The unimat is a very under estimated machine.
Jan Gunnersson engines, especially the V4 oscillator, well within its capabilities.
Bolted down to a decent 50mm thick baseboard - all the rigidity you need.
I have two unimat 3 on a board back to back, one for drilling and very light milling, one for lathework.
Top whack you can just skim 75mm tube.
Enjoy.
