Just made a birch dish for a granola guy, and while sanding, I thought the dust was throwing a bit more than usual. Normally I can get 90% or more with the DC down and away. Then it hit me - I had been using a pneumatic sanding drum on the lathe on Monday, and I had actually changed speed from
500 to 1000. Two days - bowl, dish, cup-and-saucer and a box on high speed. Can't remember the last time I actually did that, though if I recall correctly, it was when hollowing with the scraping tools.
All you folks with variable speed may laugh, but I just opened the cover and moved the belt back to 500 rpm. That way I can still use my non-HSS tools....
