I notice that Hemingway are now showing a Mk3 version of the Quorn tool and cutter grinder. It is claimed to be easier to set up for grinding and easier to build. Anyone taken a closer look at the Mk3?

... and here's what I found: Quorn - The Mk3 Advantage!
Much of which looks like very sensible product development [*]
[*] ... one statement is sure to prompt some debate though !!
Hardened and ground ER extension chucks and collets, readily and cheaply available, are used to retain both cylindrical and rectangular items with great precision.

Plus £61 for the detailed build instructions.

As a long term user I was interested in this.
The motor seems new ie not the Parvalux which used to be supplied. I couldn't see anything about speed control which seems a shame.
I would like to see more information on the website before buying the £61 "card".

Now using ER collets - that will upset some!
" Frankly, if you've been thinking about building a Quorn for your own workshop - you've done particularly well to wait until now! "
Mind you Hemmingway have had those patterns for almost as long as some people have had their castings...

.... especially the "readily and cheaply available" variety thereof.

Nothing new about using ER type collets on a Quorn, been doing it for years with an Emco ER25 collet chuck fitted to an MT2 arbor and another with a 1" shank that fits direct to the head.
Interesting to know some simpler method of setting is available, perhaps someone will share the secret.

I've got a second-hand set of Quorn castings seasoning on the shelf. One new addition I've made to the set is a set of Martin Models 5C tool holder and spiralling head and tailstock castings with a 2 1/2" height, instead of the standard 2" height. Since I've got a pretty full set of Imperial and metric 5C collets, with square and hex as-needed, I felt that this would be a good modification.
Even with shipping from the USA, the price was reasonable.
Still got to get around to making it though...
