Want to try Rotary Axis, possible to hack together before investing more time?

This was my idea, but it really only allows for simple 2D cutting on round stock. I finally got around to buying a crappy ALIExpress 4th axis to put it into play. I think I bought the 8PDT switches (oh, i couldn’t get them so I bought some 8PDT relays) and I might have a couple of easy drivers from my Arduino days. So, I have everything needed to cobble the monstrosity together now.
