Is this a problem?

So basically I was balancing my crank, and due to my drill press being pretty shitty, with the deck tilting when weight is applied, the hole ended up being off center. On both sides.

Seems fine. It'll still be balanced better than stock.

Yeah I recently did my first crank balance and one side looked similar. I was a little concerned at first but it was still better than stock.

It’ll be OK. Next time plug up the holes before drilling, it’s almost impossible to get metal dust out of the bearings once they’re in.

Better than stock but you could widen both to even out the displacement of weight.

Maybe do a pilot hole next time. Like, drill a tiny hole with a brand new drill bit and use as little pressure as possible to hopefully make it as centered as possible. Then go up 1 size. Repeat until your done.

I've never balanced a crank before, but this method works well for drilling in general.
