I have that bow bending pretty nice for one made out of junk wood, in public, while answering questions, then splitting it twice and having to wrap it with dental floss. I have had it strung up a dozen times, pulled it as far as feels good and shown it off like a proud papa. So, I guess I should take some pics and post 'em here.
As for even-ness, i have spent a lot of time throught the years bending violin, viola, cello, dulcimer and mandolin sides, and didn't have any trouble making the ends of this bow bend the same. Now, the next stick could be different.....wood is wood.
But, the process runs slowly and without instant excitement, so more or less bend can be made and propeller pulled out of it as you go.
