This auger has had a bad lower bearing for years. Balls and cage toally gone.
Finally decided to replace it.
Screw gear pullers and set screws, I torched it all off.
Enjpy.

There you be.
Only thing I did wrong was cut the keyway 1/8" to long.
Only had a vise crip and reciprocating saw.
Chain is kinda stiff so I'll soak it in oil or replace it.
Then she'll be ready for service.
Thanks for watching.
What welding projects are you working on? Are you proud of something you built?
How about posting some pics so other welders can get some ideas?

Just a couple welders and a couple of big hammers and torches.
Men in dirty jeans built this country, while men in clean suits have destroyed it.

Looks about like a lot of the cooling tower / condenser fan stuff I get into. Hasn't seen grease since the day it was put in service! Nice work demo without destruction can be a fine line.
I have more questions than answers

Well done. I use similar tactics in bearing removal.
I didn't think to take pics, as no welding was involved, but on reflection I did use a cutting torch to remove the old bearings recently on a 1HP 3-phase motor. I washed them off the rotor shaft just as you did in the picture. The trick is to have a super-clean tip that will cut precisely, then wash the inner race to within a 32nd of an inch. This is enough disruption to easily slide the remains off without cutting all the way through and risking scarring the shaft. It's a great technique to practice, as even with the proper press, fixtures, and fitting, an old rusty shaft will damage itself in the bearing's removal.
Then, I got to use my favorite tactic... I dropped the whole rotating assembly in liquid nitrogen for five minutes or so, until the boiling stopped, then basically slid the new bearings on by hand, with a couple gentle taps on a shaft-sized socket to confirm they were fully seated. Call it a different definition of "cold pressed"...
