It makes good bows. The drying can be a problem. It will tear itself apart if you leave it round. If you cut it to the pith it doesn't check too much. That means that you need a piece at least 2" dia at the handle to prevent handle pop off. It shrinks a lot so even if you split it right down the middle, when it dries it will less than a semi circle. See pic. Freshly cut on the left, dry on the right.( excuse the drawing
it's early) Like PD said it's heavy, don't throw it in the water, it sinks. Even bone dry and salt water, it sinks. SG is about 1.2.
You can make a bow with smaller dia if you rough it out to bow shape when green but be prepared for the handle to spit as it dries. It will. Just fill the split with primitive bondo. Scrape the bark off when fresh. I use a dullish draw knife. Shellac the ends and back and give it a year. Try to keep it in a humid spot for the first couple of months. I think mid winter is the best time cut because it can slow cure for a few months. Cut more than you need because some will self destruct. It's a nice wood to work. It doesn't seem to help bark removal to cut it in the spring. I've cut lots and I've had one piece where the bark actually peeled off, the rest had to be scraped
