Interesting Mill Design on Hackaday

Saw this posted on Hackaday, thought it worth mentioning here...

Self Replicating Milling Machine

Not sure I'm qualified to have any sort of opinion but workpiece access is a bit restricted, and I can imagine any flex or vibration having odd effects due to the structure.

If using the X2 mill head and column why not use the whole thing? I don't like the idea of using the rack and pinion for the Z. It must give no end of problems with the backlash.

Looking back at this and reading the blog -

"This chatter eventually became so serious that some screws which I had failed to tighten fully began to back themselves out."

:-O

I don't get the "self replicate" bit. Not the spindle - not the slides nor the carriages. Not the racks - not the screws - not even the square bar - not the sweet FA apart from maybe the odd bracket.:confusion:

Hey,
He'll have a great degree by now and will be telling mere mortals to make parts with a 2mm blind hole at right angles at the bottom of a 100mm deeep 4mm hole ;-)
