Worked fine and NOW this started happening? Or it's a new saw and this is the first time you are using it?
Assuming it has worked fine and just started doing this, it might be the centrifugal...
Because utility distribution tends to climb above their normal range at night when large loads shut down. They have regulation, but it is not instantaneous. Also, if you have a motor designed for...
As an Electrical Engineer (who happens to love woodworking), I read this with interest. It's especially interesting to hear "electricians" repeating the myth that 240V "saves energy". Watts = watts =...
I used a slab of redwood end grain about 3" thick as a coffee table. Yes, it cracked, but that didn't really render it useless, I consider it part of the "character" of the piece. It's been this way...
