This was what I was thinking, although annealing and stress relieving the U-Bar after forming, and then tweaking the bar to ensure parallelism might prevent warping.It would still be a PITA to get them completely parallel regardless of the cast in place method used. heck just the heat of the casting process would change things.
Does anyone know the diameter and thread size for the main screw or where I could find any reference material ? ThanksAmerican Scale #2 2-3/4 jaws and weights 10lbs.
Stupid question. What does the "Auto Vise" look like?
1Bad55: Here's a 1915 ad for Rock Island's Autovises. They seemed to be a general service vise but aimed at 'car guys'. There were a couple of other vise companies that marketed auto vises too. It seems like even back then, marketers wanted to get with the latest thing. There was even an Electric Vise and, a few years later, a Radio Vise.
Hey KMScott is there any information or resources on information regarding the American scale co number 2 vise ? I have one that I’m trying to find a replacement screw for and with the wear on the internal threads of the static jaw and tight space it’s in I’m really struggling to measure the thread dimensions the threaded exit hole of the static jaw appears to be around 5/8” or 16mm however I’m having a hard time even confirming if it’s square thread/acme/buttress etc. if I had to guess I’d guess 5/8 and maybe 6 or 7tpi. Anyhow literally the only info I’ve seen was a sales marketing flyer but it didn’t have anything specific on there so I would greatly appreciate any information or resources someone could help me find.American Scale #2 2-3/4 jaws and weights 10lbs.
Thanks for sharingHeuer 75, 3" jaws, opens to 2-7/8", weighs 6 lbs. This is an early Heuer, newer ones are a little different.
At least one of the vises was probably made, maybe a few more.
Honestly, never seen it. Usually I have a patent number on a tool, or a date. It's rare for me to be reading SA just randomly looking for stuff.^ We know for sure that all kinds of items in "Scientific American" for which there are write-ups were in fact not actually ever produced. This has become an on-going issue for the stewards at datamp.org, as some of the articles which were published allude to a given item actually having been manufactured, when in fact it was not.
Apparently "Scientific American" had people on the payroll whose business was "advertising" new inventions which had been patented, looking to make a score by selling the patent rights to somebody on an item that had not yet gone into production.
I do not know if that same issue comes up with "American Machinist" as well, but that text in the above-cited article causes me to wonder.
@RTM - your take on this one?
From Datamp, under person Northall^ what are the patent numbers?

I thought the same and asked the owner his thoughts. He came back with this pic.I'm thinking German - seen several similar from Germany.
