I've learned a lot in the past few pipes, especially about getting the shape right. Most important lesson recently: don't rush the sanding. I'm used to casework in which sanding is a quick last step on the way to the finish. (My smoothing plane and card scrapers make sanding almost unnecessary.) On a pipe, though, sanding can take nearly a third of the total time.
