In theory, making nose cones and transitions is easy - you spin a balsa block in some sort of power tool and use chisels and other sharp objects to carve the spinning block to the desired shape. The tools are not hard to find or acquire - Duane has one of those nifty 5-in-1 shop tools, but I have known people to use electric drills for small cones. The main requirement, as in so many things, is patience. A steady hand is also necessary, which is why I am not too keen on making nose cones - I do not wish to do the klutz squeal of "Whoops, there goes part of my finger." But based on my observations this weekend, a fearless, sure-handed individual can make a BT-80 size nose cone in about 30 minutes, including frequent stops to make measurements and check shoulder diameter.
