I purchased this vise today for $50 at a local flea market. I planned on buying new jaw inserts but everywhere I've checked shows either a T or flat Jaw held on by pins for a Columbian 504 1/2. Mine however are U shaped inserts and it appears they are not available anywhere. Can anyone help me locate replacements? I'm awaiting a response from Wilton. Thanks! 2 screws hold the inserts on

Riggs: i'm not sure why you are trying to replace your jaws because they don't seem to be that bad of shape for a 70 year old vise. can you clean them up with a wire brush on a bench or hand grinder and take some close up pictures?

you can PM KMScott and if he doesn't have or isn't able to make you a pair of new jaws he probably will know where to send you.

or buy a pair of $30 copper 6 inch Wilton jaws that you just set on the vise and most anything gets clamped in tight with that soft copper holding it tight and usually doesn't make any marks on your project. picture of my Rock Island vise with a pair of these Wilton copper jaws attached.

Thanks. One of the inserts is in bad shape. I'll get some better photos in the morning.

You can't tell from the photos but the inserts are warped. Also having trouble removing the screws. I think they may have been crushed in the jaw

Riggs: it's really hard to tell from that picture, but i'm guessing the jaws are homemade and not original. also the screws don't usually get tighter because of the vise and normally tend to rust in place. those flat heads might strip if they are in there tight so maybe spray a little PB blaster or Kroil on them a few times and see if they loosen up before you attempt to take them out.

an easy out sometimes works and just know that they tend to break also so BEE careful and they might come out in one piece.

good luck and did you PM KMScott or find replacement jaws? or can you make up a pair yourself?

I got the jaw off after about an hour of tapping a screwdriver with a hammer. Getting it painted now. Anyone ever bake on paint. I'm curious as to what temperature and how long.

Riggs: i'll bump this up for you so maybe somebody else with a little professional experience will see it and respond. what part of the country do you live in? if it's between 60 and 80 degrees day and night then painting and letting it cure for a couple weeks is optimum according to the directions on most cans.

if you can put the vise in the oven before painting it on low (or warm it up with a heat gun or even a torch if you are careful, then paint and stick back in the oven on low heat or use the heat gun to keep it warm.


if your garage still gets below 40 degrees you might want to keep inside the house until it cures.

i'm interested to hear what the other guys have done or do. also the brides are not always happy about tools going in their ovens so this is not for everyone and why some of the GJ members have ovens inside their shops and garages that the brides don't cook in.

good luck and looks great so far

Thanks, I live in NE Ohio, it snowed here last week but i don't think it will get that cold again. I have it inside now in the kitchen. I don't think she's been in the kitchen since we moved in so its safe there, even more safe in the oven. I'll probably let it cure inside, I have to touch up a few spots still and haven't even built a workbench yet to mount it on. I wasn't sure if the paint would be more durable if I baked it.
