Greg, I usually work them down slick as a baby's butt-even with the shaft. I've heard people say that it weakens them, but I don't see it in actual practice. Believe it or not, my arrows often make "unscheduled impacts" with trees and rocks when I'm shooting 3D or hunting
and so far, I've never broken a cane arrow. Never. I've splintered and destroyed loads of wooden ones, though. I've seen pics of bowstrings made from cane with the nodes smoothed down, and we all know how much stress is on a bowstring. The only time that the nodes are a weak spot is when you're heating and straightening them. So I do the major straightening before I work the nodes down, as sometimes the nodes are bent at a pretty sharp angle. After the major straightening, I take a file, knife, or more often lately, a sanding drum on a dremel or belt sander, and work the nodes down. Then I go back and fine-tune the straightness until they roll straight on a flat table without a bunch of wobbling. I don't know why anyone would want big bumps sticking out of an arrowshaft when it doesn't hurt anything to smooth them down, I've tried them both ways, and really don't see a difference in durability after shooting thousands of shots with cane. Also, on hunting arrows, I don't really want those bumps sticking out to inhibit penetration. I think the "leave the nodes alone" thing is just something that everybody has heard, but few have actually tried to test out to see if it's true.
