Hi,

Trying to figure out are these Harrison splines their own "standard" or fits to some international standards as well? I'm not strong in mechanical theory, from what I found, ISO 14:1982, for example, defines smallest sizes d=11, D=14. But Harrison splines have D=11.

I need to order new leadscrew (and also make new female part) and I thought that it would be good idea to use closest standard dimensions if existing Harrison are not standard. Or they are standard?
