Die holders for MT2 and MT4 lathe tailstocks
This 4 indenpendant jaws diam. 420 mm (16.1/2") chuck is a little headacke as it weighs around 65 kg (144 pounds)
A number of time I was not able to cut a thread well centered by hand. Looking into some literature, I decided to make a dye holder for the two lathes I have.
The tappers have been turned between centers
First trial without a tapper attachment which I project to make later on. The displacement has been made with a small bore head in order to avoid recentering the tailstock
Milling the slot on the MT4 tapper
13 die holders have been preturned - here the ten first ones..
