[TowerTalk] How to disassemble a boom?

[Scott Bullock]

Pulling works, pb blaster, and hitting it with a propane torch to burn out the oxides works usually. Spray from all different angles and do one joint at a time. 

This is where preplanning and using noalox makes life much easier :)

The sections should easily pull apart although you might have to hit it with some PB blaster and let it soak. I had several boom sections that were undersized, or the inside piece was over size. Those are permanently joined.  So, unless they were mis-sized the clamps should not take much force.  Just a cable loop anchored on opposite sides with the pull from the middle of the loop.  Keep it simple and if it appears to look like it's going to take much force, stop and reevaluate.  You might need to tap on opposite sides with rubber mallets to loosen things up. Do not use metal hammers. apply hits to opposite sides at the same time. Do not hit hard.
