Was up to the last word and dropped the mouse and closed Windows, everything disappeared. GRR!
The top cats head was made for my old South Bend 9C lathe from a piece of scrap bronze. The set screws are standard steel with rounded ends to prevent marring the barrel or lathe spindle. A friend suggested 3 screws would work for centering. It did but it was not as easy to adjust as 4 screws in opposing pairs.  I did use this one to rethread my dad's 1917 Enfield then later rework the chamber as the fellow that did the chambering left a sharp edge on the shoulder that would catch the case necks when chambering slow.

That is a US Krag barrel in the 9C. The 9C (with a 3/4 inch through hole) could be used to shorten a barrel with the same profile down to 24 inches, when using a 4 jaw chuck. Substituting a short cats head for the chuck you could probably shorten a barrel to 22 inches.

The second is for my tool room lathe and was used in sporterizing the 35 Krag. It is made from stainless and is a precision fit on the spindle stub with no arrangement for clamping. Screws are shop made brass with flat ends. Even though the tool room spindle is longer it allows shorter barrels to be worked on because of the larger spindle ID.

No cats were harmed here. I did not name these devices, long history of use by gun smiths and they have always been known as cat heads.

Anyone have a list of which European Krags have left or right hand threads?
