Stiff cylinder turn on Redhawk

[Lee Q. Loader]

The following is a quote from an older thread on THR:

A tool has been available for many years now from Brownells to clean the groove that the spring loaded ball rides inside the cylinder bore. This is part of the Ruger DA design. If the carbon buildup in that groove is not removed occasionally the cylinder will start to bind. On a heavily used competition gun this is a regular part of maintenance. For most shooters it is rarely a problem. When my wife started competing (and practicing heavily) with her GP I had no choice but to buy the tool and use it. Some powders are worse than others for carbon buildup. One of the best solvents I have found for dissolving carbon is Dexron ATF (and it also is a very fine lube).

I've tried to find the above noted tool to no avail. Mostly because I'm not really sure what I'm looking for. I've got a really bad stiff cylinder turn even when the revolver is cool and the cylinder is open it is very stiff to turn.
Could someone please help me find this tool?
Thanks

Maybe these videos will help. I found these after reading your post.
Disassembly of the cylinder and crane.


This video shows the ejector removal. He makes his own bit (special tool)


This looks like the bit you need from Brownells.

I looked this up for my own reasons too. I wanted to know how to disassemble my GP100.

Mine was stiff on my SW 25 the last outing. I cleaned and oiled it. Much better then.

Thanks so much!

I've cleaned it several times and oiled it. Probably too much oil. I think it's carbon build up.
