Jason,
My only concern about your base is that it raises the saw much higher than the HTC bases. My modified HTC base is designed so that the saw is only 1 1/2 inches higher on the base than it would be sitting on the floor. If you are a tall guy, then this is probably better for you. I'm 5' 8" and my 1980's Unisaw is about the right height without any mobil base. The last thing that I wanted to do was raise it 3-4" with a base like yours. It even took me a while to get used to my Unisaw after I raised it only 1 1/2" with the HTC base.
