If you are talking about the DeWalt stand, don't do it! I am the scroll saw instructor at the Woodcraft store in Ventura, Ca. The store installed locking casters on the demonstration saw so it could be easily moved around the store and shop. Even with the wheels locked, the Stand wobbles and is top heavy. Also it raises the saw table to high for comfort. That may not be a problem if you are tall, but at 5' 10", it's to high for me.
At my shop, the saw is permanently parked in its place. If I need to move it to clean, I can easily pull it out.
P.S. The DeWalt stand has three legs, one in back and two in front, so the solution young_scroller made would be impractical.
