The message
from Stuart Noble contains these words:

In table mode the fence is unstable. I wouldn't be
without mine, but accurate it ain't.

My Rexon table saw is susceptible to sawdust in the fence tracks. It's
fine it you keep blowing it clear and wipe the accumulated resin off the
rubbing buttons but if you're not careful it starts to slip out at one
end when dirty.
