Line boring

[Greywynd]

Due to the locations I work, often there are rules about phone and camera use. However right now I’m at a spot I can share a little.

I work as a field machinist, primarily repairing large dirt/mining equipment. Currently working on a track frame rebuild. Tonight’s job is to finish the bearing bores on the drive end of the frame.

23 and 5/8” diameter, +/- .001.

Mark, what is the dimension you are cutting? another of those 30" jobs?

Ignore this, just saw it in your post

I finished it last night, guys on day shift did the teardown. Seems I was about 3-4 tenths undersize. Nothing a swipe with a die grinder and a flap wheel won’t fix.

The inner face didn’t need machined for those wondering.

Just turn the temperature up a degree or two.

Definitely another option. Or leave the bearing cartridges outside overnight.

Better than 3-4 tenths oversize after all that work!

Respect.

Nice job!
That looks like a climax machine to me. Ive ran thier flange facers but never one of thier line bore set ups.

Very cool. I always love seeing line boring setups in the field.

That one is a Climax setup. Our larger 5” bar setup is a shop made Climax knockoff. Should have that one setup and running this summer sometime.

I always take them, it’s a matter if I can share them or not.
