non-traditional trad bow.

ive had some with little twist but easy enough to heat and reset them again.

sounds like a good method.    so you adjust the siyah on the limb?  I wouuld imagine adjusting the limb might work also, but I would be inclined to get the limb pulling with as little twist as possible before working the siyah

maybe it's easier to adjust limb twist with bamboo that it is with other woods?

sounds like a good method.    so you adjust the siyah on the limb?  ( yes. I set it with the glue to be as straight and aligned as possible by eye then only minor tweaks if any are needed later.). I wouuld imagine adjusting the limb might work also, but I would be inclined to get the limb pulling with as little twist as possible before working the siyah

maybe it's easier to adjust limb twist with bamboo that it is with other woods? (Yes I find that the bamboo is easier to keep from twisting as it’s super stable and rigid in its current form.  As long as you get thickness taper sorted out and equal on both edges for thickness consistency your golden.

heres a few more photos of the new one all wrapped up and now waiting to fully dry up before shooting again.  as discussed earlier with willie its very important to get those siyahs straight and inline with each other.  thanks for looking.

did some speed testing on this bow today and had some slower speeds due to the level of humidity today.  we had rain earlier today and i fugure this played a role on speeds.  I may retest on a different day.  I’ll post a few videos here of me shooting.  I had my daughter filming and the video got cut short and didnt show the speeds! arg.  I redid the video to capture some speeds.  all of my bows were 10-15fps slower today compared to the other day.   182,183fps isn’t too bad at 10gpp.  I’m happy with this.  I suspect the speeds will be better on less humid day.  This being said and despite the slower speeds then hoped I really enjoyed shooting this bow today.  It’s insanely accurate shooter.  It is very close to being a center shot bow with the arrow pass cut out.  Arrows come out with no deflection and it’s dead in the hands.  It quieter too then the other one when comparing the noise.  I’d hunt with this bow!   Thanks for watching. 


Heres a few videos

Thanks Pappy!   Ya it takes a little time but makes for a secure and clean look.  It took me about an hour to do all the wraps. Not too bad.  I’ve done a number of them now and can do it fairly quickly now.

I'm impressed with the wraps, too.  Really nice work.

Beautiful work, Dave. I like the horn overlays on the tips and the wraps. Your work is really impressive!  Thanks for posting your work here.

Well gang im at it again!  let the experiments continue.  posted here are some new pics of a related test build of a 3 piece boo bow with seemless integrated siyahs on the limbs instead of separate levers glued and served onto the limbs.  The hangup with attempting this in the past has been cracks and splits on the bends.  Ive tried every known process to get this done with exception of something crazy like ammonia which i had no intentions of trying.  Ive tried steam, boiling, oil and dry heat along with varied timed pre soaks for days at a time and used a metal band also all resulted failures until now!  I had a good conversation with Kevin, (sleek) here actually and he and I were talking about my bamboo bow builds and wondered if id ever tried bending in my tips before.  I proceeded to tell him about all the attempts and failures explaining that very dry bamboo pole i have access to dosent bend well and had only worked with greener pole.  This later got me thinking and stewing about it after our conversation and wondered if i had perhaps given up too quickly.  I hit the shop and began some more test bends and after about a dozen more failures i figured this wasnt going to work and just accept my defeat. then it dawned on me,  when i was boiling or steaming the boo tips and quickly moving to the jig i would see it evaporate very quickly and crack every time.  So i figured why not wrap it in cyran wrap prior to moving to my jig then bending.  well that was the ticket.  worked like a charm.  gonna have to let them dry for a while but they held up nicely.  These pieces shown here are just test pieces and may use them for a lighter weight kids bow.  the nice thing about these recurves will be the reduction in mass on the tips hopefully resulting in faster bows.  we shall see!  anyway thanks sleek for bringing this back to my mind and wanting to try it again.  heres a few pics.

Dave,

Are you adding underlays or other pieces to keep the tips stiff or letting them open up?

Gonna try both.  Gonna do some working recurves and then also try curved underlay of boo lam with rind side facing out towards archer.  The should bend nice that way too.
