    Default Quorn Mk3 - Universal Tool & Cutter Grinder

    There's now a Mk3 version of the venerable Quorn: http://www.hemingwaykits.com/acatalo...__Grinder.html
    Earlier this week I decided to take advantage of the USD to GBP exchange rate, went ahead and ordered it.

    I saw that. I'm not sure if there were any casting changes between the Mk2 and Mk3 kits.

    I think the biggest change that Hemmingway's have made to claim a 'mk3' design was the modification of the work head and spiralling head castings to be able to use ER32 collets.

    Martin Models have been selling a 5C collet compatible set of the parts for quite a few years...

    I just looked at the Hemingway site at the MK3 grinder info.
    This came from there: • A new Differential Screw arrangement provides a feed into the wheel graduated in ten thousanths of an inch [0.0001" - 2.5Ám], allowing infintessimal amounts of material to be removed.

    Ten thousandths of an inch is .0001? Who knew?
