Is there any way to do a sloppy job if you can't get to a mill?
The Machine shop that donated work for our team last year did it with a wire burner. He was able to cut the proper hole for a globe shaft in a 9 tooth #25 stainless sprocket, that started with a 1/4" bore. We had no issues with that sprocket hope to visit him again and get another one or two made for this year.
