where's the poundage
« on: May 30, 2018, 11:59:25 am »

So I am currently building a horsebow out of Rattan Manau. I don't know how popular that idea is around here, but over at fletchers corner it got quiet famous because its such a nice "light version" of an actual hornbow.
I'm planning to face it with american walnut, but tiller it as good as possible beforehand. I scraped the Manau down to about 13-15mm and strung that whole thing to braceheight. I gave it a careful littl pull and had to notice it was extremely easy to pull. Even though I am going to face it I'd still like it to be a little strong in of its own.
So I took the heat gun and roasted the belly. (at this time around 2-3 times on both limbs) After every heat treatment I noticed the limbs got quiet a lot harder to bend and it was noticable harder to string as well.
But as soon as it was at braceheight... boom poundage gone! Feels like 5 pounds. Now I have never pulled a recurved bow or one with siyahs before. Anybody got an idea? ???

Because this is not a horn bow I'm going to move this to "Bows" for better visibility.

Wait, so you got the string on and it lost pundage?

When you say "face" it with Walnut do you mean "back" it with walnut? If so a backing will increase the draw weight quite a bit, more than you expect. I've never used Walnut for a backing so I have no idea how well it will work.

no I mean walnut on the belly. Manau is not something that can make use of a backing, since its only problem is compression and a lot of set

A belly lam will probably still increase the draw weight but I'm venturing into guesswork now ;D ;D

@Ryan jacobs
I mean at least it feels like it. or more specifically: the pundage when strung didn't increase while it got harder and harder to string and bend by hand :o

Well, it really doesn’t matter if you’re adding a belly lam, that’ll add a couple pounds.
