Dragline Rebuild

[modelman]

I have some work done on the swing assembly. I got the holes drilled and reamed so that is the critical part. I still have a little milling to do on the plates and another set-up on the other-6-bushings.-

I probably didn't save any work by using the square drive parts. I tried running the square shafts in nylon and brass bushings but the drag was way to much and caused the motor to lag and draw to much current. I had to get a 4-jaw chuck and turn round ends on the .125" shafts and now they work really smooth. This is the gears I have to pack into these frames to get the pinion speed down to 9-RPM.-

I am still waiting on the pinion and swing gear and also a 1/4" shaft for the pinion. I'm getting closer.
