Well to do an external thread you need to....

1. 1/2" UNF Die ( not a tap(internal thread)
2. Find someone with a Lathe that can do single point threading!(Best Option)

There you go... if Came with a gear switch setup..you are Ready to Start Cutting some Threads..
On your lathe,or in the manual..there should be a chart giving your which gears in what location
is needed for the thread pitch you want!!

Good Luck!

The issue might now be holding that in the jaws  ???

You may have to make another & thread it, before you mill away the flats.  ???

If you're unsure, take it to Dave at Staffs Custom Rifles. He won't rip you off.

That's the bottle pip. Dr Bob sells upgraded ones, go onto his website and ring him. If you can't fit it, bring it to me in Crewe. Get the barrel to Dave at SCR, he does a brilliant job.

On that bottle pip it probably only needs the lightest skim on that front step to square it off for a new sealing face.
