I just finished up my Hemingway die holder. It incorporates a double cone to engage / release the die (pushing the handle on the fork towards the head or tail stock presses the middle female cones to engage with the male outer cones, engaging the die - releasing the handle disengages the die letting it spin freely). The drawings and build notes were clear and very straight forward. It was a fun, relatively quick little project. I wonder if the added complexity of the clutch mechanism really yields much benefit, but I’m looking forward to using it. It’ll hold 4 different O.D. dies, starting at 1/2” and going up from there.

Very cute!
I accomplish the same thing by holding and releasing the die holder, which always spins free on its shaft. If I can't hold it, the thread should be single-pointed anyway.
 
I made this kit awhile ago, and have used it quite a bit. It's very effective, quick to use and to change dies. One issue I had is in initially assembling the pieces, I screwed the thing together a bit too much, and it made it so the clutch would not readily release when relaxing pressure on the handle. This is a big problem and ultimately cutting a 1/2-13 thread it jammed up, spinning with the chuck and breaking the handle off when it hit the cross slide.

So I fixed the handle and reassembled (with thread locking goop) a bit looser, and polished up some of the parts a bit. It works much better now and I use it pretty frequently.

I also have a Geometric die head and that also works great. Overall, while they overlap a lot, I use the Geometric for larger threads, because the force one needs to apply to keep the clutch from slipping can get a bit high with the Hemingway.
 
I sure would like to try this kit but I just cannot bring myself to paying $60 for shipping and I cannot find just the prints to make it. By the time I spent the money for the kit, shipping and time I could easily purchase something. Interested in how it works though??

I have purchased plans from Hemingway for a number of their items and bought materials to avoid excess shipping.
 
The material supplied in the kit is easily obtained locally. Possibly except for the machinable MT3 piece, but that too could be fabricated pretty easily. In fact, when my shipment arrived (and I don't recall it was $60 for shipping, seems like it was less) most of the heavy pieces had fallen out of the box, so I replaced them from my inventory.
 
I am in the US. I would love to purchase just the prints and if that is available on their website I sure don't see it.

Send me a PM. I bought two full kits, so I have two set of prints. You can have one.
