Hi, Got a question about my Nova Cole chuck. I was using it to turn off the spigot and sand a small bowl and was wondering about the RPM. I think that the instructions said no more than 600 rpm. When I turned the spigot off I run the live center up against the bowl and run it about 800 rpm. Was this too fast? Another question kind of on the same subject. I was cutting rounds off the chunk of Elm that I was going to use (it's been curing for about 10 years) with my bandsaw (cross cutting) the blade was a 1/2" by 4 tpi, the round was about 8" in diameter anyway the blade went though in kind of an "S" pattern not straight up and down. Do I need to use a wider blade say a 3/4"? Thanks, Jim
