Hey all,New poster on the site and hoping y'all can help me out.I'm currently TD'ing the Dolphin Show at Northwestern University - "Hello, Dolly." The designer wants to fly two different clumps of objects - foam dress forms and parisols. I've attached her AutoCAD drafting. Long story short...

Hi all,Why are the doughty style of boom arms become dubbed 'derig arms'? Where did the term come from?Just curious.

I have three catwalks in my black box that run parallel to one another. They are fantastic to hang from, but there are no hang positions (grid or otherwise) between the catwalks, which leads to inadequate focus positions. What I'm hoping to do is to run a standard batten pipe across those spans...

I'm going to get blasted for this, I just know it...Anonymous hands-up of how many of you are using harnesses in your genie or vertical 'stick' lift? Not talking boom or scissor lift. Within the 20-25 foot range.What ARE the actual regulations on that with OSHA or ANSI? (I haven't had...

Random question: I was on a site tour of a new facility the other day that's still in the concrete-pouring phase, but when looking at the stage house I was told they are preparing for a rigging system that will allow the arbors to pass below stage level into a basement pit.I've only ever...

Hello, For an upcoming show I am planning to fly some powered speakers for center coverage. The Speakers I have are JBL EON 612's which weigh 33 pounds each. They have 3 fly points, 2 on top and 1 on the back. My plan was to use chain and quicklinks to suspend these from a batten. The idea was...

As many know, funding coming from a school district is few and far between it seems sometimes often with the arts falling by the wayside (as it is in my school district) We recently did a capital project renovation (which didnt turn out very well) and my thoughts were "if the district isnt...

We are investigating the possibility of creating a small contour curtain for an upcoming show. We are a high school, and have a relatively small budget. Has anybody ever sewn the curtain themselves, installed the rings, and set up a pulley system that is hand-operated?We're thinking there...

Hey!I've been at the same school for about 3 years now, and recently our Vortek Electric Rigging System has been giving us the "Node Faulted" line. I've researched and found an old thread on this site about this problem where that person was directed back to the manufacturer, Vortek. However...

Hi All, Lately my small but growing AV firm has been doing some intro budget galas at some revamped factory event spaces. In almost every case, the client wants some sophisticated short term lighting. These spaces have (12") wood beams and wood 2x12" rafter ceilings. Lately light trees are not...

I will need a quantity of pipe clamps for attaching battens to the grid. Many of these attachments won't be at a right angle, so Cheeseborough clamps would work better. There are a couple instances where I will need to control rotation of the pipe. Would a rotalock clamp be better than a rigid...

I am having 2 small line arrays installed soon. The contractor is concerned about the arrays rotating as the hoists go up. I recall seeing audio riggers tying a line back to the hoist to prevent rotation but since i was not on the audio crew at the time, I don't recall what the actual method...

Decades ago, if I called something a clevis someone would correct me explaining it was a shackle. You can see where this is going. If I called something a shackle, I'd be told I was wrong, it was a clevis. About a week ago I asked CB if we could make this a 'Question Of The Day' as the...

I am trying to gather documentation on the motors which power the acoustic shell in our mainstage. I did a search and the motor has not only been discontinued by the manufacturer, but has no drawings or maintenance documentation. (I can find a spec sheet which gives me the exact information on...

For all the time I've spent on a high wire (30 ft), completely clipped off, this kind of thing still lurks in the back of my mind constantly.http://www.cnn.com/2017/02/08/us/sarasota-circus-high-wire-fall/index.html

Hi I'm technical manager for a production in a small local theatre and we have a shark tooth gauze we intend to have at the front front of the stage fixed to the front of the lighting grid above the stage. We need to use this gauze during the show for projection and effect but for other scenes...

HELLO EVERYONE!! I recently started working at a theater that does not have a fly system but there is plenty of dead hang space, including three traveling curtains. My question is, would it be possible to remove the curtains from their track and attach hanging, hard flats instead? I am trying to...
