This is such a great addition to the 14 inch Jet bandsaw that I'm surprised Jet doesn't just make it standard on all their 14 inch saws.  I was able to install it by myself, and I'm an old guy.  I rigged a rope from the ceiling to support the top arm of the saw, disconnected the bolt, and lowered it to the floor.  After that, the installation goes very easy and straightforward.  Putting the top arm back on was the opposite of taking it off, but be sure that you can tie off the rope so you can use both hands to tighten the bolt.
