    According to the customer, the crushed bars do have a very distinct sound along with their "case hardened" skin to reduce denting. I was a Millwright for 40 years and the constant ringing in my ears would preclude me from being able to recognize any subtle sound, musical or otherwise.

    [QUOTE=tdmidget;3445928] Obviously good for some bucks on your end but I can't see why any one uses it ./QUOTE]

    PS....forgot the most important reason. If the material is dense, you can carry a lot more because with a lugger you get more weight over the front axle(s). If you carry skeletons (from laser or plasma cutters) or chips, a roll off is best because you max out on volume - there's a lot of air in the box. But other scrap like from stamping can be really dense. With current requirements you can get about 20 tons on a lugger, maybe 10-12 on a roll off. The above truck is around 12, but we also make a slider than slides the lugger forward. It can carry 20.

    Show and tell for this week.....another truck body, a conveyor, cranes, rebuild of a transfer car, wet air scrubber and self dump hoppers.

    crane getting the hoist and electricals installed



    Another crane fit and ready for subarc welding



    Wet air scrubber and hambone project manager



    self dump hoppers



    Design build conveyor for ore processing at a mine



    Another truck body...chassis arrives next week



    60 ton transfer cart rebuild...I want to get into making these

    Making crankshafts. Dual centers on each end so we can turn and grind each journal between centers. Then wire Edm off each end. Finished grinding after heat treat. Finished part on right side of first picture with end slug that had been removed.

    alskdjfhg,


    Would you get thrown in prison if you told us what that thing is? Looks like a giant food processor.

    Standard de-bladed gas turbine rotor.

    I work more with process steam equipment, but I think this is a W501, probably about 200MW output.

    With the blades on it, its absolutely gorgeous. And amazingly expensive.

    Yep, Thing of beauty till some guy scores it during install then has to be welded up with Stellite then field machined. That's an uneasy feeling up on the scaffolding with a 200 ton rotor spinning at 30 rpm's and you have nowhere to run because OSHA says you have to be tied off. Not to mention doing this in the wintertime with the breeze coming off the blades. It's not easy telling the boss you screwed up a $10M turbine and an $8M case.

    That's a low pressure Bi flow steam rotor.

    I posed a pic of a gas turbine rotor, single grain forgings for the blades, turbine blades with internal cooling passages ect, way more exotic materials. Very different.

    Done alot more machine work on the steam stuff, cut off shaft ends, cut off whole wheels, subarc weld rebuild and then the machine and cut the roots.

    Steam is wayyyy more forgiving than gas turbine. Much more you can repair with steam stuff.

    Most of the stuff we did was Nuke and Fossil turbines so that was limited to steam. I only got to tinker with big gas turbines when someone nicked a bearing surface during install. Either way steam or gas, I hope I never machine Stellite welds again.

    That is one big ass turbine shaft. I'm guessing your not allowed to disclose the application?

    Application is nothing special, most of these midsized gas turbines are power related. Just a big a dumb turbine turning a generator to make magic pixies.

    We cut stellite welds all the time, nothing crazy, got an insert to do it.
