boo backed bamboo bow

Ive taken a brief break from my arrows to build another bow ive had rattleing in my brain for a while. Ive done similar ones like this but this deflex reflex design in a boo on boo is a first for me.  Most of the time spent was figuring out my thickness tapers and selecting the right 2 sections of boo slats.  I plan to side tiller only this bow to retain all of its belly and back intact.   I have a three part video series on youtube that I started and will continue to post updates.  the first link here is the 3rd video showing where im at now with it.  More work to do on it yet.  Im hoping to have something close to 70lbs. if i miss this mark ill shoort for 50lbs.  If i feel like its performing well ill bring it to flats.

I saw your utoob video of this coming bow. Very promising.

thanks hamish!  glue lines look good so far so good.   I did a deeper cook on the belly lam prior to glue up.  I figured on the belly that would be best we shall see.  the back i only did a mild cook.  The cook on the belly maintained color change deeper then the back.  The nodes are spaced accordingly belly and back.

Good luck! I built something similar and it got so narrow I was loosing side stability and it wanted to flip on me. I had to reduce the reflex by cutting the tips, which caused the weight to go back up. Im expecting to see you fight a similar fight.

Thanks I’ll need it.  I hear ya. These are a challenge.  I have been able to get lucky with these so far.  I’ve had my share failures too prior to that however.  The neutral plane is also important factor with these type build.  Also careful measures.  I carefully measured my tapers and got pretty close.  Fingers crossed and time will tell if I got them right.
