has anyone threaded a 7mm nose cone? i tried to thread one with a 1/4-28 die which did not work. maybe i did not go slow enough. i have some schmidt a3 refills on order which are cross size but with a small collar to use a spring. would like to use a ready made 7mm nose cone that i could thread with taps and dies. try to make a slim click pen with that refill and a schmidt shm192 click mech. i might have to make it where the click mech comes apart on top, but would rather have the nose cone unthread. any help or input would be great.
