Crown centres

Bill21:
I’ve thought several times that they would be easy enough to make. I’ve just spent an hour in the shed making one with a parallel shank to fit my chuck jaws. I feel daft ordering one now.  ::)

I can’t seem to upload a picture so maybe a link instead.

Impressive, but only possible if you have an engineering lathe and mill. Most woodturners don't have that.

Derek:
Very nice Bill21 but I feel that a grove around the shank would be beneficial to prevent the bit from being forced back into the chuck when tightening between centres. Also, did you harden and temper it to help reduce wear over time.

Bill21:
I can’t see it moving in the chuck but if it did I could cut a shoulder on it. No it’s not hardened, it’s stainless steel like the ones Axminster sell.
I’ve just finished making another one that inserts into my revolving centre. Thought I might as well whilst the mill was set up. Now to sort through my spindle wood stash to try them out!

icewoodturning:
Try RDG tools. They do small drive and revolving crown centres.
