Long out of print and the company no longer in business I have "JakFacts" a two volume reference manual for hydraulic service jacks. This series was not cheap to buy when purchased new some 10 or more years ago and is definitely a valuable aid to repairing all of all types of jacks going back to...
Sorry I'm don't stop on by the GJ too often anymore but looking at the components of this jack it looks to be an old Manley. And yes it would be early twenties for sure.
These grinders were mostly used for cleaning up welds or castings in industrial applications. The way it is configured now with the wire brush is a bit of overkill if I do say so. The design of yours leads me to believe it probably is more like from the 1960's and later. I've owned a few of them...
The angle grinder sander w/the wire brush needs a lot of CFM to run properly. The average single stage home compressor doesn't have enough capacity to keep that type of tool "on the run" for very long.
My cousin has left jacks outside in the weather for years sometimes he covers them with cardboard if it rains. They work fine save for the handles which can rust in their sockets.
I have three Vintage 1/4" drive tool boxes one w/assorted sockets many brands. The boxes are SK, Craftsman w/underlined C and Williams red & black box $25.00 for all w/free shipping.
Next up a hodge poge of electrical wire crimpers, an Eagle Claw Wrench w/early patent date, two I believe...
It is interesting to note that the catalog page indicates that thousands of these box sets have been sold. That is an interesting thought given that this type of box is even more uncommon than the bullet box. The other thought is why do so many of the boxes lose all their tools? You would think...
I read it here somewhere and coincidentally I do own a Metrinch set. If this was the greatest idea on the planet (which it isn't) why aren't all the major makers marketing this style of wrench? I am sure it's all about trade offs as an example Snap-on had Flank-Drive on their sockets and...
From what I have read they have the same slop as the Metrinch Sockets. To me slop in the sockets is not as bad as slop in wrenches (Metrinch wrenches would be almost useless in many situations on today's cars) but preferably I would rather have no slop. Just a thought off the top of my head.
A. Plomb Tools are not Plomb Tools. Alphonse was an alcoholic and left the original company at some point in time in the 1920's. He then started another tool company called A. Plomb which in some manner was connected to California Tool Company. One can find tools with both names on them i.e...
