Title: First Birch Bow.
Post by: loefflerchuck on January 04, 2018, 01:38:11 pm
I would like to try almost every wood and design in my lifetime. I have never made a birch bow until now. We have water birch that grows wild around here and some other species planted in peoples yards. This stave I picked up in a hardwoods store. I got a shaft maker a while back and that lead me to start buying lumber from a supplier. They are really good about letting you sift through the stock. Basically a board good for shafts is also good for bows. I found a piece of birch(dont know what kind). with hourglass grain on the face. Brought it home and used half of it for arrow shafts and cut off a 2" stave from the best part. 15 minutes with a draw knife and I had a single ring back. I went for a very simple design to just see how birch is. I have always heard birch was a okay bow wood. Nothing special. Because of that I am quite happy with how the bow turned out. Overall a pleasant shooting bow.
 
 62 inch long. It has a 41 pound draw at 27". The handle and tips have overlays of red bloodwood and yellow canary wood over. The bow is finished with 5 applications of tung oil. The string is 10 strand B-50 endless.
 I tested this bow with the arrow in the photos. The arrow is poplar wood with 1/2" high wild turkey feathers 5" long. The arrow weighs 441 grains(more than 10GPP) and has a 46 pound spine. I shot 10 times through a chronograph. Took away the fastest and slowest speed and averaged the other 8 shots. That was 164.3 FPS.

I spent most of the first 17 years of my life on Birch Street in Denver. That is enough reason to make this bow.

Good looking bow and sounds like good speed numbers to me! And good looking design. With that example, I’d say that birch is a good bow wood. Did you heat treat or induce any reflex into the board after getting a ring chased?

Kyle, I did nothing special to this bow. The stave was very flat, so did not induce reflex. I kind of wanted a pure birch bow. No heat treating, no stain, just simple.

nice looking for sure, and some respectable speed. I like the design you chose Chuck.

Mo, Yellow birch often milled/supplied for the commercial hardwood market. I have not tried too much in way of heat treating or bending with our local white birch variety, as have heard about mixed results with some of the other lighter subspecies .

Good looking shooter from the board supplier Chuck with nice profile lines all around and an ambidextrious shooting handle to boot.Looks like the board may have come from a big tree with the nice flat back it's got.How are the arrow shafts from the board?

Very nice bow.  The wood looks like Yellow Birch

I dig it man.  :OK

Yellow birch is listed as having a higher SG than other birch species so maybe that's what you've got there. Yellow birch bark is very nice looking and makes a great backing.

That's a sweet bow.  I would be grabbing more boards from that supplier.

Thanks guys. I was thinking yellow birch as the wood looks a bit yellow, but had no idea.
Rsp, I have not gotten too many staves from lumber until I started looking for shaft wood. Now I think it is a great source. With a bit of searching I can find a $30-$40 board that I can turn into 4 staves with a single growth ring back. When they are down to stave form it is the same as a good split tree stave but a lot less expensive. I've gotten white oak, birch, ash, and hickory this way so far.
Ed, The shafts turned out nice from the wood too. I may make arrows to match this bow. Kind of cool having a bow and arrows all from the same piece of wood. The arrows I made for this Ishi bow were from this board. Ishi used birch during his time at the museum for some of his arrows.

Interesting shape and tiller Chuck.  I like the simplicity and different approach.

Thats a good quality about some woods that to me that osage can't fill.

I think it depends on the species of birch. supposedly the Mongol's made their hornbows out of birch according to this article http://www.coldsiberia.org/monbow.htm. Based on the wood database values Downy Birch should be the best, with Silver and Yellow after that. But who knows whether that's an accurate predictor? The Mongols most likely used either Downy Birch or Silver Birch since those are the types most likely found in their region, so I would say those would be good bets.

Lovely bow! And really nice finish work. I really enjoy these simple bows. I agree that it would be great to have a bow and arrows from the same tree!

No never tried heat-treating Yellow Birch.  I found that even though it is more elastic than Paper Birch it still chrysalled when stressed a bit too much.  It was great sinew backed though

With a bend like that any wood will work! Birch grows like a weed around here, a few species of it. I gotta try it one day

plain simple beauty!
Elegant lines and nothing superfluous on that stick.

I have never tried birch, the species here in my homeland are not that easy to chase a ring ... so I will go with a sapling and simply throw of the bark.

I really like this bow, such elegant symmetrical curves, beautiful tiller and great speed. I have yellow birch in my bush, I certainly wouldn't mind trying to cut some logs and make a bow or two as well from it. You inspired me!
