I'm working my way through a box of bits, hopefully I will have an ornamental lathe when finished. I want to finish the brass with a curling affect. I had a writeup on how to do it but its disapeared. Anyone got a writeup?

I also have this bit which has some major pitting, I'm inclined to surface grind it and re scribe the lines

Mark,

I urge you to reach out to Arthur Kingdon at the Society of Ornamental Turners which is based in the U.K. There are many members there who should be able to assist you with this equipment.

As for the curling effect, Frank Dorion documented the whole process. He wrote an article about it for the November 2023 edition of the OTI Newsletter. All the back editions of the OTI Newsletters are available to OTI Members at the OTI website.

Kind regards,
Rich

Wonderful information. I've read of such things but looked into details of the mechanisms or use. Looks like a potentially bottomless rabbit hole with a strong gravitational attraction! I need to run away - I can see myself locked in my little machine shop for months...
