Good Morning,
Rookie here.
I have no Mechanical Engineering education, but a little practical skill.
I have recently acquired an old (1933) Walker-Turner lathe, and need to determine the spindle thread size in order to obtain an adapter to a more standard thread. I am pretty sure the spindle is 1/2-inch diameter. Couple questions:
1. What is the easiest way to determine the thread size (I tried purchasing 1/2-inch, fine threaded bolt, but no go)?
2. Research says that 1/2-inch taps are available in TPI's of 24, 27, and 28. Are bolts or nuts also available in these? I would prefer to purchase a bolt or nut to verify the thread before moving on.
3. I am considering transitioning to a 1"-8 TPI spindle by obtaining a 1"-8TPI Bolt and having the hex head drilled and tapped to match the existing spindle geometry. Thoughts? Is this something that can be done on a drill press, or is a metal lathe required?
Thanks a lot for pandering to the rookie. I am sure more questions will arise in my journey.
Thanks and have a great weekend,
Greg
