I wanted to make this small adaptation without having a TV-7M lathe, and even more so my NGF 110 milling machine. I also conceived it, I use the Corvette 401 lathe for cutting, in which, by the way, there is the same Morse taper 2 in the tailstock, which allows use the same tool from the TV'shki, except for the incisors.
I have thought about a thread-cutting chuck more than once, but I see the point of using it only for batches of parts. To cut a pair of ordinary threads for domestic needs, install a cartridge, select an adapter and insert a tap or lerk - it's all very long.
In the end, I decided to stop cutting exclusively by hand for now.
It is clear that the main purpose of this product is tool alignment. But for me, safety is more important, it is for her that everything is ultimately conceived. The hand is freed, which needs to provide preload with the tailstock at the moment the tool enters, and the number of quick manipulations of the hands over the machine is significantly reduced.
