Homebrew tool and cutter grinder open source
I'm thinking 25mm SHS arc welded frame,
Worm drives from a car wiper motor,
500w grass trimmer spindle,
er11 to 25 say workholding,
nema 17 or 23 steppers,
24v psu, toshiba drives.
It would have to be 4 axis to do a helix, or 5 axis for a ball nose cutter with relief.
No bigger than a shoebox, maybe welding isn't even required.
I'm sure there would be lots of interest given most people here would already have all this stuff from early experimentation.
Thoughts? Interest?
Wisdom results from foolishness!
