We have been talking about spindle nuts and threads lately and I wanted to add a few examples of thread types and a few pictures.
Is there a name for the threads used in Record (UK) quick release "fitters" vises?

That looks like a Buttress Thread, The British use buttress threads too. My Record # 53 wood vise with the quick release has a buttress thread. Mine measures .960 x 4 threads per inch.
I can see cutting this type of thread, but why the negative rake.
I believe it is to keep the halfnut engaged under load. On the Cardinal vises, the "undercut buttress" thread holds it tight with no springs, etc.
I need some help identifying this vice. Any ideas from the gurus? I have no idea about where it came from. I acquired it from a flea market and didn't get any background on it. No markings from what I can see.

anyone have comments about a Wilton 1750 vise

Stellar!!!! Such a beautiful vise too!!
Hey, can I borrow that this weekend? I need an attention getter for my yard sale.![]()
My Latest, picked it up earlier today.
An American Chain Company, 5 inch jaws, fixed base, and with a slide limiter. Check it out, the screw is longer than the slide and is held in place with a yoke. It bathroom scale's at 78lbs. Am going to take this guy apart later, it looks verrryyy interesting .
One side of the vise reads
MFG. BY
AMERICAN
CHAIN CO INC
The other side reads:
A C C O
BRIDGEPORT CONN USA
It is missing one jaw - this will be hell to find, looks like a job for the MillRite. The missing jaw resulted in a price drop - $40.00 to $35.00.
I spent the last couple of hours on the Internet trying to find information on American Chain vises, found nothing. There is some info an American Chain, so I am going to to go down that road until I find something or it dea ends. Checked Goggle patents to see if I could find any info on a patent. No luck, but tomorrow is another opportunity.
Anybody have any info on American Chain vises?

We have a new member named Jon Jacobs....
And this is what he made and just posted on his thread...
I thought it was worthy of including in the "Mother of All Vise Threads"...
The boy "Dun Gud"...
How many do you think he could sell/give away/distribute???
Beats the stew out of a broken/missing retainer...

"I have a list of over 450 companies which manufactured vises and this is my first American Chain Co. vise. Thanks for sharing!"





Well.. Another successful day. Bought 2 today, got the Wilton from zoomieport, great guy, and has an awesome collection! Thanks again for my first Wilton!
Someone must have dunked this thing in a can of red paint multiple times!

Mine looked just like that when I got it. I wonder if it is the same person doing the dunking. He should be arrested for the red. Nothing a little paint stripper and a wire wheel couldn't handle. It will look like this in no time.

Found this rusted forgotten relic under a pile of junk at a friends barn.
tore it down and brought it back from the dead, painted it, polished up some parts. straightened the main shaft and it now runs like brand new.
Interesting thing about this vise, once I stripped it I found hallmark stamps on every part. Did some research and found out this was a military piece that required certification. These type of certifications were done on tools used in weapon and advanced aircraft repairs areas.
will see if I can get some, the vise is now at it's new owners. I will see if he will shoot a pic or three for us.Can you take pictures of those marks? Because I have an old American Scale vise and I think it came to Holland during the first or second world war. So maybe my vise has got some marks as well???







Also, I am debating; should I restore it or leave it as is. I would like to get/make a handle and mount it on my bench for light use.
Anyone have a lead on a nice handle?

oldldh, link to the thread?
Thoughts on this one? I might snap it up and restore it.

Any chance you chaps who keep linking to Craigslist listings could add a photo along with the link in future? I'm sure I'm not the only one who either can't or won't view that site. Makes it a tad awkward to follow the plot without a photo.![]()
