12:05 Garage- ’70 Duster build

racerjoe said

Here’s the drawing. Since I don’t know how precise the laser cutter will be, I had the holes cut smaller than needed so I can drill them to a true 1/2”. I ordered them this morning from sendcutsend.com. They were only $14/ea. And had free shipping. All the local shops had a minimum order so I was forced to use an online resource. Oshcut.com was considerably more expensive per part, setup fee, and charged for shipping.
I guess I need to order all the other parts to get this done. Turning out to be much easier than anticipated.

What material did you get these cut from? SendCutSend doesn't seem to have a very broad range of materials.

I shot myself in the foot with my layouts. I had the hub face further away from the spindle than it was in reality. So my 1/2" or 3/8" adapter plate on the front of the spindle turned into less than a 1/4" plate once I cut down another rotor and put it on a spindle so I could get some actual measurements. So now the adapter has to go on the backside of the spindle and I need more than an 1" of spacers to get the caliper in the correct location.

The other option is a GT500 rotor with the SP caliper. That one would use better than an 11/16" plate thickness, but SendCutSend seems to top out at 1/2" for the milder stuff and only 1/4" for 4130. And the smaller GT500 rotor seems to make getting it to all fit a little tougher.

I guess if it was easy, everyone would do it.
