Thanks guys. I need to find a Littlestown vise screw for a 112. Will one for a 25 work?
Are you sure the old one is a goner? What size is that screw? How many threads per inch?
Looks like you need jaws as well.
I have restored vises that were all rusted up just like that one. A good place to start would be to knock off any loose rust with a wire brush and the. dunk the whole thing in a container full of Evaporust. If It can come apart, that would help.
If not, get yourself a heavy duty plastic bag and put the vise into it and then fill the bag with Evaporust and seal it closed. Then lower the bag into a 5 gallon bucket full of hot or warm water. That’s a lot more economical compared to buying 5 gallons of Evaporust. Keep the bucket warm by wrapping in old towels or blankets or moving pads or whatever you have laying around. Let it sit overnight and check it. You should then be able to easily remove crud under running water with a brass brush or use a pressure washer. Rust will have been converted into a black substance that doesn’t stick. It will leave a black finish on the metal that sorta helps retard rust. After scrubbing, I like to apply a thin coat of boiled linseed oil if I don’t paint.
Unlike vinegar, Evaporust stops working when the rust is fully converted and will not ever eat into bare metal like vinegar does. If you forget about the parts sitting in Evaporust for a day or a week no problem. Vinegar costs a lot less, but it time critical. You have to keep checking on progress and remove the part and rinse before it’s too late.
