Ok, right.
I lightly filed the ridge off the nodes (including some light use of a round needle file to clean up the slight groove by the lip), leaving the main smooth swell of the node.
I scraped carefully with a cabinet scraper until the rind was gone (it's pretty obvious as you go through the rind) then 120 and 240 grit wet & dry paper, with Danish oil to finish.
The actual Boo was taken down with a freshly sharpened plane aiming for about 1/8 at the grip 1/16 at the ends and then cleaned up on the belt sander.
On the finished bow the edges are well chamfered to blend in.
BTW I've narrowed that last 7" of the tips today as they looked a bit fat and I was slightly dissapointed that it was the same speed as all my other 50# bows, I'd been hoping for a bit more!
