Boom Crane Pulley

Step 5 Assembly

Now we put it all together. Put a bolt through the second hole on the boom pole and one of the ends of the support pole. Put one washer on each side of the bolt, and one in between the pipes. Tighten it, and then add a second nut.

Slide it out over the edge like before, and the lift up the support pipe and line it up with the hole in the railing. Once it's good, put the bolt through the top, sandwiching washers in between. Tighten it, using two nuts.

Since the support pole is pulling from above, rather than pushing from below, you might consider steel cable instead. You could affix the cable to the railing without drilling holes or worrying about angles.
