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.

No that's not what I meant. The 3" chuck irving has is good, but the 4" one he linked to would be too big - so buy his 3" chuck asap as that's a very good price and work out how to make the backplate! It's easy to make a chuck key...

Round one end off with it between centers then use that end to hold it in the chuck as normal? Unless you need to machine the whole length in one pass that should work...
