An even better idea is probably the stainless steel version from Allan Burgess Engineering at 18 Bath Street, Christchurch (P.O Box 7310, Sydenham, Christchurch 1) Ph 0064 3 666 6172, Fax 0064 3 662 747. NZD 80 when priced in 2002. They have 13mm hex in the base of the pin, so it can be removed through the hole with ease. Apparently they have a much longer service life than the factory version.
Disclaimer - I haven't actually used one of these.
I've got a lot of projects going, but this would be a fun lathe
project... Ah, who am I kidding. I'll never get to it. The used
pivot only has to last until spring or summer when I replace the current
gearbox with a refreshed/lightened spare.
