Step 5 TAPE THE CROSSBAR

We will be attaching electrical contacts to the crossbar. so it must first be insulated with gaffers tape or duct tape.  I recommend using gaffer's tape, which is available at most photography stores, arts stores, hardware stores, or online.  Make sure the crossbar is free of dirt and oil, which the tape will not stick to.  If your tape is still not sticky enough, you can reinforce it with a few dabs of superglue.
