Design advice and low draw weights
« on: June 06, 2010, 02:59:00 PM »
I want to make a bow for my girlfriend, but she's never used a bow in her life (or her arm muscles, for that matter) so she needs a very low draw weight. I tend to have issues hitting lower target weights, is that common?

As for the design, I was going to use some more of the hickory I have here to make a slender ELB with recurved tips (I just love bending wood  :p ). Could hickory take the D shaped belly AND recurved tips without breaking? It'll also be about 61" total length, like my last one.

Hickory is best suited for a flat bow.  Being weak in compression, it doesn't handle D cross-section of the traditional ELB.  The few ELBs I've made of hickory either fretted or took more set than is acceptable.

Thanks, 4est.

I has heard hickory was bad in compression, so I wasn't sure it would work...

I agree with 4est.
  You could make it with a flatter belly but still relatively narrow and even trap it positive to the belly(wider belly than back). At a low draw weight you shouldn't have a problem. If you add recurves you will be increasing the draw weight and adding more stress to the limbs.
Make the most of all that comes and the least of all that goes!

im with these guys, from what i know a true english longbow D shape is harder to tiller than a flatbow. with a flatbow you can get it close then trap the limbs or thin their width to get the weight you want.

I'm not an elb fan. When I make bows for my daughter or children I make them as tall as the person and they are flatbows.  They are usually an inch to a.25 in and bend in the handle. Jawge
