explaining 3 different crossbow trigger designs, this is the second trigger video I have done like and comment if you have any trigger ideas. #archery #archerycustoms
Thank you for this and previous video and explanation! I was looking for the simplest mechanism and your one part type from this and previous video are the best!
If you study mechanism or linkages (mechanical engineering) the basic problem with these types of designs is that every piece is rotating around an axis. This works fine when you have metal parts but if you are using wooden or plastic parts, the stress can break the part. Wood, plastic, etc. are far better at handing compression and extension forces over shearing or rotational forces, so the best designs make using these types of materials make use of these properties. I've made different styles of two and three piece triggers for a while but if I am using wood or plastic most of the parts will move in a straight line rather than rotating around an axis. So while the trigger system is a bit more complex with multiple springs and more surrounding parts, it can also support a heavier draw reliably despite the materials it is constructed with.
I agree that those are better materials to use but in this case I am using plywood and it is plenty strong for the application. Unlike plain wood that relies on grain direction for strength plywood is engineered to eliminate this fault. I have shot my 3 piece trigger at least 1000 times and it's holding up great 🙂
