Can it be done? Yes, I definitely think so. Hickory can take it.
One I made and posted on here apparently chrysalled. I made it probably a little short for the weight, it was like 125# @ 32", 74" nock to nock or so, maybe a bit shorter. So my only suggestion would be to not make it too short,
. Maybe go a normal 78" nock to nock for anything over 100#. Although then you gotta deal with the weight issue, as it's pretty dense, if your gonna make a real heavy bow over 100#, imo. (This is why I made it shorter) But all that said, I am really a fan of hickory. In my opinion, it is the best bang for your buck when considering your options in most lumber yards. And it is definitely the best board bow choice for your buck (although I would like to try an ipe board bow, I read/hear ipe can be good in tension if the grain is good?). I mean, I don't know why everyone opts for red oak board bows from lowes / home depot, when they could just go root through the hickory boards at menards for the same price, and have a chance at a much better quality wood? (maybe no access to menards?)
