Converted my saw from 3600 rpm which translates to 100 mph tip speed to 1750 rpm with variable speed below that. It's a much nicer saw. Safer, quieter, makes bigger sawdust and doesn't blow it around the shop as much so dust collection works better. Cut quality is as good with less risk of burning. It cuts a little slower so it has cost me 3 or 4 minutes this year.
