I purchased a 10x36 Cincinnati Hydra-shift that is in decent mechanical condition, but is about as ugly as they come. I'm guessing that it was in a shop in the 1980s when things got slow and someone was told to paint the lathe. That person didn't clean the lathe first, so that is why I have the blotchy mess that it is today.

The lathe was well equipped with accessories. Taper attachment, Aloris tool post, two sizes of center rest, follower rest, faceplate, drive plate and micrometer carriage stop.

One of the first projects was to disassemble the tail stock

I am disassembling the parts that need attention, and to make cleaning and painting easier. So far, the belts are the only parts that I see that I need to purchase. (other than paint)
I'll add photos as the project progresses.

It's probably small by Cincinnati standards, but it's double the bulk of my Clausing 5914 12x36.

Bulk is definitely a good thing, and Cincinnati never built anything light. My 13" TOS is right at 4k. Mike

I've always loved and respected Cincinnati equipment. This thing is huge for being so small! Looks like you have a mighty fine machine there, regardless of the crappy paint job.
I'm envious!:tranquility:

That's really looking good, and the color is easy on the eye's. I guess soothing is the word I'm looking for. Mike

I have the lathe almost ready to paint now and am in the process of changing the oil in the head, gearbox and apron.

I made some serious headway over the weekend and tonight. The lathe is completely painted now, and I have part of it reassembled. I have to re-install the lead screw, fill up the oils, as well as a few other odds and ends, and then it'll be ready to go.
Here is a photo on Sunday morning when I moved the lathe into my shop, since it is too cold to paint in the un-heated area of my barn. I made the cart to move a Bridgeport, but with a few clamps and some steel, it works great for a lathe also.

Here is a before and after photo of the chip pan.

With Wet Paint.

I even removed the levelers and cleaned them up (they were a real mess)

And here it is with the majority of the parts installed.

Before I push it against the wall, I plan to install a DRO on it

Those are nice machines. It's been a long time, but I spent many hours on one just about like that one.

Thanks,
The wiring blueprint that is in the electrical panel is dated 1959. I like all my machines to be newer than I am, and this one barely made it.

The machine is up and running and I'm loving it. Working on some feet for it now, and once they are done, I'll be able to move the machine against the wall. This video shows how easy it is to shift with the "Hydrashift".

My first project is to make some feet for the lathe to raise the lathe a couple inches to make room under the chip tray for a drawer cart that I have. This video shows a neat feature of the lathe, where you can engage the x and y to turn a taper (not customizable).

Here are two of the 6 feet that I'm making.

Wow- you did that restoration lightening fast. Makes me feel like I'm moving slow as molasses on mine. Great job!

I still have a few small items to finish up, but the lathe is in it's final position and ready to roll!!!
I put the feet under it tonight and leveled it up. Sure is a good feeling to have all that work behind me.

Here are some photos of it in place.

That is a fine looking machine. Now I have another machine on my Craigslist watch list. Wonderful job bringing her back to life.

Off topic, but can you comment on your tool holder holder seen in this photo? Is it commercially made or self made? Looks really nice!

It is one that I made. Very simple. Just tacked some metal strips on a backer piece. I'm not in the shop now, but I think for my BXA holders, it was standard 1.5" stock.

Thanks for the explanation! The thin flat stock is smart, as I was trying to figure out how I could cut dovetail holders without a mill. Super smart. :)

Thanks. Tilt the rack up a few degrees and they will stay in place in case of an earthquake .
I fastened a magnetic strip on the back side that holds small wrenches and lathe tools.

I am probably incorrectly posting the question, but here goes - - - What brand and model DRO kit did you install ? I am considering installing one on my Cincinnati 12-1/2 x 36, and yours looks compact on the cross slide. Also, are you satisfied with how it installed and in its performance?

Your lathe looks and sounds nice.

Paul,
I bought my unit off of EBay for $423.00. The seller is Quality Machine Tools, LLC (I'm sure you can find them with a eBay search) They are out of Pennsylvania and I talked with them on the phone before I ordered it and they were very helpful to know exactly what to order. The unit is obviously out of China, but they stand by the units and if you have any problems, there is someone you can talk to. . I mainly wanted to order a display that is specifically a lathe unit, rather than a universal lathe/mill display. Mine has worked good for me, but I'm not a power user. Installation was very easy. Only issue I had is that my following rest will not work with the DRO scale installed on the cross slide.

Applied paint to some of the parts. Sherwin-Williams Industrial Enamel HS - Tinted to Vista Green.
Sorry to dig up an old thread, but I don't suppose you have the colour formula for your paint do you? I'm also restoring some machinery, and the "Vista Green" Sherwin Williams supplied is a lovely shade of bright mint green that looks like it would go nicely with some candy stripes on the wheels. Not quite what we were after. I am not sure if it's the wrong base or just completely the wrong formula.

I'm not allowed to post an image of the label, but here is the info on the receipt:

IN EN HS PURE WHT
Color: B002 BW-27-20 VISTA GREEN
BAC Blend-a-Color 0Z 32 64 128
G2 New Green - 24 - 1
Y3 Deep Gold - 13 - -

Thank you very much. So that was a colour match rather than a stock colour? I've seen a few examples of colour matches to Vista Green and they all seem to use Ultra Deep rather than Pure White base and have a strong blue component. The colour they used for our paint is an old stock colour in their system, but it's obviously not "Vista Green" in the sense we are talking about here. I wish I could post a photo because bright mint green looks pretty hilarious on a big mill!

I brought in a piece of the lathe that they matched it from. (It was part of the center rest, which looked like it had hardly ever seen daylight, so the color was very original)
