I happen to have the exact opposite opinion on hickory anymore. I absolutely love hickory as a belly wood. Although I do agree with you it is not the best choice for 130 + bows, I've done it. I would make it longer than ipe or osage to take the compression better, but I have had great success using hickory as a belly wood, and I think most of the stuff people say about it taking excess set it not true. It definitely ain't true for me. If I glue in 2" reflex, I will be left with close to 1" reflex. If I glue in 1" reflex, I will typically be left with a straight stave. It definitely has the potential to be faster than ipe and osage as well due to it's lighter mass. I just finished a boo/maple/hickory bow, 75# @ 32", with about 2" glued in reflex, it held about 1" of it, that is just after being unstrung after being shot. And it is very fast and smooth, really light in the hand compared to ipe or osage bows. I really like this combo. I have stated countless times on here, I just don't understand hickories bad rap. If I was getting set and chrysals, etc, than it would make sense to me. And I definitely don't heat treat.

Not me. I've had horrible 'success' with hickory on the belly of anything, except maybe flatbows. It's just so much better on the back... so that's where I leave it.

First off, thanks guys for your replies.  I love this forum.  Whenever I can't find the answers elsewhere I ask on here and I always get educated responses from experienced bowyers, so thank you. 

I completely understand that osage is the preferred wood to use on the belly.  I had thought about the problem with the thickness at the tips if I use that route (osage as the belly wood and hickory as the core wood), and that the osage would be almost down to nothing at the tips.  Then I thought, "what if I use hickory on the belly?  I have a full 1" thick of that, and with osage in the core as 1/4" I could get 1 3/8" thick at the handle....but I know that hickory is notorious for being superior in tension.....not compression."  If I used osage on the belly and only used 1/4" of hickory in the core, my thickness in the handle would only be 1", and that's not enough thickness for 120-130#.

The strange thing with all of this is that I had just made a bamboo-backed hickory that is 66" and 82# at 32".  I was surprised that it didn't take too much set, even when drawing to 32" on a 66" bow!  Originally I had it at 72" and even then it had less than  .5" of set, but I piked it so I could reduce the mass and raise the draw weight a little at 32".  I say you learn from your mistakes, and I experiment and try something different with every bow I make...not because I set that as a goal, but because I just naturally do it.

I also love to make my bows so that they have an aesthetically beautiful appeal.  In my opinion a bow is a "great bow" if it meets 3 requirements:  Good performance (minimal set, arrow flight, penetration, durability, etc...), beauty (in my opinion), and meeting the specific draw weight and draw length goal that I set before even working on the bow.   ;D
