Thanks, George and Ron :)
I suppose it only makes sense.
Is there a 'standard' taper for wheels?
(The nice thing about standards is that there is so many of them to choose from... ;)
Does it determine the radius of a curve that a train can negotiate?
So, do 'our' ;) model train engineers turn tapers on their train wheels, too?
Does the wheel taper determine the max/min curve that a train can negotiate?
Inquiring minds want to know...but don't want to do the math to find out.
