Now the magic part.

I use a sharp scissors and cut fringe around the edges.

Before the magic

Then I stitched a dowel in top of flap and attached the Flemish twisted strap. Again with two colors.

I cut lace from around the outside of my leather. I use two different colors. A cream colored hide and a tan colored hide.

I stitch the area around the the knife and to each side. First in the cream color. Then I come back and stitch between the cream color stitches with the tan lace.

I’m not very good with leather work.

I’m often afraid to cut up my leather and waste it on something that I don’t have the ability to create.

I found it easier to play around with my scrap pieces.

I find two scrap pieces and staple them together. The staples hold everything in place while I lace it together. One piece is longer than the other. The longer one is the backside and flap. The shorter one is the front side and where the blade will be carried.

Guys I agree it’s a candidate for bow of the month but it was a bow blank from JiM Hammer and I won’t be doing the wrap on the handle. I will probably enter the black locust though. May not be as sexy but a faster bow at 10 grains per pound. And I am no photographer!

Bows / Re: The best shape for a reflexed bow?

The design I’ve been using for years is closest to the third design. The speeds are close to what I get most of the time. I have had upward to 186 ft per second. Not often though. Interesting topic thanks for sharing. Notice the farther the tips get in front of the back of the bow the more speed. That’s with the deflex in the handle to help the stress on the inner limb.

Thats a really nice looking bow. Perfect amount of wiggle to it.


Gotta agree. Nice wiggle. Should be a nice bow. Pleasant to the eyes too.

Simk: How do you optimize the front profile, and especially the tapers? The front profile is more of a practical problem, because in the model you can make it as narrow as you want, but in real life stability becomes a real concern. That’s the main reason I wanted to use the same front profile for every bow model.
As for the taper rate, I optimized it with strain distribution in mind. What would be a better approach? The 0.008 taper I used seemed to work well for every model.

Ryan: Yes, energy storage is mainly determined by the unbraced profile. That’s exactly what I wanted to examine, and of course the results of that difference also. All the “bows” had the same net reflex, yet they still behaved very differently.
