New PM 932M-PDF arrival

there is a radial bearing, upper and lower races and 2 nuts on the bottom of the leadscrew. the nuts were so loose there was no contact of the bearing with the upper race. I believe the nuts and bearing would have quickly fallen off from the screw turning and vibration. the bottom nut (lock nut) was almost off.

there is a bolt and washer that holds the worm gear on the hand crank shaft. this is how I found it. I screwed it in about 1/4 in and snugged it with an allen wrench.

the inside of the column was actually pretty clean. there was some grit sitting on the corner gussets but not a lot. cleaned it up, removed the animal fat they used for grease (kidding) and re-greased with Belray. put some oil on the leadscrew.

this is what happens when you put body filler where a large bolt has to be tightened.

rented an engine hoist to set the machine on the base. learned that the higher you lift the more the machine tilts (duh). used a 2nd strap to start out tilted and make it level by the time it cleared the base. went well for a one man show. still have to do the final wipe down cleaning, test electrical, install the X and Z motors and then on to checking things out and tramming. going to take my time.

I do shake my head at the body filler. To me, the only purpose of the paint is to prevent rust. I would be happier with just paint and to have imperfections visible in case they start to become an issue

I'm guessing that their (the chinese, not singling out PM) castings are pretty horrible and we would not purchase the product if we saw what it actually looks like. there were a few very large voids they slapped putty on INSIDE the column, almost looked like they could go all the way through to the outside. maybe they do. if they need to putty it would be nice if they would use something a little more durable. and as I'm sure that PM reads these threads, Matt, please supply some touch up paint with the machines

You guys are killing me. With my luck, I’m going to get a crate full of loose parts.

hopefully not but you need to check. need to go into the column anyway. just hoping the head is ok. not up to dismantling the gearbox to check at the moment.

completed the final cleaning. the citrus degreaser worked great on the painted surfaces. installed a plug for my 220 receps, powered up and all controls working. after electrical check I installed the X and Z axis motors and tested all mechanical functions. everything is working.
