While I await the arrival of my replacement oil line and nut from the factory, I am continuing my inspection of the PM-935. Today I checked the runout of the spindle.
PM-935 Runout, spindle taper (0.0002"):

Thanks David. Your documentation of this machine has been so helpful.

I inspected the table for flatness with a 4 foot and a 2 foot Starrett straightedge and a 0.0015" feeler gauge. The feeler was a No-Go (Good) all over.

I checked the table for twist with the machinist level. No twist was detected. (Machine is on pallet and not level)

The nameplate had white paint overspray so I peeled off the plastic film and sprayed it with clear acrylic paint. The film was not the 'removable' kind. I had to use alcohol and a plastic scraper to remove it.

I powered up the mill for the first time and ran it through the range in High and Low gear. It sounds normal.

Very nice. You got my curiosity up and I went and measured my runout on my 1054TV. .0001.
I am a follower of Abom79 on youtube and he just recently got a KBC Mill and used some CRC Belt Conditioner on it. Made it quieter. So i tried it and sure'nuff, it got a lot quieter.

I need to get a 0.0001 indicator to get a more accurate reading. That is a 0.0005.

I got the table off and the oil lines exposed. The damaged line goes down into the saddle under the leadscrew nut housing. I am hesitant to remove the housing because I don't know how I would get it correctly aligned for replacement. P.M. parts dept is going to contact the factory for guidance.

TABLE LEADSCREW COMPONENTS
Leadscrew bearing bracket dowel pins are not present nor are the holes for them. I don't know about the leadscrew nut housing dowel pin. I'm hesitant to remove it until I hear back from P.M.
