Last week I found a piece of wood perfect to whittle and the first thing that popped into my head was to carve a pipe. So I got to it, had an initial design in mind, but found out there were some hollow spots in the wood, so I couldn't get it exactly as I wanted it. It's still not finished completely, I will do some more shaping and maybe carve some detail into it, also it isn't completely drilled out because I can't find the charging station for my drill and the battery died on that. I did leave a knot in it for a carb, which should hopefully work out well. Overall, I like it, not just a cylindrical pipe like everyone else makes out of wood.
I've actually been meaning to for quite some time (it would come in very handy for my Rubik's cube modifications) but I seem to keep spending the money on other things first that I tell myself I'm saving for a dremel.
