I still have not figured out what those inserts are exactly. Anyways, yeah, that saw looks pretty capable, but my question is why not use a radial arm saw instead? It has ripping capabilities, miter capability, bevel capability, even has a built in router (not very good for it though) and it's 2.5-3HP. Although ripping isn't the easiest thing to do on the radial arm saw as it is weird to do it sideways, it is still very capable at making almost any cut you want it seems. Is there any reason I shouldn't just get that?
