Tower Day at N5OT

On August 25th we had a big crane out to put up the remaining two towers at N5OT, each one 140 feet of Rohn 55G guyed in three places (40', 80', 120') with Phillystran. It was pretty spectacular. Thanks to team member Dan Droege for the photos.

This is the view that dominated the scene. The big crane, a 30-ton crane with a 100' boom from JR's Crane Service in Bartlesville, picked up the towers which had been completely assembled on the ground previously, and set them on their respective bases. In this photo, Ken, K5KA is climbing the already secured tower to remove the crane sling. (You can click on most of these photos for a larger view).
Here's another view. You can see the transit level in the foreground, provided by Arlen, which we used to get the tower as close to vertical as possible when we attached the guys to the guy anchors.
This is K5KA, and me (N5OT) on a smaller tower where three guys from each of the two larger towers all come together at a plate. My original thought was one of spacing, geometry, convenience, and cost savings (two less guy anchors), but now that it is finished, I think the words "false economy" come to mind. The guys were pretty hard to handle whilst up the tower, and getting the towers dialed in (i.e. as close to perfectly vertical as possible) is proving to be a pain, because you have to go up there to make every adjustment. Also, and this is more to the point, I have unwittingly designed in a major Achilles Heel - if this small tower should fail, it will take the other two with it. I may have to remedy this at some point.
This is me down on my knees doing the dirty work. The crane has set down 140 feet of Rohn 55 on the base, and I am making sure the bolt and hole line up and then making fine adjustments with the crane to ensure both that the base is setting flat and the tower is getting vertical. The good news is, the base IS setting flat when the tower is vertical (phew). You can see how I have approached the mounting - the towers set on a single bolt.

If you take a look at the bases, rather than spend $125 each plus shipping on two flat bases from Rohn, I had my excellent local welder Robert weld 3/8" flat plates to the bottoms of two tower sections, drill holes in the centers, and strengthen the joint with stout webbing. This saved about $200.

Once the tower is on the base, we all grab Phillystran guys and haul them out to their respective attachment points. A couple things here:

1. Per the advice of Glenn, K6NA, the guys are steel (1/4" EHS) for the 20' closest to the ground. This is a preventative measure for both fire and vandalism.

2. We had a lot of guys come out and help at the Tower Party. Some were more experienced than others. We made up three teams, one for each guy point, each team led by a ham with experience using preformed grips and handling shackles and turnbuckles and all that. The leader would call the shots and make sure everything was sano. Arlen, my friend with the transit level, and another guy (Jim and Dave shared the duty), would site the tower in two different planes and would bark directions for leveling up the tower. We learned on the second tower to do the guys one level at a time - i.e. all the 40 foot guys done and level before going to the 80s, etc. On the first tower, each team worked at its own pace, so the tower, though secure, was so prang'd that us poor guys at the guy point up the tower (figures) found ourselves having to undo and redo each of the guys because we couldn't take up enough in the turnbuckle. We are still working on getting that tower straight. The one we did second dialed right in. Lesson learned.

This is K5KA on the smaller tower with me starting up. We're about to do the second big tower's guy wires. The prang'd first tower can be seen in the distance right behind the small tower Ken is on. If you look closely, you can see the prang'd tower bending to the right the higher it gets. I guess that's why they call it Amateur Radio.
This is the best photo of the entire site. All four towers are clearly visible. The small tower between the two big towers shows the spiderweb of guy wires converging on it very clearly in this picture. The crane has been detached, the boom is retracting and K5KA is making his way back down. We can smell Travis cooking lunch.

In the very lower right hand corner of this photo, you can see a bit of broadcast tower lying on the ground right where one of the white bits meets one of the red bits. One day that big ol' tower might be called into service. For now it just waits. Also, though the light is odd in the photo (the camera adjusted itself to the bright sky and not the important radio stuff), you can see in the foreground two large spools of one-inch diameter hardline. Large cable like this is important for getting the greatest number of your watts to come out up at the antenna. Phil, N6ZZ, had to sell me about 4000 feet when he moved from Texas to New Mexico, in order to lighten his load. Larry, K5OT helped him deliver it. We OTs have to stick together!

Arlen is THE MAN with a transit level. I can't imagine how people put up towers without a guy like this on the team.
This is Clayt performing a very important function. Clayt likes techincal climbing, so when the "younger men" (we're all boys at heart, after all) amongst us got the itch to climb (and basically wouldn't leave me alone until I gave in), Clayt just happened to have all his climbing gear in the truck, and so he rigged the finished tower for belaying at the 40 foot level, and outfitted the boys with gear and gave them a lesson. That certainly gave them something to do! Thank you, Clayt!
Here's a good look at the phillystran spiderweb. K5KA is setting about adjusting all the turnbuckles. This is what I meant by "Achilles Heel" - making guy adjustments is about 5 times more difficult than at guy anchors on the ground, and if this tower goes, well, I don't want to think about it. Dang.
This is Mike, AC5P. Mike has an excellent understanding of many important things regarding rigging and towers and guys; he works for the local power company. A competent guy with commercial experience is a good one to have on the team. Thanks Mike, for sharing your expertise.
Here's the barn. Now this is a story by itself. Which I won't go into here. You can see Arlen surveying one of the towers, and most importanly you can see Travis' (Cookie) smokers just to the left of Arlen to the right of the walk door on the building. When I rolled in leisurely at 6:30am to make sure everything was ready for the crane and the crew, Travis had been there for 30 minutes already getting ready for the legendary lunch which must always follow manly events at N5OT. Smoked Meat Rushes For No Man. At 6:30am, fires were already raging in anticipation of 5 hours of smoking for a hungry crew. Thanks Travis.
One of the guy crews at work. On the right is team leader Gary, W7FG. In addition to running one of the most well-respected vintage manual companies in the Ham Radio industry, Gary also knows his way around preforms and EHS. Good job, Gary.
These next two photos show a couple of men-in-training working hard at acquiring the skills necessary for fluency in the real life world of hunting. Gatherers, if present, would be located below the bottom edge of the photo. This is Timothy.
And this is Taylor. Thanks to Clayt, these two young men enjoyed a longstanding male tradition: "Monkey See Monkey Do."
One more photo of the barn. It is 30x50, woodframed. The concrete was poured after the building was erected. This is my good natured wife Kathy jawing with Travis, Rick and Wes, KD5HBR. I say "good natured" because without her none of this would be possible. . .or necessary. [JOKE honey :) love you. . .mean it]. Wes is the guy who operated Kids' Day, sponsored by the Boring Amateur Radio Club, and immediately went out and got his ham license. Kid's Day is a great event. We hope to have N5OT on the air for Kid's Day in January 2002 with a bunch of young operators, and one "Elmer" (Ham Radio Mentor) per operating position.
And to close, here is a view in through the big door. The big door opens into the shop area. Tables, tools, parts, all that. The framed plywood structure in the center of the photo is located in the very center 7'x10' of the building, and is a small safe room (Oklahoma=tornadoes). It is built to FEMA wood-frame safe room standards. It has its own 12"x12" footings under the slab with anchor bolts every 24". The studs are 12" o.c. and the the structure is assembled with screws every 12". In the half of the building behind it (in the dark in this photo) I am building in a large (10x20) radio room, a bathroom, a kitchenette, and two bedrooms.

In ham radio-speak, I am not building a multi-multi. In fact, the station is not even designed for DX operation. In a nutshell, the design is for optimal domestic single-operator radiosporting. However, with over 20 separate antennas and 4 operating positions, it should be capable of providing training, fun, and a decent score for multi-operator efforts in any major contest. Part of my goal is to train future ops, especially young ones, which is why we are big on quality social events and facilities.

N5OT is assembled of very little which is bought new for the purpose. On the contrary, I have been saving and scrounging and salvaging and collecting stuff since about 1985 when I realized what I wanted to build. Most people who look inside the barn wonder where all this stuff was before I found the land, built the building, dug the holes, and put up the towers. That's a long story, too, and I will tell it at some point.

These folks all standing around having a good time warm my heart and make me feel like I am doing my part to make a good impression for ham radio, and to spark interest with curiosity. Lord knows we need it!
