If you can unscrew the forward side plate screw and remove the cylinder, it is a piece of cake. The worst part is cleaning the heavy oil out when you're thru. All you need is a vice and piece of leather to hold the cylinder, a chamber finishing reamer with a T bar attached, and cutting oil. Turn the reamer clockwise and never reverse the direction. Clean the reamer after each chamber, and more often if you are removing a lot of metal. There is a shoulder on the reamer to let you know when you're done. It will start turning freely. Clean the cylinder as you normally would and reinstall.
