I needed a boom arm for my light stand in order to float a monolight over a shooting table (DIY table I might add). I could have bought one but I couldn't justify the expense for a metal pipe and a mounting stud. Cheaper ones didn't have the weight capacity and I wasn't going to trust my monolights to a flimsy arm. So what else is there to do but to make my own.
Step 1: Parts needed
I have seen some pretty decent attempts on other DIY posts and most looked either too home made or to cumbersome. Using what has been done before and a little forethought I had a plan. A quick trip to the hardware store and photography store got me all the parts I needed.
From the photography store:
1) One mounting stud - I bought a Manfrotto dual size (1/4 - 3/8) threaded mounting post.
From the hardware store:
1) One aluminum painter's extension pole with removable screw threading.
2) One 1/4-20 thread 3 1/2" carriage bolt - sized to fit the Manfrotto mounting post.
3) Two washers.
4) One nylon lock nut - to fit carriage bolt.
5) Threaded rod coupling nut - it must be able to fit snugly inside the extension pole and allow the carriage bolt to pass through.
6) Pop rivet
