I made a custom hammer to fit my air tube with minimum clearance (.002 under airtube bore). Below is my first string with the new hammer and SSG. I'm really happy with the curve with this setup. I used to get some erratic FPS values up and down the curve. This one seems much smoother. If I extend the string to include FPS values down to 921, I can get a full 24 shots, with a 3.76 ES%, consuming 944 lbs of air.
The guide bolt is 1/4 x 28 and the thru hole for the guide bolt is reamed .001 over. The spring bore is bored 7/16 to more closely match the diameter of my spring. Cocking is smooth. Can't wait to setup a hunting tune with the JSB heavies.
Here's some pics of the creation of the hammer.
The small hole in the counter bore mates with a 'tang' on the end of the spring. A matching hole in the guide bolt nut holds the other end of the spring in the same manner. This allows you to adjust the spring tension without needing a set screw to keep the nut from turning. In my original hammer, I had inserted a nylon spacer (Marauder forum 22synrodn style) in the bottom of the hammer and drilled that. I added that length to arrive at the new counterbore depth, eliminating the nylon spacer.
