If the jointer is removed from the base, a couple of strong guys should be
able to negotiate the stairs. I hope you enjoy your 8 inch Yorkcraft as much
as I enjoy mine. The YC-8 is a very under-rated machine, mine was way out
of adjustment when I got it. A dial indicator and a little persistance have
brought everything into line. Now it makes flat stock out of warped and
straight edges out of wainy.
