My G0555 has a 1 hp motor. I have cut quite a bit of Osage Orange at the 6" max using a 3/4"X3tpi Timberwolf blade. It cut well but I could have had problems if I forced. Patience was required. Personally, I would not add the riser block. I believe a
14" bandsaw is designed to do what a 14" bandsaw is intended to do and adding the riser will stress beyond that intention. BTW, my next resaw blade will be a 4 tpi as cutting thinner pieces, like 1" caused catches. Not good.
