There is an excellent book out there called "Traction Drives: Selection and Application" 1/2 the book is gear-less fixed ratio systems, and 1/2 are CVT or IV T systems. These designs typically have pitfalls above 10 hp and start requiring exotic designs, traction fluids, and controls. CVTs have really started to make a comeback in the automotive sector, but we are also learning about some of their disadvantages too. I am a huge fan of CVTs, but I also understand that for many applications they are not terribly practicle. This is a great off season project, but would probably hinder development during the actual build season.
