Hello,

I’m in the process of building an experimental aircraft. The wingspan is 32’ (width) and the length of the fuselage (body) is 22’ long, forming a cross type shape. The height of the assembled airplane is between 6-7’ tall. I’m looking for a cost effective option to build a temporary hangar at my home for final assembly of the airplane, plenty of ventilation for making it a paint booth, and resulting with a recycled dome for camping ,greenhouse, and exhibit booth for my computer store. I’m working on a ROI (return on investment) based on my camper, greenhouse, hangar rental and having someone else paint my airplane along with using this as my new exhibit booth for my small computer store in the rural Midwest US.

I have plans to sell my travel trailer (camper) in the spring of 2009 and purchase a 20’ shelter-system dome in time for Oshkosh Wisconsin’s Air-Adventure airshow the last week of July 2009. I haven’t decided if I purchase a 20’dome as a shelter or greenhouse. Is it possible to purchase the greenhouse and a liner so I could use it for both a tent and greenhouse or put up “room dividers”?

I’m wondering if I can combine 2-3 20’ domes or integrate 2-3 domes of differing diameters in a triangular pattern to build a temporary open structure for final assembly of my aircraft. If I could use 2-20’ domes for the wingspan and integrate a smaller dome to extend the length of the 20’ dome to allow for the fuselage length, that would work too! I would need enough room to walk around the airplane inside or integrate 3 20’ domes for an open triangular structure, probably 4-6’ area around the plane to have adequate room to work on the plane.

If I could do this, then I would have an extremely flexible shelter dome system to meet the many needs I have for a temporary structure. I have also been kicking around the idea of using my dome for my computer store exhibit booth as we do local county fairs and events to showcase our products. This would be an awesome display area, but the increased costs of renting more space may be an issue too and part of the ROI as well.

Building this airplane is a dream and a long term project (5-15 years). I have a large enough home and shed to store the parts and sub-assemblies for the airplane. I would need domes added as the sub-assemblies to increase the size for final assembly.

I would like to compare the purchase of these domes compared to replacing my travel trailer (camper), renting an airplane hangar, travel to/from the hangar for 1-2 years, cost of having my airplane painted versus doing it myself, and upgrading my current display booth for my computer store.

So far, I’ve been self-convincing that these domes are the way to go, however, requesting a custom 40’ plus dome wouldn’t be cost effective or serve my multi-purpose desires. Purchasing two or three 20’ domes or various diameter domes and then use them for the temporary open area structures would make a versatile dome series and selling the remaining domes would be the optimal ROI plan.

Thank you for listening to my wild idea to help fulfill a lifelong dream to build and fly my own airplane. I’ve loved geodesic domes since my first article I read in a 1972 Popular Science magazine article that I made a copy of at the library and still have in my projects folder. I’ve already told my wife that my next house is a geodesic dome. I haven’t figured out how to make a log home into a geodesic dome, but from what I’ve seen, I could come really close to transform a metal roofed barn for my country girl wife into an efficient contemporary dome home.

My wife also tells me to quit starting new projects, but if I can improve my current projects, then I’m getting more efficient and many other things right (justification).

Have a safe and prosperous New Year!

We have joined two domes together in the past however some strength is loss and the dome/s are complicated in that a gutter needs to be created were the domes are joined.

Here is a photo near the top of the dome. The domes can be truncated and joined at the pole arches. We have not joined three but this would seem possible but again at a loss of strength.

I cannot recommend joining for your project but it may work. If you do give it a try let me know how it turns out and send photos.

I would also suggest you to make a model by cutting and joining three dome models: http://www.shelter-systems.com/modle.html

Here you can see two 20' domes joined. A fabric gutter is hung on the inside of the junction that directs water to the outside of the dome. If I was to do it again I would double up the junction poles for more strength.

Hello Eleanor,

I purchased a Yurt Dome 14' Extra Strong. By any chance, do you have a bag that I can use to transport the tent? If not, do you have a vendor you could recommend?

Thanks!

Best Regards,
Loretta

We do not make bags for the domes, as it is not possible to Stuff a dome into a bag, of reasonable size, because the covering we use is too stiff. We could sell her a 12' by 6' strip, or longer, of our fabric http://www.shelter-systems.com/accessories.html she could roll the dome in and then tape or tie it (perhaps you thew out the warper that the dome came in).

Subject: Custom application

Hello Eleanor:

I am wondering if you do custom applications. I would like to place a temporary greenhouse structure extending out from a double french door opening during the winter, so we can open the doors. If this is something you might be able to do, I will forward some rough dimensions so you can get an idea of what I am talking about.

OR, do you sell the parts so that a customized structure (within the geometric constrictions) could be designed and assembled?

--Mark

Hi Mark

We make solariums using our greenhouse covering: http://www.shelter-systems.com/solarium.html and our greenhouses can also be set up in the "Open Arch Form" http://www.shelter-systems.com/arch-domes.html which you could but up to your house.

We sell our Greenhouse Fabric and our Grip Clips: http://www.shelter-systems.com/accessories.html

Dear Bob,

Thank you very much for your kind response. Could you please let us know

-durability of the yurtdomes due to the long term base that we are intending to build? We aim to a min. of 5 years durability.
-for that lenght, do you think the standard White Shelter covering is resistant enough? what about resistant to heavy rains?
-we will be needing yurtdomes with mosquito nets and ventilation, since 4 people will be sleeping in one 20’ (do you think there is space enough for 4pax?). Are there any chances to include the mosquito nets and ventilation?

We will be pleased to listen to your comments in order to choose the more convenient yurtdome to our base (resistance, permeability, ventilation, insects protection).

Many thanks. Kind regards, Max & Laura

It is the sun that degrades the YurtDome's covering. Our Coverings have been tested in FL and AZ intense sun were it has lasted 3+ years. We guarantee it for 1.5 years since elevation also effects the aging of the covering. In Costa Rica my guess is you would have them in the shade (?) This should help increase the covering life. Water or dampness will not degrade the YurtDome's covering. It will not rot or mildew.

The dome is made without sewing so there is no needle holes to leak. The domes' covering is shingled with an overlap of 5". We offer net doors and sticky velcro to secure them: http://www.shelter-systems.com/accessories.html You might also want to consider sunshades on this page if your yurtdomes are to be in full sun.

My guess is 4 could sleep in the 20'. Look at: http://www.shelter-systems.com/sizes.html Mark a circle on the ground and put your beds etc. in the circle to see what you think. The interior is dividable; see: http://www.shelter-systems.com/lighthouse-manual.html

Shelter System's Yurt Domes can be easily divided into rooms with fabric you provide or some of the same woven ripstop material that Shelter Systems' makes it Yurt Domes out of.

First, get enough fabric. If you plan to divide your dome in half get or sew a 6' wide piece with a length equal to the diameter of your Yurt Dome. If you plan to divide your dome in quarters then get two pieces this size. Purchase 7 Grip Clips to attach your fabric if you are dividing your dome in half. Purchase 14 Grip Clips to attach your fabric if you are dividing your dome in quarters.

Fold the divider in half length wise and make a small mark at the fold on the edge. If you are dividing your dome in quarters lay out both dividers on on top of each fold in half and make a small mark the top and bottom edge at the fold. Open out the divider(s). If dividing your dome in half attach one clip at the edge mark "E. If dividing in quarters then attach a clip at "E" and "F" clipping the two dividers together at the center fold.

Next attach a clip point to point "A" on the divider and tie it to the dome's ground clip which is equal distance between two adjacent doors. Stretch divider across dome and attach a clip at the other point "A" on the divider so that when the divider is tensioned and tied to the dome's ground clip it will stretch tight across the floor of the dome. Have two people hold up and tension the divider so points "B" can be marked, clipped and tied. Run a cord up clip "E" and tie it to the top of the dome to support the middle of the divider. Have two people hold up and tension the divider so points "C" can be marked, clipped and tied to the dome at points "D". Move the clips on the divider if needed so that the divider is tensioned evenly.

If you are dividing your dome into quarters the first tension and tie your four way divider so as to divide the dome in half then pull out and tension and tie the quarter sections.

Note that once installed each divided space has two doors. If the divider is set up as above each 1/4 side will have 1doors.

You can make the divider in half sections that are clipped in the middle with two tie clips down the joined edge. There is two advantages to this configuration. One is that it saves some fabric since we can cut two halves so that one is flipped and nestled next to the other. The other advantage is that the tied closed seam could act as a door to get from one half to the other.

Sincerely,

Bob Gillis

Dear Bob,

We are building up an eco tourism project in Costa Rica, based on observation and enjoyment of flora and fauna. Our aim is to build an eco base, based on geodesic domes or yurts (still deciding), resistant to the weather conditions of the jungle and the coast (salt, humidity, heavy rain) and insects (mosquito net).

We have recently found your website and we would like to receive further information regarding the following:

-What is the main difference between your yurtdomes and domes? What is the difference in frequency between dome and yourdome?
-What type of materials do you think we could use in such a environment?
-Are all your materials syntetic, light and resitant to long term durability?
-Do you ship the yurts or domes and if so, how long does it take? Costs please? We are looking at 1 dome/yurt of 30' and 4 of 20'.

Thank you very much for the information.

Kind regards,

Max & Laura

Hi Max and Laura

The only difference between our Domes and our Yurt Domes is the name. Our domes are like the original Yurts in Mongolia: portable and light weight. Our domes use state of the art patented geodesic and tensegrity engendering: http://www.shelter-systems.com/tensegrity.html

The standard US made Yurts use very bulky and heavy components and take hours to days to put up. Our Yurt Domes should hold up well in your conditions.

Our standard White Shelter Covering would be best for you.

We ship world wide and have most of our shelters in stock (check our order desk for details}.

Sincerely,

Bob Gillis

I have an Endless Pool set into a 19’x24’ deck. I live outside of Boston, Massachusetts. I would like to put something over the pool and deck that would cut down on the heat loss from the pool and possibly also make the area around it a bit warmer so that it is not so brutal to get out of the pool. My ideal would be something I could see through so I can still enjoy being out side. I only plan on using the cover in the winter.

I was looking at your 20’ pool cover. My concerns are whether it will stand up to Massachusetts snow and winters; and how opaque it is or whether it can have wondows.

Thank you.

Susan

Subject: Re: Pool Cover

Not sure; the domes are strong and tough but are still tents (light weight and portable). You would need to heat it when snowing to melt snow off as it accumulates. The domes can fail in extreme winds. Read our wind and snow warnings.

Now on the other hand, if they do fail, usually only a few poles brake and they are inexpensive to replace (PVC).

The covering of our standard pool covers lets light through like frosted glass or wax paper. More light pass through than glass but you cannot see through it but if you hold your hand right up against it you can see it. We can make the your cover of our white shelter covering which is optically something like a sheet of paper. See the bottom of page:

Hi Bob,

me again.

Eleanor recommended to ask you for a platform. Can u help me?
I think best way is to create a platform with wood?

Thanks.

Hello Bob,
I am looking at various temporary structures for my Unit and was interested in what you company offers. I need to know if the structures are heated and/or cooled or if they are heater/Air condition ready. Please let me know either way and what our options are.

Thanks SSgt Ron

Hello Ron

Air conditioning units can be installed by cutting and taping ducts through walls.

You can install a stove as we describe in our manual: http://www.shelter-systems.com/lighthouse-manual.html

Keep all flames and heat away from your dome's covering and other objects in your dome. If possible have your stove pipe come out the back of your stove and pass through the plywood wall. If your stove pipe exits your stove at the top then place an elbow as close to your stove as possible.

Attach a horizontal section of pipe to this elbow and pass this pipe through the wall such that it will slant slightly down towards the outside. This will keep rain from following the pipe and dripping inside your dome. We recommend using insulated stovepipe throughout. Place an elbow on the outside. Attach a vertical pipe on the outside pipe and a spark arrester cap on top. Use steel wire to support and stabilize the pipe outside the dome. Loop it around the elbow so it lifts and supports the weight of the horizontal pipe. Another wire will be needed around the vertical pipe to keep it upright and stable in the wind. Tie the other ends of the wires to the dome and or attach them to wooden poles driven into the ground. The wires should be tight enough to lift the horizontal pipe so that it is centered through the hole in the wall and not touching the fabric. Local codes may require other installation procedures.

Carefully follow the instructions given with your heater. It is best if you can get a vented heater so that combustibles are expelled from your dome. When a fuel is burn it produces water vapor which will add to the dampness of your space; and carbon dioxide which can suffocate you if you were in an airtight room. The other reason is the fumes which the heater produces can smell and if burnt incompletely produce carbon monoxide (this not the carbon dioxide we mention above but more dangerous and can kill you. Now there are heaters which claim to be safe with out being vented. Read and follow their directions.

If you wish you can alternatively install a silicone stove jack and run your pipe through the jack:

Stove installation jacks and floor liners should match your stove: see the following sources. These should be sewn by hand into the domes covering at a height to match your stove.

Bob, Are the covers strong enough to ‘bridge’ across a waterfall area? We have an upper and a lower pond with a waterfall at one end of the upper pond and a tapered ‘rapids’ at the other end, both emptying into the same lower pond. A cover over the lower pond would have no support for a space of about 7 t 8 feet where it passes in front of the two falls. We only have fish in the lower pond which is what we would like to cover. We live in southern Minnesota (Hastings) and keeping the ice open all winter for gas escape is our concern. We do NOT run the waterfalls in the winter, but we have been running a smaller pump with the flow piped out of the skimmer inlet box right at the surface of the water to keep it agitated enough to postpone freezing over. We also keep a floating tank heater opposite the skimmer to allow ‘flushing’ of gasses from under the ice. I think that a 25 foot cover would give me enough coverage to be able to have a heater under the cover at one side of the pond.

Your thoughts please.

Another question. Is a 25 foot cover just a 30 or 31 foot dome without the bottom course of the wall? From the pictures on the website it looks that way.

Thanks in advance,

Bob



Hi Bob

I do not think you should have trouble spanning 8' with the 25' cover. If needed you could attach the free hanging edge to a 2"x4" . The domes and covers are freestanding, can be picked up and moved with a few people and have a stiffness and flexibility that would work in your favor. You would need to have a heater to melt snow off the dome during a storm but it sounds like you have thought of this. Yes, the 25' is the top of the 30 and 31. Let me know if you have other questions. If you decide to use one please send a photo.

Sincerely,

Bob Gillis

Subject: Hi Eleanor and Bob

Hey there,
A little report for you and some questions.
We have now done a couple of festivals with the domes now and have had a great timeso far. There have been a couple of issues that I would like to sort out before next season.
We had quite a strong wind one day and some of the pannels of the 30foot have started to tear around the clips especially around the bottom ring.
Can we order some extra fabric?

........Yes: http://www.shelter-systems.com/accessories.html If you plan to patch it you can sew on a patch over the damaged area (use scrap from your wrapper- or we can send you scrap at the cost of shipping). Alternatively the whole panel can be replaced. Glue or tape is not strong enough.

We also need some spare tubing for all 3 sizes as some are a little too bent and a couple have snapped...

You can buy class 200 PVC at many irrigation supply companies or cut to length poles from us: http://www.shelter-systems.com/accessories.html

We never recieved any spare poles for the 2 smaller ones (or any spare material either?)

.........The 14 18 and 20' domes come with 4 "door" poles that mostly only one is used, the other 3 can be used as spares. You can use the material the dome was wrapped in to make patches. We can also send you scrap material for the cost of shipping (talk to the order desk)

I realised that the poles come from Italy and get shipped to you and then back to us. Thats too much shipping really and since we are closer to the source, ... can we order that directly?

........I was not aware that our poles were made in Italy. Surely if you have class 200 or 125 get your poles locally. See above

Are there stronger versions of the poles that stand up better to the wind? It is a bit of a problem when its windy, a little scary when you have 100 people on the dancefloor and a lighting and sound instalation that is not so easy to move....

We do not recommend the domes be used in extreme wind. You can strengthen the poles some what: see : http://www.shelter-systems.com/lighthouse-manual.html But in strong wind other parts of you dome can be over stressed.

On a tecnical level,
We wanted to know how best to remove the material strips across the doors as they are a problem for drunk people .... as you may know.

........You can unclip on of the clips that holds the strip and reattach the clip to the dome. You should however when staking out your dome use the strip to measure the span of the door opening at the base.

How do you set up the entrance thing? We couldnt work it out.

........I think you are talking about the "open arch"? see: http://www.shelter-systems.com/lighthouse-manual.html Setting up you dome with the open arch does weaken the dome however and present a catchment to the wind.

Open Arch Form of your Yurt Dome
If your dome is still hot, a large cooling opening can be created by removing the poles under one of the pole arches on the side of your yurt dome and then tying up the canopy to the arch. You will first need to undo one Grip Clip from the strip at the base of two adjacent doors, then apply the Grip Clips back on to the dome. Run the strings from the inside of the dome, where there are holes on the inside of the clips, to the outside clip strings. This should drastically increase ventilation, but it will also weaken the dome in the wind. This opens your interior space to the outdoors, greatly helping to keep your dome cool. It also makes a wonderful display space for public events.)

To open the arch on the Bubble Dome: The Bubble Dome has only one door there for you will need to remove two clips to simulate another door along the arch away from the existing door and then reattach them with their connectors to the dome's side (this is so that the arch pole can be reinserted). Now the covering under the arch is free to be rolled and tied up.

To set the 31 up in the open arch form. Put the dome up and stake it out. Un-stake the stakes between two adjacent doors. Remove the poles under the arched pole that connects the two doors. Un clip the "door strip" at the base of these two doors by removing a clip to the side of each door. Replace the clip so it will not get lost. Attach 2 to 3' long cords to the inside of each of ghe clips along the arch. Have several people help you to roll up tight and hold the dome's covering under the arch. Using the long cords tie the rolled up covering to the out side clips along the arch.

Thanks
Dougal
