Hi

Just wondering does anyone know how to set a cross bow Prod - is there a way of doing this - in regard to depth and angle -
Basically I made a complete crossbow But broke my homemade bamboo prod while on the tiller - so Bought a 27" tawainese one 160lb that several people seem to use . I have googled heaps and found they have 3-3.5" brace and 11-12" max draw length ..

i made a modern style solid stock and will mount the prod in a square hole and then maybe a bolt from the front or a wedge covered in a metal plate .

Most people set prods in at 6˚ but i can find no information on how deep should it be in the stock and exact angle - is there a way to work this out ?
Thanks Mark

Maybe Del will chime in. He's made a few xbows.

I try to set 'em up so that when you look along the string at brace the string is in a straight line, not bending up onto the track from the tips.
Lots of ways to achieve this. Tilt the prod or make it with the limbs sweeping up a tad.

Alternatively set up the angle by drawing a straight line from about half way along the track to the top edge of the prod and maount the prod at right angles to that.
It's all a bit of a compromise.

Hi Del

Thanks for the reply - so basically a good gauge is half way along the track to top of the prod ? not sure i follow exactly as i didn't cut any hole yet for the prod - as mentioned my prod will be in the middle of the stock not stuck on the end - so not sure how to do that unless i just use half the draw length stick the prod on the end temporally and do that ??
so there is no set angle ?
how about depth of the prod - exact middle of stock or closer to the top ? i would have thought closer to top but need enough wood for strength But is there a correct method or is it all just guessing ?

Thanks Mark

Mount the prod as high as you can without fouling the fletchings... that's why most medieval/primitive crossbows only used 2 fletch! :)
Sounds like you have the right idea.
