Penguin_Maz Posted June 28, 2005 Posted June 28, 2005 oh my goodness, I cant believe I am asking this! I'm going to delete as soon as I get the answer! When you rig a lantern, do you hook it, tighten the colt, and THEN attatch the saftey chain/wire OR.......... Hook it, saftey chain/wire and THEN tighten the bolt......... I'm doing a a bit of coursework and I've looked around the websites and cant find any that will tell me!!! How silly am I! HELP!!!! Fank chooos!
Jamtastic3 Posted June 28, 2005 Posted June 28, 2005 1 -------> hook the lantern onto the bar 2 -------> tighten the bolt to secure it to the bar 3 -------> fasten the safety chain around the lantern and bar 4 -------> plug the 15A into its socket 5 -------> begin focusing I guess. Well that's how I've been taught by my tutor anyway !!!

Proper english, anyone?And for me, it's method two. Lamp on bar, safety on, tighten bolt. That way no matter what happens, the lantern is secure. David
Penguin_Maz Posted June 28, 2005 Author Posted June 28, 2005 ahh thanks u guys, and hey, about the language, its waaaaaay to late to be thinking about that! I'm 18 and I am up at 1.33 doing coursework....really, the last thing on my mind!!! Thank you so much you guys!!
paulears Posted June 28, 2005 Posted June 28, 2005 Well it's good to see someone working that late at night.... Not like any of us have to do such things? I'm very tempted to say that if maybe you'd bothered to do it a bit earlier, you wouldn't be rushing at the last minute......... but I'd be wasting my time. I've been thinking that if we collected up all the blue room material helping people pass exams, get grades, complete dissertations etc, combined together we should have a percentage of a GCSE, A Level, BTEC or degree. Perhaps we should rename the forum Blue-Room, Bringing Backstage qualfications to everyone for free. You can buy a degree in the states, how much can we charge for our services? With Victor Meldrew hat firmly on, why does being up at 1 in the morning mean you type oddly?
david.elsbury Posted June 28, 2005 Posted June 28, 2005 PS: surely common sense would prevail and you would pick method two, especially if it's a heavy lantern? :(David
knotted Posted June 28, 2005 Posted June 28, 2005 coursework for what? C&G181? I'd vote method two, always leaving the lantern secure. hook> safety > tighten bolt > plug > focus
paulears Posted June 28, 2005 Posted June 28, 2005 Ah, but if you don't do the bolt up first, then you could knock it off, the trap your fingers under the chain or wire, which would be worse. So hook it on, tighten it up and then safety. Which would seem to me to be the least dangerous route. After all, we are choosing between a bloody big wingnut providing safety, with no chance of slipping or trapping fingers, or a bond with fiddly clip. I'll go for the bolt - but does it really matter?
sam.henderson Posted June 28, 2005 Posted June 28, 2005 My method would also be hook it over the bar --> tighten wingnut --> safety Sam
slim_mcslim Posted June 28, 2005 Posted June 28, 2005 I would add to that, ensure that the wing bolt in the clamp is undone sufficiently so that the hook clamp fits on the bar. But slightly :( thinking about safety chains, how come mirror balls require no safety chain (not practical) and along the same lines surely the yoke part of any moving yoke fixture is only attached to the motor shaft by one fixing point, how come this doesn't require a safety? The same can be said for lantern accesories, I have seen and used safeties on barn door sets, especially on large ones, but the same goes for shutters and lenses, both of which I have had drop out of lanterns when focusing them (on old poorly maintained equipment but still!) [apologies if this has been covered previously, I just posted without checking]
sam.henderson Posted June 28, 2005 Posted June 28, 2005 Have a look at a post by paulears in the safety forum at the moment, it coverssome issues of safety chaining barn doors, accesories etc. Sam
Stu Posted June 28, 2005 Posted June 28, 2005 Personally for me it's all lanterns on the bar, make sure we're happy with positions etc then hookclamp tighten up, then the safety and then last but not least the 15A plug (or whatever). I think alot of it comes down to personal preference mind... Stu
paulears Posted June 28, 2005 Posted June 28, 2005 I posed the mirror ball safety issue to someone the other day and discovered that the large ball do actually have a safety system. it is a secondary suspension via rotating swing arm. So if the main suspension fails, then the swing arm then takes the weight through to a separate safety bond. I don't think the lightweight ones will get this, but tha heavy ones are being supplied with them now.
david.elsbury Posted June 28, 2005 Posted June 28, 2005 But slightly :( thinking about safety chains, how come mirror balls require no safety chain (not practical) and along the same lines surely the yoke part of any moving yoke fixture is only attached to the motor shaft by one fixing point, how come this doesn't require a safety? <{POST_SNAPBACK}>Yes, it's practical, just rotate the ball until the safety snags, then spin it back the other way again ;) but seriously, the 40 (or was it 20) inch we brought recently has 2x rings on the ball itself and the rotator has a rotating part just around the shaft for it to attach to. I've found some mini wire rope links, about 5 inches long, that lock back onto themselves, from one of the discount chains here, and I use a couple of these to attach the ball to the safety-point- normal safety bonds won't work!

Stu<{POST_SNAPBACK}> all the lanterns on the bar? so you're talking about loading up 20 or 30 fixtures on a bar, none of the properly secured until you're happy with the position etc. not trying to shoot anyone down in flames but I can't help but find that a little dangerous, especially bearing in mind the amount a bar can flex and bounce with the extra weight. of course if you're talking about doing this 2 foot off the ground on a fly bar then feel free to shoot me down in flames! on a side note, when thinking about this is everyone answering based on rigging in the air or on a truss or fly bar floating 2 foot from the floor. my answer would be different based on which of the above I was looking at.
