Bamboo backed selfbow

[sleek]

Don’t you look at the pictures? It’s laying on the caul 4 post up. That’s not set though that was calculated precisely so this bow would have deflex and reflex . So it would shoot arrows far.  I have ocean front property in  Montana also . Arvin

The way they talk about global warming,  who knows, ocean front property in Montana may not be a bad prospect. 

Any idea how many inches set it took  my calibrated eye aint what it used to be.

That’s a great looking BBO. Thanks for posting the pics and showing us how you do it. Very helpful!

Sleek it was 3-1:2 off the wall at handle off the caul. Now probably have that. Well see if it’s enough to shoot 235 or so. The good thing I think is it weighed in at 18 oz. Arvin

Nice bow
I'd have gone with a little more bend out of the fades.

What ratio of Bamboo to Osage did you wind up with

[PaSteve]

Very cool Arvin. Wish you the best of luck at the Flats!

What ratio of Bamboo to Osage did you wind up with

Marc I’m going to say45-55 to 40-60 . The lower numbers being  bamboo. I think with this design  and these materials this would have made a better bow with less set at 40-45#. That would have gotten the materials more even . That is one thing about flight shooting and building bows for flight.  Trying to hit those weights with unpredictable materials. I have heard it on here that the bow will be what it has if tillered right. So if a bow starts taking set early on the wood does not have that draw weight in it. Compromise and make less draw weight bow.  Hope your able to understand my thoughts . Please respond if you are or aren’t in agreement. Arvin

[Marc St Louis]

Well that's not too bad.  Usually the ratio is more like 20/80.  Who knows, maybe with those ratios there will be better performance, I tend to think not but you never know.

[Selfbowman]

Marc I only built a hand full of bamboo backed  bows . So much to learn!!

[Bob Barnes]

that's the only way you'll ever know what works best for you and the intended purpose.  I agree with Marc about 20-25% bamboo maximum for a BBO... "Less is more"

Ok guys I could not wait. Shot two 454 gr bamboo broadhead arrows one 245yds and one 240 yds. That was with D97 . Pretty sure I’ll get 240 yds with linen at the flats with it. We’ll see. Better than I thought. I think the 18 oz had a good bit to do with it. Arvin
