Building good prototypes often requires setting up fixtures. The workshop has been growing this year; we have a new CNC Router, which helps us build accurate fixtures and components from wood, plastic, and aluminum.

In this video, we’re CNC routing part of a fixture that we’ll use to hot-form polycarbonate sheets. We fabricate this kind of thing in-house as much as we can so it’s quicker to tweak, because even this fixture could be considered a “prototype” that will probably need to be adjusted.

Update: We made good use of this fixture so here’s a follow-up video of building the next iteration. The material for both fixtures is a Poplar board, which is commonly available at the hardware store, easy to machine, and is already kiln-dried so it shouldn’t warp much in the oven.
