    I took off the tool mount and cross carriage. The carriage came off easily. I think it was the added weight, plus I may have had the engine lift slightly too taught, so as I slid the carriage off, if the engine lift didn't move equally the tension on the straps would increase.

    No damage to the Teflon or bed

    You have it correct, to inspect repair and rebuild. I am going to paint them factory gray...trying to decide on the paint type now.

    To do a proper inspection and rebuild. Plus a proper paint job back to factory color. I don't like it when machines are painted when assembled, it's hard to remove all of the grease and other stuff from the crevices. Plus, when you paint it assembled all of the joints are filled with paint.

    I have 4 metal lathes, I can do without these two for a month.

    Took a few days off, but back on it. Got the bed off of one of them this morning. Looks like the factory color was green, for sure switching it to a factory gray!

    Tomorrow the beds will be removed and degreased with purple and a pressure washer.

    Having issues getting the drain pipe off. I thought about heating it with a heat gun or torch, not sure if any excess oil inside would smolder/catch fire. Any suggestions???

    Pastel colors including Green, Yellow, Red. And white (my favorite), and possibly black.
    Even saw a light red-pink one once. Wish there were cell phones with cameras back then so I could have a couple pics to share.

    Got them off. Used a tiny bit of heat and a lot of leverage.

    Next step is to degrease and pressure wash the pans.

    Beds are off!

    Glad I took them off, now I can do a proper cleaning of the top and insides...a lot of gunk in there after 40 years!

    I spent and hour sanding and stripping with very little success. I decided to send the beds and control covers out to be blasted to remove the paint.

    I noticed that they have different motors.

    Spent the last few days cleaning the first lathe inside and out. I wanted to get it clean prior to sanding, that way oil and grease wouldn't get onto the freshly prepped surface.

    A lot of time with 50/50 purple/water, then a follow-up with simple green.

    I decided to lift the motor so that I could clean under the motor mount as well

    It's been a while since I have updated, but the progress is ongoing!

    I got the beds back from the blaster and they looked great, saved me a LOT of time and materials. I did not have them blast the underside as the paint was good. I am sanding the underside edge about 4" in so that I can get good primer/paint adhesion. This area is a little visible from underneath and I wanted it to match.

    The welded corners were no longer smooth so I filled them with JB Weld and smoothed them out. These areas were filled/sanded/filled/sanded until they were smooth. Any filler on this project that was applied to bare metal was JB weld, not bondo.

    The chassis and bed were primed using Sherman Williams Kem Bond HS. It is really thick and took a solid week to dry. This stuff is ROCK hard!

    I then sanded everything until the finish was smooth. There were only a few spots which I filled with a couple of applications of professional body filler, sanding in between coats so that they were perfect.

    The next coat of primer is applied and I will be sanding it tomorrow in prep for the paint.
