I’m getting into segmented turning, and was looking at various for centering rings during glue-up when I found Lloyd Johnson’s ’Stomper’.
The ‘Stomper’ uses a set of Longworth-style plates with a spring-loaded shaft to center rings.
You can purchase a ‘Stomper’ from Lloyd Johnson’s website, but he also (very kindly) gives detailed instructions on making your own.
I made my Longworth-style centering plates out of two plastic cutting boards from Walmart. The spring-loaded shaft is made with parts of a pop-up sprinkler, a schedule 40 PVC pipe and cap that I got from Home Depot, and a PVC table cap I found online for under $3. I mounted my Stomper on a plywood disk with T-nuts and #12 machine screws so it can be easily disassembled for storage. I turned the 4 buttons on the Longworth out of scrap and used T-bolts in the routed arcs and T-nuts. The weight that puts pressure on the stack is a 10-pound weight from a barbell set.
