Well I think I figured out how to upload photos! This is my very first bow build, I'm shouting for 45 lbs, at 28". Still in the tillering process, but I think it's going fairly well. Since it's birch, I will be backing with rawhide

In my opinion if you are gonna rawhide back it ya might as well do it now
-
Birch(paper)is somewhat low in compressions ,follow Tim bakers mantra to a T is critical.your mid limbs have move considerably more.
-
Yep, I haven't done anymore tillering, i don't have any rawhide, but I did order some yesterday. Tillering is at a standstill until it arrives. I'm working in shaping and thinning the handle, and I just started shaping a vine maple stave. That should keep me busy until the rawhide arrives. That vine maple is some hard stuff compared to birch ;D

Consider making it a bendy handle...how long is it. ?.
-
It's 62 NTN, what would be the advantage of making it a bendy handle? I'm all ears, I'm hoping I don't screw up my first bow, but I figured I'd probably break or mess up a few before I get a solid working one.
-
For a 28" draw birch bow you should be no less than 68" ntn and 2" wide at the fades.
-
If all parts bend, the stress is more spread out.. Less likely to break
-
What specie's birch is it? I haven't worked with any birch but I do have a black birch bow made by planb. I don't remember the specs off hand but it is a sweet shooter.
-
Don't shape a handle until a bow is finished. That way you can guarantee the string line will go through the middle of the grip.
You wouldn't sand and varnish it now would you :) ?

If you want a stiff handle bow then I would reduce the size of it so that what you have left just fits in your hand. That way you will add a bit more working limb to your bow
P.S. If your back is pristine then you shouldn't need a rawhide backing

Yes, I agree with Marc. Use a 4 inch handle and 1.5 inch fades. Make sure the stave starts to bend at the end of the fades. and increases outward.
Then post another photo.
