Finally finished the Bison FPU vise I flashed a couple of weeks ago in the "What did you buy today" section. It is a 6" that had seen a little use, but not in many years. Here it is when I picked it up:
It was rusted and bound up (most likely from inactivity). It came apart surprisingly well. A little Kroil and some patience and everything ultimately came loose.
Some sandblasting followed by sanding and bondo
Passed the facing mill over the anvil and one of the jaws to remove some but not all the damage.
The blackening. As far as I can tell, the vise had a phosphate treatment on the hardware. I'm lazy. I had a half gallon of old motor oil handy so I heated the parts up and dipped them in the old motor oil to give them a little protection from oxidation.
Brush painted everything with Rustoleum hammered. I wanted to keep the original handle so as you can see, I cut off the end about .75" short of the ball. Drilled and tapped the bar, turned and threaded the ball. I lost that .75" of leverage, but I can find it again if I need it. Added a couple of rubber washers
Not wanting to drill more holes in my home shop workbench, I cut up a piece of a 2" laminated beam and made an "adapter" out of it. I made three nuts tapped 1/2-13 and recessed them into the bottom. Now I can put the POS vise back on the bench if I have some heavy welding to do.
Really wanted to mill off the top of the fixed jaw, but didn't want to loose the stamped info so I decided to leave it
Here are a few pics in situ showing the now black "adapter".
Once adjusted it opens and closes smoother and more true than my Wilton. There is no wobble, play, or end play in the dynamic jaw.
During assembly I discovered that the gib adjusting screws were not contacting the gib. The threads were damaged on all three adjustment screws. I don't know if the original owner damaged them or if they were not turned down enough when it left Poland. This issue may have been giving the original owner fits as the vise was pretty sloppy the way it was. By taking about .125" off the threads of all three screws, proper contact with the gib was achieved and everything works as it should.
A peculiar side note. While looking at images on the interweb I discovered that when new, these vises had a sticker afixed to the top of the dynamic jaw warning to not strike the vise
or the anvil with anything. Not a problem for me, but they maybe shouldn't have put an anvil on the vise to begin with.
Date stamp shows 3/65 so its coming up 60 years old. I think I breathed enough life into it to get me to the end of the road......
