Rollers, folders.... all asking for trouble. Why not a garage-door
style door, single piece and folding upward with help from low-tech springs? That's what we recommend for county hangars. Very low maintenance, can be automated, and don't flop around in the wind. My opinion only, of course. |

We have a large one of those on the hanger we're in at the moment, on the order of 50 x 25. No springs; a series of cables runs from the top of the door to a large counterweight; attached to the bottom of the counterweight is a cable to a _small_ winch (of the sort usually used to move small boats onto trailers) that is used to raise and lower the door. It works great; I just don't want to be around if the thing ever decides to let loose. From the looks of the counterweight the thing isn't precisely "light". |

How can you get a 40 ft garage style door to work properly. Can you imagine
one track holding each end. Wouldn't the midlle colapse when in the up position? J.P. "Musky" wrote in message ... Rollers, folders.... all asking for trouble.

Sometimes an aircraft can be locked in for months. George Patterson This marriage is off to a shaky start. The groom just asked the band to play "Your cheatin' heart", and the bride just requested "Don't come home a'drinkin' with lovin' on your mind". |

Very low maintenance, can be automated, and don't flop around in the wind. My opinion only, of course. Mine is a single piece 50 ft "garage-type" steel door with a residential door and six residential windows in it. It is suspended on cables and guided by two parabolic curved tubes. Every time there's an earthquake slight alignment problems delvelop and the side rollers take huge stresses and snap apart the sides of the building. The side rollers attract dust and are high mtc. But it allows me to have windows and a man-door which is nice. But for dependability I'd have gone with an electric bi-fold if I had to do it over again. pac |

Why couldn't they use salt to melt the ice?
