Certification only means that the individual has "met the specific eligibility requirements including training, experience and education, and passed a rigorous comprehensive examination." From what I have read and heard about the throughness of the exam, it is MY OPINION that anyone who can pass the theatre rigging exam should be capable of inspecting a mechnical counterweight system. This is what I stated in my last post. I am basing my opinion on my review of the "Examination Content Outline - Theatre Entertainment Rigger" on pages 18-20 of the ETCP Candidate Handbook. While this outline does not specifically say that the candate should be able to inspect a mechnanical counterweight system, it does say in Section 3.A.1. STANDARD SYSTEMS (referring to: counterweight, hemp, powered and powered assist, curtain and track, fire curtain and smoke vents") that candidates must be able to: a. Identify components of specific systems b. Understand design properties=20 c. Install and operate spotlines set(s) d. Determine appropriate anchoring locations e. Bring load to a controlled stop I take this to mean that the candidade must have a complete knowledge of these systems and therefore, in my opinion, have the knowledge to inspect them. Furthermore, Section 3.A.6.f. (referring to Curtain/Track) and=20 Section 3.A.7.a (referring to Fire curtain/Smoke vents) does specifically say the that the candidate must be able to "Inspect system." I also believe that parts of Sections 1.B.2, 1B.5, and 1.B.7 also relate to a complete understanding of the design principles of a mechanhical counterweight system. I maintain my belief that a person can pass this exam, should should have the knowledge to inspect a counterweight system. Since you seem to disagree with this statement, I think a lot of people on this list would like to know why you feel that I person who passes this exam would NOT have the knowledge to inspect a mechanical counterweight system.

I'm not saying I couldn't have handled it better...there were a lot of issues w/r/t that particular production. The tone of my response was actually a lot nicer than what it translates as over email. The approach she took was adversarial from the beginning, assuming that I was just letting it slide, when in fact had she asked why there wasn't a railing yet we could have cleared the whole thing up. The attitude of second-class citizenship, however, colored her whole approach...and my response. It's always a two-way street, and after 3 1/2 years of putting up with it at that point it had begun to wear on me. It also didn't help that she was either engaged to or married to a gentleman who was a TD at another theatre. =20 > Bitch or not, she's still the director.

Again, under that type of rather poisonous atmosphere between faculty and staff (and while I'm at it, let me also indicate that the design faculty did not have the same approach--it was entirely the acting/directing faculty who took that attitude), bringing things up like that only serves to get that on public record. It doesn't actually mean it's going to happen that way.

Another popular material (I think already mentioned my others) is Ultra-High Molecular Weight High Density Polyethylene (variously know as UHMW or HDPE or some combination there of). The Delrin may be a bit more wear resistant (higher value for allowable compressive stress) than HDPE. HDPE has a lower coefficient of friction. I'm including a couple of links from a site called MatWeb ( www.Matweb.com ) The first is for one of many available Delrin products, the other for an overview of HDPE.

For some, once a month might not be often enough. Others, with a trained, vigilant staff, an outside contractor for inspection once a year might be overkill - though ironically they probably are the theatres that do have regular inspections. All this overlooks what an inspection entails or what qualifications an inspector should have. I've seen too many "inspection reports" that clearly are walk throughs or the same canned warnings and admonitions and don't demonstrate much knowledge and understanding of a particular facility. I don't do rigging system safety inspections. Were I responsible - read that as liable - for pronouncing a rigging system safe, there would be a lot of closed theatres. One starts asking questions like what's the origin of that cast iron sheave or that wire rope, or what's the building structural framing designed for, and it gets real time consuming real fast. It requires someone that does it everyday. (For similar reasons I wish rigging manufacturers and contractors wouldn't do consulting but some will fail to see the logic in that.) Frankly, I don't know how someone not intimately familiar with the original installation can do an inspection. But I guess some folk believe that an independent mechanic is always better and more objective than the factory trained mechanic for that particular make and model. I wondered if the objection to this was more a case of the same individual rather than the same company. I'd generally recommend the same company, if reputable, but would assume their own q.c. would have individuals other than the original supervisor or foreman or installer conduct subsequent inspections. So of those of you who do offer inspection services, how many of you take full responsibility for the system when you are done and your recommendations followed and don't disclaim any responsibility for the safety of the system?

Thanks Peter. Like many others, I am still trying to figure out the ETCP. The ETCP Handbook that says that "ETCP certification ... provides public validation and public recognition of your skills,"=20 but it does not seem to make reference (at least none that I could fine) to specific skills that a ETCP Certified Rigger can claim to have. In spite of the quote in the handbook, it seems to me that ETCP certification does not certify a technician to have any specific skills (qualifications to do any specific job). It seems to me that be an ETCP Certified Technician is one thing, and claiming to be "qualified" to do a specific job is another. Do you agree or disagree? If you disagree, can you tell us what skills an ETCP Certified Technician can claim to have? This seems to be a VERY important question because the ETCP Code of Ethics and Professional Conduct states that an ETCP Certified Technician must "avoid actions which falsely or misrepresent one's professional qualifications... " The handbook states that, "Certifications indicates a substantial professional commitment to the field and documents this expertise to employers, colleagues and professional organizations." Is this a "skill?" I don't think so. I just have not seem any specific skills a ETCP Certified Technician can claim to have, and I suspect we may never see any. Again, if I have missed this information, please point me to it. Finally, what knowledge/skills do you feel that one must possess in order to claim to be a "qualified" (not certified) inspector of mechanical counterweight systems? And, is this knowledge not covered on the ETCP exam? It seems to me that it is (or should be), but I would like to hear your opinion. Again, let me say that I am talking about being "qualified" (having the knowledge/skills) to do this job, and not be being "certified" (have these specific skills recognized by an independent organization). The ETCP is very new and there is a great deal that I do not know about it. Thanks for answering my questions and setting me straight on my misperceptions.

I'm going to have to back up Paul, here. As the TD it's his job to install the railing, not design it. If the designer really doesn't want a railing there, that's a discussion they should have and resolve it without putting the TD in the middle. Perhaps he could have handled it better (I don't know, I wasn't there) but the director needs to communicate her needs through the scenic designer. Unless it's a railing on an escape platform in which case just put the railing on. Steve L. -- Stephen C.

You can have quality at low cost... But it won't be fast. You can also have quality quickly... But it won't be cheap. You can have fast and cheap -- no problem!! -- but it will not be good. For custom stuff, with the appropriate team working on it, you CAN have any two -- even the worst two. For manufactured stuff you sometimes seem to get all three, but only because production started before you asked. The people behind the scenes at the factory face the same dilemma of cheap/fast/good (What price do we need to come in at? How long can we wait to get the first pieces on sale?). Beware of a low-cost product that didn't exist at all last month -- it's likely to be "good and cheap" in a bad way.

It isn't _supposed_ to be! The NEC already covers this question by requiring a grounding wire, (a.k.a. the "green wire" in US practice) to be included in the circuit cables. This is true for single circuit cables, multi-cables, flexible conduit, and even rigid metallic conduit (although that can also use the metal conduit itself as the ground conductor). The point is, the path to ground or earth should be supplied by the electrical system, not by the rigging system components. In fact, the NEC doesn't want alternate paths to ground, with a few exceptions for farms and such. That doesn't mean a batten won't be grounded, but instead of being done through the rigging cables (insulated as they are by delrin sheaves), it happens through the lighting instruments. As in: Green grounding wire from cable is bonded to instrument body internally. Yoke is attached to grounded body, C-clamp is attached to yoke. C-clamp bolt bites through paint on batten, bonding the batten at each instrument. This way, electrical grounding of the rigging system is the job of the electrical system, which should be designed to do that job, instead of depending on the rigging itself, which should concentrate on keeping everything from crashing to the floor!

Including the building steel frame and so on. Constructing a building that is actually not connected to ground is rather a challenge, and only done for things like NMRI centers and other specialized construction. Having all the metal in the building connected to the building ground system gives the electrical safety system another chance to correct the fault. Say the ground wire for the only instrument on the batten is open for some reason. faulty cable, bad screw, corrosion, error, whatever. If the pipe is not connected to the building ground system by another path, when the instrument faults and energizes the pipe, the next person who touches it when the light is energized, say the electrician who is up there on the lift to replace what he thought was a blown bulb, gets lit up instead when the ground path completes through them and the genie lift. I like systems that require more than one failure to produce a dangerous situation. > > That doesn't mean a batten won't be grounded, but instead of being done > through the rigging cables (insulated as they are by delrin sheaves), > it happens through the lighting instruments.

Agreed, to a point. But going to the extra effort to electrically insulate the rigging seems pointless to me. It removes a safety ground path, and the insulation on the weight bearing parts would wear through fairly quickly, I would think. I'm not going to count on the rigging system to be grounded. But if some yutz back at the shop miswired a lot of cables, cutting off the ground wire, "Because it wasn't needed and was too much trouble to crimp on.", I am going to really appreciate having that alternate path to ground. Part of safety planning is knowing how things go when something fails. If the system fails in a safe manner after [any given fault], then you have a much safer system. --Dale ------------------------------ Date: Wed, 13 Apr 2005 13:42:14 -0400 Subject: Re: New here From: "C.

Well, Dale, if you and your crew would just look at my carefully crafted groundplan and READ THE NOTES, you'll see I've considered those issues, such that all parties involved have equipment areas outlined and all fire code and kitchen access is kept intact. :) I keed, I keed...

I saw a performance at ACTF over a decade ago that University of Kansas, Kansas City, created. It was a production of The Adding Machine and used a) virtual sets, b) 3D projection technologies (with the polarizing glasses and everything) and c) a virtual character controlled from backstage by an actor wearing a motion-capture suit. Space age stuff then and... Apparently, still is. Haven't seen the like of it since, though I've seen some good attempts. And this was for significantly less than $1.8 million. Also, in more recent times, I had the priviledge of seeing a dance piece that utilized the performers' interruption of lasers to trigger music samples, in such ways that one or two of the lasers, if activated by itself, was like the other music samples, but if activated in concert with other activations, would be like a shift or control key and the whole soundscape sampled from a different set. Amazing beautiful movement and somewhat creepy audioscape.

I feel that the TD is also the "safety officer" and if the railings were needed for safety purposes, this should have brought up during a production meeting. The set designer would then be put on notice that he needed to design the railings and the deadline for submitting the design to the shop. A related story: When I was a grad. student, I was the stagemanager for a production of Hamlet. The set had a raked stage that became very slick during tech rehearsals and the actors were falling because of this problem (especially during the fight scenes). The faculty set designer was out-of-town and could not be reached, so the faculty director begged me to fix the problem. I discussed the problem with the student TD and we came up with the idea to use strips of non-skid tape across the stage. The ran the idea past the director and showed him the pattern for the strips that we planned to use. He OKed our plan. We added the tape and this solved the sliding/falling problem. The director and the actors were happy. But when the set designer returned and saw our "solution" he was very upset agruing that we had changed his design by adding the strips of tape (yes, they were visible athough we did out best to diminish their visibility) and should not have done so without his approval. I understood his point and actually agreed with it, but I felt that the safety of the performers over-rode the artistic issue (especially at the insistance of the director). I agree with Steve here, in Paul's case, I feel that as long as the set designer as available to design the railings, the note should have gone to the designer, not the TD. Once the TD got the design it would then be the TD's job to make sure that the railings protect the actors from falling.

In the case of a batten that does not have permanent distribution attached to it you are at the mercy of the ground wire in the fixture and cabling you are using to power the fixture. This is NEC's solution to the problem as Mick pointed out. Although I agree with Dale that there can be a ground path through the rigging steel, this is not always guaranteed with the use of Nylatron sheaves in the rigging system. Also this ground path, if present, may not be as low a resistance as the ground through the Genie lift causing you to get shocked anyway. As a lighting guy dealing with power all of the time, I developed a habit of making my first touch of an unknown, possibly energized, object with the back of my hand before I grab it. This habit developed out of working with a lot of generators (but that's another story) and has saved me from possible severe shocks. This is a good first defense that you have total control of. The other best defense is to keep your lighting gear and cable in good working condition. Beyond that if you are really worried about it you could add a ground wire to your batten that is bonded to the building or an electrical ground. Nothing is 100% guaranteed to keep you safe. If there is a failure of one or multiple systems then the situation becomes unsafe, of course this is generally what happens in a failure situation.

Being qualified to do a specific task (or job) doesn't necessarily require a "certification" in a certain "Body of Knowledge" (unless required by law, such a medical certification).

He/she (let's not forget all those other folk) cannot claim that they are certified "to do" anything. What they can claim is that they are certified in "having demonstrated proficiency in knowledge as tested by the ETCP" (my words, my quotes, not anyone else's).

There's a ground plan? and NOTES? Wow. That's good. Much of the time what we have to work with is a floor diagram that we swiped from the hotel housemen who are setting up the tables and chairs. While these ground plans do eventually show up, they are often too late to do anything about it, as the rig is in the air and the wait staff are setting the tables. When the plan is there on time, and we set things up correctly, the client inevitably comes in and wants some major realignment of the room. The truck driver usually doesn't have anything but a bill of lading. The housemen are working off the rough sketch diagram from the original hotel contract, and the person with the information is still at the airport and is expected in two hours. The hotel has to have all the gear in place in four hours so they can set the tables and chairs. Been stuck in that place too many times. --Dale, who is feeling a bit snarky today. ------------------------------ Message-Id: In-Reply-To: References: Date: Wed, 13 Apr 2005 14:30:11 -0500 From: "richard j. archer" Subject: Vacu form machine Group; I know we've probably been down this street but does anyone know of a firm that sells a vacu form machine for under $5K or so?

Once upon a time, for a few years long ago, when I was far less well traveled & less jaded and I had a waist - I was the SM & PSM for the Twyla Tharp Dance Co. Oh those # [at] $%**&## scuff marks, Jackson Pollack, right on Keith, perfect image. Twyla's choreography leaves a distinctive kind of curly, toe twisted shoe mark that I have really never seen from another dance company. I used to be able to tell from the scuffmarks on a floor as it was unrolled (most of the time we used local floors, and did not carry our own) if the company had previously danced on that particular floor. We dealt with the scuffmarks as follows- A bit of elbow grease and a rag with denatured alcohol solvent, followed immediately by a rag soaked in water, immediately drying the area with another clean rag. This worked on 90% of the marks. For the really stubborn marks we borrowed shoe dye remover from the wardrobe dept. and used it extremely sparingly and quickly, repeating the process above. Twyla's company also could not dance with gaffers tape on the top of the dance floor - the same toe twisty choreography that leaves the scuffmarks makes gaff tape a trip hazard for the dancers. We developed a great method of laying dance floors with double-faced gaff tape from below, easy, quick, great looking and safe- But that's another post! Sorry to digress into my far distant past. (Putting on my current hat) MOVIN' OUT's floor: A) It is a Harlequin surface, on the road it is laid on a sprung touring dance floor, in NYC, I believe it is on top of a speed deck, also with a sprung floor B) Cleaning - Daily they use mop and water with a tiny bit of Slipnomor in it, and I believe they spot clean marks, unclear about what they use to do the spot cleaning. As you stated the Orchestra seats can't see much of this at all, I bet you saw it after the following step -Every couple of weeks they buff the hell out of it with a nylon scrubbee type pad and then immediately apply a Slipnomor & water mixture as the buffing process can make it extremely slippery. ATTENTION, EVERYONE OUT THERE ON THE LIST WITH LIMITED BUDGETARY RESOURCES: MOVIN' OUT is a Broadway show. If the Buffing process is damaging the floor and the show needs to purchase new one a couple of times a year, because the cleaning process needed to keep the show looking fresh is destroying the floor, it is not the end of the world for them. This procedure used over the long run may be harmful to a dance floor, the only dance floor you will have until someone coughs up the bucks for a new one. Be cautious - do not try this at home - or if you must, at least test it on an offstage portion of one panel of flooring, or better yet on an old rehearsal floor. YMMV. End of Disclaimer.

In the UK, it is usual for the batten to be grounded other than through the luminaires hung from it. Certainly one must never rely on the suspension wires. If, by mischance, the luminaires fail to provide an adequate ground current path, and the fault current tries to make its way to ground through the suspension , there can be big problems. Steel wire is not a terribly good conductor, having about 40 times the resistance of copper, and fault currents may be large. Enough to heat the suspension wires to red heat, at which temperature they have lost a lot of their sterngth. I have heard of this happening, although I have not seen it. Apart from the electrical hazard, you may have the whole thing fall. OK, it's a remote chance. I think that there must have been serious breaches of the electrical codes, but such things can happen.

You need to make sure that those who need to know know what they need to know. I'll give you an instance. Many years ago, I lit Arthur Miller's "The Crucible". As we work normally on an arena stage, we use little scenery, and rely on the lighting design to create the spaces. We also have a very leisurely schedule, getting in on Sunday afternoon, and running the tech the following Saturday. The day before the tech, the director says to me, "By the way, the Act I window isn't thee, and the Act II window isn't there, nor is that in Act III." This involved a lot of re-rigging. I thought that I was very moderate when I asked her, "Why did you not tell me sooner?", albeit in a pointed fashion.I got some garbled reply about a message which had gone astray, which I did not believe. At the production conference, and at any preliminary meetings, I think that the director ought to have the show defined. They may change their minds, and I don't really mind that, IF they tell me what they have changed them to. Beink kept in the dark is frustrating, and non-productive.

I had assumed that all parts of the energy spectrum from DC to Light (and beyond) should behave like EMR in the audible range under the same highly controlled 'vacuum/anechoic/non-EMR reflective' test conditions that are free of any particulate matter in the beam path that could refract the beam. I assumed wrong, I guess, as they immediately steered our conversation back to showing me their mathematical 'proofs' that disprove String Theory. Since arrays of monochromatic LEDs are being used as stage light sources, I thought there were some possibilities worth exploring, but, alas, perhaps not. /s/ Richard ------------------------------ Message-ID: <003101c540a2$1656bcf0$0600000a [at] BRUTUS> From: "Jon Ares" References: Subject: Re: baaack & related question Date: Wed, 13 Apr 2005 20:28:55 -0700 >>I usually try to use LumenAbsorb (tm), although if that's not available at >>the local Lowe's, I'll settle for LightAway (tm). > > Does that come in a spray can for localized blackouts?

Also it supposedly will only run on Emphasis using the De-Emphasis software plug in for the system. Although a fixture of this type seems like it would be positive it seems to have a lot of negatives.

Aren't they working on a series of European-only models? The first one out in Q3 is the French Revolution, I believe. More to follow. (I'm eagerly awaiting the new ETC fixture the Inquisition. Spanish Inquisition last. Because, as we all know, no one ever expects the Inquisition.

The problem is the light waves (when it acts like a wave) aren't all in phase. It's like trying to cancel white noise with "anti-white-noise". In theory you could do it, but it would mean you'd have to figure out the phase of every wave. ---------- Jerry Durand Durand Interstellar, Inc. 219 Oak Wood Way Los Gatos, California 95032-2523 USA tel: +1 408 356-3886 fax: +1 408 356-4659 web: www.interstellar.com ------------------------------ End of Stagecraft Digest #362 *****************************
