Who has adjusted their chain?

I don't see how that's possible (to keep them both at the same flats) especially when the wheel has been removed? Please educate me.

you remove the wheel by pulling the axle out....drop wheel down....roll wheel forward.....take chain off sprocket.....remove wheel without letting brake caliper fall down. Don't move the adjusters at all. If you take the adjusters off for some reason, then you have to square things up again....once. Then when adjusting after that, turn each screw the same number of flats.... Most adjustments need less than one full turn. The thread pitch is very precise and alignment will stay if you do the same thing to each side.

and before you tighten the axle after adjusting, jam a rag between chain and rear sprocket and turn the wheel to roll the rag in there tight so that the chain pulls both ends of the axle tight against the stops and you take any slop out of the axle adjustment parts and then tighten axle, remove rag and verify chain slack.
