Well impressed, wish I could work half as fast! There are 2 main types of all-wood trigger mechanisms, child's-play to make.
1. Push-pin, like the one I posted on the first page, a slot across the stock, a hole drilled through and a slot milled out underneath as the pin rides on a comb - make the pin square based and it won't drop out when you tip the bow upside down,
2. lever-arm lifting the string put of a groove - this one is my test rig, very rough and ready but deals with laths over 100lb comfortably
