forgive me if this is an elementary question, but what keeps the barrel from turning when you tighten the barrel ring/nut collar on the gun.
if the barrel turns, it changes the cylinder gap, so?
thank you,
Roger that.

Yeah it’s a pain in the butt. Some people find using a rubber glove or something to hold onto the cylinder end of the barrel helps.
I just do trial and error. I see how much it rotates and take that into account when I’m setting the gap.

Roger, I open the cylinder and hold my thumb against the end of the barrel while tightening the nut. This usually works. If not then I do what Andrew1220 said.

Do you find you have to attempt getting gap set a couple times, trial and error?
reminds me of adjusting the valves on a Volkswagen bug.
whats the cylinder gap anyway, about .006?
thanks

Funny,
that is the exhaust valve clearance for air cooled volkswagens.

What Snake-eye said about holding the forcing cone with your thumb. Not always necessary. I clean and oil the threads on barrel, nutand frame when I get a new/old Dan. That may make it turn when tightened. Maybe not. Remember, snug, not tight.
Once you get a feel for .006 or .004 you can hold the gun up to a light and eyeball the gap. That way you are sure you didn't push the dedent ball in. You can also cycle the action while holding it to the light to detect the proudest chamber if the cylinder is not perpendicular. Much faster. I prefer an automotive set of feeler guages to learn. Much easier to hold and you have all the different thicknesses.

Ole dog,
thank you, I smell what your cookin sir. Made perfect sense.
so what happens if the detent ball is depressed a little?
is it ok to have minimal cylinder gap without having binding or cylinder drag when cycling? Just wondering
thanks

When you push the shim in it depresses the dedent ball and you get a smaller gap than you intended. The small frame 357 cylinder expands when hot. After several cylinder loads the cylinder can rub against the forcing cone. Large frame and Supermags don't do that. Also, powder residue builds up on the face of the cylinder during a range session. Some cylinders have a less than perpendicular face and the proudest chamber can rub if the gap is too small. Those are the reasons the factory spec is .006. I prefer .004 or even .003 if the cylinder face is even. It can still bind from expansion and residue though. Take your tool with you when you go shooting in case it binds. Wipe the face of the cylinder with a rag every several loadings. Be sure to unload before fixing the barrel gap. Or set it at .006 and you won't have a binding problem. You may have a spitting powder problem though. Lol.
