Hello, i thouht of a cool idea yesterday. Basically i plan to make a crossbow that shoots bb's at hopfully decent speeds. I have already built a cross bow and enjoy firing 30 gram bolts at decent speeds. I use a completely homemade cross bow, with a medium power, fiber glass bow. I plan on building a plunger and trigger, to act like a springer pellet gun, except ill use the bow, and sprinss to propel the plunger. I cant measure the draw but its pretty powerfull. I will use 5 grain homemade pellets, a piston chamber ratio of 1(barrel)/4(chamber). I think ill modify a bike pump for the chamber, with really THICK METAL. If it is strong enough, ill then DO some deiseling! Tell me what youy think and please give some advice. I cant take pictures yet, my parents set up my phone so i cant use the internet and send emails with links!

My intitial thoughts is it would be a highly inefficient, overly complicated way to shoot a BB. If you're inclined to pursue it for the fun of it, by all means, knock yourself out. They abandoned bow power a long time ago for a reason.

Your other comments rambled on something about bike pump chambers and thick metal and some dieseling.?.?

...and I assume you mean that the camera part of you phone is basically useless because the appropriate cell service to send them has been limited by your parents.

YEP, my parents are mean!

Actually jsr had a design like that for airsoft sorry no links it is guaranteed he will see this post and reply.
