Now that you mention it, mine was a little wobbly on the mobile base. So I tipped it all the way down onto it's back, bolted the mobile base to it and tilted it back up. Mines a little lighter, but wouldn't take much help.
Back when I tiled the floor of my workshop, I needed a way to move all of my heavy tools, and many of them were over 1000 pounds. Even though I normally don't need my tools to be mobile, I decided to go ahead and put a few of them on permanent mobile bases. One of those was the bandsaw, so I could keep it in a corner for most of the work it does, but still be able to pull it out to resaw long stock. The other big-ticket item one was my 6-foot lathe that is so heavy you can barely move it, even just one end at a time.
However, at the same time, I wanted these tools resting firmly on the floor when they were stationary, especially the lathe. So after doing a lot of research into mobile bases, I decided on getting the
Vega Machine Mover mobile bases. When they are not being moved, the metal frame underneath the tool is resting completely on the floor, and the wheels are not touching the ground. The bases are rock solid when stationary, and you use a separate tiller wheel to tilt the base and allow the wheels to touch the ground.
Vega Machinery even custom made an extra long Machine Mover specifically for my lathe.
Because the bases are modular, all I have to do to assemble a base under a machine is tilt the machine just enough to get the 1/8" thick corner bracket under each corner of the tool. I can also mix-and-match the connecting beams. That is what permitted me to use just the 3 machine mover sizes I bought to relocate all of my tools. The heaviest tool is the wide belt sander, and I can't even drag that across concrete, let alone move it across tile without damaging the tile. So I temporarily installed a mobile base under the sander so I could move it solely for laying tile underneath it.
