Re: What's the diff ?
Quote:
My apologies if terminology is off, the boring head is mounted on spherical, mounts on the boring bar supports. The last pic kinda shows how the bearing cages are rounded. The machine clamps on with the same curved socket so even if bar isn't true in the bearing support, the drive still connects. All bolted, no electro magnets. I'll get more specs and pics......I'm still trying to figure out how the machinist is going to fit a 9ft bar in the back frame with cab still installed? |

Re: What's the diff ?
Thanks for the info. Wondered if you welded up the bore so you could re-bore it and use the same size bearings.

Re: What's the diff ?
Got some more pics and a couple vids today.
First pic is showing top front frame bore being welded. That's a 10" diameter bore , 8" thiick ! Meanwhile, welder is repairing cracks and cutting out and replacing a cracked fishplate. Machinist managed to get a 8ft bar in between rear frame bores but a very tricky process. Had to pre install 2 bearing blocks then feed shaft through bottom bore then up through top. Add the 2 end blocks and get things all lined up. Due to tight space under cab the 8 ft bar is not long enough so after everything was set up he managed to have enough space to remove the long bar and then do each set of bores with a short bar. If I wasn't a mechanic, I'd love to do this machining work. This pic he's just setting up the welder which anchors to the rod seen. He takes a cut, then welds, then cuts again to finished size. https://youtu.be/93cjfZfTaDU https://youtu.be/HA6GqR6cBho |

Re: What's the diff ?
Cool stuff Mario. I need a boring machine to clean up the boom pivots on my mini excavator. I think that one might be a bit too large though.
