Well I cleaned the WWII and have been using more downward pressure as suggested
and it did start producing a cleaner cut. My saw is a left tilt which it seems
allows it to move up and down as suggested. Either way I want to thank everyone
for their help.

I have been cutting some oak with a Delta unisaw and the blade set to 45
degrees. The edges don't seem real smooth at 45 degrees but are smooth as glass
at 90 degree. I'm using a WWII which is about a month old. The cuts are along
the grain and seem to be tearing along the wood fibers. The poplar wood I was
using before seemed very smooth at 45 degrees. Any suggestions.
Thanks
