I made up a simple notch lock crossbow along the lines of this:

I made a linen backed Red Oak prod from a Home depot 1X2 which gave me about a 75 lb pull. An earlier heavier prod broke. I replaced it with a cheap 150# fibreglas prod. Much faster! I can see why composite prods took over from wood prods.
I am not too happy with the trigger. Slow, heavy, creepy. The long tickler flexes too much. Grease helps the push-pin a bit.
Does the diameter of the push pin make a difference? Would a larger/smaller pin have less friction?
I made up the string with artificial sinew (Dacron) to the same diameter (7/16")as the bolt diameter, which size seemed to be medieval practice. My push pin is a bit smaller, about 5/16".
Is the heavier trigger just a result of a more powerful prod?
