Advice on thumbnail shrinking dies

[bherman]

I recently purchased a Libert nibbler that I am in the process of rebuilding/modifying to accept different types of die set-ups. My first question relates to the size and type of die shank preferred. Is there a common size or standard shank for a small reciprocating machine?

Secondly I would like to purchase a set of shrinking dies. Anyone out there with purchased thumbnail dies that they feel work very well? Normal materials would be 18-19 ga. steel and .0625 aluminum.

I like Clay Cooks. I had a set on a P-3

Just received another set for a P-7

Brian, I also purchased a set of Clay Cooks for my P6. Beautiful things and shrink with little to no marking. Not cheap.
