Have you made something for fixturing on your XR?

I am looking at cutting holes in 120 pieces of 4’ long C-channel and have 120 more at 30".

Have any of you made a fixture that you can position parts repeatedly and change when need?
I am looking to do this but would I always like to see other peoples ideas.
No need to go into great detail just some pics to start.


I haven’t done it, but I would build a frame on the table. to load a consistent number for your 30 inchers you could be able to load the frame three rows tall. And whatever the math works out width wise make that how wide you make the frame. Then it’s simply creating a ~45x90 inch cut pattern in your cad program.
