Would anyone know of a good tutorial or guidelines on offset turning handles with a triangular form? At the 2015 symposium I got hands on with David Ellsworth's tool handles for Robust and they were pretty darned sweet. I'm thinking a smaller version for screwdrivers etc.

Would the difference be because of the high oils in Cocobolo then Ebony or maybe even how high oils in Lignum vite?

Or would the oil allow it to give alittle bit more then Ebony?

I went and pulled several species from the wood database and compared density to both Janka Hardness and Crushing Strength. Both hardness and crushing strength are proportional to density - the higher the density, the harder the wood and the harder it is to compress the wood. There's some irregularity around the 0.55 to 0.60 density range, but the trend is about a straight a line as can be drawn from the data. In my case, cocobolo has an even higher density than ebony, and it's very hard. What I have learned from this discussion and my research is that I am better off either kerfing the tenon or grinding off the wings and using epoxy to set the shafts, or both. Both are acceptable methods, since they both achieve the same results.
