Good catch, I thought I had seen a machine like that before. Same type machines, but appear to be in a different shop. Most telling detail is the drive belt. Located on the right in both photos, leading up in one down in the other.

[QUOTE=jimfols;204386]I was thinking the same thing when I saw these wrenches.
Saw this today on eBay. $1299 US.
I own some Armstrong tools but I think this should be named Backstrong.

I checked a 1937 Strelinger Cat, and Williams were making up to 7-5/8" wrenches for 5" bolts! 52" - long
$204 then!
A 4-1/4" was a mere $42, by comparison.

6 active spindles, unsure of brand; ACME-Gridley, National, Gisholt, Wickman to name a few. No CNC controls, but effectively autonomous via cams, linkages and gearing. Lots of them still running; and plenty of decent you-tube entertainment to boot.
yikes! that would drive me nuts! ( as I bolted for the door) your screwed! your shift has just begun and your already lagging behind and your threads are torn & almost striped off.!!
Always fascinating to see machinery in action, good stuff. Mr Mikey.

Practically rofl. Either too much invested in big equipment, or no one liked handling small tools. Figures show they equipped more than 500 plants here and abroad. Mesta "machines" can be found in factories throughout the world and as of 1984 had equipment in 500 steel mills. Mesta was the 488th largest American company in 1958 and the 414th largest in 1959. Bankrupt mid 1980's. How on earth?
When/ who ever a liberal yahoo goes on about 'infrastructure' of daycare centers and art projects, I refer to Mesta, Lowey, GE Locomotiveworks, Grand Canyon or Coulee Dams and so on; "No, while this is the scale of infrastructure, but not yet installed, it isn't truly infrastructure. That comes transporting it cross country, installation and commissioning it, and finally benefiting a large population. THAT'S infrastructure! Flat trumps every argument.
Incomprehensible how few get along without an inkling what it takes to hit a light switch, drive interstate highways, transport foodstuffs, build tracts of homes, . . .
I always listened to Paul Harvey on the radio. I see these photos and want to know "the rest of the story". Where did it go, what was its job, etc.
Search YouTude for "Paul Harvey The rest of the story" if interested. (in Paul Harvey, not the giant compressor)
I found this, Starting about 2 minutes in explains about a large compressor similar to the one shown. video
(I also wish I could figure how to put YouTubes in just as a link)
Thanks for posting this video. Good stuff. I like old machines and equipment and antique engines. Thanks again. Mr. Mikey.
Note the initial commentator, in a standard compressor plant, amid centrifugal pumps, ~100hp electric motors, large castings entailing complicated coring, foundations, jackscrews, piping and control panels are glossed over; while oil sight tube, & revolutionary crane on wheels (crane + wheels = gantry, crane on ground = A-frame) a rarity, get vapid "Oh, that's cool" treatment.
Steampunk mentality personified. That's who screws black pipe, steam fittings and pressure gauges together for an electric lamp; leave off gauges, it's a 'industrial' shelf bracket. Everything about appearance, zero on merit, capability, applicability.

Hello, I saw this picture of an old lathe and thought this would great to post. Looks like 1920's. I'm not sure what make this is. Notice the machinist is wearing a tie. Thanks. Mr Mikey.
well of coarse we wear ties.
Best to include a suitable and secure tie clasp. Back in the early days of my career I wore a tie clasp that was a cheap simple silver plated bar to which I mounted a tiny 440 stainliss steel ball bearing.
don't tell Osha lol.

Multiple rope drives driving lineshafts on each factory floor
yup I saw that somewhere I visited. them smart fellers, split the power to any where in the factory.up down over change ratio for something I was amazed whay all they had done with it many many years ago. the down side is...when the power head stops it all stops. but there are addvantages to just one power unit, like put it outa the way.heat,noise etc.
Good stuff. When I was a kid I liked going to Greenfield Village in Dearborn Mi. and always spent the most time in the machine shop, all belt driven. I think I need another trip there. Mr Mikey.
when my wife retires ,I... we hope to travel the country and see lots of stuff like that. thats if there is still a country to see.
What am I missing?
I am looking at that massive "wheel" which appears to be cast in one piece. The hub is bored and spilt. They appear to be cutting the keyway. There appears to be 4 bolts to clamp the hub to the shaft by squeezing the 2 halves of the hub together. Each half of the hub is attached to the outer rim rim of the wheel by 3 stout spokes.
Something has to move when they squeeze that hub down onto the shaft. Does it flex that massive wheel?
Attachment 43315
Hello, I'm just guessing, maybe the shaft and bore clearance is slightly press fit then when the clamping bolts are torqued as runout is measured its in spec.? also since belts are running at a slow rpm its not considered an issue.? Mr Mikey.
If you want to see one (all right, a much smaller one) in action...
https://www.youtube.com/watch?v=jlW3sv9ZKxs
Exactly right, but only the hub, there aren't spokes across the center.
The cutter head has a tapered arrangement with set screws to control depth. Boring a split hub is common, the gap is shimmed and clamped, the same torque on fasteners secures on shaft at installation.
It looks like a boring mill, so must be using the quill Z axis as a broach, like a lathe chucked part, cutter driven by carriage. Possibly, that era had a mechanism to run the quill in and out without rotating spindle?
However, can't imagine a spindle within a square quill, I believe the machine is a shaper.
An alternative would Z the table; but this is a floor machine, not table type. Floor machines are considered 'portable', they secure the column at the part, the 'floor' actually is a giant Tee slotted plate. Dialing in a part, isn't a couple handles like a Bridgeport.
Along with all that, the bore could have been done in a vertical lathe. The casting has been turned, those grooves ain't cast, an concentricity included. Biggest I've heard of was 33'; if man in picture is 5'5'', that's an 16' to 18' sheave.

Marv, how does one splice the ropes?

Sure beats having to match the individual rope lengths.
The "rope" is really a heavy, three strand string. There is only one join; the finished "belt" is a single loop. In order to get the loop size correct, it was formed with the rope in place on the model. In my younger days I built a lot of ship models so I was familiar with the splicing process but I expect one can find information on that on the web. Once spliced, the individual strands were reinforced with sewing thread because I didn't trust the cord's friction to handle the strain.
The whole process is a real exercise in frustration and fidgeting. I don't care to repeat it. Fortunately, if I did have to repeat it, I can now measure the existing one to get the loop size and not have to spice the new one on the model.
Animated knots has a whole section devoted to splices...

This one...

shows an animation of splicing two pieces of three strand rope, much like what was done on my minature rope drive engine.
Splicing-is fastening two Ends of a Rope together, with uncommon Slight-to execute which requires no ordinary Skill; as I can venture to say not one Seaman in twenty can perform it.
A Naval Repository, 1762
my wife is a manager at west marine, they had one guy that mad appointments to teach or do it for people. sadley he has passed ,I dont think any of the other salors that wprk in any of the local stores can do it. this guy was awesome. but he was in the Caribbean sailing and stepped on something, sepsis then stepped in.gone in about a week. so sad.
When I was a lad in my teens, 30+ years ago, I worked at an auto parts store. We sold a lot of parts to local farms and one of the things we would sell was 3" diameter rope (special order obviously) so they could use it to pull stuck equipment out during fall harvest season when it was muddy. We had an old retired Navy guy who would pick up the rope, we would toss it in his pickup for him and he would take it home to his shop and pull each end of the rope out of the truck and braid eyes in each end for clevises. He was probably 70-80 and could only handle so much of the rope, so we made sure he could easily get 8-10 feet of rope out of his truck and onto a workbench. He would bring it back in a couple of days and you couldn't even tell that it wasn't a "factory" end. Although I would bet they are done at the factory by hand as well, but they didn't offer it for these monster ropes. We would coil the rope onto a pallet, strap it down and deliver it to the farm.
He would come in when we were slow and teach us to tie knots. He would have to slow down so we could follow him and could tie most of them with his eyes closed. I still use a bowline all the time as it's the only one I can do quickly without having to look at my hands.
Edit: I just remembered him telling us that he could tie the knots with his eyes closed because he had to be able to do it in the dark or underwater with no visibility. He sure was a neat guy, very patient and had great stories.
yup thats like my old friend.
If anyone is truly interested in learning to tie knots, the good kind that you can also untie when necessary, you need to practice. Find some rope and search for instructions. There are lots of resources to learn. There is a big difference in ropes, there is twisted and braided. You can tie knots in either, but splicing is different for braided vs twisted rope.
The splicing mentioned in this thread is with twisted rope. If you want to splice braided rope, specific that in your search
If you can type the question (how to splice ropes), you only get 8,380,000 results. The first 10 should show you how it is done.
If you type (how to splice braided rope) you get 8,660,000 results.
I love to sail, rope and knots are you friend. Even for land lubbers, learning to properly use rope can be a life saver.
This is a good source of information from Samson Rope
The "long splice" is what should be used to splice to run on the pulleys.
my old friend did the braided ropes. possibly both.
