Best configuration for a Hobby CNC

[JasonBModerator @jasonb]

From what I have seen once you have the spindle and the solenoid valves it is not that much more work to add a proper rack and program the machine to auto change, some of the spindles are available with tool holders ready to go to the next step. Though looking at the holders I can't see why you would not cut your own while once the basic machine is up and running as they don't look anything special. As you say unles sthere is one person looking after several machines it's not really needed if you are in the workshop on your own and can soon go over to the machine and change the tool.

He did seem to get more material being removed on the travel back to the start of the cut as the cuts got heavier which may be tool deflection or probably column flexing where it joins the base but as most of these clearing cuts are followed by a slower feed rate finish pass should not be a problem.

Only thing I did not like was him feeling the finished cut before the tool had stopped rotating!

Distractions cause accidents. Absent-mindedly feeling a whirling job for sharp edges is typical, bet he doesn't do it normally.

Making a video whilst demonstrating a milling machine would completely trash my concentration. A visit from the cat unsettles me!

The saving grace that is was not your hand, nor mine.

Yes I thought that, after 50 years machining I have still got all my digits & eyes but mangled a few suds brushes in my time. I've now brought a powered mitre saw for DIY projects, another piece of kit to respect at all times!!!!
