After ripping some 8/4 Ash, I am wishing I had gotten the 3HP Sawstop PCS. At the time, the price was just more than I could do and I wasn't 100% sure I wanted to keep doing woodworking long-term. I seem to remember reading somewhere that it is possible to upgrade the PCS 1.75 to the 3HP motor. Has anyone done this? If so, what all gets replaced and what was the cost?
