I made two light ash warbows about two years ago. Some guys from a reenactment company didn't have the cash to pay for yew bows so I proposed them to make ash bows. Ash is much less expensive here in Switzerland and i have a lot of clean straight staves. It's also faster to process, hence the lower price.
The funny thing is, I worked more or less exactly like Jaro described, making the bows a tiny bit wider and with a less pronounced rounding on the belly. The light toasting of the belly was also the same
Both were about 36mm wide at the handle, about 190cm ntn or a bit longer and had around 80 to 90 pound at 32 inches of draw.
Doing a few shots, i could not notice any big difference in performance compared to yew bows, but the testing series was small and I'm no expert warbow archer, I can't draw more than 85 pounds (what a wimp
).
With my 'normal' whitewood bows, they are mostly around 55-60 pounds, I prefer it the other way round: a perfect flat belly and a more rounded (or trapped) back. And as narrow as possible. I feel that this gives the best performance with the white woods. I always wonder if the medieval boywer would also have chosen to go that way, to avoid all the problems with chrisaling and string follow...?
