Hi everyone, Here is a picture describing my problem.. http://www.pbase.com/image/20344544 Basically, it's the firing mechanism for a toygun. When the trigger is pulled, the hammer flies forward and hits the firing pin. The firing pin then flies forward and hits the button. I came up with a better design but i need to verify if it's actually better or not. Also, would like some suggestions on even better designs. LIMITATIONS: Basically, the position of the hammer's axis of rotation cannot be modified. Nor can the position of the firing pin or the button. The shape of the hammer and the shape of the firing pin can be modified. The shape of the button cannot. thanks for the help!!
