I bought this because I have an older Unisaw which can be difficult to fit into one of the other bases.  Let me way that ripping down wood to fit into the base was fairly easy (because of the aforementioned Unisaw).  However, the base does flex some because of the use of wood when popping it up.  I think I would have been better off using some 1-1/2" square tube instead of wood.  Probably would have ended up stronger and it would have been easier to acquire for me.
