Or maybe buy them on the cheep? How large are you thinking? What about large-diameter PVC and a couple of heat guns (and a bunch of time)? Construct a curved jig to bend the PVC against as you heat it a little at a time... If you can find a diameter of ethafoam that works for you (I've seen it up to 6", but it may come wider than that...), another idea that comes to mind is slicing it in half lengthwise and then gluing it around some conduit. Bend the conduit (dunno if I'd do it before or after application of the foam...have to ponder that) into a candy-cane shape and you theoretically might be good to go. I could probably come up with some other possibilities, but these are the first two. Don't know if the ethafoam idea is practical though...my experiences with ethafoam haven't been very pretty, so I'd lean towards the PVC instead. Oooh! I know! Find an old inner tube with almost the same diameter as the sonotube, and make a plaster mold of it! Cut the mold in half for the curves of two candy canes and attach those to the sonotube uprights! Okay, now I'm getting carried away... ------------------------------ Message-ID: <147CF8DFB9C5D41187300001FA7EE390213D7020 [at] mail.nwmissouri.edu> From: "Immel,Patrick" Subject: RE: candy cane Date: Mon, 27 Sep 2004 12:58:36 -0500 Roger, I have made CC's in the past using good carpet tubes.

Or you can pack the tube PVC with sand to keep the walls from flattening as you bend it. If you can enclose the PVC in a larger metal vessel to hold the heat, it will heat more evenly and bend more smoothly. Good Luck.

We're trying to determine if the work crew/project crew broke safe working rules/standard operation rules by not x-raying first. IN the US there is no rule or common practice to xray or ultrasound a wall before drilling. It is common practice to review any reasonably available blueprints. Did those conduits appear on the blueprints? Did the project supervisor check those blueprints? This sort of thing should be repaired at the contractor's cost, unless the contractor was specifically told to "Drill here." then that responsibility transfers to the person directing the drilling contractor to make the hole there. I'm surprised that the contractor just didn't call in an electrician to repair the broken lines. This sort of thing does happen to them fairly often, so they ought to have a procedure to make repairs. --Dale ------------------------------ In-Reply-To: References:

Unlike drilling through an ordinary line, that would be hot all the time, A dimmer circuit might not be noticed for weeks, or months. Imagine if the guy drilling would say to his boss "Hey Bob, look at this core here, I think I drilled into some wires" I would more imagine that he would just throw away or hide the core with the offending conduit & wires. ------------------------------ From: FrankWood95 [at] aol.com Message-ID: <13d.2a4f15b.2e89e66f [at] aol.com> Date: Mon, 27 Sep 2004 17:55:59 EDT Subject: Re: 11th use of a stageweight?

As a resident of the UK, where pistol ownership is uncommon, and has recently become totally illegal, I am less familair with their usage than you. Nevertheless, as with any firearm, I think that there needs to be a stationary period, to take aim, if you want realism. And, just what this has to do with the SM I don't know, even in your scenario.

All of them show a pretty unbelievable numbers on the lamp hour counter, leading me to believe that the counters were not reset at some point. The lamps are Phillips MSR 575s. According to Phillips, exceeding 1000 hours on the lamp increases the risk of catastrophic failure (boom!). Is there any way I can estimate lamp life based on the condition of the lamp, or is my only safe recourse to replace all the lamps? And on a related topic, is there any reason not to replace the XLR-3 connectors on the MLs with XLR-5s? It's a cheaper solution that building adapters or buying new cable, but there has to be some reason the rental house I bought these from didn't make that change. Thanks! Steve L. -- Stephen C.

How dim the output is. If the output is thoroughly pathetic they need replacing. 2. How green the light output is as MSR 575's tend to turn green at the end of their life cycle. 3. How much vitrification is on the lamp envelope. Or how white has the lamp envelope turned. If it is very white or has big white patches, the lamp needs replacing. If it is still clear to cloudy and still has good output you are probably OK. I know these factors are very subjective but after you do a lot of work with moving lights you recognize the first two items and the third just confirms the first two as you change the lamp. Also many rental companies do not go by lamp hours because strikes also play a part in lamp life. The more strikes the faster the lamp ages. Since they don't pay attention to the lamp timer they never bother resetting them. A good tech that knows the lights will keep them looking good and maximize lamp life or replace it early regardless of what the hour meter says. As far as the 3pin XLR's you never mentioned which fixtures you own. Some of the High End fixtures have the XLR's soldered directly to the PC board while others have a wire harness. Fixtures with a wire harness are easy to change while the direct to PC board are more difficult. Most rental houses don't change the connectors so there is no question as to the configuration of the gear when they rent it. The person getting the gear knows what connector they are getting. If you keep it original equipment there is no question about it. There is nothing more annoying than renting a piece of gear and finding you don't have the correct cables because the rental house changed the connectors but didn't bother to tell you. Of course shame on the manufactures for not following the DMX 5 Pin XLR standard from the beginning. :-) I hope this helps.

They just have to have 3 pin cables in their rental inventory or make sure the renter knows the connector supplied. I never figured out why many of the ML manufacturers put 3 pin on their instruments (cost?). At least some of the console manufacturers are putting out consoles with 3 pin connectors. By the time you have torn the fixture apart and successfully swapped out the 3pins for 5. You may as well have either made all new cables or swapped connectors on existing dmx cables. Then just make one 5 to 3 pin adaptor for the console to the first fixture in line. Good luck.

I replace the 3 pins with 5 pins wherever possible in my own gear. That way almost all of my leads are 5 pin and I only need the odd adapter for the ones I couldn't change. (PCB mounted too hard) Consoles with 3 pin connectors are just as bad as 3 pin fixtures! The DJ market has a lot to answer for.

Well, all 32 DMX outputs onstage are 5-pin connectors. Every DMX device I have so far (foggers, rotators, etc) have 5-pin connectors. I can either stock two kinds of cable and have well-meaning students confuse sound and DMX cable, I can build adaptors for each 3 pin light (at $15 ea parts) or I can change out the connectors on the light for about $10 ea. We have Martin 500s and 600s. The connectors look to be a pretty easy swap and it's chance for my lighting tech students to go inside the light and see what makes it tick.

Everyone grab a partner and start dismantling. In response to another email mentioning DJ equip. I know High End and Martin both used to supply 3pin as standard. I wouldn't consider them DJ lights (or at least their top models.) What are the other models supplying as standard?

The DJ type equipment was the first to start using 3 pin in a big way IIRC and then the larger manufacturers started too. I'd rather just have everything 5 pin. One type of connector, no adapters to mess with and less connections to go bad. Just be thankful they haven't moved to 6.5mm jacks for the DMX like some of the early stuff had for communications!
