    The alignment with pillow block is correct now, good. And everything rotates freely, which is good.
    As to noise at higher RPMs - do you hear it only in Low gear or High gear or both?

    Pics would help. I only threaded as fast as 32 tpi on a 7x8 mini, but never had issues.
    Changing gears was a breeze and adjustment to those 2 nuts did not pose a problem

    Held a bar in the chuk and ran dial indicator along the bed. There is about .005 variance along 6" travel.

    Are the min/max values you provided for 3B fit?

    Thank you!

    Richard:

    Would that be the OD of the shaft's or the hole's threads?

    The shaft's manufacturer is telling me the shafts in their production area miking to 1.175, he's not sure about tolerances...

    Can't test hardness.
    Should I be able to use HSS tool, or do I need carbide/TIN?

    Do I need to anneal the 4130 rods?

    This is the first time I will be turning 4130 rods on a lathe. Can I turn them as is or is annealing required?

    I understand that part, but the tools do not produce holes with ID equal to their OD.
    1/2" drill bit produces something along the lines of at least 17/32" hole, thus the question. Similarly 17/32...

    I was just told to subtract thread pitch from the diameter: 19/32 - 1/32 - 1/32 = 17/32
