  1. I don't know what's going on, but that guy sure doesn't have enough protective gear on.

  2. I would say he's thermally expanding a RR "tire" before pushing it onto the wheel...hint was the other RR wheel in the background...

  3. As I understand it, the outer ring is hardened. When replacement is needed they heat it to expand the ring and remove.

    1. from my misspent youth I can say that's not so. the tire is dead soft so that the tire wears instead of the rails. easier to renew the tire on the wheel than the rails out on the curves. the shop guys hate it when the engineers use a lot of sand going up the hill. and flat spotting a steel tire by locking the wheel downhill can get very...noisy. so, sand.
      but yeah, get it hot enough and it will fall off the wheel or push on as the case might be.

  5. The engineer made a deal with the devil to hunt demons, but only near railroad tracks.

    1. It would be better if it was on a motorcycle. Maybe someone should make a movie about that.

  7. That's what I like about this place. A lot of guys know a lot of stuff about a lot of things. I was going to comment about it, but you guys already know! Also I've seen "Baby gets new shoes". Great vid!

  9. Singing in Johnny Cash's voice: "I fell in to a burnin' ring of fire. . ."

  10. Read about composite wheels for passenger coaches here: https://en.wikipedia.org/wiki/Paper_car_wheel

    Hint: in addition to the fact that the wheels were made of multiple metal pieces, they also incorporated compressed or laminated paper. The flanged rims or tires for these special wheels were bolted on. Probably wouldn't have wanted to use fire to mount those!

  11. You'll see the same thing putting a metal tire on a wooden wagon wheel

  12. Had the good fortune of catching the Big Boy 4014 going through a nearby community about a year ago. If you can I highly recommend it. The only thing missing was the coal and belching that beautiful black smoke. They were burning I am sure some kind of environmentally safe oil. Fucktards always ruin a good thing.

  13. Do the same thing when you're mounting a new ring gear on the flywheel of an old car. Old 6v starters didn't have very powerful solenoids to shift the pinon gear to engage the starter. The ring gears would get eaten away and then the starter pinon wouldn't engage to turn the motor over at all. So: Cold chisel the old ring gear off. Re-surface the flywheel (preparing it for your new clutch), into the freezer. Ring gear into the oven. Put them together for a tight tight interference fit once they return to room temperature.
