tillering a flatbow question

[John Malone]

Merry Christmas Guys. I have an oak flat bow laid out. 72 t2t 1 5/8 wide it tapers to .5 at the tips for now starting at mid limb. 10 inch riser area and its still a full 3/4 thick so my question is when I start tilering this thing will I end up with lots of belly taper? I'm looking at Sam Harpers build along and he basically has it 3/8 thickness the entire length to start. Doesn't say were most of the wood removal takes place though. His is also #45 I'm looking for something heavier say #50-55. Should I start by removing wood evenly down the entire length until it starts bending and go from there? Also if anyone has a pic of a properly tilled flat bow at full draw that would be lovely. Any idea how thick the average oak flat bow ends up in the 72 inch #55 pound range? Say 5/8 1/2 3/8? Just looking for an idea of how it will generally end up so ill know how best to start. Thanks Guys.

What I will do is scribe a line down both sides of the limbs at about 5/8" from the back and taper the fades down to that line from the riser. This will place the riser above the plane of the limbs then I start tillering . It will probably be thinner than that but this will get you in the ball park.
  Merry Christmas to you too John.

Thanks Pat Merry Christmas to you and yours as well. I remember you telling me that from the last one about risers and planes, I usually only make mistakes once. Usually?

Make sure and use your "GIZMO".

I made a pretty "GIZMO" from a scrap piece of cedar.
It has way better vision than i do.
 Thanks Guys.
