The horn nock will just cover the end of the bamboo when it's all finished. I put on a slack string and flexed it while looking at the reflection in the patio doors. It felt strong enough and looked reasonable. I spent some time checking limb thickness to take out any thick spots so that it slowly tapered towards the tips.
I tried to mark a centre line, but it's tricky on a curved bow, I need to reduce the width along the whole bow to stay within the 5/8 thickness/width ratio of the longbow definition.
I wish I'd had thicker belly billets so that I could have had a bit more taper, but you have to work with what you have.
The brief was 40# maximum, so I can always drop a few pounds to get the tiller right.
There was a long discussion on Primitive Archer about different tillering methods. I like to get it braced ASAP but one guy said that if your short string just slips onto the bow the draw weight/draw length figures actually line up pretty well with the finished product. If that's right then I'm about 40# at 25" which gives me some elbow room to get it right. I've already adjusted one limb to get the 5/8 ratio and a better string line, but I've done enough for today. If I'm short of draw weight I can always come back in an inch on each nock (not that it will make much difference).
First I wanted to see it on the tiller. It looks ok, but most bend is on the inner limbs, the tips need tapering in width, which is what I'll do next. Slow and steady, I've done probably 80% of the physical work on the bow, but I'm still only half way there in terms of tillering.
