I'm designing a printed stringer that uses a sled rather than direct string contact, and I'm trying to decide on whether the trigger should pull or push on the catch mech to release. In a direct contact stringer, the catch mech just pushes the string directly upward, so this is all new to me.
The sled is already pushing forward against the catch, so a pulling trigger would press the catch harder into the sled and pull it back further before releasing. A pushing trigger would instead move in the same direction as the string tension, temporarily reducing the load on the catch before releasing.
Is there a significant difference between these two methods? Should I just use a pivoting catch instead? Bear in mind that stringer springloads can get a lot, lot heavier than springers if desired, so I'm thinking in terms of what will be best for these printed parts as they produce constant lateral friction against each other.
Good to see the Sportsman getting some recognition. I hadn't considered a sealed breech, but 140 fps on the stock spring is nothing to sneeze at. Are there any printed options for mag adapters or something similar?
