Default Leg Vise Restoration

Well maybe. We will see if I am successful.

So I have 3 leg vises. I am starting on the one that is in the worst shape.

A previous owner really fucked it up. The they ground off the key on the
thread box and then used some key stock and a wedged to lock the thread
box into bore of standing part of the vise. Then ground the hole in the
moving vise jaw for clearance.

The leaf spring is also missing, and they substituted a coil spring. So I
need to get some 1.25" high carbon steel and remake the leaf spring.

Also the wedge for the foot and yoke mount is missing and needs to me
fabricated.

So I have the vise apart, I cleaned wire brushed and in some cases
sand blasted some parts to get the dirt and corrosion off. I hit it with
some spray paint, black epoxy paint to stop any flash rusting. This will
be mounted outside the shop in an area that will also have my anvil.

In the second picture you can see where the key was ground off the
thread box. Silly humans.

The remaining pictures.

My original thought was to mount the vise to my table. But now I am thinking of making a separate stand so I can move the vise around.

If these things were always used as they were meant to be used, not one of them would need help. I've seen so many just mangled to ship and really not worth much more than scrap prices for the metal.

Of course, give a man a piece of pipe and he thinks he can hold anything.

Applause Shade on giving them their new life.

Ypou could mount the vise to an upside down chunk of train rail and it would be portable as well as having a anvil of sorts. Just make some 1" pipe legs so it is like a saw horse.

Shade contacted me off line and asked about a new spring..

Today the school of thought and even videos out there say just to use "Mild steel".. Bah, humbug..


I was informed it needs to be about 1.25" wide.. Trailer springs come standard in this size.. some are 1/4"X 1.25 and others are 3/16X1.25..

I always make my vise springs out of 5160 as this is what the leaf springs are usually made of..

In the olden days they used special spring steels for nearly all springs made..

My recommendations is to use one of these leaf springs and for the price of them you can have other blade or spring stock hanging around.. last 1 I bought was 35.00 and it had 5 layers..


Ron if you were closer I'd just give you some.. In fact we could just forge it out..

These springs usually don't need to be hardened and tempered.. Just be sure to work the metal at the right temperature and don't over heat the spring.. REmember when you bend the upper lip to have a round corner on the vise or side of anvil so there is no cold shut or forging stress crack..

Then with it as forged ( and cooled in air after forging IE left on the side of the forge) assemble the whole thing and see what kind of set the spring takes in use..

Ideally you want to put more spring into it and will lose some when used..


Forge the bottom first by adding a taper slightly smaller than the width you need.. Now peen the middle with about 3/4" off the side of the anvil..

Like here in this peening video..

https://www.shopfloortalk.com/forums...239#post714239

then bend the side lips up.. The finial thickness should be about 1/8" where the spring meets the lower leg and is should be slightly rounded with 2 wings left on each side of the leg..

Just let me know if you need more info.. sorry I haven't been around much.. Life is just SO busy..

I got the 5160 ordered last night. 1/4" x 1-1/4" x 36" One of the other
leg vises needs a new spring as well has it has been welded. Now I am
looking at building a forge as well.

Nice..

Be sure to round both sides of the spring and make as smooth as possible..

In the old days they had swages that were slotted and the top and bottom sets were used to radius both sides..

The other way to do it which is what happened at the factor is to flatten round bar and this will create the radius needed all on its own..

Of course today with rolling mills it's a no brainer..
