New Yew bow build along
FilipT:
Beautiful bow Ian. I downloaded video so I could have it at any time as a reference for my future longbows.
I wanted to ask you something. I am starting now with building warbows and I decided to make somewhere 70 - 80# longbow from hazel to be entry into whole heavier bows build. I used dimensions from Norwegian Warbows website and bow barely bends at floor tiller, more like one limb bends nice and other doesn't.
I am curious as to why that is, as I saw you saying multiple times, how when you make longbow according to dimensions of, for example, MR bows, you get almost tillered one, that just needs minor adjustment on tiller and is even ready for brace before putting it at tiller.
Ian.:
What I go by is the MR dimensions with wood I know to be very similar but mostly I weigh the wood and make sure the mass is right for the bow weight I want to make. If you don't have the 'Mass Calculator' I can easily email it to you - get my email address from my website.
When you have the right mass of wood to make the bow weight you want and you get the stave very close in taper and size so that it bend well first time then yep, just brace it and tiller quickly.
The caveat is that it took me many dozens of bows to be able to get the tiller almost perfect from the roughing out stage.
FilipT:
I could tell you for a fact that my current bow build has been both tapered in width and thickness with calipers, meaning, its almost perfect according to measurements. That is why I was wondering why does limbs not work evenly in floor tillering. I don't have yet wall tiller so I don't know how it really bends but I am not satisfied with floor tiller.
So the key is lots of experience and bit of the science. I would really like to get my hands on that calculator. Thanks for offering.
Is it "sales@bostonbows.co.uk" your mail or you mean some other?
Ian.:
Yeah that's the email - I wasn't going to post it on PA as I didn't know if it was allowed.
FilipT:
I don't want to open new topic for my question, so I will put it here as its about mass calculator. What should I put into this variables:
- nock position (+ reflex, - deflex)
- handle (non bending)
If I tiller a longbow, do I put "0" into handle as everything bends? If I tiller bow with non moving handle, do I put 8" in it, as I make handle length 4" and 2" fades from both sides?
What means nock position and reflex, deflex in it?
