I love the Little Crow Gun Works Worlds Finest Trimmer 2 (WFT2), but it can make for some sore fingers after a while. I'd read about some reloaders using Drill Presses, but setting the case length means resetting the depth for each case type.
So I got a Forster Power Case Trimmer and Colletts and mounted it to the Drill Press to hold the cases. Then the WFT2 goes in the Chuck. Now I just have to pop in the new Case Adapter on the WFT2 when Trimming different size cases and the length is set. Much easier on my fingers, and pretty fast Trimming. The brass shavings don't clog up the WFT2 either.
