Being fairly new to turning, I sometimes discover that my set-up strategies fail me. I have a few projects put aside because of errors, because I lacked the proper chuck to mount them. Though my 3-jaw scroll chuck is quite versatile, it cannot be used in every woodturning situation. So I bought a “Super Nova 2” chuck, and as soon as I put it on the lathe, I knew my options increased ten-fold. Rather than write a review of this chuck, I will resist the tendency of some LJs who run to the keyboard and hammer out a review of a tool they’re hardly familiar with. I have no other experience with other brands of woodturning lathe chucks with which to make a coherent comparison with, and indeed there were other makes and models of chucks on the shelf which may surpass the Nova series. Now, on to my newly discovered procedure for mounting the project into the chuck: With the use of three successive hole saws, I was able to create a recessed circular ring in the bottom of the project, by which the jaws can expand and grip the project from the bottom, as shown here:
and then, using the same pilot hole, I bored two successively-sized holes, all 3/8” deep. Just a bit of cleanup with a chisel to break out the remaining waste, and voila! The recess is ready to accept the Nova Chuck jaws: The use of hole saws give one other handy advantage to turners, and that is the ability to quickly make sacrificial bosses that can be mounted to your project and then gripped by the jaws of your chuck. Once hollowed out, this lid can be turned around and chucked in my scroll chuck, and the sacrificial boss can be tooled away.
By this method I was able to salvage a little project that hit a brick wall due to mounting problems.
