I'm shelving the plans to experiment with my other idea (
http://www.primitivearcher.com/smf/index.php/topic,73157.0.html) to induce deflex, and have instead started to play around with just gluing it in with multiple layers.
In the past when I've glued in reflex, I found that the out-of-the-form reflex was about half, give or take, of the reflex in the form. So, thinking that's what would happen here, I deliberately made a form with twice the intended deflex for glue up, thinking it would spring back a fair bit out of the form.
Nope.
It kept nearly all of it! I guess that's what happens when you use lams of even thickness, instead of a thin boo backing with a relatively thicker stave.
I was originally going to make just a D/R bow, but given just how much deflex there is (about 4"), I'm thinking of adding some recurves too, which would mean needing less reflex.
The timber here is ironbark on either side of a maple accent strip.
