Well, so much for that theory, it clearly is cast iron. Square cutouts for the carriage bolts seem like they were made for a larger bolt, hence the welds I guess.

Jim,
This post isn't directed at you specifically - tagging this post to your response seemed like the most coherent way to update my Yost 33C information.
I ordered a set of Swivel Locks & bolts from Yost about a week ago. They were $12.50 for each set (carriage bolts come with them) + $7 postage.
I really didn't want the carriage bolts as I assumed I could replace those with hardware store items for a fraction of the "Yost Cost". However, that wasn't an option. They come as a set.
The Swivel Lock sets arrived yesterday. I knew I needed to do some work on the old bolt heads with a pneumatic cutter. It seemed like it would help to hit the old bolt heads with a wire wheel to knock off the rust and be able to see things a little better.
To my surprise, with the rust off the bolt head, there was now a number visible that matched the numbers on the new carriage bolts exactly. So - apparently - the old bolts were original equipment.
After some work with the cutter and the angle grinder, the bolts & welds were removed. The new hardware was installed and the new bolts work fine to hold the vise in place. So far I don't see why the previous owner thought welds were necessary.
Prior to yesterday I had picked up a 3-foot length of 3/4" Steel Rod from a local Fastenal store. I had cut 13-inches from that rod and added a couple of 3/4-inch rubber tips from a hardware store to make a temporary vise handle.
I managed to break the jaw screws loose with a Harbor Freight T-Handle 1/4" Hex Wrench. I was really leaning on that wrench and either I'm a wimp or that Harbor Freight tool is much stouter than I ever expected it to be.
New 5/16-18 x 3/4" screws were procured for the removable jaws from a local hardware store.
So I'm about ready to take this thing apart and prep it for a new paint job. One last task remains and I'm looking for advice.
Is there a trick to removing the pins that hold the pipe jaws? I've been tapping a little with a hammer and punch but I'm wondering if there's another method for this situation. I've been searching Garage Journal for info but, so far, I haven't found anything.
Best regards,
Scott
