Our stations each have shut-off valve -> drain plug -> Filter -> Regulator -> quick-connect -> Oiler -> Manifold w/ 2-4 connections. The one quick-connect before the oiler is for tools that shouldn't be oiled (upholstery staplers) or blow-offs. Works pretty well for us.

Your story does bring to mind something I've noticed over the years, though...strikes and load-outs tend to be more dangerous than other situations, partly because of the inevitable chaos, partly because of the nature of planning an install/load-in, and partly because those things tend to happen at the end of a long day/week/month when everyone's mental fortitude isn't what it was at the beginning of the process. Practically ALL the injuries I've sustained over the past few years have been in just these situations, from a herniated L5 disc (trying to move too much at once) to the four stitches I got under my left eye when a flat collapsed (bracing was removed before it was lowered to the ground instead of the other way 'round). On a bus-n-truck a number of years ago, we were loading out of a school chapel down a hill at night (no loading dock) when one of my singers slipped on the damp grass carring a flat backwards; she broke her wrist in the fall. As painful as it is, your reminder hasn't gone unnoticed, and I'll be modifying some of my lectures this semester to drive home just this sort of thing... ------------------------------ Subject: RE: Theatre Engineering and Architecture Conference Date: Thu, 22 Jun 2006 09:20:17 -0400 Message-ID: <6E497ADB607656479C24E6D7BF6B505A042A9CBC [at] exchange.rmwc.edu> In-Reply-To: From: "Paul Schreiner" > << Adobe and staw bales?

Jon, as I have no knowledge of your situation, save for what you have shared with this group, take my thoughts with a grain of salt. It sounds like the administration controls the school board rather than the other way around, and they have little respect for you and your department. This puts you in a bad position. Your comment that they see you as a "noisy troublemaker" would indicate to me that you need to re-evaluate and modify your approach in dealing with them. Are you constantly complaining about problems? You may well have reason to, but at this point it's counter - productive. The more you complain, the more they will ignore you as a malcontent. The squeaky wheel doesn't always get the grease - sometimes the squeaky wheel is the first to be replaced! ;-) Try not complaining whenever something is wrong, but instead: "Choose your battles" and quietly gather statistics, facts and figures so you can make a cool headed presentation as to exactly *why* a specific issue should be handled differently. Write up a fact backed report that focuses on safety and/or financial reasons that your proposal should be implemented. If the administration ignores your report, "Leak" it to the school board and the movers & shakers. If it's well written (Plain English) and makes a compelling case, it will have more impact than "Constantly complaining". Also, What is the image of your drama department in the community? If you are known for producing great shows that the taxpayers enjoy, you can elevate your own profile. This would give you a stronger position in dealing with your nemesis - the administration. Again, this is one outsider's opinion - take it for what it's worth. Good luck in any event!

I don't know about that - municipal water supplies tend to be around 30 PSI or so, whereas your tools will want your air pressure up around 125 PSI. Maybe it's a personal prejudice, but I've never been comfortable using compression fittings - I much prefer sweat joints.

Not my area of expertise either, but I can assure you that *Someone* is out a lot of money! If it was insured, and if the insurance covers it, then the insurance company is out a lot of money. Of course, their executives and stockholders won't lose any money - all those premiums that everyone pays are affected every time the insurance companies pay out! Bottom line is, although it may be divided up amongst a lot of premium payers, someone is going to have to pay for it!

True, and using a 3" piece of tubing, and then a 2 1/2" on top of that, and a 2" piece on top of that (building up a taper) with all of the ends nearest the connector being flush, will mkae it even better.

He told me that the recently accepted standard for attaching trim chains to lift lines is to shackle back to the chain rather than to the thimble eye. The reason he gave was that it created a more direct line of force off the thimble rather than the two slightly offset forces of the chain and shackle. I was taught, and according to my references, to terminate the cable with one end of the chain in the thimble and to shackle the other end back to the thimble after a wrap and a half around the pipe. Now I admit that I am not in regular contact with installation contractors, but I was taught this method as recently as February at a rigging seminar. What have others heard recently? Did I miss a change in recommended practice?

The definition of "overhead Lifting" in regards to chain from every chain manufacturer and rigging manufacturer that I have dealt with means that it is actively involved in lifting the load. A trim chain is a static load, not like a Chain motor which is overhead lifting. Even with a proof coil chain, several other parts in the system will fail before a trim chain does.

Jeff, While I will agree with you that the term "overhead lifting" generally refers to the use of a chain hoist, I disagree with you that the load is "static."

You paint the floor in one color of brown, let that dry, then paint on a darker brown and drag the tool through the wet paint. A little rocking motion creates the variations in grain. Look for it in the faux paint tools section. This was for a floor in a small theatre where the audience was very close. It looked so realistic, I had people coming up after the show and reaching down to feel the floor to check if it was real wood.

I don't believe the rep is wrong. He/she simply has a different opinion. Let's take a look at 1/4" proof coil chain. It has an identified Working Load Limit (WLL) of 1,200 pounds. (+/- a little bit depending on the manufacturer). Does that make it the weak link (sorry) in the system? No. The WLL of 1/4" galvanized aircraft cable is 1,000 pounds. Assuming you are using wire rope clips to terminate the wire rope, then the WLL is reduced to 800 pounds. If you are using swage fittings then the WLL of the cable is 950 pounds. So, does that make the cable the weak link? No again. Check out what the rigging equipment manufacturer rates their loft blocks for and you will discover that the loft block is usually the weak link. Bottom line....it doesn't matter how you terminate the trim chain, it will still have a load rating far and above the other components in the system. I do not care how you connect the trim chain as long as the method used maintains its' load rating. I do know that if you put the shackle back into the thimbled eye then trimming the batten becomes a bit more difficult. Bill S.

Unless, of course, you have a couple of the guys from the football team jumping off the locking rail to get the lines started. A better example of a shock load is when you turn on or off an AC motor, as in a chain hoist. Not only is that shock load measurable, it's visible. Bill S.

If it was insured, and if the insurance covers it, > then the insurance company is out a lot of money. According to the news story, the screen is operated by the city. If that is the case, they probably do not have property damage insurance - just liability. The monetary loss is likely to be far less than it could have been. Apparently the LED cubes were not damaged. No idea how much it will cost to replace the scaffolding.

I had many an opportunity to work with Alan and sadly I hadn't seen him in a few years. He was a quiet genius. On occasion he would contribute here on stagecraft. I believe it was Alan who started the thread about how to implode a house with only atomized household flour and a match. A man of many talents he was invaluable at Harvard and every student of his that I have worked with was well trained and eager to learn. I used to use his kids as spot ops on a skating show each year at Harvard. I met Alan while doing an opera in a dining hall there. I was the newly minted LD who wanted to rig a pipe 40' in the air around 2 antique chandeliers for the Magic Flute. The house Facility guy called in Alan and after a lengthy quiz about what I intended to do Alan allowed me to proceed. I met my wife on that show. Michael can correct me if I'm wrong but I believe Alan held part of the patent on DMX-512. He was able to talk and teach about any kind of theater control and once loaned me an NSI Melange' console because it was the only console at the time that would take random access MIDI go commands and the Media Lab wanted to run it off a Mac. (in 1994). We spent about 3 days troubleshooting that beast and it finally did exactly what we wanted it to. I believe Alan designed and installed the lights in the penguin exhibit at the Boston Aquarium. His stories of swimming with penguins and electricity were a joy to hear. A google search sadly does not tell the full tale of his accomplishments or his personality. But 2 hits are interesting. This article from the Harvard Crimson Supporting Alan when his job was in danger, defines his day to day dedication to theater at Harvard. Happily his job became permanent and the clutches of the ART on the Loeb were loosened slightly. http://www.thecrimson.com/article.aspx?ref=218546 This article is about one of his students but Alan is quoted frequently. http://www.harvardmagazine.com/on-line/070401.html I tried to search our stagecraft archives but they seem to be buggy. Alan was a charming genius and indeed he will be missed by many.

Interestingly, and coincidentally, I was just reading about Alan just yesterday (Wednesday) - before the knowledge of his (much too early) passing -- and thinking what an amazing man he was. Let's hope Harvard can honor Alan in continued work towards his passions and dedication - not just toward his students, but towards the industry as a whole. - Jon Ares www.hevanet.com/acreative ------------------------------ Message-ID: <1346.205.215.255.111.1151045705.squirrel [at] webmail.peak.org> In-Reply-To: References:

Not necessarily a comparable situation, the HVAC lines are relatively small in diameter. Remember that, for any given schedule of tubing, the pressure rating drops as the diameter is increased. But as long as the copper is rated for the pressure, and well protected from damage, it should be fine.
