As I was cruising around the net today I happened on a cool idea. Lathe work is something that I enjoy and am spending more on recently. One of the reasons that I got a lathe in the first place was because I needed some over sized dowels for a project a few years ago. I had been taught to use callipers to measure the material as I removed wood and that method was pretty effective but I just saw a new idea on the net.(or at least new to me).
Check out this video
If you look at the video at one minute you can see that the pre-drilled size gauge is hanging on the tail stock ready to be slide onto the spindle to check the size any time the woodworker wants it. I think that is quicker and easier than callipers.
