Re: Side booms rigging

Aside from the other advice provided, there is an ANSI standard for this 
practice:

ANSI E1.15 - 2006 - Entertainment Technology--Recommended Practices and 
Guidelines for the Assembly and Use of Theatrical Boom & Base Assemblies

ANSI E1.15 gives advice on boom and base assemblies, simple 
ground-sup****t devices for lighting equipment and accessories. If the 
assembly is tall, not plumb, loaded unevenly, or likely to get run into 
by stage wagons or performers, there is substantial risk. This do***ent 
offers advice to lower that level of risk or eliminate it.

You can download it for $ 15.00 ($ 11.25 if you're an ESTA member) from 
the ESTA Foundation website --> www.estafoundation.org. Browse for it by 
do***ent number ANSI E1.15-2006.

Cheers!
