Quick Wilton Question - Welding on Screw

[gm54210]

Is the screw on an early Wilton (Chicago) machined as a single piece, or in two pieces? (screw and nose piece) I ask because I am in the midst of repairing a broken screw - that had been previously "repaired" badly. The PO had done something similar to "welding" to reattach the nose piece to the screw. It was a mess, globs of weld on top of welds - and crooked to boot.

I cut out the bad stuff and created a mortise and tenon with a shoulder. I've got a friend that is going to look into putting a TIG weld around the shoulder. My friend was asking how it was made originally before he tries anything.

Think that would work?

Good question. I have owned about 15 Wilton vises and still own a few and I really don't know the answer to your question.

I would guess one piece. There are a ton of Wilton vise restore threads on GJ that usually have pics of them taken apart that might help you. Also I think bluebolt had a Wilton parts vise on the classifieds that had a good screw. Or check the other classifieds.

I'm sure you and your friend will do a great job, but if you are doing for resale a replacement would be the way I go. Search the threads with Wilton pics until somebody can find this thread that knows the answer to your question.

Good luck, D

Most vise screws made within at least the past 30 years are friction welded to the head.

One piece construction. Think about the amount of rotational force put on that screw when being tightened. How would they secure the threaded rod into the operating nut and not shear whatever they used to stake them together?

I agree with A_Pmech. You can tell by the rough burnt look as the screw meets the handle block. Friction welding works very good, how many vises out there have come apart.

Friction welding (FRW) is considered as a solid-state welding process that generates heat through mechanical friction between a moving workpiece and a stationary component, with the addition of a lateral force called "upset" to plastically displace and fuse the materials. Technically, because no melt occurs, friction welding is not actually a welding process in the traditional sense, but a forging technique. However, due to the similarities between these techniques and traditional welding, the term has become common. Friction welding is used with metals and thermoplastics in a wide variety of aviation and automotive applications.

+2 on that one big guy!

I do have a main screw for a 5", no handle, pitted badly where the handle goes through.

From the description, your machining and welding will be sufficient. What would have been better would, instead of a 90-degree shoulder, making it a 45-degree so your welder could fill the vee with weld. Still should work fine.

And this thread would be so much better with pictures!

Yes that would have been helpful. Naturally, I thought of that - AFTER he took it along with him.
The vise is a 4", I don't know if the 5" would fit. Thanks for the heads-up on the replacement, and thanks for all the information.

We'll see what I end up with. It may be a bust, but I'll only be out $10.

Thought I should update everyone.
I got the screw back nicely welded (TIG). I had to file a bit down to gain clearance, but there is still a nice fillet on the weld.

It's not perfect, but it runs true and seems to be a good deep weld.

So, now I have the 4" to go with my 3" and 5" Wiltons!

Thanks again for the advice and encouragement.

GM: i didn't get a chance to read all the way back on your thread, but it looks like a success story and congrats on that save. wanted to know if that is the dark grey hammered rustoleum or what is the color and make of that paint because it looks great?

Yup, Rustoleum Hammered - black. Thanks

Looks a bit under filled, but should hold up fine.
