Our stock of flats are primarily Hollywood style 1x4 framed hard covered flats. During our last show I had rigged a couple of the flats by drilling through the top rail and internal toggles and running GAC to a D ring bolted onto the bottom rail. The Facilities Manager has told me that I must run the cable down the sides of the flat to some form of bottom hanger that attaches underneath the bottom rail. That this "bottom attachment method is the only acceptable way of rigging anything". Is my method acceptable? is he correct that bolting to the bottom rail is not enough and that you must pick up beneath the bottom rail? Thanks in advance.

Thanks in advance. The main point that he is correct on is that lifting from the bottom of the flat is the way you want to go. As long as the stiles aren't Swiss cheese, drilling a hole for GAC will not interfere in their stability. A good option would be to have a steel plate under the bottom rail, at the point at which the cable would go through, and then sending a forged eye though the bottom rail, threading into the plate. Attach to the eye with a turnbuckle, and you have adjustability and concealability. The worry about bolting through from the top is that the load is concentrated on the bolts as opposed to being distributed over an area. Given a shock load, there is the possibility that the bolts could pull through or fail (unlikely). That being said, you could use the above mentioned plate and bolt through it, sandwiching the rail between D-ring plate and bottom plate. That way the load is distributed over an area, and the rail is reinforced.

You say you "bolted" the D-ring to the bottom rail, so I assume you mean that the bolts ran completely through the bottom rail. If so, you are lifting from the underneith the bottom rail since the the heads of the bolts (and maybe some washers) are below the bottom rail. Since the stiles rest on top of the bottom rail, and the top rail rest on top of the stiles, the entire frame is in compression, which is what you want. Now if you had attached the D-ring to the top rail, it would be in compression, but the rest of the frame would be in tension. This would have been a bad choice, but you did not do it this way. -Delbert Delbert L.

Thanks in advance.

Turnbuckles overhead? Not where I can help it...at least not unless it's a completely static application. Even so, and while this would be an extremely secure procedure, it is something of overkill (and here's the caveat) unless the flat itself is rather substantial in weight. It depends on the application here, and the size of the flat. Some very lightweight ones I've made have been flown by attaching the GAC to a good (and carefully-installed) screw eye rather than a bolt...but I wouldn't do that with something 8'x22'. For a piece of that magnitude, I might instead attach a steel plate beneath the bottom rail, drill through both the lumber and the steel, run the GAC all the way through, and terminate it with a swaged stop. Just another option... I guess what I'm trying to say is that I'd probably, if I were in your shoes, object less to the FM's insistence upon bottom hangers and more to his propensity for blanket statements like this. There's more than one way to hang a flat safely, but you have to have a good grasp of the principles involved... > The worry about bolting through from the top is that the load=20 > is concentrated on the bolts as opposed to being distributed=20 > over an area.

That would seem to be the weakest link in the system here, but we also (should) have a fairly good idea of what sort of forces are involved in breaking a stick of 1x4 that way--which then allow us to factor that into the decision process. The shock loads would have to be reasonably large--which also means that it either has to weigh a lot on its own, or have some goodly amount of mass attached to it (or strike it) while it's in the air for this to be a concern. IMO, of course... :) And, as Delbert alluded to, rigging flats is like you and your significant other...being in compression is a lot better than being in tension! ------------------------------ Subject: RE: Rigging "hollywood" flats Date: Wed, 12 Jan 2005 09:17:14 -0800 Message-ID: <407DF7D68DD30440B5CEB70ED234D1CF0316E2D2 [at] excuswa100.americas.unity> From: "Cyr, Dale" dan: any chance of seeing a picture or your arrangement? specifically the point of attachment at the bottom?

It might be acceptable on a very, very light and small prop but even then I would prefer another attachment. I would rather trust the turn buckle than the screw eye. Now that that is off of my chest, I have rigged Hollywoods just as originally described with a D-ring on the top of the bottom rail & bolted through and have also supported the bottom attachment with other than just the 3/16 bolts through the bottom rail.

What I failed to include was a note to the effect that I never, when using such beasties, use anything other than the forged ones with a whole "eye". In that sort of scenario, the only practical risk of failure is in the screw portion pulling out of the stock, rather than a failure of the eye itself. I would never recommend the cheapie malleable ones for anything...hell, I don't even use them at home! :) > I am also interested in what the list has to say about=20 > attaching Hollywood flats at the bottom of each stile instead=20 > of the bottom rail. I know, logically, that if you rig it this way that the only thing in tension (on the flat itself) is the bottom rail; and that the only thing pulling on it is its own weight. But it isn't something I do, just because it doesn't feel right in my gut, y'know? I figure that the rail is there for a reason, and the flat is constructed with the rail supporting the sides, so I lift from the rail. ------------------------------ Message-Id: In-Reply-To: References: Date: Wed, 12 Jan 2005 16:47:28 -0500 From: "richard j. archer" Subject: Re: USITT List members, Anybody know what parking costs in Toronto , say at the Convention Center, if I'm not staying at one of the convention hotels? thinking about it now before students arrive back from break.

Aluminum sleeves work well in situations where there can be no signficant shockloads on the cable. Aluminum breaks under repeated shockloading much sooner than copper or steel. For performer rigging, I always use copper sleeves. Some quicklinks (aka rapidlinks) are load rated, but most are not, so most people just rule them out totally for overhead lifting. This is probably a good practice unless you know that your quicklinks are load rated. -Delbert Delbert L.

If I am not sure of the manufacturer, I assume the rating to be the breaking strength. Even if it is stamped as WLL. At that point I use the hardware in the appropriate fashion with the appropriate safety factors.

Some high end sailing equipment vendors also sell stainless steel quicklinks that are load rated. There are certainly other vendors who sell rated quicklinks, but the ones sold in most hardware stores and industrial suppliers (like McMaster-Carr) are not rated for overhead lifting. Dispite this fact, quicklinks get used for many rigging applications. Even equipment manufactures don't always follow the guidelines set by other manufacturers whose components they use. For example: wire rope manufactures recommend that the D:d ratio of a sheave be a minimum of 25:1 for 7x19 GAC. They also state that a D:d ratio of less than 16:1 will in a cable life that is relatively low. This not only reduces the life of the cable, but also decreases its strenght efficiency to 86% of that stated by the manufacturer. I saw a new cable hoist in a store on Monday where the D:d ratio on sheave was approximately 10. Of course the manufacturers of the hoist did state that the hoist was not to used for overhead lifting (etc) - so they did cover their asses. -Delbert Delbert L.

It soaked my sound rack too! If the water was clean, you might be better off than you think...If it was dirty, rusty, etc... you might be best off rinsing the stuff with clean water. Water doesn't hurt the stuff half as much as all the crud that was dissolved in the water will. Put it all under some pars to dry nice and thoroughly. Power cubes will fail if shorted while on, so be prepared for a few of those, anything that gets hot, or is bolted to a heat sink might have been thermally shocked by the water. I'd try to get the insurer to total it because you never know if it will be a source of recurring corrosion and stressed component related failures for the next 20 years. Be glad you were there and it didn't happen the first day of break! Good luck!

Fortunately, in my main venue, the dedicated HVAC for the dimmer room is all beneath the floor. One 3'x3' metal grate in one corner for supply and one in the other corner for return. Only problem is we loose small objects down the grates. Since the room also is used for sound storage, there's a fortune in connectors, maybe even a few microphones down there. Reminds me of one of my computer stories. [Oh no. Here he goes again with his war stories.] An HVAC unit was dripping on the top of a major mainframe unit. So the brilliant operators put one of those 5 gallon size office trash cans on top of the mainframe to catch the water. Nobody ever bothered to empty it. So rather than an occasional drip which really wasn't doing much harm, the can filled with water at about the same time the plastic grate on top of the cabinet reached it's weight limit. Amazing how that worked out almost exactly, the plastic top could hold 39.9999 pounds. Talk about the drip that broke the computer's back.

Quick, quick quick, while they are still wet, rinse well with distilled or deionized water. ( Available at walmart by the gallon. ) The AC system water probably had all kinds of possibly corrosive and or conductive contaminants in it. What spilled on it? Condensate water ( relatively pure, except for dust/grime/mold ) or chilled water loop water? ( Relatively clean, but usually has various treatment chemicals and dyes in it. ) Then blow dry with *low* pressure air. ( High pressure air jets on components can screw up mechanical connections and break fine jumper wires. ) --Dale ------------------------------ End of Stagecraft Digest #258 *****************************
