4 jaw chuck Boxford - Axminster etc

[Fivetide]

Yes its hard turning square stuff in a 3-jaw.

What size chuck are you looking for, think a C1 is limited to 80mm

I might still have a old 3" one that you'd have to make a backplate for, and find a chuck key to fit... its worn (its probably c1930) but usuable. If I still have it its your for £20 +P&P

Theres one here: BURNERD 4" 3 JAW LATHE CHUCK FITTED BOXFORD BACKPLATE | eBay

But a new one is only £50...

Thanks for the offer irving, but if Jonathan thinks it would be to much for the lathe then I'll take his advice.

I remember John S told be in no uncertain terms that a 4" chuck is too much for the C1 lathe, so your 3" chuck sounds like the best bet. I'm currently loooking for an 80mm 3 or 4 jaw self centring chuck for mine since the one I have didn't come with the external jaws, which is exceptionally annoying.

Could you hold it between centres?

I do hold it netween centers but its not always inline I tried the method may Dad suggest , marking the center holding againt the point then tighting the chuck it works to some extent but sometimes it out and the vibrations not doing the Lathe anygood I think. They are to thick to fit through the chuck so I can round one end off.
