I finished up a quick refurbish of a '50s (?) Columbian 504 vise. Really just a disassembly, de- grease, wire brush, paint, reassemble sort of thing. But man, it works like it probably hasn't in a long, long time and it looks pretty good. Backlash was 2+ turns and is now less than a 1/4 turn. It's a nice addition to the more modern Yost.

Always nice to bring one back to it's former glory. I think tools, cars, and such respond to love and attention just like we do. Mike

More progress on the lathe upgrades. Took the end cover to the Mill to enlarge the bore to 2.750" in preparation for the spider build once the machine is running. I took advantage of correcting the holes center location. Needed to move the hole up .0375" as original hole was .075" off center low. The bolster has come in handy once again for quick setup for this operation. The spider will also contain the magnets for the tach pick-up.
Made a the tachometer bracket from scrap .125 aluminum. The tach will live just under the DRO and shares the same mounting bolt.
The last piece of the day was a milled block of CR 1/2" for the Hall sensor. The block is screwed to the carriage with two 10-24 s/s button head cap screws. I still need to radius the corner facing out.
Mark also completed the wiring on the lathe itself. Final VFD command logic connections are left as well as programming. Getting so close to completion, I had trouble falling asleep last night, couldn't shut my mind off despite being tired. Very stoked to see the features and options this system will provide.

Looking good Paco. You guys are making fast progress on the install.

Ha Ha The inside is painted. The first try at it I had some issue with my gun and got a bunch of runs. I wasn't able to wet sand them out so I had to re-paint about half of it. I'm pretty rusty and it still isn't great but it is what it is at this point. The front turned out best which is what I'll see the most so that is good. I had to pick up a cheap HF gun this morning as my good gun is totally messed up.

Sandon what paint did you use? I am going to repaint a lathe this spring and Im looking for some paint options

seasicksteve,

I used the Omni line of single stage urethane. I had most of the paint products leftover from other projects so I only had to purchase a quart of high build primer and a quart of color. I'm not a fan of rattle can paint so went with the 2K urethane. Overkill for a lathe stand but it does look good. LOL

If you have a paint gun (or just buy a cheap HF gun) another alternative is to go to your local farm supply store and they will have equipment enamel in quart cans in several "tractor" colors. I would use some hardener in the paint or it will take forever to dry. They didn't have the color I was looking for but they do have a medium gray that I will use for a grinder stand that is next on the list for paint.

I finally got out to the shop and was able to make some progress on my bench grinder rest, as well as play with the new camera (yea for 4k).

Stupid photo wont rotate sorry.

The vice re-haab in post #6511, above, reminded me of a project I did last week. Along with other equipment from the previous shop my son acquired, was a fairly new Harbor Freight 4" vise. It rattled and wandered about, just sloppy as expected. My first thougth was to put set screws against one bearing surface to take out the wander, but found it was tapered. Snug up the set screws with it open and it wouldn't close. So. I figured out the taper and put the top section in the mill vice (with half the taper up) and cleaned up that side (about .020), turned it over and did the same on the other side. It came out parallel within .001, good enough for me. I put it together and guess what, the jaw was .040 out of location, and .010 out of square. A piece of .010 feeler stock solved that problme, and a piece of 030 brass solved the other one. Now it's out .010, but you can't see it. In the picture below, you can just see the upper left corner of the brass and the right edge. I couldn't figure out how to keep it up on the wear surface without using the whole piece.



On the other side you can see the set screws (tipped with brass to avoid erosion). It now has about .003 slop.


Its hard to believe it's the same vise.
