Now on to my bench! 

So here's the old thread I started asking about taking it apart, some cool rusty pics in there.

And I'll start with a before and after:



I soaked small parts in evaporust. That stuff is pretty magical. I tried soaking the larger parts in vinegar. It helped but it's not as effective. I still spent a fair amount of time with wire wheels, because the vinegar soaked stuff will flash rust quickly, and the other parts need the black stuff cleaned off. And my sand blasting gun didn't work well... I think I need harsher media than walnut shell. 

Made a wooden handle to replace the steel pipe one.  I used a 1/2" pipe threading die on the ends, it basically just tapered it...



Most of the parts... After soaking and cleaning the lead screw, I doused it in WD40 overnight then teflon spray before assembly.



Primed with rusty metal primer



Fresh out of evaporust



Closeup of the machined lead screw.



That's all for now. Any questions class?

Thanks for looking! Hope the photos worked...

Here's my screw soaking rig :

If you want a fine sand try #5 sand or sugar sand. Removes the light to moderate rust and may even leave the material smoother.

I use "Black Diamond" from Tractor supply for blasting. Very happy with it.

I'd like to see how they machined that screw.

It looks naked without the rust.  Was good to cover it with paint.

Black Diamond is a pretty good general purpose media IMO. Leaves an acceptable profile for coatings. Sugar sand is better for smoothly machined surfaces as it doesn't destroy the surface finish, it may in fact improve it.

Very nice job on the vise refurbishment! A quick suggestion on the handle - if you have a couple of 0-rings to slip over each end of the handle (snug fit) it will soften blow each time the handle travels end-to-end in the housing.

Funny you mention the orings, I brought some home Friday to try out for size!

Yeah I bet machining that screw was a scary experience lol. Hopefully they started with a fairly soft steel and hardened it later.

I chose walnut media because I don’t have a cabinet and I don’t mind walnut shells on my driveway (of which I have lots now). I think I’ll find a big box of something and at least mainly contain it and try the black diamond. I’m also going to try a smaller nozzle.

Me too!!!!

Piece of cake. Cut the thread on a lathe or threading machine, move to mill and cut the relief using a cutter with concave radius to match the root diameter of the thread. There could be other ways to skin that cat.

Nice lookin vise...
