On a job where I needed to hang track from an aluminum truss, the head rigger objected to my use of steel hardware, say that the dissimilar metals coming in contact with each other caused a (chemical, Ph balance, out-of phase, something or other) reaction that weakened the aluminum. I responded by asking him "then why are you using steel bolts, washers and nuts to hold the sections of aluminum truss together? Isn't this dissimilar metal voodoo weakening the aluminum there? An since you ALWAYS put these dissimilar metals in contact with each other at exactly the same critical places, isn't this far more serious than my occasional use of steel at randon points on the truss?" (Dead silence occurred as the gears in his head spun and slipped). Finally he responded, "well, I guess it is okay this time." My questions for the group is "What is the truth about dissimilar metals and trusses? Why would someone say that is is NOT okay to use steel hardware on one part of an aluminum truss, but is okay to use it dissimilar metals on another part of the truss?

You could even check with local church organists--they are often well connected. It's not an uncommon show--there may well be someone in the area who could step in, even at the last minute. (If you were in western Mass my husband could do it.) Don't try to go with recordings--that introduces all kinds of other performance problems. How far along is the production--do all the singers know the music? Is there an orchestra, or just piano? Finding a new pianist would be easier than a substitute conductor. As a last resort, ask the concert master (first chair violin) whether he/she would be willing to take over. Good luck.

Hall > 423-773-HALL (4255) > OK. This is a big subject and books have been written about the answer. I ain't gonna do that cause it's Saturday and I got chores to do. The LONG TERM problem. There is an electro-static reaction between aluminum and steel. Especially galvanized steel. There will be corrosion over long periods of time. Like, maybe 30 years. Field conditions, like being on a boat, will have a direct effect on that time frame. This is one of the reasons we no longer use aluminum oval swage fittings (what you guys call Nicopress sleeves) in permanent rigging installations. We always use copper or zinc coated copper. Those of you with aluminum sleeves in you system need not run screaming from the room. The environment in a theatre is not hostile enough to cause a problem for a good many years. If you have to change out a fitting, however, don't use aluminum as the replacement. The SHORT TERM problem Aluminum is a very soft metal. Steel is not. If you are using dissimilar metals in a situation where there will be abrasion, then you have a more immediate problem. If you are wrapping the aluminum truss cord with a steel sling, and there is movement in the sling 9and when isn't there?) then the sling will eventually saw through the truss cord. In the case of using steel bolts in an aluminum truss connection, there isn't enough movement in the bolt plate to worry about. Or, if there is movement, you have other things to worry about.

I was involved with a series of sessions involving the then new NeXT computer (what ever happened to that eh :-) and was likewise involved with many phone calls to brokers and techs at the conference site. When we got there, everything just melted away. I am not positive of course that worries about Canadian power tie ins and such are completely groundless (no pun intended :-), but what I discovered in Calgary was that everybody there was just as interested in everything going smooth as the people who were coming. I'm looking forward to this conference, it will be the first one I've been to in quite awhile, see ya'll there. Oh and while i'm typing....I have been very pleased with the set of 18x18x24 rehearsal blocks i made using solid styrofoam. I used 2" white stuff...the cheapest styro you can get anyway layered up to the correct thickness and then covered in 1/4 luan sides. The luan was cut to exactly match the end dimensions of the styrofoam...giving 1/4 x 1/4 gap at the corners so that the edges wouldn't cut through the gaffers tape that held everything together. The whole block was then covered in muslin. Both the muslin and the luan was scrap btw. This results in a block of good size that is light enough that the students frequently toss them to each other, and when they drop them nothing happens to whatever is underneath. They can be stood upon and stacked and stomped on and kicked and they have held up well for over 4 years now and have yet to even be recovered in muslin. They need for these lightweight blocks was originally driven because they needed to be used on a dance floor and the plywood blocks that we had seemed to be moved primarily by kicking them from one side of the room to the other. I never expected them to be anything more than a disposable solution but we have plans now to expand our collection into something approaching building blocks, pillars lintels and such, that would allow acting classes to actually use them to build small sets.

It's called 'electrochemical corrosion' and presents unexpected hazards. A popular one, in sailing, is to economise by using galvanised shackles with stainless steel rigging. This rots the stainless steel, in a damp environment. What happens is that the two different metals make like a battery and an electrolytic cell. But you do need an electrolyte. In a dry environment, there should be no problems. Maybe he had a leaky roof.

The basic idea is to get intercom, paging and show sound from multiple (2) theatres that share dressing rooms and green room space. Rehearsals in one space overlap performances in the other. We currently have a two channel Clearcom system in each of the theatres. Our proscenium theatre has show sound and paging to the backstage areas (10-15 speakers on a 70V line). Our Black Box theatre also has a 70V amplifier, but currently only has show sound speakers in the light/sound booth, it does not go to the green room/dressing rooms. As I have considered this project I think having show sound from two theatres will be an audible mess causing people to either turn off the speakers, or rip them off the walls if they are not able to turn them down. I have several class rooms of evidence from our current system to support this theory... What I have been asked to do is to run a single channel wall station from each theatre to the green room, mounted side by side. This would provide show sound for each theatre, SM paging, and intercom communication. This solution also offers the value added benefit of letting everyone in the green room listen to one of the channels of headset chatter in a University Theatre environment....I don't think that's a great idea, but it certainly could be done. Some other solutions that have crossed my mind are: *Get two four channel main stations and use a channel for backstage and a channel for FOH thereby minimizing the headset chatter being broadcast *Try to use a two channel wall station, one channel from each theatre with SM paging from -both- theatres overriding the wall station -I spoke with customer service at Clear-com and they didn't think this was very feasible... I like it because it cuts the number of wall stations in half. *Run the 70V line from the Black Box to the dressing rooms and green rooms and use it for SM paging. I'd still need the Com lines for these areas to be able to communicate with the SM... *Tie the two theatres into the same 70V system for paging... not inconceivable, but it's a pretty major change to how the system is run. Turning the amp on and off between two theatres poses some other problems. *Implement the project as originally described, use the entire budget to purchase speaker stations, belt-packs and headsets. After a few shows of having to listen to headset chatter and show sound from two theatres I'll bet the money will be found to get a dedicated channel of intercom to those areas :-) I'm not crazy about this approach, but at least we'd get a bunch of new belt-packs and headsets this way... No matter how I try and slice this I seem to end up with acoustic gibberish and/or a lot of duplicated equipment in the backstage areas. So I ask those of you on the list with multiple theatres and shared backstage areas; How do you deal with this? Are you happy with whatever your solution is? Is there an ideal solution? Of all the things I've considered thus far, the four channel main stations and duplicated speaker stations seem to be the best option, but it's pretty expensive and duplication of speaker stations seems.... inelegant. Searching for elegance, I remain....

Date: Sat, 22 Jan 2005 12:37:21 -0600 I wish the original poster well but I am concerned by what I am believe is misinformation. On issues of regulations, interpretation of the codes and ADA vary a lot from jurisdiction to jurisdiction. For instance, contrary to one post the size of a wheelchair space in assembly seating for ADA is 33" wide by 48" deep. Then there needs to be an accessible route to each wheelchair space which may be no more than an existing aisle or may require changes to the floor. Reseating does not, in my experience, usually trigger that the new layout be brought to the same code standards as for new. Accessibility per ADA, however, is required even if you don't change a thing. Irwin does, indeed, manufacturer a gravity self rising seat. And I only have picked on a few examples. Please, like anything that involves risk, safety, and significant sums of money, if you don't know what you are doing please get good help. The best assurance of good help in this society is being able to know where the responsibility lies and should there be a problem, know who is liable. Saying that a poster on Stagecraft said "do it this way" isn't a very strong defense even to a director of maintenance over simple repair issues. You've got to consider layout, accessibility (ADA), aisle lighting, comfort, appearance, durability, maintenance, replacement parts, perhaps aisle handrails and guards, ushering and house management, clearances for egress, pulling seats for extending the stage, and so on. Having to do it by June is a tough task.

I don't believe there is one right or correct choice for every product as to where a product or system is specified but regarding stage lifts - I never recommend they be specified with elevators, traditionally div 14. A stage lift is not an elevator. It is more often installed by the people doing the rigging than those doing the rest of the elevators in a building. Being in 14 often times brings the issue of elevator codes and inspections which invariably leads to disaster. Pit lifts in Michigan that have to have controls on a stand on the lift so someone in a wheelchair can operate it. Or barriers all around the lift when it moves. Bad stuff. I don't even call it an elevator. As for lighting - lots of strong feelings and regional variations. In Texas, for instance, it seems to be a common practice for Div 11 to supply and install it - complete with their own electricians for all conduit. Strange but true. I like a tight spec and the regular div 16 electrical contractor to shop and install the whole thing. I hate divided responsibility where when something doesn't work, you have a long time pointing fingers and assigning responsibility. Others believe that being in div 11 will bring a theatrical dealer into the project and that there is added value. Some regions "package" things - dimmers, lights, wire, and conduit. This can be bad or good - as long as there are packagers who represent equipment you want. I have often thought that a pre-bidding of the lighting system was best, where approved manufacturers are asked to bid just the theatre lighting equipment package before the electrical contractor bids and then the low acceptable lighting package is assigned to the electrical contractor. Manufacturers bid once, not both before and after the electrical contractor. The electrical contractor knows exactly what he will have to install and how much it will cost him. Unfortunately, that approach isn't often allowed.

Here is one place where I will say you have got it wrong, and that the UK custom is better. Our G-clamps do not need a wrench to tighten them, just a thumb and two fingers. Short of repealing the law of gravity, even untightened they will hold a lantern up. Yes, I know that the law of gravity is sometimes upset by the movement of flown pieces. Tightened, they will hold a lantern standing up from a pipe. They are also made of mild steel bar, rather than iron castings, and so not suceptible to fracture by overtightening. The aim of the lanterns is determined, in azimuth, by tightening a wing nut, again with your fingers and thumb. Since all the bolts are 3/8" or 8mm, the prospect of breaking anything is low. Occasionally, you do find lamterns with hex nuts in this role, but you do need to be a real gorilla to do them any harm with a 6" crescent wrench.

First: Electrolysis requires an electrolyte. In a dry environment, there is nothing to carry the galvanic currents. Adding an insulator like a wrap of tar paper or plastic between the metals will stop the process cold. I have never seen a compelling explanation of why steel and copper, which are also dissimilar metals, are considered good, while steel and aluminum are considered bad.

I don't think it's that they're considered good, just less bad? Different metals have different electric potentials relative to each other. Somebody that knows much more about physics can probably explain why. Copper and steel have less potential (voltage, I believe) than, for example, steel to aluminum or aluminum to copper.

Subject: Re: Dissimilar metals Date: Sat, 22 Jan 2005 22:38:53 -0500 there is a chart the exists somewhere that has most metals listed on it. The further away the metals are on the chart the worse off they are together, and the closer they are the better. I don't have copy of it with me so i can't really go into more detail. Has anyone else ever seen anything like what i'm talking about? Some one mentioned earlier that the dissimiliar metals will basically create a battery and that's exactly how i've heard it explained to me in the past. The phrase galvanic corrosion also comes to mind. You boat owners out there may realize that this is why there most likely is (or should be) a piece of zince bolted to your boat somewhere below the waterline. The way i understand it, the zinc acts sort of like a lighting rod and will be the piece to corrode and should be replaced every so often. Not sure that i have a real point here, just trying to share my experience and hopefullyl provide a bit more understandingof the process. I also don't think that aside from the previously mentioned examples that this is a large problem in theatre or that it was in the original post.

Subject: Scholarships? Date: Sat, 22 Jan 2005 23:31:42 -0600 I am a high school senior and am appling for scholarships. Instead of writing long winded eassys about concrete or how my degree in technical theater will save monkeys I was woundering if there are any scholarships directed towards techs. I do not have any pictures of designs or interesting things I have built I do have a few killer letters of recommendation from the executive director of a nonprofit theater group and from my drama instructor.

It will feature product reviews of tools and gadgets that I come across in my work out on tour, stories of funny/weird/frustrating/interesting happenings from on tour, tips and tricks from my own experience and that of the other technicians I work with and meet, and occasionally random other things like book and movie reviews, restaurant reviews from the road, and the occasional recipe (right now there's a recipe for some incredible near-instant hot cocoa that I posted a few weeks ago, for example!). Check it out, and let me know what you think! Also, if any of the artistic sorts out there want to try their hand at a logo design, I'm up for suggestions. I might even find something appropriate to give away as a prize for an official OFTR logo contest, we'll see... So, hop on by, tell your friends, and if you're of the geekish persuasion, go ahead and subscribe to the RSS feed (try http://www.bloglines.com for a free RSS update notification service that a web designer friend of mine pointed me to).
