I have a Dewalt circular saw. It's probably about 10 years old. I'm
working on a design for a panel saw, so I started analyzing my saw more
carefully. The base plate of the saw appears to be warped. If I put
it on a flat surface, one corner is up by about 5/64" (actually about
2.25mm). That seems unacceptably warped to me and probably explains
why the saw doesn't seem to cut that well. Are my standards too high?
Anybody else had a problem like this? I was considering flattening it
on sandpaper like a plane sole, but that seems like an awful lot of
metal to remove. Any other ideas? I have considered trying to bend
it, but it doesn't seem like that will work.
