My Bob’s Knob’s finally arrived and I’m installing them today and I know to install them one at a time but how do I know when to stop screwing them in?

Glad you are aware to do one at a time!.  I would suggest screwing the first one in just enough to locate it well, the further you screw it in the further away the next one becomes.  Once all three are located just try and advance them equally.  🙂

Just screw in the first one until you feel the screw making contact but no more. Repeat this for the other two then once you have done this with all three give each of them a tiny 1/8-1/16th turn feeling resistance. Then check the collimation. If done this way it won’t be far off if at all. Good luck.

What scope is it, and which end?

It’s a Celestron 9.25” evolution

Okay thanks, that’s what I was thinking I should do but I wasn’t entirely sure so I decided to ask here first.

Yep - do one at a time: remove one old bolt and replace with one of Bob's, then repeat. Don't take two or three out at once. That way the collimation won't change much.
