I was thinking of building my next bow in the bend in the handle design. Maybe 64" NTN and around 55@27. Bamboo or hickory backed ipe of an inch or so in width. Do these designs exhibit more hand shock? Any suggestions? Thanks.
-
you'd think they might have more handshock, wouldn't you, with the handle sharing the work...i have built all stiff-handled bows, so i can't help you there, but i know what it's like when one breaks and you want to try something completely different...
that hill bow: do you think it was the cypress wood or the depth of the limb that did it in?
-
I'm pretty sure it was the cypress. It was extremely light in weight. More so than cedar.

Apex, a bend in the handle bow can have horrible handshock but doesn't neccessarily have to have any more than a stiff handled bow. Lately I have been really studying the handshock issues more from a performance angle. The vibration is pretty costly in performance. If you keep that bow proportionate, not too long say about 60" or so and a slightly elyptical tiller it may not have any shock. Steve

I have been quite surprised with the few Cherokee style bendy handled bows I have built that they have very little shock to them. No more than any of my bows. The Cherokee style has heavier limb tips than I usually make but shoot surprisingly smooth. With thinner tips(less mass weight) and a little kick in the tips you should have a sweet shooting little bendy handle bow. Pat

I've only made about 10 bows but my bend in the handle bows don't exhibit much handshock if tillered well.
-
also, people say that with less mass in the tips, handshock is reduced...but my holmegaard has no shock to it at all...it's all punch!

I've grown fond of D bows because of the ease in construction. They don't have any more handshock than a stiff handled bow, and if it does for some reason, just glue a little leatehr onto the grip area before you attach the grip (rubber insoles work too).
Making them shorter (66" or less) or out of lighter wood eliminates this need though. That's why you could make a Native style bow with really wide, heavy tips, but at 56" long, it won't kick at all.
-
I thought the same thing about hand shock with bendy handle bows. I've only made one it was vine maple that was about 58" it has virtually no shock. Actually less than some of my earlier stiff handle bows. I think the key is in the tiller. If tillered poorly it will be a shocker.
-
I think the more natural reflex the bow has, the more handshock. Alot of the indian bows had string follow which I bet eliminated alot of that shock.
-
Anyone have a photo of the tiller I should be striving for?
-
The tiller would depend on the profile of the bow. Basically you want a circular or slightly elliptical tiller.

So far, my bows made from stiff wood (like ipe & hophornbeam) have less hand shock than my bows made from low stiffness wood (like juniper & elm). I've made close to 50 bows now and 90% have bendy handles....and here seems to be a relationship between "vibration" and wood type (among other things). Just my personal observation.
The ipe/bamboo combination is becoming extremely popular....it's a good choice for any type of bow.
There are some very good threads here on the causes of hand shock and TBB covers it pretty well too. I'd read up on these before starting your bow. ;D

This is the Tiller I shoot for in My Style of D Bow..........

Follow that pattern and you will be very, very happy. That tiller is perfect!!! Good luck!
