Like Billy I too made my own base with lockable heavy duty casters - big mistake, there was too much movement swaying from side to side when cutting anything big. I took it off the base and firmly bolted it down. Then I used my base (slightly modified) to mount my 10" by 6" thickness planer so I could move that around the saw, that was more steady as all the weight is lower down, so it's much more stable on it's wheels. hope that helps.
