going with 1" keyed, and taking the 50 sprockets down is probably your best option. watch out with the lower grade steel pre-keyed shafts- they usually have a bow in them from the key cut. on the smaller sprocket sizes (i think, but not sure -- it's right around 19T and under) you will also have to shorten the teeth and recreate teh tip angle on ALL sides of the tooth. a file works fine for adding the inside angle back after taking them down. A lathe or mill is definitely the way to go, but i haven't noticed any unusual wear yet.
