Hi all
I need a bit of help
I am looking to make an arbour to mount a Parker 51 Aerometric barrel on to aid polishing.
I understand the tread is a multi start, but does anyone know what the correct size is, Thread Diameter, Pitch etc.
I did buy one from the well known Argentinian but what I received was a butchered joke, with most of the treads missing, not impressed given what he charges
Thanks in advance for any help with this
Paul
