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.

Had this problem at most of the food processing facilities I visited, but I needed to document what was going on so the design team could understand both existing conditions and the client’s expectations. Usually was allowed to take photos but had to have them reviewed before I left.

Field machining & millwright work is always interesting & usually a challenge: looks good.
