Osage ELB

<< < (2/4) > >>

Del the cat:
The front profile is not a straight taper from grip to tip, although some bowyers make 'em like that. It's basically two tapers one for the first 2/3 of the limb and then tapering further to the tip. All blended in to a graceful curve (I often describe it as being like the wing of a Spitfire). Tend to rough taper them straight to about 20mm at the tip, until the limbs are coming back nicely, then taper the outer 1/3 to fit the nocks. Leaving it wide early on gives wriggle room in case it tries to bend side ways on you, as you can narrow the tip from one side or the other to help correct.
Ignore the "D" section stuff, until it's coming back nicely, then you can round off the corners of the belly... (for same reason as leaving the nocks wide).
Some people make the mistake of shaping it like a longbow before even flexing it.... I tell 'em you tiller it until it becomes a bow... you don't make a bow then tiller it.
Have fun JW

Hamish:
I have seen ELB's made that taper in a straight line(or a gentle curve) from the handle to the tips.
I have also seen them stay constant width for the middle third, then taper to the tips.

The first method is trickier, as they tend to twist to the side, more so than the second method. I have had really narrow elb's made from hard wood want to bend side ways, at the first stringing. They need to be trained and pulled back to straight. If that doesn't work, you might have to tiller the side of the belly as well as the keel.

I personally use the method that the late Chris Boyton used. 12" long middle section, at the widest. Then measure back in around  6" to 8"  from either limb tip, make a line perpendicular to the centreline of the bow, to a width of 3/4"
 I draw a straight line from the ends of the middle section until they meet the 3/4" section. From the 3/4" section I then draw a lines to 3/8" tips.(you can leave them a little wider1/2 to 5/8" to have room to align the string if necessary.

This method maximizes the lateral stability.

There is no one single right way to make an ELB, as you will find many historical variations in the design. I agree with Del that the graceful, subtly curved taper does looks the best.

My process involves making the rounding of the belly when floor tillered, or at least by the time you get to brace height. My reasoning for this is it allows me to get in early and tiller the sides of the belly(rather than just the keel) and adjust any lateral bend as early as possible, if its necessary. You can lose a lot of weight very quickly if you use the faceted method before deciding to round the belly off in the later stages of tillering.
Anyway if you use the other method, like Del{A real master) and it works for you then no need to change. It's the end results that count. Horses for courses and all that.

I also like to put on the horn tips before the bow is  fully tillered, so I can tweek string alignment at brace height if necessary.

This post will answer your questions pretty well - and as you can see from the consensus there are no rules per se.

Have fun!

Plus 1 here for the build along!  I’d watch it. 

Muskyman:
After looking at some ELB designs the stave I thought was perfect for one turn out to be exactly backwards for a ELB. I actually thought for some reason that the back was rounded and the belly was flat.  (A) I’ll have to look for a different stave for a ELB. My recent and better staves won’t be ready until next fall anyway. I’ll still be watching with much interest. I’m not sure I’m ready to build one yet anyway. To much to learn yet.

Either way, good luck with your build.

I would be happy to do a build along, but you all better be some of the most patient persons on the planet! I hop, skip, and jump between projects, abandoning something as soon as I hit a tricky bit that needs to be thought over. Also, I am finding it difficult to reduce the size of photos with my phone and laptop (both are fairly new), and this platform is notorious for wanting 2002 flip phone size files for posting. But yeah, I will consider it.
