The US Army mobile machine shop, 1943:
That sure looks like a fine set-up -- have to wonder what "we" paid for it. And the sad part is, in 3-4-5 years (if that long), it'll be shuttled off in some corner of a base and left with a door or window open, uncovered, and sit there to be auctioned off in 15-20 years after the electrics are ruined and totally out of date, and everything else rusty and dusty.
Impractical. Does the government actually own any of these, or is that from a prototype or sales pitch?
Pacer, I think you have it right -- but not just for the military. I just bought a Mitutoyo CMM (coordinate measuring machine) off the surplus list from SLAC (Stanford Linear Accelerator Center -- a research facility funded by your tax dollars and mine The good news is that it only cost me $80. The bad news is that it sat unprotected from the weather on a loading dock for many years. My first step was to use about a gallon of EvapoRust to remove the rust from the (formerly) very precise THK linear ways and bearings. The balls were unrecoverable (but easily replaced). The electronics are missing. It was only used for a couple months -- until they determined that they couldn't use it successfully for beam alignment.
I'm still optimistic that I'll be able to recover it to a level useful for an HSM (i.e., some semblance of its former accuracy).
Just for grins, here's a picture of a corner of the machine shop onboard the USS Midway, a late/post WWII aircraft carrier, now docked as a historical display for the GAP (Great American Public) in San Diego harbor. Looks like the Navy got to carry heavier iron
Heidenhein makes good scales that you could most likely repair your CMM with. I've worked on Boice and Hansford CMM's a bit. Mostly pretty straightforward.
Thanks. I'm hoping to recover the existing scales. The linear scales, the read heads and the preamps are there and appear OK. I just need to reverse engineer the preamps and go from there. (Anybody have any inside info on Mitutoyo CMM electronics? My main issue is with rusting of the linear tracks. Plan is to dissolve the rust (done) and hone the tracks with diamond paste.
I have a copy of some older, but still useful, IMO, software for CMM use. I'd have to think about the interface a bit, but as I recall, it's not too complicated. This software is PC based. It comes from Caliper Designs.
Thanks. Any info on the electronics and hardware would be especially useful. (I plan to rewrite the software, since it'll probably run on an embedded system.) But the software would be useful, too, especially insofar as it helps me define the interface hardware and timing.
I'll dig it up, Mike.
Neat ship! I took the family through it 2 years ago and we were all amazed.
The biggest issue with the mobile machine center is the armies policy that no feild fabbed parts will be installed. While I was in Iraq we had several issues of air leaks and could fabricate a perfectly usable replacement hose but were not allowed to since the replacement part did not have a NSSN and may or may not have been compliant with some obscure, esoteric standard. These were all MRAP vehicles built by International, nothing special other than the armor. It was very frustrating to hold a vehicle for one simple line and wait 7-8 weeks for it to arrive. Happened too many times to too many vehicles. Hated that aspect of that job.
The machine shop on board a Navy vessel was always a much nicer and more convenient work center than anything transportable by the Army. When the Navy moved to a new location, the machine shop didn't have to fold their tents. When the Army moved to a new location, everything had to be closed up, folded up and packed up. We had a machine shop truck in our company in Viet Nam that looked like the WWII machine shop in the picture. The sides opened up and the floor slid out on both sides. I think it opened up to about 15' wide, IIRC. Sometimes I think I would like to have one of those old machine shops on wheels, but I get over it and say "naw"
That is a huge lathe aboard the Midway-
What type was it?
That's a beautiful machine.
Way too big for my tiny home shop, but still, nice.
Some more Army mobile machine and welding shops!
Ordnance Maintenance Truck, 2 1/2 Ton
There were several types of trucks beyond those pictured below, including the automotive repair truck, for general vehicle maintenance; the electrical repair truck, for various types of automotive electrical equipment; the instrument bench truck, to maintain and repair special fire-control equipment; and the tire repair truck.
Thanks, Allthumbz, for the neat pictures and history!
Wonder how uniform the lathe cuts were in the presence of "incoming"?
Mike (who's workshop is about the same size and even more crowded, but not mobile, even though it's in a garage
PS: BTW, I should forward this thread to a friend who is now president of the MVTF (Military Vehicle Technology Foundation; check it out at http://www.mvtf.org/ And if you're ever in the SF Bay Area, you simply have to do a tour.)
Here is another modern mobile Army machine shop for sale on Ebay:
