|Tip: Waste Blocks|
Instead of cutting waste blocks using the bandsaw or with a hole saw, I glue scrap boards together in layers to form lengths 3" thick by 20" long (8 cm by 50 cm). I turn the lamination to a cylinder of a diameter that will fit my chuck. I cut thicknesses as needed, using the bandsaw with the cylinder safely held in a V block.
I generally use a section that is 2" (50 mm) thick so that the project is kept away from the chuck, but you may wish to have the bottom of the turning blank rest on the shoulder of the chuck jaws for additional support.
Because I am gluing endgrain, I use five-minute epoxy to glue the waste block to the turning stock. It is a nice way to make use of bland or damaged wood.
