Pool cue+chains+(3-6) bowling balls (add a power drill and some bolts) and you got 1 bad "cat-o-nine tails"
I am sure (sarcasm) that they will allow a few of the parts, but are unwilling to let you "compatmentalize" such a mideval weapon of terror.
Kind of like a laptop...has the timer, the power source, the wires, and you can bring it...its the other 2 pieces of the IED that you can't bring...clearly the pool cue is the "key" piece here.
