Never mind. I got it.
This was my first attempt at cleaning this gun, which is somewhat of a challenge for this spatially blind guy. I followed the owner's manual and the info on Chris' excellent FAQ site and all worked out well.
Brownell's 1/16 inch punch isn't as solid as I would like and I had misplaced RJ's "Stop Stick" so had to make do with a wooden chopstick and the end of a small screw driver. Definitely could use 3 hands.
