@@enermaxstephens1051 I think plastic. Metal is problematic. If you paint the plastic barrels black they absorb solar heat more efficiently. Plastic doesnt rust and are indestructable to everything but fire.
Years ago I made a Yurt for under $700 and thought I could get the cost down a lot more if I used PVC instead of wood. This is a start to a nomadic home that could be completed for *real cheap*. Thanks for this video.
This reminded me of the day I looked at my eight sided PVC pipe kiddie pool, which had just ripped, and wondered what to do with the frame and legs. I took it apart and scattered it on the lawn and moved the pieces around like DNA. It came to me to create a house shaped structure . I had a piece of PVC under my sink just big enough to cut into pieces that fit perfectly as straight connections for the pipes. I had the elbows from the pool for corners. It made a little greenhouse structure. And since I have no talent for this kind of thing, I felt like it was some kind of miracle that I had such a perfect outcome. I think a real geodesic dome would be so fun to make.
What a great idea. If one uses this approach to build an air crete dome, one can eliminate the need for the ballon and air pump needed to inflate the dome. Essentially, one would would build a dome (using your technique) of the desired size, tarp it, spray on the air crete or foam-crete, mesh it, and repeat the process and voila, an air-crete dome home.
Love this. With 2 layers of plastic and a mesh wire layover roofing inside you could grow indeterminate tomatoes year round. I saw the mesh ceiling for tomatoes on a video several years ago for year round tomatoes being grow inside an office building. I love this.

Great video, thank for sharing. Just a thought about the center connection with the cross tee alternative. You could use a heat gun to deform the pipe and flatten them, drill a hole and then connect them with a smaller carriage bolt. Similar to the connections on a scaffolding pipe.

Some softer materials can't be used through the winter because of snow load, but to extend the spring and fall this would be good. Can always exchange the pipe for stronger stuff as you can afford it.👍
I built this dome and learned that you could make one any size you want by using larger pvc to the make the circle base instead of the trampoline part. I made a top out of two large PVC caps so all the ribs came in at the same height. Would send you a pic if I knew how.
Brother Charles has been doing electrical work for well over 40 years, I've done construction for well over 40 years, and you're correct they do not make a four-way Gray, there's an reason based on code, you have to use a junction box, which by the way would make it look very pretty and sturdy. Yes it has four sides, with three stab holes on each side, at least four elbows at 45 degrees will be needed. This would make a great greenhouse indeed.
Self-tapping screws do not require pre- drilling. Just make sure you have no movement between parts when drilling through 2 pieces. Also keep it mind the size of your screw and the hardness or thickness of the metal. SD screws are the bomb when used correctly. I strongly reccomend using a hex head with an adjustable torque driver.
Another Good use for Trampolins is to dry your harvest (Tomatos for example). Its easy to clean with a pressure cleaner and the nylon fabric is really strurdy and let a lot of air thru. Good its still plastic and perhaps not the best in respect of endocrine disruptors,... but it's working and you can cover the upside with a mosquito net against flys...

Excellent video! For the centre hub I just cut the rim off a child's bicycle wheel (free) and pushed the pvc onto the wheel spokes. Just need to find a wheel with the correct number of spokes ....
Suggestion Re hub: You could make an interior "ring" with small connectors which have 30° or 45° angles and use those to link Ts to the ribs. I see a lot of places where your outside frame connections are going to wear against the plastic cover. There is a tape you can apply to the connecting parts that prevents such wear. The cover should be 6 mil. plastic. Greenhouse catalogs carry it.
Hmmm! I have been thinking about building steep basement window-well covers out of pvc pipe, for our deep snow to easily slide off, and it seems like a narrow half-dome similar to your design might be do-able. Thanks for the ideas!
for the top where the pvc crosses, use 12 tees connected in a circle , using a heat gun for the bends y short sections of pic. Connect all upright sections to the pvc tees.
You can use a old round BQ grill for center attachment support. Drill holes around the edge. Pass the pipe through and secure them together. You can drill 2 holes a couple inches from end of pipe and then pass a wire or rope through all hoels and tie together. One would be on outside and othe would be on inside so the BQ grill would stay in place. The 2 holes only need to be 1/2" or so apart. If you could 3D print something or have someone make that instead too.
So in regards to the center peak issue, take a piece of 3/8 plywood and cut a 12-inch disk. Then take a length of PVC that is a 1/4 inch larger than the pipe and cut 6-inch pieces and screw them to the disk so that they match with the ground and then jus glue it up. I would spray the disk with some spray paint to make it more moisture-proof
That may be too simple/easy for some thinkers here, bad joke-(*Great Idea)✅ Possibly utilize treated plywood and paint, woodglueinto small predrilled holes and theres a nice joint to enjoy
You could have cut a dozen short pieces of pvc in the size you need and equally space them into a star, sandwich between two round pieces of plywood and some screws and you have a big coupler.
I’ve already got a geodesic dome made from roofing battens and purchased hubs but I’m so impressed with this I’m going to make this too! I have a dead, 12 foot trampoline.
I would have used the springs and spring holes to keep the circular base together. But this is a hell of a great idea. Definitely going to use in the future.
You can use the leg hoops for a row cover pound some rebar into the ground and slide the ends over the rebar cover and plant later you can take the plastic off and put a row cover on to keep the bugs out
You folks are very encouraging and that's one of the reasons I watch these kind of videos. People when they are kind thoughtful and helpful really touch my heart. Thank you all.
There are 2, 4, 6 gray electric junction boxes. They have threaded holes though and are most common in 3/4" size so you will need to glue slip to 3/4 thread adapters onto the pipes to attach them to the boxes. Hope that gives you an idea. You might get away with 2 six port boxes to make it simple.
A friend of mine built a geodesic structure similar size to this by using plastic plumbing pipe like he showed, but she carefully dipped the ends in a pan of hot oil and them squashed it flat with some pliers, then drilled holes when it had cooled. Would be able to use instead of all the Ts in this as she then attached those in the shape she wanted with nuts and bolts and it worked to make a dome. Maybe try it out.
You know, the Mongolians designed really amazing toppers for their dome topped yurts called Toonos. They use a stunningly hand carved wheel pattern from lumber to design toppers that fit all the pieces together perfectly. You cannot order PVC Toonos from Lowes though. The Khazakstan ger provides a simpler way to connect the top ends. IDK, sometimes it's hard to figure out how to make the top of a dome work. The Duomo in Italy took over a hundred years to build, and the architect that planned it died without telling anyone how to finish the top. The architects that built it were all drunk and swinging in the air, not knowing what to do. They had a contest for any of the renaissance artists to find a solution. Only one person, a reject from society could figure it out. I'm impressed that you think for yourself and find creative solutions. Never limit your life's options to receipts from big box stores. Commercial worlds will always fail you in the end. I retired at 35. Then I opened a business again a month ago, and it looks like I get to quit again and runaway to the wild next month, so I am happy to know how simple it is to make a greenhouse dome in an afternoon. -Former Underpaid Disgruntled Lowe's Cashier
Make your own fitting. Get 12. 1 inch grey couplings primer them make them into circle pour glue over them flip and repeat. Take two metal Coffee can lids for reinforcement puts some bolts thru.
This is a great plan. Thank you . I live in high wind area and it would be great if you oould come up with anchors for the bottom because the wind would lift the whole thing and wheel it around the pasture. Blessings and safety to you all.
Don’t forget the rain barrels used to keep the place warm when that’s needed! I grew all year long Tucson Arizona, ok grow for 9 months out of the year as I had no way to cool it those summer months by eleven am it was 85% shade and still was all the plants could to stay alive but stay alive the five tomatoes one Cayenne pepper that were five year old. I just had some old cooler filled with water I’d cover the flat roofed structure with just Six mil visqueen plastic from Home Depot I got three winters out of the plastic. Keep in mind that in Tucson every day by 10 o’clock the plastic came up on the west side and over opening all the south and west sides or everything would have cooked by 4 I closed it up kept all branches from growing plant got about 8 feet I would untie and coil the plant down on the ground. Those tomatoes, one just sliced in half and you would smell it from the back of the house right away!
What if you just turned the trampoline upside down and only taking the legs off using the jumping surface as a floor, that will keep things together, and just cut slits or small holes where you want to plant seeds. And about the connections up top! Take a disk/circle of wood a bit thicker than an inch. Take how many connections going to the top divide by 360, get a protractor and mark off by degrees where the pipes will meet. Use a hole saw that will leave a one inch inner diameter, and if the thickness of the hole saw bit leaves enough room for the PVC to slide in then no more work is needed else attach sand paper to the outside of the hole saw bit or cut away extra material so the thickness of the PVC can fit! By the way, you know you want to love ❤️ this comment! LOL
Killer means of beating the money-grabbers ! Way to go and thsnks for thd tip ! I picked up 2 of the 2v geodesic playground domes. I reconfigured the strut sizes and am replacing the struts with 5'3" and 4'7" size galvanized 1". Building a multi-level Geo Cabin out of it with a south facing grow bed up front similar to earthship design. So really I'm just repurposibg the hubs- but it's a no-brainer for mathematically challenged folkes like me. I kinda got my marbles rearranged by an IED on convoy a whike back.

A dome, but not geodesic. They have formulas for any size geodesic dome. Using even thin steel conduit you could have ended up with a much more rigid structure, bolted together at the junction points. I doubt it would have cost $250.
@@fukkawi ...Desert Domes is one. www.desertdomes.com/domecalc.html There are others. You go to their geodesic dome calculator, you enter the radius into the box and it will instantly tell you how many struts you will need and what sizes they need to be, center of bolt hole to center of bolt hole at the other end of the strut - so, if you're using steel conduit, you cut the struts maybe 2 inches longer than the measurements and drill the holes the distance apart indicated by the dome calculator.
I also agree: A geodesic dome is specifically constructed from repetitive triangles or other polygons. But, there is some good thought into this project. A couple of thoughts: First of all, the bottom ring can be made from thin-walled 1" steel conduit and couplers that is bent into curves adequate to form into that form the desired diameter ring. A sheet metal shop would not charge much to run the straight lengths of tubing thru their bending equipment...and they would be able to calculate how much of a bend is needed to form the proper diameter circle. Second thought is that I agree that 2 x 6 way connectors would be a better idea at the top center point. With careful measuring, 3 x 4-way connectors could be cut apart with a jig-saw, such that they have 60 degree angles at the join end, and glued back together into 2 x 6-ways connectors. This were the concept of PVC glue is an advantage. Unlike most glued joints, which are weak point, pvc joints are as strong as the things glued together, because the glue literally fuses the joined parts together. However, to avoid all of this "fiddling", it is easy to find 6-way connectors online...specifically designed for actual geodesic dome construction. A quick search online will disclose some expensive ones (@$26), but also will disclose sources of more affordable "Sonostar" connectors for as little as $8.99 on Amazon.
Brilliant! New to your Channel... great stuff; and I’ll be sharing this diy geodesic greenhouse build with my sister; whose kids’ trampoline now has an exciting future!
If you can get the grey pvc in a four-inch size, cut off a piece about 3 to 4 inches long and then drill holes in the sides into which you can insert your pvc pipe. Drill small holes in the pvc pipe and use those to attach the pipes to the hub with metal zip ties. Look at Zip Tie Domes for an example.
On another channel they took a 10 inch wide pvc pipe and used a hole drill to drill multiple holes around the circumference instead of using a T connector.
You can use two wooden or steel circular plates and just screw the pvc pieces between the two at the peak for a sturdier connection of all the hoops, otherwise great design.
I didn’t retire at 40, but, did so at 42. Went into military at 18, stuck it out. Many called me lifer, many said they wished they had been with me, especially the ones I met thru basic training, went thru tech school, got assigned to the same bases, worked on the same jobs, all could have retired at the same time. Except one good friend, he was killed in a car accident. Pay heed enlistees, this could be you!
i priced 1” PVC yesterday… almost $20 a stick everywhere. That’s 500% inflation since you made this video. Wood and steel is close to the same. Unreal.
Excellent. I liked it. If I had the land space, I would build one based this model. Living in Florida, I'd probably use two rings of support like you suggested and anchor the base all the way around to the ground.
As for the "cross" fittings, make one in the woodshop, the scrap plywood and dimensional lumber is also free and instead of having to buy 3 fittings you have one piece, and you could use it as an anchor point if it's heckin windy in your area.
Maybe a 3D printed cross-t? Or a sandwich of circles with a bolt through the middle, and the pipes attached radially, if that makes any sense.. so it would almost be like a basket construction upside-down.
Greenhouses are necessary where I live if you want to grow anything besides cold crops and berries. I didn't want to spend the money on a green house nor build a so-called 'cattle panel' or 'pvc' greenhouse. I wound up buying 15-16 pieces of 2"x2" and making a 4 ft tall by 4 foot deep by 8 ft wide oversized cold box that sits atop a 4x8 raised bed. The front is hinged at the top of the box to access the plants - and at the bottom of the back panel so the box can be tilted off of the bed box. My reasoning was simply "why is it necessary I be able to stand or go into the greenhouse? It only needs to be big enough for what I plant." It takes a bit to work out the dimensions to fit it all together. Clear poly is wrapped around and stapled to the 2x2's, the 5 pieces (4 sides and 1 top) are held together with decking screws through 1" diameter fender washers so as not to pull through the poly. I think the enclosure was about $30 (I used hinges I already had, and some hook and eye latches) and the 4x8 raised bed made from 2x12 ground contact lumber was about $60? It'll fit 4-5 tomato plants. Congrats on the early retirement. I retired from the aerospace industry at 43 in 1998. They got enough of my soul. The rest is mine. Best to you!
You gave your mitre saw so take some grey pic, cut the proper angles and glue together making your spider. Just an idea. I know gluing tat stuff together is tough. It could be reinforced with a metal ring or a pvc reinforcement plate of sorts. Great idea you have there, Thanks Kindly! DaveyJO in Pa.
Helpful hint, you can shape pvc by filling it up with hot play sand. Stick sand in the oven, seal one end of pipe temporarily, fill with hot sand, shape, let sand cool down, and voila.
I would have used the sections of galvanized steel sections that were the “legs” for the trampoline, which could be used to raise the height of the whole structure, ... in other words, just flipping the trampoline upside down would have worked much better to secure the size of the “dome” overall, ...
@@live.life.simple. when the video showed you had cut the legs off, I went "oh what?😱!" You cut the legs off!!!!" How will you make it big enough inside to stand up??!!" 😵 Anyway there will always be several versions until you get to the fully executed idea! It's all good👍
Fiberglass tent poles work great too. I drug out my tent, realized it was dry rotted so it was turned into a quick greenhouse. Shoved the poles into cinder blocks to keep the arch. Threw plastic over it and more cinder blocks to hold down plastic. Then threw some lacing rope over it to help hold down plastic and tied it to the tent stakes.
Then you have to deal with some other way to mount the electrical PVC. Maybe a hole saw to put holes in the bottom of the "legs" of the trampoline? Wouldn't be quite as easy to do.
@@live.life.simple. if the legs are used for height, how would this effect the amount of poly needed as you mentioned that 20ft x 25ft was originally needed
What I would have done is make a hub for the center of the dome by gluing some 2x stock into a piece which I could drill 12 1" holes at 30° deep enough to receive the 1" pipes, but not all the way through, and set the pipes with deck screws. You could even get fancy and bevel 12 pieces at 30° compound angles, so the holes could be drilled at 90° to the lumber, but would flare at 30° from center. If you do this, you can install a vent at the center of the wooden frame, which is very useful for hot days.
Brother great project, but can I make a suggestion? I saw a guy use galvanized steel electric pipes. What he did was use a press to flatten the ends and put them together much like the way playground domes are. PVC will compact easier with the help of a heat gun and a vice grip. If you wanted to really streathen the structure more, you could drill the PVC pipe every foot or so and fill the pipe with expanding foam on the inside of the pipes. Youd be amazed at how hard it gets. Obviously this is done on the interior PVC and once built, as youre not going to be able to bend sh.t after you foam the PVC. Also if you can get the frequency of the dome small enough, you could buy old projection tvs fresnel lenses, to increase sunlight. Ideally youd want a tank of water inside also heated by the lenses. This will keep the enclosure warm at nite. Fish are dumb, but you could keep brine shrimp in the tank. Scoop up a net of brine and make brine burgers. Hope this helps and thanks for the vid.
My dude, really nice idea with the trampoline base! :D What you could have done for the top connector though is just put 4 cross-tees into the center cross-tee, that gives you 12 incoming :)
A small piece 4" or "5 long piece of 6" pvc pipe with holes drilled in the side would make a great center piece. Screws could be added in the pole sections to keep them from coming apart. Great video and ideas ... thank you!!!

Look at Zip-tie Geodesic connectors. They're basically 4inch or 6inch pvc pipe rings with holes and the pipes meet in the middle.
Just what I was thinkin 👍

You folks are very encouraging and that's one of the reasons I watch these kind of videos. People when they are kind thoughtful and helpful really touch my heart. Thank you all.
You're so clever! Thanks for the inspiration!! 😊
You gave away 3' of vertical wall by not using the trampolines feet. Use it upright and join the hoops to the ring. It would also be stronger.
You're right. Good thinking
I thought he was going to use them for extra support at first as well.

Yeah! Well spotted. A lot less cutting too.
How would you attach them?
@@k1lyth Tee pipe/tube clamp or chop a plastic t fitting in half across the long side to create two tabs then screw them to the ring.
Very nice project. Thank you for posting. Try a circle at the top and join all the poles to T's. Would also allow for vent.
The stretchy part of your upcycled trampoline makes a great shade cloth- and pvc makes great giant hula hoops! Duct tape for color…
Great idea!!
There are 2, 4, 6 gray electric junction boxes. They have threaded holes though and are most common in 3/4" size so you will need to glue slip to 3/4 thread adapters onto the pipes to attach them to the boxes. Hope that gives you an idea. You might get away with 2 six port boxes to make it simple.
A friend of mine built a geodesic structure similar size to this by using plastic plumbing pipe like he showed, but she carefully dipped the ends in a pan of hot oil and them squashed it flat with some pliers, then drilled holes when it had cooled. Would be able to use instead of all the Ts in this as she then attached those in the shape she wanted with nuts and bolts and it worked to make a dome. Maybe try it out.
Super two thumbs up. Magnificent job, thanks for showing it.
Awesome and amazing

You know, the Mongolians designed really amazing toppers for their dome topped yurts called Toonos. They use a stunningly hand carved wheel pattern from lumber to design toppers that fit all the pieces together perfectly. You cannot order PVC Toonos from Lowes though. The Khazakstan ger provides a simpler way to connect the top ends. IDK, sometimes it's hard to figure out how to make the top of a dome work. The Duomo in Italy took over a hundred years to build, and the architect that planned it died without telling anyone how to finish the top. The architects that built it were all drunk and swinging in the air, not knowing what to do. They had a contest for any of the renaissance artists to find a solution. Only one person, a reject from society could figure it out.
I'm impressed that you think for yourself and find creative solutions. Never limit your life's options to receipts from big box stores. Commercial worlds will always fail you in the end. I retired at 35. Then I opened a business again a month ago, and it looks like I get to quit again and runaway to the wild next month, so I am happy to know how simple it is to make a greenhouse dome in an afternoon. -Former Underpaid Disgruntled Lowe's Cashier
Make your own fitting. Get 12. 1 inch grey couplings primer them make them into circle pour glue over them flip and repeat. Take two metal Coffee can lids for reinforcement puts some bolts thru.
WOW!!!! What a great way to repurpose trampoline frame.!
Thank you for posting!!!!
This is a great plan. Thank you . I live in high wind area and it would be great if you oould come up with anchors for the bottom because the wind would lift the whole thing and wheel it around the pasture. Blessings and safety to you all.

Don’t forget the rain barrels used to keep the place warm when that’s needed! I grew all year long Tucson Arizona, ok grow for 9 months out of the year as I had no way to cool it those summer months by eleven am it was 85% shade and still was all the plants could to stay alive but stay alive the five tomatoes one Cayenne pepper that were five year old. I just had some old cooler filled with water I’d cover the flat roofed structure with just Six mil visqueen plastic from Home Depot I got three winters out of the plastic. Keep in mind that in Tucson every day by 10 o’clock the plastic came up on the west side and over opening all the south and west sides or everything would have cooked by 4 I closed it up kept all branches from growing plant got about 8 feet I would untie and coil the plant down on the ground. Those tomatoes, one just sliced in half and you would smell it from the back of the house right away!
Have the hoop connector 3d printed in bulk easy fix and make money. Great video
Excellent, saved your video. Now on the hunt for an old trampoline!
What if you just turned the trampoline upside down and only taking the legs off using the jumping surface as a floor, that will keep things together, and just cut slits or small holes where you want to plant seeds. And about the connections up top! Take a disk/circle of wood a bit thicker than an inch. Take how many connections going to the top divide by 360, get a protractor and mark off by degrees where the pipes will meet. Use a hole saw that will leave a one inch inner diameter, and if the thickness of the hole saw bit leaves enough room for the PVC to slide in then no more work is needed else attach sand paper to the outside of the hole saw bit or cut away extra material so the thickness of the PVC can fit!
By the way, you know you want to love ❤️ this comment! LOL
Nice info, much appreciated
Lots of wind in DFW area Texas. I have a free trampoline and the circle frame will do better than the long tunnel type!! GREAT JOB!!😊
That is awesome!
This was the video that got me into your channel! Thanks again for the great idea!
Killer means of beating the money-grabbers ! Way to go and thsnks for thd tip !
I picked up 2 of the 2v geodesic playground domes. I reconfigured the strut sizes and am replacing the struts with 5'3" and 4'7" size galvanized 1".
Building a multi-level Geo Cabin out of it with a south facing grow bed up front similar to earthship design. So really I'm just repurposibg the hubs- but it's a no-brainer for mathematically challenged folkes like me. I kinda got my marbles rearranged by an IED on convoy a whike back.
Will check your part two.
Take care, brother, & thanks !

Just paint your white pvc cross and it will extend its life a lot.
How does painting a white PVC cross extend its life?
Helps slow the uv deterioration. That's why he is using grey electrical pvc instead of white water pvc.
They even make paint that is for that purpose.
A dome, but not geodesic. They have formulas for any size geodesic dome. Using even thin steel conduit you could have ended up with a much more rigid structure, bolted together at the junction points. I doubt it would have cost $250.
Yep, not geodesic.
Who are They?
@@fukkawi ...Desert Domes is one. www.desertdomes.com/domecalc.html
There are others. You go to their geodesic dome calculator, you enter the radius into the box and it will instantly tell you how many struts you will need and what sizes they need to be, center of bolt hole to center of bolt hole at the other end of the strut - so, if you're using steel conduit, you cut the struts maybe 2 inches longer than the measurements and drill the holes the distance apart indicated by the dome calculator.
u could also form up some rebar and pack into Cheaper white / painted sch40 pvc...
I also agree: A geodesic dome is specifically constructed from repetitive triangles or other polygons. But, there is some good thought into this project. A couple of thoughts: First of all, the bottom ring can be made from thin-walled 1" steel conduit and couplers that is bent into curves adequate to form into that form the desired diameter ring. A sheet metal shop would not charge much to run the straight lengths of tubing thru their bending equipment...and they would be able to calculate how much of a bend is needed to form the proper diameter circle. Second thought is that I agree that 2 x 6 way connectors would be a better idea at the top center point. With careful measuring, 3 x 4-way connectors could be cut apart with a jig-saw, such that they have 60 degree angles at the join end, and glued back together into 2 x 6-ways connectors. This were the concept of PVC glue is an advantage. Unlike most glued joints, which are weak point, pvc joints are as strong as the things glued together, because the glue literally fuses the joined parts together. However, to avoid all of this "fiddling", it is easy to find 6-way connectors online...specifically designed for actual geodesic dome construction. A quick search online will disclose some expensive ones (@$26), but also will disclose sources of more affordable "Sonostar" connectors for as little as $8.99 on Amazon.
Brilliant! New to your Channel... great stuff; and I’ll be sharing this diy geodesic greenhouse build with my sister; whose kids’ trampoline now has an exciting future!
Great idea! Thanks for sharing your ideas.
nice build - good center point solution. Spray the white Sched40 with a UV protection paint before putting it all together.
cheaper, and or pack em full of wet portland cement too for added strength / mass etc
If you can get the grey pvc in a four-inch size, cut off a piece about 3 to 4 inches long and then drill holes in the sides into which you can insert your pvc pipe. Drill small holes in the pvc pipe and use those to attach the pipes to the hub with metal zip ties. Look at Zip Tie Domes for an example.
They make a middle 5 cross tee .look under geodesic dome parts!!.great idea of using trampoline frame.
Might try using 90°elbows screwed & epoxy together to make a fitting on top ... Might work idk..
On another channel they took a 10 inch wide pvc pipe and used a hole drill to drill multiple holes around the circumference instead of using a T connector.
Love everything about it. Awsome.
You can use two wooden or steel circular plates and just screw the pvc pieces between the two at the peak for a sturdier connection of all the hoops, otherwise great design.
I didn’t retire at 40, but, did so at 42. Went into military at 18, stuck it out. Many called me lifer, many said they wished they had been with me, especially the ones I met thru basic training, went thru tech school, got assigned to the same bases, worked on the same jobs, all could have retired at the same time. Except one good friend, he was killed in a car accident. Pay heed enlistees, this could be you!
i priced 1” PVC yesterday… almost $20 a stick everywhere. That’s 500% inflation since you made this video. Wood and steel is close to the same. Unreal.
Way to go, just what I wanted. Downloading parts 1 & 2, thanks, enjoy! 👍🏼🙏🏼🌞
Brilliantly executed!
Excellent. I liked it. If I had the land space, I would build one based this model. Living in Florida, I'd probably use two rings of support like you suggested and anchor the base all the way around to the ground.
Right on!
As for the "cross" fittings, make one in the woodshop, the scrap plywood and dimensional lumber is also free and instead of having to buy 3 fittings you have one piece, and you could use it as an anchor point if it's heckin windy in your area.
Great idea!
Well executed design. I may have to try this.
I've got an unused trampoline in my back yard now I know what to do with it thank you so much
Have fun!
Nice concept, and the recycling of the tramp was a great idea too. Well produced video, thanks
Thank you very much!
Maybe a 3D printed cross-t? Or a sandwich of circles with a bolt through the middle, and the pipes attached radially, if that makes any sense.. so it would almost be like a basket construction upside-down.
For the cross-tee, find someone with a 3D printer, draw-up the six-ported cross T, and print your custom part!!, Also, sell it on e-bay on demand!!!!
Greenhouses are necessary where I live if you want to grow anything besides cold crops and berries. I didn't want to spend the money on a green house nor build a so-called 'cattle panel' or 'pvc' greenhouse. I wound up buying 15-16 pieces of 2"x2" and making a 4 ft tall by 4 foot deep by 8 ft wide oversized cold box that sits atop a 4x8 raised bed. The front is hinged at the top of the box to access the plants - and at the bottom of the back panel so the box can be tilted off of the bed box. My reasoning was simply "why is it necessary I be able to stand or go into the greenhouse? It only needs to be big enough for what I plant." It takes a bit to work out the dimensions to fit it all together. Clear poly is wrapped around and stapled to the 2x2's, the 5 pieces (4 sides and 1 top) are held together with decking screws through 1" diameter fender washers so as not to pull through the poly. I think the enclosure was about $30 (I used hinges I already had, and some hook and eye latches) and the 4x8 raised bed made from 2x12 ground contact lumber was about $60? It'll fit 4-5 tomato plants. Congrats on the early retirement. I retired from the aerospace industry at 43 in 1998. They got enough of my soul. The rest is mine. Best to you!
How about making a short video to show off your contraption?
@@mkeyx82 If I remember to next spring when it's reassembled. It can't stand up to the 45-50 mph wind gusts we get off the water during winter storms.
Nice cheap build. More to add to the build. Right.
You gave your mitre saw so take some grey pic, cut the proper angles and glue together making your spider. Just an idea. I know gluing tat stuff together is tough. It could be reinforced with a metal ring or a pvc reinforcement plate of sorts. Great idea you have there, Thanks Kindly! DaveyJO in Pa.
Fabulous video, clear presentation, very much appreciated. 🙂
Helpful hint, you can shape pvc by filling it up with hot play sand. Stick sand in the oven, seal one end of pipe temporarily, fill with hot sand, shape, let sand cool down, and voila.
I would have used the sections of galvanized steel sections that were the “legs” for the trampoline, which could be used to raise the height of the whole structure, ... in other words, just flipping the trampoline upside down would have worked much better to secure the size of the “dome” overall, ...
Great idea! A good way to.get a little extra headroom and growth area
@@live.life.simple. when the video showed you had cut the legs off, I went "oh what?😱!" You cut the legs off!!!!" How will you make it big enough inside to stand up??!!" 😵
Anyway there will always be several versions until you get to the fully executed idea!
It's all good👍
Fiberglass tent poles work great too. I drug out my tent, realized it was dry rotted so it was turned into a quick greenhouse. Shoved the poles into cinder blocks to keep the arch. Threw plastic over it and more cinder blocks to hold down plastic. Then threw some lacing rope over it to help hold down plastic and tied it to the tent stakes.
Then you have to deal with some other way to mount the electrical PVC. Maybe a hole saw to put holes in the bottom of the "legs" of the trampoline? Wouldn't be quite as easy to do.
@@live.life.simple. if the legs are used for height, how would this effect the amount of poly needed as you mentioned that 20ft x 25ft was originally needed
EXCELLENT!!! ILL POST PICS WHEN I AM FINISHED!!
That is a very neat idea , very cool
thank u , simple we can do it with family
A very creative idea for this greenhouse and built it cheaply. Great job. I subscribed.
What I would have done is make a hub for the center of the dome by gluing some 2x stock into a piece which I could drill 12 1" holes at 30° deep enough to receive the 1" pipes, but not all the way through, and set the pipes with deck screws. You could even get fancy and bevel 12 pieces at 30° compound angles, so the holes could be drilled at 90° to the lumber, but would flare at 30° from center. If you do this, you can install a vent at the center of the wooden frame, which is very useful for hot days.
Brother great project, but can I make a suggestion? I saw a guy use galvanized steel electric pipes. What he did was use a press to flatten the ends and put them together much like the way playground domes are. PVC will compact easier with the help of a heat gun and a vice grip. If you wanted to really streathen the structure more, you could drill the PVC pipe every foot or so and fill the pipe with expanding foam on the inside of the pipes. Youd be amazed at how hard it gets. Obviously this is done on the interior PVC and once built, as youre not going to be able to bend sh.t after you foam the PVC. Also if you can get the frequency of the dome small enough, you could buy old projection tvs fresnel lenses, to increase sunlight. Ideally youd want a tank of water inside also heated by the lenses. This will keep the enclosure warm at nite. Fish are dumb, but you could keep brine shrimp in the tank. Scoop up a net of brine and make brine burgers. Hope this helps and thanks for the vid.
New retiree subscriber here. Grew up country.
My dude, really nice idea with the trampoline base! :D
What you could have done for the top connector though is just put 4 cross-tees into the center cross-tee, that gives you 12 incoming :)
Thank you for the great IDEAS
A small piece 4" or "5 long piece of 6" pvc pipe with holes drilled in the side would make a great center piece. Screws could be added in the pole sections to keep them from coming apart.
Great video and ideas ... thank you!!!
100% agree. I'll do an update on the follow up video. Thanks for the suggestions, much appreciated!👌
Thank you so very much. I want to make this for my back yard. , greatfull for your ideas ..👍👍👍
