I have kept an old issue of wood magazine handy for years and finally got around to building the mobile TS/routing center. Not quite finished but almost.
The general idea is to build a sturdy router cabinet and a cabinet for the saw to replace the flimsy steel legs of a contractor saw. The whole thing goes on a reinforced platform with casters.
Well...,
The added mass of the cabinet and the sturdy cabinet have really made the saw run smoother. I didn't pull out a nickel but I'm fairly sure it would pass the test.
Here is the link to the plans (not free but has picture)
Now I know why the pros spend all that extra money for the 'big boy' saws.
