Awesome rotating Parker km!
Here is a nice Parker 439 on a interesting stand.



According to the Mohs hardness scale:
Aluminum: 2 - 2.9
Copper: 2.5 - 3
Brass: 2 - 4
The Mohs scale is one that rates scratch resistance. IMO: The copper jaws are more aesthetically pleasing, especially the polished, vintage ones. However, I use aluminum because I have a lot of raw stock in my shop. Also, it's a lot cheaper than copper. Looks like if you want a harder material than aluminum, brass is the way to go.

Guys, you were right... I have not even touched the 180lb McAvity vise yet and voilà!... another vise finds a new home in my shop. -- A Prentiss No. 2.
Except for a 2" long crack in the slide where it seems nails were being straightened, it is in great condition.
I did not find any other Prentiss no. 2 in the forum; is this guy alone in the world?
Here's a picture after coming home from the auction house, and I could not resist even if the temperature is freezing here to take it apart and give it a quick clean.
What would have been the original finish on these old vises? I would assume they were sold bare metal, but I could be wrong.
Maybe if I get some heat in the shop I may tackle these vises this winter, otherwise it will have to wait till summer. I'll post the finished product in the 101 thread.
CW: I actually thought of something similar. As it turns out this vise has a feature that would take care of most of that. The spindle bar has resistance built into it so that it will stay where you put it whether it's all the way to one side, all the way to the other, or somewhere between. Now I'm thinking that screw was either for putting resistance on the slide or that it was for some kind of a jig (do you call them jigs?) and it only incidentally went in far enough to hit the slide. I haven't done much tapping but I think it's easier to tap a through hole than a blind hole. That's my working theory as of now. And you thought that you were rambling.

Outlaw-So then would the doohickey in question (crs's Parker)make that kick up sease and cause the leverage to pinpoint onto the jaws to tighten harder with more even jaw pressure? (and put more uniform pressure on the lead nut)?
Would the doohickey act to halt the slide kick in the gap within the slide cavity for completely even jaw pressure?
Newbie here in this world of vises...

Not vise of the year
Does anybody think this one can be saved? Parker 288 1/2
Seller asking $100 but that is clearly "optimistic"

Nice bagged. Good candidate for the electrolysis tank!
Dave, many were painted flat to satin black, but it wasn't
universal back then. Parker had an "economy" line that was painted green...
Bagged-what do you do to clean the piece off after it comes out of your e-tank?
What is blo?
What is blo?
I believe Boiled Linseed Oil.

Pete: Very nice couple of vices. Welcome to the vise thread
Jake: I think you mis spelled Fretters?
Okay vise fans: The mystery deepens. I checked the Parker 239X and the dingus. First, I took the dingus out. (No off color jokes please.) The only thing unusual about it is that it has been filed flat at the tip. Next, I examined the vise. There is no play in the slide. None! Up or down or side to side – no play. I looked at the top of the slide where the dingus hits it and there is only one circular spot. I expected to find a scratch pattern along the slide as wide as the dingus or a series of circular spots. One spot only. Next, I looked at the jaws and jaw inserts. Here is where it gets interesting. With or without the dingus they fit together perfectly across the top and on either side. The faces of the inserts are even more amazing. They are smooth and dead flat. I mean bagged smooth. With no attempt at clean up, I could see reflections in the faces. When the jaws come together the faces meet without the slightest gap anywhere. No gap!
The mystery continues. The garage shop where we found this vise was a woodworker’s shop. He had a nice bench with a Columbian woodworker’s vise. One possible clue to the Parker may be that the owner had a large collection of wooden hand planes many of which were user made and of GOOD quality. I suspect that he needed to do fairly precision work to make the planes. However, that still doesn’t explain the dingus. Maybe it just served as a lock for when the vise was not in use. What do YOU think?
I managed to pick up these two recently
.....
and a 4" Swindens to go with my 6", these vises cost an absolute fortune new, the 4" is something like $1200, so I was pretty pleased with 60

So there is one spot on the slide where the dingus, lol, tightened into the slide?
Big Pete: I'm not very familiar with English vices but that Nubo looks like a real workhorse. I would like to see both of these when you finish redoing them. Please be sure to post them here. By the way, have you posted a vice on the Vise of the Year 2015 thread? Here's a link:I managed to pick up these two recently
Nubo 4", looks like it might be late 30's vintage

The paint looks like it was put on with a stick, but I'll strip and clean it up when I get some time, ditto the Nubo
The Nubo came as part of a deal from my local scrap dealer, I was mainly collecting steel stock, , less than 40 bucks all in, including 100lbs or so of steel.
Yes there is only one spot on top of the slide where the dingus touched the slide. Suspiciously, they will only line up with each other when the jaws are fully closed.
Then sounds like it's just a lock when not in use...strange. What's that purpose? Keep the kids from using that vise?! Ha.
I have a bench of vises only I can use, and another everyone else can beat on!
bagged: I'm stymied for now. I suppose it could just be there to keep the threads clean until something else was attached to the hole. I realized that there was one other clue as to how the vise may have been used. When I dusted it clean there were no filings only sawdust.My guess was some other tool was bolted onto the vise. I don't see a reason for a lock like that?
