Over the holidays, after evaluating alternatives for cutting the acrylic and aluminum, I got a bench top band saw.
It has allowed me to make all the parts for the feeder quickly and reasonably straight. I even figured out how to make the treat ramp inside to keep them from getting stuck. I used CA glue to bond everything. That was a little learning curve. My new clamping surface plus some masking tape to avoid gluing the parts to the bench worked great. So, here is the assembled unit:
I'm very happy with how it came out. Next is installing the servos and getting it running under power. The placement is going to be tricky.
