Default Making a crankshaft

Not sure if boss charges a premium for this lathe or not. But he had figured it would take me a full day plus to do this rod. I did it in just over half a day. I was thinking that it probably should be charged and extra premium, since we usually only use it 1-2 times a year.

This year I set a goal to use it once a month. I’m putting the date on the machine each time I use it. I think I’ve used it 6 times this year so far. For some reason, my co-machinist does not want to use it, if possible.

Basically, spending time cleaning it up, so I can read the feed change tags, and downloading a manual for it, so I learned the little features of it has paid off in learning to use it efficiently.

The old guys used to have to power it off, coast to a stop, then reverse the motor to return the carriage when threading.

I learned that when you turn on the separate Quick traverse / coolant motor, I can thread to when I want to stop, turn in the cross slide to remove thread tool from the cut, and pull up on quick transverse lever and the carriage will move back to wherever I want very quickly, and then will drop back into the gear to start threading the next pass again.

This was the first time I ever used the turret slide, using the # 6 Morse taper for drilling the hole up to 2-1/2” diameter ( largest drill I have at work) I still haven’t figured out how to rotated the turret to other positions yet, not that I really need to, I just want to see the whole machine operating like it can.

We have talked about making a crane and attaching it to one of the turrets spots so I can more easily load bigger cylinders into the lathe from the front side so I don’t need to try to use the fork lift .
I have bosses permission to get it built someday, when it slows down.
