[SML] Mounting a projector

[David Bowman]

Good morning,

Personally, I would either use a good Rota-Loc (sp?) or spend the money on a well rated 90-deg Doughty. Here at Syracuse, we use the latter (IMHO Rota-Loc’s are a PITA to use. Totally do the job correctly, I just never have enough thumbs to hold everything to get them lined up) and I put a c-clamp on the pipe just above the Doughty for my own piece of mind (the unit is also safety cabled to the position).

I get my Doughtys form Sapsis Rigging.  They are usually here in a day or 2. I order the black, as sometimes my units are hung FOH, but that’s just my preference. Worth every penny.

Just my $0.02.

Subject: [SML] Mounting a projector

The house TD at the Fredonia Opera House just received a new video projector that is significantly larger than the former unit.  The former had a  platform suspended from and FOH pipe by a yoke with two C-clamps.

The new projector weighs about 50 pounds, is larger than the exiting platform and comes with hardware that seems designed for mounting to a piece of 1.5" pipe in the projector itself.

The question is, could this projector be suspended by a C-Clamp fitted in a hole bored in a 1.5" pipe cap that is threaded on to a piece of pipe and then attached to the projector? The yoke bolt would be lock-nutted and thread-locked to prevent loosening.

In the past, I've seen side arms for lighting mounted this way and they seemed secure.

Any thoughts on this would be much appreciated - and soon. He wants to mount the projector this week if possible.

Many TIA.
