how do you get this annoying bearing out of the sierra upright. been at it for like 2 days now

I did it with a hammer and a chisel. You can also take a mig welder and put some welds on the bearing, that will make them looser.

hit it with a drift at 12/3/6/9 o clock positions repeatedly and eventually it comes down. Getting it moving is the hardest bit.

Careful you're not hitting the lip thats part of the upright though.

Yeah, weld it.
Knock the inner races & balls out & clean the grease off, weld around the inside of the outer race, 2 or 3 runs all the way round is plenty.
Just make sure the welder is'nt set so high it burns right through & gets hold of the upright & that you dont get right up to the edge & weld the race to the upright at the edge.
As the weld cools it contracts & pulls the race in too, mabye only a few thou but it will almost drop out or push out with your fingers once cold.
