the bow has been worked down to about 1250 grams which is about right for the weight I am going for.

I've never heard of reducing the stave by weight. Is this in liu of floor tillering? Is it similar to Badgers "Mass Principle"?
Ian.:
It's exactly Steve's mass principle, with some alterations based on experience, I've adjusted his formula but it's very accurate for longbows. My process is to get a stave roughed out, do lots of measurements and checks then weigh it and this forms my initial tillering. I never use long strings, as you can see from this I've fitted the knocks before even bending it once. I'm sure this is how bows would have been made 500+ years ago.
Ruddy Darter:
Nice work Ian, looking great so far. Enjoying this thread 8)
What sort of bow length do you have or aiming to have to go with that weight and draw?
Ruddy.
Ian.:
Ah that's what I forgot to say, it's 81" long and I'll keep that as the final length. Aiming for 150 @ 30". Ideally the physical weight should be 1150grams but as long as I get it to that physical weight after 20" then I wont do any damage to the bow.
Knotty:
A little heavy eh? 😉
I wish I could pull at least 80# haha
