I've got mine converted to a QCTP so all I have to do is set the blade in a mount upside down and then it goes right on when I need it.

Hey Dan, if you don't have a tangential (diamond) tool holder you should look into buying or making one. I'm truly stunned by how well the one I just made cuts and the finish on aluminum and steel is the best I've ever seen from my lathe. I think a fella could upgrade from a collection of carbide tools with a few TTHs and be out of the insert buying market to boot.
