Steel doesn't stretch very much. Big surprise!
A sixteenth of an inch is this shop's "shop tolerance". Meaning I typically measure to the nearest 1/8" and things start wobbling around. When the spider was constructed, I tried very hard to make the pipes EXACLTY 45 degrees but I was only measuring over a distance of 10 inches - when you are off by a little bit, and you project forward 10 feet, that little bit turns into a big deal. I dont know how NASA does it but they do. The net result is that as you go around the 8 sides of Devoted, eahc side is a little different - a little more or less than the average distance. And, since steel doesn't stretch like rope does, there was a lot of measuring and rechecking the past two days...
In a prior lifetime, I ran chain for a surveyor and tried to learn what I could in the process. It was a great summer job, and I was a pretty good go-fer. That is when I learned about closure error. If you are laying something out in a closed loop, you should end up where you started from. When you don't you have a closure error that indicates your measurements are off somewhere.
I am happy to say that Devoted closes! The various braces and sign mounts are dimenstioned correctly; you can hook all the pipes into a loop and end up where you started, not pulling really hard on a pipe and wishing it was made of rope instead of steel.
I had originally hoped to depart tomorrow am but there is still a fair amount to complete on Devoted - and I do not want to be doing any fabrication on the playa. Assembly, yes; construction, No. So far, I am doing pretty good at building Devoted by myself. Haven'd dropped anything on my head yet, but am wearing a hard hat!
You know, Arizona still has a law on the books that you can hang a horsethief or cattle rustler. I wonder if it applies to bicycle theives?
Some bad person or persons jumped our chain link fence and carried off my burning man bicycle - a wonderful extravagance that was a real pleasure - a belt drive bicycle, perfect for the Playa. They had to carry it off because there was a chain through the wheel and fork. My new ride is very nice - the price was right - and it only took a little while to put together.
Sarah has contributed a flag for the top of "Devoted" - I can't wait to get it on playa atop the Temple of the Devoted.
I'd like to thank all of you who have backed the creation of "Devoted". Larry Edelstein, one of your fellow backers, came by for a site visit to make sure that all these pictures are not just photoshop! Larry will be at Burning Man in a week or so, and I hope that Devoted is all set up and ready to go.
Really, I expect that I am about 2 days behind schedule. Fortunately this week is free from work and I am not going to leave till Devoed, and Shots FIred, the expresso machine, are ready to go!
Next post will be of a fully loaded U-Haul trailer heading out of the driveway!
Thanks again for your support. Project may not be done on time, but it is on budget. Thank you for your support -
