Thanks to the set-up pic, you've provided the clue - it's a travelling steady. Clever design for its simplicity.

It is a bit of an unusual travelling steady as it is bolted to the crosslide. To make it work, one would need to put the cut on with the topslide.


Perhaps it is intended as a 'follower rest'

[similar function to the 'box tool' on a capstan lathe]



Edit: Here's a baby version for the Sherline lathe:

I had a look at the Sherline thing. I think it attaches to the saddle rather than the cross slide. I think the bit on the cross slide is free to move as the slide is traversed - it just adds some downward pressure to keep the steady from flexing. I guess its convoluted design means that the Sherline also lacks any part of the saddle sticking out from the edge of the cross slide.

I'll look up the box tool thing.

Oops ... so it would appear

Bad choice of example on my part blush

Thanks Micheal - most informative.

Having used a Cowells and for the past 12 months, cuts in a single pass are a bit of an alien concept to me. Still a lovely lathe though and it lives in the house so definitely preferable to getting drenched on the way to the shed tonight.

Regards, Andy

> Potts milling attachment

Having looked at the page on these, I suspect mine is 'inspired by' rather than from Potts. Mine has a 1MT taper to take the tool and generally seems lower grade than the Potts products as well as lacking any sort of maker's identification. I need to figure out some sort of practical power source and drive arrangement for this.

Potts used to sell castings so they can vary greatly in the detail, that looks like original castings.

I made this one about 16 years ago, must try using it some time...

I think that definitely answers that question then. Looks like my hunch about (at least some of) these being 'projects' was correct.

Yours is even pretty much the same colour so it's got to be right.

Thanks Neil.
