If by "out of time" you mean that pulling the trigger in double action does not advance the cylinder quite far enough to lock up, you have insufficient 'follow up'. You don't need a hand.
All you need is to gently peen (tap) the tooth on the star ratchet that is contacted by the hand for the chamber at 12 o'clock that is not locking up. Use a flat tip punch and a very small hammer. It's a very simple fix for a common indication of wear. You can tap all 5 teeth since they all have the same amount of wear.

I'm nervous about going too far, not knowing how far is to far until I go too far...The the tooth for the OOT chamber needs another tap or two.
You really can't go too far because you can always tap it back.
Tap once and try it. You're not taking the cylinder out of the gun to tap it, right?
