I have several of those sheet metal stands like Sears sold with their radial arm saws. They have 4 flimsy sheet metal legs and the darn things flex and wobble terribly. I have cut some 1x6's and bolted them across the legs, about a foot above the floor and added a shelf and that does stabilize them, but it is a lot of work. There must be a simpler way. I have limited space and need to move some machines around to conserve space. For the router table and the table saw, they make so much dust, that I try to move them out doors to use them. Negotiating that little hump at the threshold can get scary if the stands are not rigid.
