tillering advice needed (w/ pic), and other questions

[Predictable]

i know... it's a poor excuse for a "tillering tree", but it was fast. i'll be making a better one soon.
in the picture below the tillering string is the shortest long string possible (meaning it has very very little slack, but it isn't tight).


my other questions:

1. the bow is 63" n2n and my drawlength is 28", i feel like i've removed so much wood but it's bending only to how it looks in the pic above. the tips (right before the tip overlay fades begin) just over 1/4" thick. is this normal? im afraid its too thin, it doesnt feel flimsy, but it's starting to worry me.

2. what should my next step be in the tillering process? (i have not braced it at any brace height yet).

The length is short for a 28" draw. You should be around 66" ntn minimum.
I'd get the near handle wood moving more. It gets hard to pull without the entire limb bending particularly on a short bow. That's probably what you are noticing.
You didn't mention the draw weight you wanted.
What I do when I feel the limbs are getting too thin is to begin to narrow the stave.
You need a plan as to when to string it up with the short string.
This gets me in the ball park.
I long string tiller out to 10" looking for good limb bending.
I also look to get draw weight plus 5# at ten inches of pull with the long string.

i cant believe it! i completely forgot about that length of the bow is determined by drawlength. i guess this will go to my little brother then.
this is my third bow build, first broke, made a second one, and started this one randomly last week. guess im going to buy some more wood tomorrow.

What type of wood is it? Stave or board?.... Brian

Next step is to round all your corners/edges well and blend the riser into the working limb.
Then get it braced at about 1 inch high, slowly draw it and then take a picture of it low braced and drawn.
We also need to know the width taper to tell you what the tiller is like.
