How about this alternative, in lieu of taking it through the house and down the stairs, build an access area to your basement from outside the house. Excavate a 16’ long by 8 foot wide sloped ramp, pour a footer, lay block up the side, pour a concrete ramp with rail track. Then, install a 7’ tall by 6’ wide set of french doors into the basement. Imbed a hoist assembly that you can use to lower your assembled saw.

Never mind, using 2/8’s as runners on your stairs would be easier.
