Been working on this little project last few weeks. I see the cheap plywood mill to make a better machine frm 12mm acrylic (plexiglass)
It's really strong stuff and machines easily . I have started to prototype in acrylic as it is quite cheap vs metal. 1x2feet 12mm thick os around 15 dollars.
I made a lot of prototype parts for this testing and getting dimensions right. I did 3d modeling also bit sometimes the real world isn't the same.
I assembled it and noticed right away it was more quiet than the other machine. The polyethlyene spindle mount absorbed some of the vibration vs the U bolts on the other machine.
