Hey there! I am working on the set for a high school production of GREASE and the choreographer is hoping for 10 rolling chairs for Beauty School Dropout. My stage is rather beat up hard wood so I am looking for the best casters for a smooth and quiet ride during the number. Any suggestions...

Hi, My school's auditorium recently underwent a renovation. We have a dead hung schedule 40 1.5" pipe grid, 4' spacing. Grid is about 17' above deck. I want to see if it is possible to safely mount two loudspeakers from one of the battens, ideally the one just upstage of main curtain, keeping...

So I'm putting together plans for the scenery of a show called Constellations, and I really want to use dead hung mirrors all over the space to further cement my interpretation of the multiverse theory, but since the space is used as a classroom during the day, I need to figure out a way to rig...

Hey everyone. This seems like kind of stupid question, and one I should certainly know by now, so I apologize if it is, but I just want to be sure how these things work, with as little assumption as possible. When reading truss loading charts, I assume this is based on hanging a particular...

A speed square is usualy hanging around. I taped a string with a small weight onto the back side with the electric at spike you can stand at the desired focus point, and line up the fixture with the back of the square. make note of the angle fly the electric in to a working hight then...

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...
