My most fun tool to use is the router table setup - 3hp router, lift, and Incra fence. Man I love that Incra fence. I love its precision and functionality and routing is just plain fun!
The Smoothest and most satisfying tool I use is my cabinet saw. I think anyone that uses a finely tuned table/contractor/cabinet saw knows exactly what I mean here. Cutting perfect burn free straight wood with zero effort is simply satisfying. Learning the techniques for using this saw has made it my favorite Good tool purchase.
Glad its my shop I am responsible for - I only have to make me happy.
