My "inverse taper" or "reverse cone" or whatever it is du jour is sometimes concave or sometimes convex and it tapers to a zone of inflection (my term, although "appropriated" using a synonym by someone else AFTER I described it) and other times not curved.
Beyond the inflection zone (which I place at a point determined after corresponding with the client) the bore may be cylindrical, counter bored (back-bored at the exit, or less tapered, again dependent on the needs of the client. Sometimes it is just a straight taper and other times hourglass. It depends on what you want to achieve. Mind you, this is done by hand on my wooden models.
The entry and exit and bore shapes are adjusted for the different lengths of barrel
My bore is NEVER the dimensions of a standard Morse taper!!! OK, I do have some Morse reamers, and I use them to keep my lathe arbor spiffy.
To muddy the waters further: I designed a taper for hard rubber Chedeville(TM) models for Dr. Omar Henderson. These are CNC machined. I will not discuss those dimensions here, as I am not the owner of that copyright.
