After discovering that all our old posts from years back can still be found together with their photo’s I just added this post to see if it appears today
Also, I note, where I’ve quoted Michael for my reply, the quoted text is smaller, less dominant, and italicised for emphasis.
The developers do seem to be listening. 🙂
Bill, maybe I’ve lost the plot but I don’t understand what you mean about comparing with the original post?, I thought this was the original post and the images etc are still up at the top of the thread
It’s hard to tell for sure on the rest of that vise, but the shaft and those mottled colors are what’s generally referred to as color case hardening. A few of the older Starrett tools had the same. Some older sporting and especially lever operated rifles as well as some hand guns also used it on there actions. There’s various methods of doing that type of coloring and case hardening, although none of them are all that simple or quick. Given the patent date of that vise and at the usual industrial production numbers, I believe one of the most used methods was suspending the part in a molten Cyanide bath for exact time periods to do both the case hardening and coloring.
There’s another method called pack case hardening that uses an almost totally sealed container with high carbon materials surrounding the part and then heated to well above that high carbon materials burning point. Bone Meal, actual ground up bones, charcoal, large fruit pits etc can be used to drive carbon back into a low carbon steel and then allow surface hardening to occur. For the obvious reasons and workplace health & safety regulations, I don’t think that molten Cyanide is still a method being used today in at least the more developed nations. And just in case you don’t already know, those colors are fairly delicate since there only on the metal surface. Using anything even slightly abrasive on a color case hardened part can easily start to remove them. And for any tool that does have that coloring, it would be fairly safe to assume it isn’t something that was cheap or poorly made. $4 for your version in 1894 would have been a fair amount of money back then.
Vic, I think they are talking of looking at an archived copy of the thread to see what it looked like there and comparing it to here
Oh, I see, well I think I see as I’m still somewhat confused as I presumed this thread came from the ME archive?
Sorry if I wasn’t clear enough in my explanation (or lack of it).
archive.org is a useful web site which scours the internet looking for interesting websites to archive, or take a snapshot in time if you like; once that snapshot it taken, it doesn’t update, though later shapshots may be taken and saved with a different recording date.
It doesn’t allways save all the contents of a site; Unfortunately in this case Vic’s post wasn’t archived even once, so I couldn’t see exactly how it looked when it was originally posted back in 2021.
I was trying to see why the picture Michael thought he had inserted wasn’t showing in this thread, now that the vice discussion has been transported to the new version of the forum.
This is all that showed on a Windows PC with Opera browser.
It looks like that odd little icon showed on Michael’s Ipad as a Question Mark, as his operating system is different to mine.
It turns out it was actually a “Thumbs Up” gif, hosted on the previous forum’s software (so it desplayed ok on the original greenish forum), but the gif database was not transferred over here.

Just to elaborate upon Bill’s excellent explanation … here’s what my post looks like on today’s forum:

The Question Mark indicates that iPadOS recognised something was missing, but didn’t know what.
The stem of the vise is definitely colour case hardened, I own a late 19th century muzzle loading percussion shotgun with browned Damascus rose twist barrel. I acquired this gun back in the 1960’s and the original brown finish on the barrel was poor but the original rainbow colouring was still on the breach block and plug.
I took it to the nearby Birmingham gun quarter to get it re browned and left it with them for a month or so. When I went to collect it they said getting the breach unscrewed was extremely difficult and fitting it back they couldn’t quite align the marks under the barrel. He then proudly announced they had “reblued” the breach block etc and it was now a horrible dark blue/black colour. So in essence they ruined the original finish which would have been done in a furnace with old leather, bone dust and other bits and pieces using a secret recipe passed down.
