<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>I’ve been trying to get my head around the engineering on our
pavilion project.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>Currently we could lift a Volkswagen if we were going strait
up. That’s not the problem though. We want to use the existing poles and
cabling to go between the two uprights with a cover. That is, rig something
between the uprights that can be lifted using the current cabling by inserting
a third cable between them. So instead of just going up we are introducing
tension between the two poles and, especially, the two cables. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>Anything attached to the third cable, with any weight at all, is
going to pull the existing cables toward each other. In my mind we’re going to
have a major sag in the middle if there is much weight. We also have to
consider wind. Any material that catches wind will eventually rip. Catch too
much wind and there goes the whole investment.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>Options? Canvas is just plain heavy. Weatherized material
(herculite) would be equally heavy for the size we’re suggesting. Tarps, would
work but are butt ugly. Rip stop nylon (parachute material) is very light and
strong, just hard to come by. Plastic sheeting, um, forget I mentioned that… <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>Another consideration is purpose. Are we trying to shed water
or block sunlight? Both would be nice but really what is our most common
situation? Sunlight, I’d say.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>So what might work? Cotton painter’s drop cloths might be a
alternative. They come in various sizes, block light and could be decorated,
painted, or weatherized. They also can take abuse. Check Home Depot. Another
alternative is just plain old bed sheets. King size. They are very light,
allow air to pass through, could be decorated, come in colors, are easily sewn
together, and are easily obtainable. We could get a dozen at Good Sheppard
Mission for almost nothing, or just hit garage sales.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>Anyway just a few thoughts. I’d hate to see us purchase a
warehouse of expensive fabric that ends up not working.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>As a suggestion, I’d say let’s do the bed sheet angle first and
learn from there. It’s the simplest approach, cheapest by far, and easiest to
scrap if the engineering doesn’t work out.<o:p></o:p></span></p>
