I have some guns that lockup tight as a drum, some that have a little play in all cylinders some guns that have some play in a couple cylinders and the rest are tight. What causes this? Timing is good on all of them.

Allglock is correct and it is extremely rare that each and every cylinder will be precisely identical. When the trigger is pulled, even the charge holes with a slight amount of play should lock up tight by virtue of the hand pushing on the star wheel. A small amount of play is considered normal and does not affect the functioning of the revolver. An excessive amount would make a difference though.
I have fit new cylinders to revolvers and it is difficult to make them all the same. I just went very very slowly with an extra fine Arkansas stone and after an hour or so got it as good as can be. Actually as good or better than the Factory usually gets them. It is not a job I look forward to doing often.
Remember, these are assembly line produced revolvers, NOT hand made to sheer perfection as we would all like. Sometimes I'm amazed that they come out as good as they do!

I wish I had the tool that cuts the extractor star! I saw it in use at S&W, on a youtube video.

I was just going to ask about this . On a 617-4 10 shot 3 consecutive cylinders do not quite lock -up on a timing check. Leading at the forcing cone is normal but I wonder how it effects accuracy ? I wonder also if S&W would repair this under warranty ??Should I be concerned over this? It will only get worse with wear.

As long as lock-up is tight just a nano-second before the hammer falls to detonate the primer, accuracy should not be affected. When the trigger is pulled all the way to the rear the hand moves up a bit higher to tighten everything up. As long as that is what is happening, you are fine.

If your revolver has multiple cylinders it is a rare bird, indeed. It has but one cylinder, with multiple chambers.
There is some slight cylinder play at each chamber, and that is as it should be. Minor variations in play between chambers is inconsequential.

Cylinder chambers 5 do it on one side which means to me the star on the extractor on one side is not even or centered if you will. S&W still has new 10 shot cylinders so I will shoot it for a while more and send it off for a new cylinder/hand?? - my dime I suppose but maybe they will pick-up shipping ??
