I’ve ordered a 7x7 sheet and an endmill for composites. I’ll post how it goes.

Thanks Bryan!

I just used a cheap 2 flute end mill that cut it pretty easily. The small hole in the middle is to hold it down, and I’m assuming that’s what they did too. Below are my notes from cutting some:

I initially cut the pucks at 1.125" diameter, and that gave me some dimensions that were up to 1.13". I measured the bore at 1.124". The pucks cut at 1.125" were a tight fit in the caliper bore, and won’t retract when the brake pressure is let off. I had to remove those and replace them with smaller pucks. I’m setting the OD in Aspire to 1.105" which is plenty small even with variations. It could potentially be closer to 1.12" if no dimensions are larger than that. I left the Aspire file at 1.11" OD and those will likely work very well. I fixed the others I had cut I believe, so I have plenty already. Test fit all pucks to make sure they move freely in the bore!

Very cool Rusty and thanks! What machine did you use to make them? We have the Bridgeport and a little CNC router.

I just used a CNC router for the pucks.
