Michael LaVoie Posted February 24, 2006 Share Posted February 24, 2006 If I was planning on using a 12x overhead outdoors and I knew that the weather was to be windy that day, at what point should I abandon the idea of the 12x because of safetly concerns. Where is the cutoff? 15mph, 25mph? I asked the folks at MSE and even they didn't know what the average wind speed limit was for their own frames. I just want to know to avoid setting it up altogether if it's just going to be a safety hazard. Link to comment Share on other sites More sharing options...
Travis Cline Posted February 24, 2006 Share Posted February 24, 2006 12x frames are not too bad in a light breeze. If there is any real wind they can get away from you, but they're not bad if you sandbag your stands and anchor the frame to the ground or something solid on either end. Also, if the wind does pick up and the frame is not going to work for you it takes less than 30 seconds to de-rag your from and then its not really a danger anymore. So you don't have to worry about it if there is not high wind and your grip crew is half way competent. Travis Link to comment Share on other sites More sharing options...
Gordon Highland Posted February 24, 2006 Share Posted February 24, 2006 Also, between takes or during high wind speeds, you could spin them 90 degrees so they're parallel with the ground and won't catch much wind. Sort of the opposite with a microphone, you point them straight down in wind to minimize air noise. Link to comment Share on other sites More sharing options...
Jessica Bennett Posted February 24, 2006 Share Posted February 24, 2006 I'm from Miami Beach and now live in NYC. In NYC, its sometimes hard to find something to tie down to on locations, and there are never enough sand bags. Its different when there's a story about Colonel Dave in Miami holding a 12x with one hand over the ocean because the wind has picked up. All I can say is anything's possible. You have to bag and tie down tough always, but I don't give it more than 15 mph for a rag to tear at the grommits or the frame to fold. If you can minimize the strength of the wind against the rag by using it table-topped, then you can equally tie down each corner very well.

Mike Hall Posted March 12, 2006 Share Posted March 12, 2006 A couple of things should probably govern your use of a 12x12 in wind: The competence of your crew people, especially your Key Grip. If you have a good key grip, he or she will be able to tell you if flying the 12x12 is a good idea given the conditions; that is, factoring in the shot, available manpower, equipment, time, and location constraints. Since I have read in another forum here that some grips are earning $150/day, I would hasten to add that I would take the advise of a seasoned Grip first. It's my experience that persons new to the grip field may overestimate the ability of the equipment to withstand wind. If you are in a position to estimate the safety of a 12x12 completely off the cuff, I would recommend that a wind of no more than Beaufort number 5 (Fresh breeze, wind of 19-24mph) in sailing terms be considered. At that windspeed, two grown men of 225lbs should be able to safely handle a 12x12 bagged on high rollers if it is constantly held and "with" the wind.

I'd be wary of putting up 144 sq feet of fabric in a force 5, in theory it could develop 10 -> 15hp of thrust, might not sound like a lot, put think about 5 of those budweiser horses pulling on your sandbags On my little sail boat the sails generate hell of a lot of power in a force 5, (and it weighs 2 tons) Link to comment Share on other sites More sharing options...
Mike Hall Posted March 17, 2006 Share Posted March 17, 2006 Since St. Patty's day is opon us, and our Irish Friend has seen fit to call me out, I would like to reiterate my opinion that this is the "outside" edge of where a 12x12 can be flown safely, tabled, or with the wind, by two men. If need be, you have two qualified blokes of 200lbs or more that can handle a little wind, and a 12x12 butterfly in good condition that is tabled(or with) to the wind, I would bet a pint of guiness to all involved in the Tullamore Country Club that I could execute flying it safely and without harm in Beaufort 5 wind any butterfly that can be arranged. I would also hasten to add that there is an extreme difference in the US between "Force" five and "Beaufort" force five, and one might examine the difference before hastening to judgement. I do not know if this is the same in Ireland, however, a 12x12 in a BF 5 wind would still be the dog's bollux. I heart Ireland.

Rupert MacCarthy-Morrogh Posted March 20, 2006 Share Posted March 20, 2006 Ah the joys of the difference between the US and European meaning of "Force five" I thought you were all mad! ;) And a happy and funnily enoght a very wet and windy St Paddy's week end to you all, and if your ever in Cork I'll buy you that pint, but it will have to be Murphys (Our local stout) Link to comment Share on other sites More sharing options...
Michael Morlan Posted April 16, 2006 Share Posted April 16, 2006 I tried to fly a 12x12 on a rooftop on a day forecast for 16mph winds. When we experienced gusts up to 20-25mph when I told my crew to strike it. That was just too much sail for a sandbagged frame. Link to comment Share on other sites More sharing options...
