Minimum width flatbow
« on: July 29, 2010, 01:39:00 am »
Hey everybody. I'm pretty new at bow making and was hoping to get some insight.  If you wanted to make a D style flatbow around say 45#@26 around 68" how narrow could your limbs be?

Welcome to PA!!!  :) It really all depends on the kind of wood you are using.  I have a hickory backed ipe laminate bow I built last year that is 7/8ths of an inch wide at it's widest point, and i also have a red oak board bow I built that is around 2 inches wide at its widest point.  Maybe someone who makes more d bows will chime in with a better answer.  :)  Good luck to ya, can't wait to see one of your bows!  :)

What I have right now are some white ash staves about 72" long that I cut from a friends property about 2 years ago. They have been seasoning in my shed and I believe that they are plenty dry to turn into bows. At least I'm hopeful they will become bows. I've been doing alot of studying about bow design and from what I gather so far it's good to start with a D shaped bow.

I'd say you have a good amout of leeway Ash will make a longbow (at a pinch) which is pretty narrow, but I'd say go for your flatbow 3 fingers wide at the widest, narrowing down to as thin as you dare like ;D.

I would say for the weight and at that length I would go at least 1 1/2 to 1 5/8 at the fads.
I usually take that to mid limb and the tapper to the tips. That should get the weight you want.
I have never really made many d bows,I usually make my belly flat. That could change things.

I'm not sure, but I think he means D-shaped as in bend in the handle, not a D cross-section. I'm no expert but I think Ash could handle 45lbs at 1 3/8" wide out to
mid-limb.
If you never have time to do it right, you'll always have time to do it over.

It might but you're better off to go 1 1/2: wide.  Ash can have a nasty tendency to chrysal

By D bow I do mean bend in the handle. I was reading one of the sample articles n this site and it was about making sapling bows that bend in the handle. It looked like they were made fairly narrow. I'm not using a sapling but I was figuring even with a regular stave you could get away with this same design ???

Yes you did say flatbow, northvarcher. I'd go 1.25 in to 1.5 in. wide. My site may help. Jawge

My mistake. I was thinking any longbow made with a flat belly would be considered a flatbow.  If you make a bend in the handle with a rectangular cross section what kind of dimensions would you need? How much width compared to depth at the handle section? You still want to make the belly flat right?
