On 3/2911 I wrote about how I made my first cone mandrel. This is an update with a SketchUp version of the plans.
The concrete filled base was originally designed to fit a purchased mini cone mandrel. Subsequently, I’ve used it to hold several other mini cones, a ring roller and just about anything with a tang of appropriate size.
