Need help with a tower structure

[shiznicks1]

Hello all! This year I plan on bringing a van with a roofrack to the playa. I think it would be much better with a small lookout tower attached to the roofrack. Nothing too crazy, maybe ten feet high or so. And of course, I need to be able to break it down so I can transport it. This will be my first structure, so I want to keep it easy and safe. Anybody have any advice on this? Ever put one up before? I think scaffolding might be the way to go, but I am open to ANY ideas or advice. Thanks!

scaffolding is way too heavy to put on a van roof. look at hunting stands at herters, cabella's, etc

you won't get something on a van roof that will hold more than 1 - 2 people.

the problem will the attachment to the roof rack

[shiznicks1]

Ya maybe wood will be a better option. I was looking at some hunting stands and they look pretty simple and cheap to make. I would like something to attach to the roof rack though. I guess I should wait until I have the vehicle with rack to actually plan. Im just excited and trying to get the brainstorming going. But if I did scaffolding, it would only have to be four supports, crossmembers, and a platform on top. I cant imagine it would be too heavy. Only a few people would be on it at a time. It will be a former school district vehicle, and they usually put pretty beefy roof rack on them.

Google up "Boy scout pioneering". Lots of ideas for wooden towers.

Strap it down to the ground, or the wind will take it.

Oh wow! I guess I never got that badge haha. Thanks for the amazing and probable resource!

[Ugly Dougly]

Probably amazing:

Maybe I will make a City Park for the Metropolis citizens.

Or a wild space preserve, fence off a square of Virgin Playa for the tourists to be amazed at.

Cow stanchions!!! The things cows put their heads through to eat hay. My friends dairy closed down and they have a bunch that I might be able to buy for scrap steel prices! Hopefully this will work out, theyll be perfect. Cheap, sturdy, easy to build and collapse, and safe. Fingers crossed

Wood is on the heavy side, but I've used it with good results. And, oddly enough, it was next to, but tied TO my van and the roof rack. Maybe a 4'x4'x10' tower? Using 4x4 supports, 2x6 horizontal beams, 2x4 decking and the steel framing parts, that almost always seems to be by HomeDepot's restrooms.
I buried each support leg about 3 inches into the playa, but also had tarp walls. Went to work a shift at the DMV, before tying it all to my van. And when I returned, a few hours later, my camp had sailed, about one foot...digging a foot long trench at each leg.
I hate em, but use serious guylines! Best of luck!

P.s. this was built on the playa

[Ugly Dougly]

Guylines can be bothersome but necessary on tall structures.
How about rebar candycane secured at the base of the posts?

[TomServo]

I've thought of driving rebar, next to each support leg...duct tape it all to gether, and no digging. I use t posts the same way with my canopy...no guylines needed. But then its not a tower.
Had a silly idea of taping foam rubber pipe insulation, about neck height, on the guylines, to prevent nasty rope burns. Its one more thing to bring, but I really hate guylines.

[Ugly Dougly]

Hang some colorful flags on them.

[TomServo]

Or that.... if a full sized van's involved, it can probably be done without guylines..just not on top of the van.

[mdmf007]

10 feet isnt too tall at all.

Build a four legged structure, and splay the legs out at 25 or more degrees, and you wont even need guy lines.

[TomServo]

Its suitable for a watch tower. I wanted to build a shower on a scissor lift..or maybe a gradall..



But then Pape material handling fired me...no free rentals

[brigitami]

I need to build a tower (not on a van) and i need cheap & easy and, as much as I would like to be, I'm certainly no boy scout

so, what IS the deal with scaffolding? There's certainly a lot of it around (both on playa and in this world). My friend said its easy to put up.....but how high can i safely go? and you think guylines & rebar candy canes would do the trick? (because i can practice putting it up here but i won't know if it will hold out there with the high winds)

[mdmf007]

When supported against a building, you can take scaffolding 30 - 40 stories high easily.

Unsupported it is still very stable, but needs to be anchored somehow. I would go more than 2 sections high freestanding, after that I would anchor into the ground, guy wires, or build a scaffolding structure with a larger footprint.

Scaffolding can be rented pretty cheap weekly, but it still adds up quickly when you add all the little parts in and sections.

One tier of scaffold can kill someone if it topples over. Don't fuck around.

Once again, thank you Bob.

The Sportsman's Guide sells a 13 foot tripod stand for about $160. It has a capacity of 300lbs, so is one person only. Even has a padded swivel seat. As mdmf007 made mention of, it has slanted legs, so guy lines probably aren't needed. But for shits n giggles, id use em. I'm sure a small art car could knock it over. For an extra $50 they sell 3foot extensions, so 16 foot overall.

I would need something that could hold more people. My objective is to provide a beacon for the lost & weary as well as being a nice place to share a sunrise with folks.

I would have smart & capable people with me to help put it up. I don't want anything fancy muckin' up our hobo jungle so the more it looks like it was pulled out of the trash heap the better. (now if I could somehow make it look like an abandoned traincar.......)

My boyfriend was thinking the double tower scaffolding with a plank joining the two would provide more support but that sounds more involved than what we may have the capability of doing.

[shiznicks1]

Pallet racking! Just came up on some for free and each tier can hold around 5000lbs. For those looking for something easy to set up and very safe, look into it. You can get it used for pretty cheap. Google/craigslist, used pallet racking.

[Ugly Dougly]

Something like this?



Not to rain on your parade, if it's used, it may not be safe to hold anthing?
Caveat your emptor, you know. Do a load-test with the neighbor's kids first.

http://en.wikipedia.org/wiki/Pallet_rack
But, yeah, it would bet leet to cover something like this with tarps or painted sheets. Make for a sort of urban look.

[Bob]

Pallet rack is probably more than twice as heavy as steel scaffold. If you happen to bring it, use lock nuts, and stake the legs & guy it off same as with scaffold so it doesn't blow over.

3/4s of the shit at Bm can kill you. Clandestine firework shows (commercial grade stuff) unlicensed home buuilt pressurized flammable gas guns, MV's built in a garage by someone who knows nothing about building anything, 250KW generators with jury rigged power distribution, food from strangers, drinks from strangers, heavy equipment bopping around at night.

Scaffolding is EVERYWHERE at BM, Do it smartly and your fine.

My objective is to provide a beacon for the lost & weary as well as being a nice place to share a sunrise with folks.

If your idea is to place a beacon atop a tower that will guide home your peeps, realize you'll be competing with thousands of other beacons. Therefore shoot for something totally unique. Something that would never be seen, or has never been done at Burning Man before. Maybe something like this:

































Oh, wait. That's already been done. Well, never mind.

Next!

The suspension of your van will make the tower wobbly, especially if you plan on driving with it attached. If you will leave it parked, consider jacking the car up on each corner and adding jack-stands underneath supporting the frame. This will eliminate any sway associated with the suspension.

Bamboo is very light and strong, and can be tied together into fairly robust forms. A strong roof rack along with a bamboo truss structure should allow 1-2 people up top...

[shiznicks1]

Ya its exactly like that pallet racking. Its no longer going on my van, that was a terrible idea, but a spur of the moment one. It will be on the ground staked in and tied off. The last thing I want to be responsible for is harming someone or their property. Its heavy, but will def do the job. and its wayy easy to set up and take down. I really like the idea of hanging tarps and sheets from it, I cant wait!

[Captain Goddammit]

A structure on top of a van isn't that terrible an idea, you get about a 6 or 7 foot height head-start, so your tower doesn't have to be as tall to achieve the same altitude. If you have a stout one-ton van it should be sturdy enough, otherwise Dragonfly Jafe is right on with the idea to use jacks under the van; they sell inexpensive little screw-top tripod jacks intended for stabilizing camper trailers that would be perfect. Until I had a one-ton truck, I used to use them under my pickup camper setup while parked at BM. Sometimes the camper didn't stay very still... dunno why that was happening... ahem.

The big make-or-break about the van-top idea is how you attach it. If your rack clamps to the drip rails, I'd be uneasy about the whole idea, but if it has plates bolted through the outer edges of the roof you'll be fine.

I always wanted to build a 2-man "Tuna Tower" on top of my Land Yacht from well-triangulated 3/4 electrical conduit, but the boat is an almost tricycle design with the front wheels only a foot apart and stability would be a huge problem.
