of its tabletop. Gotta do better than that, but we’re waiting for it to settle while she gets used to it.
