Yup, very nice job on a tricky stave.
I'd leave that knot as it is.
I'd probably have cleaned it out and filled it while it was a stave, but it would have just ended up as a tiny patch of clean Yew, whereas you've got a conversation piece with that one.
I think it's swings and roundabouts, too much cleaning out can disturb the way the wood has grown round it, too little and you have a hidden pocket of rot.
With that one you can see what you've got.
You can tell the compounders that it was where you were struck by lightning at full draw
or it's where the devil himself tried to snatch the bow from you, but you just spat in his eye and grabbed it back
I got an E-mail yesterday from a guy I made one for over a year ago, its had a crack/big splinter lifting on a knot (first shoot afer having been put away over winter). Luckilly it was spotted so it's an easy repair job. My heart sank at first.
That's the prob with wood, it never stops moving, even stuff 30 years old still shifts.
Great tiller on that one...
Only thing wrong with it... it's not mine
