That is NOT the point of slotting the hammer.
You slot the hammer so that the bolt can recock with the hammer but the hammer can stay cocked when the bolt gets held in a closed position. Vike's Complete Guide to Building a Spimmy | Everything you wanted to know about building a Spyder/Intimidator hybrid paintball marker
Basically the same deal for slotting the hammer, just make sure you attach the pump arm/s to the bolt and not the hammer.
