On another thread, dfariswheel discussed endshake, the condition in a revolver of having excess lateral (horizontal) play in the cylinder.
He then gave these instructions for repair of Smith & Wesson revolvers only. They refer only to S&W, not Colt.
Also, is there a book that explains simple gunsmithing chores like this?
As it stands, I'm more likely to have a gunsmith fix it, unless someone encourages me.
Thanks for any replies!

With the gun UN-COCKED and the action at rest gently push the cylinder forward and hold it there.
Use an automotive feeler gage to gage the barrel/cylinder gap.
Push the cylinder to the rear and hold it while you gage it again.
Subtract one measurement from the other and that's how much cylinder end shake you have.

My question is, is this procedure something only a qualified gunsmith should do, or can it be done by an end user (pun not intended...well, maybe a little)? If a user can do it, what tools, exactly, would he need. And if it's something only a gunsmith can do, what's a fair price?For S&W revolvers, the end shake cannot be over 0.006".
Colt's are much tighter specs with the maximum allowed being 0.003".
S&W revolvers can have end shake corrected by three methods.
1. Trim the rear of the cylinder yoke to true it up, then install greased hardened stainless bearings.
2. Stretch the yoke barrel by inserting a hardened steel stud to act as a support, then gently peen the yoke barrel to stretch it.
3. Use a special tool made from a tubing cutter to stretch the yoke barrel.
The tubing cutter has the hardened cutting wheel rounded off to a round, non-cutting edge. The tool is used on the rear of the yoke barrel. Instead of cutting a groove, the tool rolls a round groove in the barrel, stretching it.
