Admit it, you’re addicted! You can’t turn enough wood or make enough sawdust. Unfortunately, you are also afflicted by the same condition as everyone else, a lack of time.
When turning is your livelihood, you’re missing out if your are not thinking about your efficiency and it’s costing you money. When turning is your hobby, inefficiency also costs you, but often the cost is in time.
Regardless you should make the most of your time turning. If you turn much, a 4-jaw chuck is the way to go. A clean tenon or recess on the bottom of a block and your off to the races. Ever cut a tenon that is too big or too small for your chuck? You end up rechucking between centers to try again?
Save yourself the aggravation by making a guage for your chuck. These are easily made using a piece of scrap 1/4 ply. On one side, cut the minimum tenon and maximum recess, the other obviously has the reverse.
Make the most of your time and make the most sawdust. The 15 minutes it takes to crate a guage will be well worth the effort, forever eliminating the need to double chuck.
Affix a magnet on the back, used to store this on the leg of the lathe.
