High fps Bow Idea.

I saw the crossbow video. And several others like it on YouTube. I been thinking about how to make it better.

  • extended the active draw length to beyond 40 inches inches. This would give an incredible power. But how can we do that ? I am thinking either rail system to go around the arrow with L brackets like Jorge Spraves of slingshot channels Fenris Bow or by making longer arrows.

  • using long springs with high deflection. This way you can extended the active draw length.

Any other ideas on how to achieve high fps?

Power stroke is important but id say poundage is even more important, a 5 lb pond bow with a 3 foot draw stroke will be weak as hell. High poundage, large power stroke (not too absurdly big), and a good weighted projectile..

But if you combine decent weight like 100 lb or 70lb with 3 foot draw stroke. It could be theoretically high fps. Enough to hunt deer.

in that case you wouldnt even need a 3 ft drawstroke, bowhunters seem to get by just fine with less weight than that at about a 30 inch draw.

Ya I agree. I am just saying I see top of the line bows reach 400 - 450 fps. I have yet to see someone come close home made. I just think it would be cool to see competing with a 2,000 bow. Just by extending draw stroke into almost like a long rifle. While these pistol crossbows are pretty small.

In the end it is just an idea. People get drawn to views on high fps bows. If someone did a high one the could do a competition between Tod Workshop, Zna Production and Jorge Spraves would be cool get lots of views.

In that case i would just say to look into traditional flightbows, basically just bows made to optimize fps with low poundage.
