Step 3The Support Pole
Now you need to decide how long you want your crane to extend out. I'm not a mechanical engineer, but i can figure out the further the boom is from the building, the forces compound dramatically. But you don't want it too close, or anything you lift will be dragging along the wall on the way up!
I chose to go about 4 feet out beyond the wall.
The support pole is a little bit trickier. Since these conduits come with threaded ends, i didn't like that so the first thing i did was cut off one of the ends.
I used a compound miter saw fitted with a 7" metal cutting blade. Once again, have one person holding the pole. Cutting this thing produced a TON of sparks! In the future, i would wear gloves while doing this, as the sparks kind burned when they touched you.
It should go without saying that this step DEFINATLEY requires safety goggles!
Once the end is cut, i used some sandpaper to smooth out the outside & inside of the pipe. Now we need to drill our first hole. I drilled it about 2" back from the end of the pipe (the nice clean end). Once that was done, i needed to determine the length. I put a bolt through the hole and the second hole on the boom. This is just for testing! I slid it out over the edge and once i was happy with the distance, i made three measurements: the length of where to cut the pipe, the optimal place for the second hole (about 1" from the end), and also where to attach the pole to the railing.
Once we were all measured up, i pulled it back in, and disassembled it. I lined up the support pole in the saw, cut of the other, and sanded it.
We now need to drill the second hole in the support pipe.
Remember, it has to be at a 90 degree angle from the one on the other end!
If you marked it well in the last step, you should have no problem.
