Power feeds for Chinese mills

Actually I think I should have fitted the grub screws to the outer bearing as I look at the photo again!

Ouch!

I too am of the ability to press the wrong button at the wrong time. I was especially good at driving an overhead crane in the wrong direction, you would have thought someone was deliberately mixing the buttons up.

Now in later life, I appreciate the principles of electrical control and know that I might need some sort of switching interlock so that only one axis moves at a time, which reduces the chance of an accidental motion, also the principles of ergonomics and putting a control in a suitable place.

All this is very good in hindsight, as I was saying to my brother-in-law when showing him my 1942 lathe, loosing a finger or two is a learning opportunity.

… my 1942 lathe, loosing a finger or two is a learning opportunity. ….

Hobby lathes of the (later) 1940s mostly had interlocks to avoid long and cross travels at the same time? I would think that many, before then would, too.

Designed-in mechanical interlocks are often not so easy to ‘dis-arm’ by users, than electrical ones, is my thought on the matter.

 Ouch! @Roger Best, that cheered me up, thanks!

Yes, I must clarify.

The South Bend does actually have only one lever for cross and long feed, so you cannot do both at once.

The conversation was in the context of the ability to drive into the rotating chuck and the general lack of guarding. There is no mechanical knock-off clutch, that I know of.

Ample opportunity for accidents you only do once.

Sorry for the delay - been sick and busy, bad combination.
