Adding Your Camera
Once you are done creating your jib crane, you must bolt the camera to the base. You should have created a small hole in the base of the metal. If you didn't do this before you attached the metal section, you can still add it after. You must use a metal bit that isn't too large. If you do make the hole too big, use a washer to decrease the size of the hole.
Bolt the camera to the jib crane. Ensure that the camera is tight before you start moving it around. If your camera falls off of the jib, you may have to invest in a new one. Also, only use modern mini DV camcorders. Older camcorders are extremely heavy, and your new jib may not be able to handle the weight.
If you do want to use an older camcorder, you may want to invest in larger wood and metal pieces. This will make it heavy to carry the jib, but the heavier jib can also handle the weight of the camcorder.
Another option is to carry the jib with you as opposed to using a stand. You can do this by making the jib smaller. Basically, cut the wood pieces in half to make it lighter.
Try out your camera jib crane for a few practice sessions, and tweak it if necessary. You can always remove the stand to make it easier to fold down and take with you. And, you will always know how to build a jib crane if you need another one.
