Honey locust is ok wood. Not great wood, but ok. Useable.
A stave of mostly sapwood, from a sturdy sapling, with good density (for the wood), wide rings and a crowned back can be treated like other white woods. Don't bother chasing a ring of heartwood.
HL takes set pretty easily, more than ash or most elms. Make sure it's nice and dry. Make a 2" wide limb at least, and at least as tall as your nose. If you can't do that, use everything that you have as far as width and length. Make a flatbow with about half the limb length parallel, flip the tips, and heat treat the belly.
It'll shoot if you do that, and it's not gonna be your last bow, anyway! ;-)
