The first glue up is belly and core, (with the belly lam in deflex)?
The second glue up you reversed the bend before adding the backing?
All three lams red oak?
Yes, yes and yes. The first glue up is belly and core lams, with ~6" of deflex (going from memory, would have to check for the exact amount). Second is back lam onto the first assembly with ~2.5" of reflex. All 3 lams are red oak, from two different boards. I used red oak for this because it is a workable bow wood and cheap, just to see if it worked at all. It is also fairly tension strong and compression weak, so I figured it would really show any effects from the strain reduction on the belly.
Got it worked out to just under 28" last night:
It looks pretty good in the funky lighting in my shop. Now that I know it will survive being drawn to 28" I can work on the grip and get it to where I can take some shots. It showed some set after being unstrung, but I didn't try to measure it yet. Will get the grip and nocks finished to shape and then see how it does after some shooting. It is showing 51lb @ 28" right now, so I will also go over the limbs and round all the edges some more to take a bit off of it.
Once I have it shooting I will update my lam bow experiment thread with the details and results of this bow.
