Thor, or should that be Zeus?

[Neale]

Has anyone tried one of these, looking for an attachment that I can use to grind on Thor.

Chaz - that looks suspiciously like a ready-built grinding spindle for the Quorn tool and cutter grinder. This was a design from 1974, sold as a kit of castings and hard-to-get materials. Quite a lot of kits have been sold, and some of them actually built! From that point of view, it's a tried and tested design with nothing exotic about it. The original used labyrinth seals (a series of fine grooves) rather than the lip seals in the advert but maybe materials have improved in the last 40 years By all accounts, they work very well for fine grinding and people use them as toolpost grinders in lathes. Light duty, though - not for heavy-duty work. Plenty of references to the Quorn via Google. I have a set of castings under the bench that have been maturing for the last 30 years or so - come back in 10 years and I'll tell you how it works from personal experience...
