It uses a laminated wood and fiberglass prod 157# @12" power stroke mounted on a walnut tiller
It may not be a historically correct medieval crossbow, but that is not what I was trying to achieve. I wanted a medieval "style" crossbow to use for hunting. So it has some variations such as the stirrup is independent of the binding for the prod.
This is done for two reasons:
cocking the crossbow puts no strain on the bindings holding the prod and the stirrup is bolted on with two lag bolts which strengthen the forend of the tiller.
