Round Tractrix Horns for 1″ Drivers

While I was working on tools to turn the big ones, I turned some 750Hz horns from MDF on my own small lathe to see how this works out without CNC stuff – just using some little tricks (Like now on the big lathe, the guide pivot thing – take a look at the second picture). I put them on a pair of B&C DE25 1″ drivers I’ve got laying around here.
