Anyone ever build a 100 pound pyramid bow just for the heck of it?

I've made about a dozen bows now, anywhere from 30# on up to 70#, and I want to do something stupid... I don't even know if I could pull the thing, but I've got to try it. Not that I want to shoot down airplanes, or hunt extinct reptiles, just to see if I could pull it off...

I've got access to red oak, hickory, and some really tight-grained jatoba.

So, based on a 65# bow that I made for a customer recently out of hickory and jatoba that was 2" at the fades, 1/2" at the nocks, 1/2" thick, and 66" NTN, this is what I was thinking of as a starting point:

1/8" hickory back over jatoba
62" NTN
2 1/2" at the fades (maybe 3")
5/8" at the nocks
1/2" thick belly at the fades, tapered to 7/16 at the nocks

Whaddya think? Am I being crazy enough??

do a site search on Druids bows. he has made a few pyramids above 100lb I beleive. they were staves and not laminated however.

Ditto on druids bows.....do you have anything better than jatoba for the belly? And of course it can be done...just needs the right execution of materials,design,and expertise tiller....that's all

Well, I do have access to Ipe, but I'm not a fan of it... What belly wood would you suggest?

I've made a 70"L,  2.3"W elm Holmegaard at 105# that sent a 3 ounce ash warbow arrow just as far as a English style warbow. Still have it.  I also have a 72"L 3"w red-oak pyramid that is 110# that I used to practice with to build up my strength before I successfully made a war-bow.

Really? Wow, I never would have guessed that such a long red oak bow could draw that much...  How wide are the tips?

Tips are just under 1"W. Like I said it was a bow more for a workout that performance.
