  • Single/multiple point threading?

    I needed to thread a 17 in. piece of one inch pipe. The power threaders were all out of the shop. Well why not set up a chaser die from a power threader? Set it up in the atlas lathe using my homemade ball brg. "steady". Set the chaser in a 4way post and squared so as to keep the taper proper. Took a marking cut and it looked fine. Ran the thread about two pitches "running". Turned out a nice tapered pipe thread. I was wondering how many have tried this method?

    Woke up to an inch of snow this morning. Gone now.

    I've used dies from geometric die heads in a 4-way tool post to create long threaded sections. Just clamp one die in square to the direction of travel and engage the half nuts...
    In a couple pases you are done; works great!

      It works fine for making tapered threads and straight threads.

        Works great, leaves a great thread form.

          Been using them for years.
          Even use them for thread milling on the CNC.



          And the latest use is to fit them to the swing threading tool which I now use all the while.
