Greetings Bob,

I have had the G0555 with the riser block for over a year now, with no
complaints at all. It is used almost daily and the only thing I have
ever replaced is one of the guide berrings that froze on me after
getting a piece of alabaster wedged in just the wrong position.
It runs smooth as silk and have never experienced any sort of setting
changes despite the fact that it is often called on to handle much more
than it was designed for. While I like Jet tools and have several,
grizzly has a real winner in this one.
