Could we 'ave a shufti' at this contraption mounted on your lathe?

Cheers, Tony.

I'm assuming it's for repetition work like turning out a load of studs the same length, though I have to admit I'm not really sure!

Certainly- I'll try and remember tomorrow.

P.S. Yes; 2 functions really: for repetitions like making multiple studs, for instance, and to allow the item being turned to be removed from the chuck (for measurement, for instance) and returned in the same position.

Hadn't thought of that, something I would have found useful a number of times.

I'll add it to the list of things to make (which also has a spindle handle a la Wolseley Phill on it) - don't hold your breath!

Great work Martin, I wouldn't mind being able to make one to that standard and in as little as four hours myself!

Phill.

In answer to Tony, above;



This is what it looks like fitted. The two knurled wheels are turned in opposite directions and lock into the spindle tail-end solidly.



...and this with the gear case closed as it would normally be.



This is the nose with the depth stop extended to reach into a chuck, and the taper plug fitted in the nose to keep it centred. With longer work pieces that reach into the spindle there's no need for the plug, and there is a shorter rod instead of the long one.

Many many thanks for that picture, it explains everything. Now how many times have I wanted to make more than one stud! I normally just bodge a three cornered packing piece and slot that between the jaws.

Any chance of a line drawing or the spec? ? ?

Cheers, Tony.

Actually Tony, it started with a drawing from Model Engineer's "Workshop Practice Series, 39" - "Model Engineers' Workshop Projects".

Then I made it up as I went along, to suit my lathe, as none of the drawing were suitable (I think it was intended for a Myford). It's all very simple and logical, and I think you could make it by looking at my pictures and choosing dimensions to suit your machine.

Thanks for posting the "in situ" pics, even I understand how it works now

I forgot to finish this little project...



There we go, and now put away in the cupboard with all the other odd shaped wooden boxes!
