THREADING AND FITTING

When you have finish turning the barrel, and double-checking it for straightness, it is time to turn the
shank. Set the tail stock back to 000, take the lathe dog off, and put a smaller one on the muzzle end of
the barrel. With a shim under the setscrew to keep the barrel from being marked by the setscrew. Put
the barrel back in the lathe, and turn the shank to the correct diameter.

On a 98 Mauser, which we will thread to, take only a light clean up pass. This is assuming that you made
your barrel out of 1 1/8 inch stock. It would be best if you have an old 98 Mauser barrel handy to look at,
while you are doing this.

If you look at the chart for threading the 98 Mauser, See chapter on barrel thread dimensions, The O.D.
of the shank is 1.100. That only leaves less than .020 for the shoulder.

This is OK as on the 98 Mauser we seat the barrel on the inside ring.
