Making some progress with my Hemingway tailstock for holder. This is the adapter piece for the 5/8" and 13/16" size dies. Going to make a 3/8" mandrel to allow me to turn the outside diameters down to final size

It's already cut, you just have to machine the end of it to fit the rest of the die holder

I assume that this is the kit for the design of J.C Payne and if so , it looks a worthy addition to anyone's lathe. Mine, I'm afraid is the old classic design which I must have made when lathes were fitted with No1 Morse taper tailstocks and since, I simply added a Mt1 to MT2.

What did come up whilst I was 'looking up' the kit was the Mark3 Quorn tool and cutter also from Hemingwaykits. I have the original Mark 1 from 1974 and noted that for other aspirants(?) there is a new reference book on the changes. The price of book etc is probably £70+- but I'm going to have one.
More anon

Yes thats the one, its the J.C.Payne design. This tool comes in MT2 or 3, this is the 2 so it fits in my small lathe tailstock and can always adapt it up for the bigger machine.

Got no pictures but I have faced all of the other bits to length
 
Hi Sam
I've got a crate of Geo Thomas/Hemingwaykits stuff and I'm sure that you will get a lot of satisfaction and use from the die holder.

It'll get a fair amount of use in work too, especially for those jobs where we have to thread stainless (which being a boat yard tends to happen fairly regularly)

I've ordered the Quorn MK3 tool and cutter grinder drawings etc.
Unearthing my long discarded Mark1 is next!

More die holder progress. Made a mandrel to turn the outer diameters. Got to within half a thou on the large diameter and the smaller one is dead on an inch. Mini lathe can do some accurate work as long as it isn't abused

A VAST number of drawings have arrived.
The first glance(s) suggest the need for comparing my old parts with the revised versions- and the need for lots of dividing and graduating.
For those who wonder what abrasive wheels are suitable to do or re-sharpen tools, this is IT
 
Not much progress to report but have set up the four jaw for machining the larger of the blanks. Don't really need a four jaw but o thought I'd get some practice in. Going to machine all the blanks to size for the threads and the boring operations and then going to do the tapering operations last so as I can keep the angle the same without disturbing too much on the machine

Bit more progress today. Screwcut the end of the larger die holder, job stopped ATM as I need to borrow a drill bit from work so I can put a 5/8 reamer through. Because im borrowing the drill and reamer I turned the outer diameter of the smaller die holder and drilled it ready for the drill/ reamer tomorrow

Borrowed a 39/64" drill from work so managed to ream both parts to 5/8". Also managed to find the time to bore out the die holder parts. Rather than use the nominal dimensions given on the drawing I bored out enough for the die to be a good fit in the holder

Of course, you could be wrong! Ideally, you should leave enough room to open up the die using the pointed middle screw. In other words being able to open the die to start thinking that you are aiming to do stainless steel, it is worth considering

Hi Norman, it's not a snug fit or anything, just a nice fit in the holder so it's easy to get in and out. this is for the 1" dies and all of the 1" dies I own are solid anyway so haven't got the split. The larger one is to the drawing which happens to be the same size as my dies
 
I saw a split Whitworth die hence the comments . So I now apologise!
Of course, you will acquire more dies- said he coughing discretely;)

I have drawers full of them- no, not the ones which I wear:oops::oops::oops:
 
Just a quick note to say great work on an interesting project.
Following with interest!
