Tillering warbow with reflex
adb:
Yes, I would definitely say making heavy weight bows is harder. Is for me, anyway.

Shoot, for me it's the opposite. For me tillering lighter shorter bows takes more skill than warbows, just because removing less wood makes for more of a difference in tiller. And I think it is easier to get chrysals or a bow breaking hinge in a shorter bow. I only get chrysals in warbows if I use a weak wood, for the most part the bows are so long is it hard to really stress em too much, despite the high weight. This is how I feel anyhow. Now it sure is physically a lot harder for me,... I need the exercise though! ;D

And that fellow sure is drawing that bow funky like. He is drawing it unevenly, mostly the bottom limb, you can see it in the arrow and the bottom limb bending more.
Edit: And with a hemp string too, cool! Don't see alot of those, must be good hemp not the stuff around here.
WillS:
I think I fell straight into the trap Del was talking about, by making the reflexed limb weaker to match the other. It certainly wasn't deliberate, and I was trying my hardest not to do it, but when looking at it on the tiller I just couldn't trick my eyes into leaving that limb alone before it was really working. If I'm lucky, and with a LOT of heat treating, this bow that was designed to be 100# will finish at about 45# which is diabolical. It will also be massively overbuilt for that draw weight, and having been pulled to around 80# during tillering is of course hugely over stressed.
I always try and take away lessons from each failure to avoid it happening the next time, but apart from the above, I really don't know what went wrong here. I'm still in the dark as to why it suddenly started bending sideways, and really surprised at how much weaker the limb that originally was reflexed the most now is.
I like to think part of it is down to using an adapted Mary Rose design on a bow wood not suitable. I know that ash works well with some heat treating, and especially well with a trapped back. But that bow on the Warbow Wales site has completely thrown me, because it breaks all of those rules and still comes out at an unbelievable draw weight.
Yeomanbowman:
Another factor to think about is density. Ash can range from .6 to .8+ SG and it makes a large difference to the draw weight for the dimensions. There's loads of ash about (at present:-/) so have another go and make some shavings!
Why not give this bow away to a young archer and build on what you have taken from this bow in mark II, and after all, it was a bow and not a load of splinters!
Good luck.
