Bows / Re: The best shape for a reflexed bow?
« Last post by Tuomo on Today at 04:05:13 pm »
Nice idea, Willie, and definitely worth trying. But I see many problems as well. How can I be sure that strain distribution is the main feature of an exceptional bow? Why not mass or curvature distribution, or the side profile combined with some other parameter?

I don’t have an exceptional bow—just some good ones. Their common features are that they have minimal set and they are deflex-reflexed. Set is a material-related parameter, and when making wooden bows, minimizing set is only possible when strain is distributed as evenly as possible. I’m going to make some bamboo-horn bows in the near future, so with horn the set parameter is almost eliminated. Simk has made a lot of very fast horn-belly bows and has taken very good and reliable measurements of their performance (see Traditionell Bogenschiessen 117), so there is potential. But again, this is how we implement theory in a real-life bow.

So, I’m going to make deflex-reflex (or even deflex-reflex-recurve) bows with evenly distributed strain and test them. A long to-do list…

Around the Campfire / Shipping option
« Last post by JW_Halverson on Today at 04:01:30 pm »
Caleb Flies recommended to me using a company called Pirate Ship to send bows to folks. I used to be shipping a bow for twenty bucks, but have been paying as high as seventy-five lately!  I was skeptical, but went to the website, registered, and created my first shipping label. You gotta be able to weigh the package accurately, AND enter the dimensions, but it's really not that hard to do.

Pirate Ship has you pay them the shipping (and in this case, insurance charges), then you print out a USPS shipping label that has all the pertinent info on it including their QR codes and bar codes. Easy peasy. What did it cost me? $23 and change, that's it.

How come this works, doesn't the Post Office have set rates for postage? Yes, they do. One set for people walking into the post office and another for businesses that negotiate lower rates for large bulk shipping. Catalog companies, online sellers, and the big sellers all get insane discounts that WE THE PEOPLE are excluded from getting. Companies like Pirate Ship open the back door to us so that we can piggy-back on their contracts. I am sure there are other start-ups doing the same, maybe some better, but I'm already impressed with this outfit.

A bunch of other folks have been telling me they have had excellent luck with Pirate Ship, so I went into this with a little confidence. Maybe you all have known about this forever, but maybe this will help others. As the great Canadian philosopher Red Green said, "We're all in this together."  And keep yer stick on the ice.

Where my limbs are centered up with the string I make the limbs flat as possible.

I know most guys keep there snake bows flat as possible across the limb section . I like to thin the outer parts of the curve. Here is an example of a limb section thickness.

As for the taper rate, I optimized it with strain distribution in mind. What would be a better approach?

Model exceptional performing bows in virtualbow to find what the best strain distribution looks like.
Use this distribution model to test different degrees of deflex/reflex, different tapers and lengths etc.

And after. All done

The nice thing about the fringe is it doesn’t matter if you have odd shapes that don’t fit together ideally.

It just adds character

Nothing fancy, but I like the look

Now the magic part.

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