Great write up, pics and the vid made it real clear, Doug. Honestly, I've never seen chips that good from a New countersink...that is Impressive...made it look like shaving butter with a scalpel! Am curious how well it cuts CRS or harder material. Love that you take that simple approach to your designs and versatility of a tool and would never have thought about the cam idea for that operations, let alone how much of a cam.
Once again I learned a bunch in 10 minutes and ever grateful for you sharing your work and the forum! Thank You!
