Most war bow weight longbows I've seen are small enough to fit completely in your hand. That would mean that making a lower poundage bow (Like 50 pounds) Would have to be slender. Would using a lower RPI stave be able to yield me a full size, yet lower poundage bow? After all, I might be able to get the stave for cheaper, if not free.

Deflexing the stave might help? But it gives bad cast with low poundage...

Make the limbs wider and use some soft species of wood.
I think willow/goat willow would make a big bow, maybe poplar/aspen too.

Just speculations.

a 50# yew longbow will still be 1 inch square (ish) in the handle.
Don't over think it just make one :)
Rough out dimensions for a yew longbow 50#@28 would be 1 !/8 wide for the center 12 inches. Then taper to 3/42 wide 12 inches form the nocks then into 1/2 at the nocks.

Are you talking about an English war bow or an English Victorian long bow?

Sam, do you know for sure how much you can pull? How tall are you?
if you want to make a bow that works, sorta like a warbow, you might be able to find some something at the lumberyard easy.

Im just under 5'7"

Im pretty sure i could use maple or something and heat treat the belly. My questions was just hypothetical.

I don't think it can be done!
If you take a specific Mary Rose bow as the size and shape you want and make it from different woods, rather than simply being lighter, the belly will probably chrysal, take a load of set and possibly break whilst still being quite a high draw weight.
One problem is you don't define your terms... what do you mean by lower poundage? 50# 40# ?
I must admit I'd like to see Pat B's suggestion of a MR bow made of balsa to see what it did  :)

   I used to make a lot of ELBs from cherry backed with white or red oak. Attractive and dimensions are pretty decent at 1 1/4 wide for 50# bow around 70" long.

ERC will make a physically larger bow for a given draw weight

+ 1 for ERC as Marc mentioned. Plenty of massive looking bows, that would be in the 120-150lbs range if made from yew, but draw about 70-80lbs from ERC.
