big budget cnc

Anyway getting back on track with your build. I would start with the design of router bed first and then decide what you need to stand it on. Or build it all in one piece. In my opinion 50x50x3 is not strong enough for what you are trying to achieve

2 years ago I had to build a punching machine (Hydraulic) for plastic I built it from 3mm box section AND it's not strong enough I have to run it about 1/4 the speed I built it to run to get decent results and I'm punching Polyprop. Any faster and the holes are not accurate! I heat the punchs to 230c as well to reduce stresses using nozzle heaters from injection moulding machines.

I would think a minimum of 7mm would be needed if I wanted to make a steel router.

I was shocked the stresses of punching plastic the aluminium casting we made wasn't strong enough to resist the forces and we had to recast in steel and on the first attempt the steel shrunk too much so we had to recast and grind to fit.

If I had a cnc machine then would have been a lot more fun lol.
