For some time I’ve wanted an easier way of reverse mounting a bowl for finishing the bottom, and have seen several options. Seeing that you can build several of these options, I knew that was the route I would take, as I could not justify spending around 100 bucks for a set of jaws.
I’ve considered the Longworth chuck and the donut chuck, but recently I saw some homemade jumbo jaws for a scroll chuck, and thought I could make a set of these for my Talon chuck.
