This will be an attempt to detail the steps I take to turn a hollow form. The wood that will be used is from some walnut that I was able to get early this year and has been stored in an old barn. This is the block of walnut after I have chain sawed it to rough shape. The piece is 14 inches across and 13 inches high.
I have circle templates in various sizes made from 1/4” hardboard that I use to size my blanks before they go to the band saw. I used a 12” template nailed to the walnut block and cut it to shape on the band saw. This hollow form will be turned side grain.
From the band saw the blank is ready to be mounted on the lathe. I use a heavy duty two flute drive that is held by my Nova super chuck. I have center punched both ends of the blank to make it easier to determine where to mount them between the drives. If necessary I will move the blank around a little to get the best grain orientation.
The next step will be to rough out the shape and prepare a tenon on the tail stock end that will allow me to mount the blank in the Nova chuck. Time to stop for today, I will start turning tomorrow.
