Hi all,
Was hoping to get some advice in regards to the tillering of this osage bow I've been making.
I know one side is different than the other, but no idea where I should remove wood from! Or if the side that's bending more is bending correctly or also needs some wood removed.
Any help was be much appreciated ! Thanks
-
We need an unbraced picture, please :)
-
And a photo of the back profile. Eg. how it tapers in width. Different width tapers need a different tiller.
-
Thanks people :)
-
seems to me like its bending more near the fades. dont do anything though!! thats just my take! im not amazing at tillering
-
I'm thinking a couple or three scrapes mid limb on the left unless that's your lower limb and you want it a bit stiff. I think I see a flat spot on the unbraced right limb that is reflected in the FD so I think that's OK. The vertical mortar lines are messing with my head. :D See what others see
-
It looks like you have a lot of violated rings on the back.
-
Thanks for the help :)
Any other opinions?
Yeah I'm sure that there is violated rings haha. I've fairly new to to this so chasing a ring isn't my specialty. I've more gone the sand with low grit sandpaper until its really smooth method haha.
Can almost draw to 28 inches though and it hasn't broken or cracked - yet haha :)
-
whoo!! that back looks rough! im glad its holding up though! looks like a challanging peice of wood after closer inspection.
so its almost at full draw? can we have another pic??
-
I'll take a clearer photo of the back if you like! Yeah definitely has a bit of character haha.
The initial pictures are 15 inch draw and 20 inch draw. So you'd like a picture of it drawn further? =)
-
yeah!
-
some photos of the back, and at 23 inch and 25 inch draw :)

(Sorry about my shadow haha)

Have you heat treated the belly at all? What poundage is it drawing and what are you aiming for? Please don’t take this as gospel cos there are many others with a far keener eye than me but my feeling is that it is a difficult tiller to fix ... if you try and get the limbs to bend the same shape you will have to balance the other limb with a lot of wood removal and your poundage will go down a lot. If you haven’t heat treated, I would be inclined to try and heat treat the limbs back into some sort of reflex. It seems to have a lot of string follow if that is the unbraced profile? If it was me, I might sinew back it to deal with the violated back, put it aside for a while and then come re-tiller it when you have more wriggle room. Osage likes a sinew back, heat treating and is quite forgiving, and that is a nice character bow which you have put a lot of effort into. My feeling is anything else you try and do to even it up will bring it in way under weight.

Currently its 55 pounds at 25 inch draw. I have no real desired draw weight so that's not too much of an issue. Haven't heat treated it at all. Which limb do you think needs heat treating and what's the best way to go about it?
Thanks heaps advice is much appreciated! :)

Sorry forgot to mention there is definitely some string follow, was too impatient and probably didn't give it enough time to dry!
