Only 12 easy steps lol. Pakistan is obviously a poor country and so different than American production. I think it’s interesting to watch this 4 Star factory machine these V6 or 3 cylinder crankshafts with manual labor.

Love the state of the art coolant application system. Wow.

What was the deal with the hammer off and on?

No arms or other limbs were lost during the making of this video. Quality goes in before the name goes on.. The **** Hammer gets it.

that is how our administration wants us to live and work.

Straightening. They were pretty good at it too. I built heavy driveshafts for a while in college. Some guys were really good at that method of straightening.

Years ago it was thought that India would pass China as the world's manufacturing power. China remains with the stranglehold.

The crate says "made in Pakistan".

SOP to indicate a part in a 4 jaw.

This was a pretty cool video to me since I have been in the production machining world for over 30 years. We used to do many operations that weren't much different than what you were seeing. Lots of fixturing and drill bushings. Since I took over the shop we have moved everything on to CNC machines now. The bad thing is that I'm the only manual machinist left in the shop.

Some of you may not want to hear this but I bet if you went to the Eagle or Scat factory in China the roughing process wouldn't be a whole lot different than what you saw on this video. LOL

With the chip shortages going on, it makes you wonder if we could not repair cnc machines, would we have enough skilled machinists to actually machine without those automated controls?

There's more of us than them. Wait a minute, no there's not.

You've already admitted you'd bend over for a track official without peep.

You'd make administration officials a sandwich when they're done with ya.

You ain't fooling me none.

The Eagle Factory is nicer than I thought it was.

Easy answer. NO! One of my best friends owns a machine shop and they do lots of repair/re-build type work of stuff that parts can no longer be bought. Large gearboxes, rollers for metal and or paper manufacturing, etc.... He can't find anywhere near enough machinists to do the work he could have. A great deal of that pretty much has to be done manually.

It's funny you mention chips. I have machines that if the main board goes out I have to get a new control for them because they say they can't get parts for those boards. $10,000 retrofit.

As the discussion moves to the Erosion of skilled labor, in particular machinist, as opposed to CNC operators, this reminds me of what I saw in Power Plant operations over 30 years as a Controls Engineer.
As that industry moves forward, with advanced automation and controls, the humans skills fade into the sunset. 40 years ago, a skilled operator could recover from a system upset and using manually control. Now Controls are so automated, the operators job in an upset is watch the Control System and try and respond to a flood of alarms. From a process control side this is good as most problems are human error. But of course the operators process skills shrink to minimal hands on ability, just like a modern machinist I’d guess.
Wait till AI is entrenched and the system ***** slaps an operator trying to do something. lol

Mike Rowe has been working to correct the loss of skilled workers for a long time.

Them guys are gonna pick there nose and blow black chunks from there lungs for yrs. They work vary hard no denying it.

No matter the building condition, abandoned 100 year old building it looks like. These guys can handle a lathe, a lost art in America is my guess. We have a manual Bridgeport and I enjoy an afternoon making a Powerglide valve a Double dump Pro-Brake. Next up is I want to make a low gear and high gear brake valve body. ?? Need some sketches from my man at TSR first though ;-)

you should see how a motorcross/atv/motorcycle crank is done.

Crude is a word that comes to mind but theres really no other way to do it.

Precision? LOL.

I did a bunch of them in the hayday. The bigger ones (600cc+ single cyl) required every bit of the 50 ton press to get the big end pin out. Then 50 ton to get the new one in-as square as possible by eyeballing. To true the halves, big copper hammer and whack it. Set it back on the blocks and check it with dial indicators. The funny thing, you could get it to zero, install it (properly), run the engine 5 minutes, pull the crank back out and put it on the stand again to find it .005" off. So after a few hundred cranks pressed, I quit getting them to zero. Spec was .002 on the smaller ones which I tried to stick to but honestly, on my own stuff if they were .020" it was fine. Never once had one come back either.

The ones I hated were multi-cylinder usually 2 strokes. most of them had to be welded or they'd come apart. I learned this from a guy who lived in Florida who was retiring and sold me some of his tooling. The welding might or might not affect how true it runs. If we got lucky they'd only be .005" off. Thankfully I didn't do too many of them as normally when the customer brought a bike in with that kind of engine, and the crank needed work, by the time we saw them the engine was totally expired, generally speaking the owners weren't willing to put the money into them. I threw away (scrapped) at least 4 RZ350's that I can remember, I kept one and sold it for parts for $150. I wish I'd have kept them. Cool bikes.
