i wanted to try to make a SUPER heavy bow that i would brace with my feet and pull back with both arms, what would be the best dimensions for something in the 250-300lb range at 36inches, i know this sounds big, but thats what im going for, and i feel that if i can pull 120+ regular, this shouldn't be too big of an undertaking, while tillering i might take it down to 250 tough. any help and suggestions will be welcome ;D, including size recommendations, wood types and so on
thanks

Well now i pose the question as to how you would hold the bow. It aint like ya got thumbs on your feet to keep the thing from flying out of ur grasp once you release?...
But sounds cool, I'd like to see it done.
-
You'd have to make it quite long to keep the string angle down, and not pinch your hands. Either that or use a knock loop with some kind of release... although I'm not sure if commercial releases are safe to use for 250 lbs...
That would be cool to try though. You could launch broomsticks with it that could punch through walls :)

what im planing on is 8ft long, and ill have straps around me feet holding it there, what im worried about are my fingers, i think i might hake a handle type of thing out of some old anchor rope i have >:D, who knows, with a regular arrow, i could hunt elephants from ym back yard, just angle high and hope the military dosnt shoot it down while crossing the ocean >:D

Just curious what the point of such a contraption is ???

it would make more sense if you knew me in person.... you see i like being REALLY excessive and i figured this would be a way to get over the whole problem of one arm holding it and one pulling, i know my legs can hold easily over 350lbs( im not trying to brag at all, im trying to help people understand), and i bet i can hold 120+ per arm the way i am thinking, so i figured, why not go for it, and when i start working ill try to show the progress and hopefully eventually a video on youtube ;D
thanks

Foot bows aren't all that innovative, they've been shooting competitive flight bows with feet since way back in the black and white film days.
Guys that build bows to hunt deer in the woods scratch their heads at the nutjobs that tinker away in their garage building something that is going to blow after only 15-25 shots thru it out on the Bonneville Salt Flats. But ultimately it's those nutjobs that really dialed in some serious data on efficiency, low drag, high speed, etc that we use today in tweeking our hunting bows for best cast and accuracy. Two sides of the same coin.
Lemme know when you got that bow done, kid. I got some spare cedar fenceposts I can fletch for ya. Sounds like what you are building is the bowyers version of the Armalite .50 BMG!

i know its not innovative, but i defiantly fall into that nut job category, but this thing i am going to make to last ;D, and about the fence posts, if i cant get any railroad ties ill pm you ;D
this is more what i was aiming for, and those people that hunt and scratch their heads at this will want one after they realize i can hunt in Africa from my porch in RI from it >:D

go big or go home, or if you have to, go somewhere in between :P

arms wont be a problem , i think you'll be using your back for most of the work. a good heavy pair of leather gloves would protect your hands from the cable youre gonna need for a string. a regular arrow wont give you the strength your gonna need to shoot off of such a heavy bow. gonna have to be at least a 5/8th shaft just so the nock fits on the string. very cool cant wait to see how you make out.

Invest in a good cup too. :o

You will be able to string a bow of 250 with a stringer, I would think a hickory back tapered ipe core and a hickory belly would work, I have that combination on the tiller at the minute showing 90 at 14" just got it off the long string

that sounds like quit a bow, why hickory as a belly? i thought it was just good for tension

-I've used the 220#@30" wytch elm bow as a foot bow, and it's a lot of fun. Actually, you won't use your arms much. You hold the string with both hands while your legs are bent, and then just straighten out your legs. Remember to tie the bow to your feet.
It was not at all difficult, and it wasn't any hard to "pull" (push?) the bow at all. I could have shot a much heavier bow this way. What was hard, was aiming and not overdrawing the bow, as it's hard to see where the arrow stops while lying on the ground like that.
I guess if you make a bow from osage, yew, wytch elm etc., you can easily make a 250- 300#'er if you just make it long and wide enough. I guess if I were going for 300#, I would have made a w/d 7cm/5 cm at handle, 230cm long ELB style bow from wytch elm. (Hmm, maybe I will..?) I'd also give it a thorough heat treating on the belly.
-I also guess osage would be perfect for such a project

i am unfortunately limited to what i have, i just started building bows in the last few months and there has been a fewfeet of snow the entire winter untill recently, so i think ill have to make it from boards ipe and hickory i think right now, my plans are right now 8ft long, i am going to try for a 36in draw( the arrow will be more of a spear ;D) i might be able to access some osage, but i'm not sure.
thanks for the input,
noel
PS: what about red elm, it seems pretty easy to get on ebay for less than osage

i think i found a source for wood ;D

It won't perform well at all but it can make the weight rudderbows did something similar

so would it be better as just ipe and hickory backing, or what else could i use as a belly?
thanks

Ipe, red oak, the oak we have here in scandinavia, masaranduba, osage, +++.. -There are several compression strong woods out there.
-btw, trees like the big one on the truck should not be cut down..
