Title: Glass Bendy Handle - Finished - Chrono results
Post by: CardboardDuck on March 17, 2013, 08:36:00 AM
This one was interesting. It has a total of seven laminations, five hard maple and two fiberglass, for a total of .570" with a .009" taper. First I reduced the width to 1.25" at the handle and 3/4" at the tips, it was just under #100 @ 28"... so I reduced it further to 1.125" at the handle and 7/16" at the tips, now it is #70 @ 28"... It is 61" tip to tip and 60" nock to nock. Everything was getting way to skinny for my liking so that's where it sits now. Very lightweight, and very fast. Some pics -

That's neat and your tiller looks like a perfect arc.

What's it like to shoot?  I just can't help but think that without a handle/grip it would be uncomfortable given it's weight.  Much handshock??

It does have a tiny bit of handshock, but not as much as you'd think. I'm still not sure if I am going to put a wrap on it, probably not. I was surprised at how fast it is, I need to find a chrono, it is way faster than my 62" hybrid and any of my other bows.

Cool thing- was it intended to be some modern kind of elb/warbow?

That is simplicity!!  Great tiller , but it might be a bit heavy for me .....

MoeM- It was just something that I have wanted to try, not really supposed to be anything, but it reminded me of an eastern woodlands style bow.

Thanks Old Man Roy   :p  


Heck Kenny, it's too heavy for me... I weighed it again after I had sanded it and put some wax on it - 69lbs at 28" - but I only draw a bendy to about 26"   :archer2:

Outstanding!   That taper rate is the ticket.

Thanks brad, you pointed me in the right direction with the boo/osage elb you did. If I were to do this again in think I might even go with a .010" taper.

Wow, that tiller is right on!  If I ever do one of these, I'll follow your formula for taper and go a bit thinner in stack so as to me able to draw it!  :)    Thanks for describing and for the pics.

Any chrono data?

Well I picked up a little chronograph and shot it about a dozen times. One was 204.5!!! and the lows were in the mid 180's.

Most were right around here -

Not a super speed demon, but pretty quick   :)

Freakin fast- for a stick^^
Use a 8/9 die like an elb ang give her some reflex next time- and 200+ won`t be a thing...
(U used 9gpp?)

GPP? I'm new to this stuff ...  :)

My arrows for this one are Gold Tip Traditional 5575's with 145 grain field points. I don't know what that calculates out to... I think thats around 400 grains.
Title: Re: Glass Bendy Handle - Finished - Chrono results
Post by: MoeM on April 02, 2013, 05:59:00 PM
GPP is grain per pound- total arrowweight is usually taken with 9gn per # drawweight at 28" (which is the drawlenght for the measurement too)
So for your 70#@28" arrows shall weight 9gn*70#=630gn.
This has nothing to do with ideal arrows at all- just a normed testsituation.
Ed.:
I had the idear for a bow like this for some time but I worry mostly about the handle so I thought of some kind of short and thick plam to enable some round outs on the edges but that wont be 2bending through the handle...
so it would remain a LB with a short riser^^
Mine was considered to be a LONGbow so about 70" to allow smooth draw- I can`t imagine that your`s has a smooth one- not for a bow and not even for a 70#?!

Interesting and a nice bow. Bue--.   :)

This is where my inexperience comes in...

I have never understood what people mean by a "smooth draw". When I shoot this bow I don't feel any "sudden" changes in weight or how it draws. What is a good indicator of a smooth draw?
I have been thinking about wrapping the handle with leather, but I just love the stick look I guess  :)

I'll try to get a video of it shooing up tonight.
