If the countershaft is bent, even a little, it will cause a LOT of vibration.? Rough handling during a move can bend the countershaft or the big pulley on it.? That is a common problem. Jon

You may have motor issues. Check that first. If not you can go to a heating supplier they have pads for furnaces, you can set your lathe on them and bolt thru them? GP

i hadnt good idea.... as you can visibly see the mounting plate bouncing up and down

Likely not much difference. Have you considered shock mounting the motor? -- *I Love Anything That Turns Money Into Noise*

Are the vertical versions more susceptible to vibration than the horizontal types.

As Bill said the lathe came with minimal tooling, I think a faceplate and centers. Everything else was extra, so some bought Atlas (or Craftsman) tooling as that was easy, and could be supplied with

My 1950s (per registry sn estimate) TH42 came 2nd (or more hand) with a 5” BB 435 Atlas 3 jaw chuck dated 6-51. May or may not be the original chuck? Don’t know if this helps. I recently picked

My 1946 TH42 came with an Atlas 5" 3-jaw chuck, IIRC. It's FUBAR, and awaiting time for me to try out one of my tool post grinders on it... If it's a real Pratt it should be a very good quality chuck,

just heard back from pratt burnerd apparently the chuck was made in december 1949!!

This is a Pratt Burnerd chuck. It was good in it's day. Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ Sent: Wednesday, March 12, 2025 8:13:06 AM To:

I am replacing the spindle belts on my Commercial 12". This is on a cabinet so the under drive option is used. I have pulled the spindle, but the back gears need to come out as well and I cannot

Cdcotools.com seems to be a go-to place for a lot of people due to their good customer service department. I bought original my OXA set from them, and afterwards, I picked up tool holders from ebay,

thanks for that.? I was trying to measure from the compound to the chuck center it wasnt very successful. ? The company people seem to rave about here said on their website that the tool height was

I'm not sure anyone answered your question.? But FWIW, using calipers on my QC42, I measured a distance of 30.9mm (1.217") between the spindle centerline and the mounting surface of the compound. In

Doesn't really matter, it's not a precision machined part to begin with and it's just a pivot for the belt tension so nothing to worry about

the hinge pin doesnt turn.? it just allows the hanger to rise up and down on the cam for tightening and slackening the belts

May want to check the bushings at each end of the hinge pin, and the pin itself. Might need to replace one or more of them. Do you have access to a surface plate? If so that would help you check the
