Glueing up a HBO, and my form I made is 3.5" of reflex. Thinking that may be too much. I bent it in as a test run. Nothing splintered. But I figured out of the form, it will be >2"?
Too mucH?
Don't know if this will help you much, but my trade bow is a BBO straight profile with 3.5" of glued in reflex. I used 2x4 blocks to raise the tips up to 3.5" and only retained about 1.5" after tillering.
nope not enough haha ull lose half of it when it comes off the form probly some more after also brock
Hey Vanillabear,
Not doubting your results at all but I have had the opposite experience.
I now use several thin lams for that reason. I was thinking the more glue lines helped it keep the reflex. I was also thinking that is why glass bows maintain their shape better off the form, I know the glass has a lot to do with that also.
I glue in around 4-6" (depending on the final length of the bow) of reflex and 1/4" deflex. I normally end up with about 1/2" deflex and around 3" reflex.
Just the way I do it.

I see where you're coming from and that is my understanding of how and why the "Perry reflex" works so well.
I also think that you are right in your analogy of the track, it's a way of pre-stressing and storing that stress in the limbs.
Probably more than in the multi-lam limb.
Good points

Well, it felt like too much, I ended up gluing in 2.5" of reflex. Guess I was chicken it was going to pull a splinter on the belly.
Well see how much it holds tomorrow.
3" to 4" s max to me. 2" to 3" is usually what I use. More than 4" has given me more set because of overstressing I believe.
Hickory has some stretch to it so 3.5" with a hickory backing is not like 3.5" with boo backing.
I agree my 4-6 is allot and can be a real pain to tiller. I only do that on the form that I use multiple lams other wise, like the trade bow this year it was 3" of reflex.
A sinewed Yew bow I'm working on pulled over 6" of reflex into it and it is giving me fits!
