[chbot] Recommendations for CNC'd parts

[Andrew Errington]

Does it have to be CNC?

Probably yes, when you want to make a lot of them. But for the first
one or two for prototyping could you do them by hand? Assuming you
haven't passed that stage already.

Our Men's Shed has a very good metal lathe. If you hunt around you
might find a lathe near you that you can use, and asking here is a
excellent idea- I hope you get a lot of responses.

Stainless steel is a bit hard. Can you use regular steel to start
with, and move on to stainless when you've got the final dimensions
and verified the design?

Good luck,

Andrew
