| =Construction of the pipe cleaner connectors= | | == Constsruction of mini dome == |
| [[File:Pipe Cleaner Connector 1.jpg|200x300px]] Start with two pipe cleaners, crossed in the middle.
| |
|
| |
|
| [[File:Pipe Cleaner Connector 2.jpg|200x300px]] Fold them across each other. For a 4-way connector (blue hubs in the construction diagrams), do this again and stop here. | | All minidome related info has been moved [[Minidome|here]] |
|
| |
|
| [[File:Pipe Cleaner Connector 3.jpg|200x300px]] Add a third pipe cleaner across the fold to form a crude hexagonal arrangement. For a 5-way connector, offset the lengths so one is shorter than the others.
| | == Construction of midi dome == |
|
| |
|
| [[File:Pipe Cleaner Connector 4.jpg|200x300px]] Counting from the top clockwise, fold the first(2 o'clock) and fifth(10 o'clock) spokes around the sixth (12 o'clock). | | All mididome related info has been moved [[Mididome|here]] |
|
| |
|
| [[File:Pipe Cleaner Connector 5.jpg|200x300px]] Do the same for the the second(4 o'clock) and fourth(7 o'clock) spokes around the fourth (6 o'clock).
| | == Construction of Maxi (9m) dome == |
|
| |
|
| [[File:Pipe Cleaner Connector 6.jpg|200x300px]] Rotate the entire structure clockwise by one spoke. | | All maxidome related info has been moved [[Maxidome|here]] |
|
| |
|
| [[File:Pipe Cleaner Connector 7.jpg|200x300px]] As above, fold the first(2 o'clock) and fifth(10 o'clock) spokes around the sixth (12 o'clock) in the opposite direction to before. | | [[Category:Tent Designs]] |
| | |
| [[File:Pipe Cleaner Connector 8.jpg|200x300px]] Finally, fold the second(4 o'clock) and fourth(7 o'clock) spokes around the fourth (6 o'clock) in reverse again to produce a 6-way connector (white hubs). For a 5-way connector (red hubs), loop the short end around the core and trim it short.

| =Strut construction=
| |
| Cut:
| |
| * 50x 15.5cm tubes (A, purple in construction diagrams)
| |
| * 40x 15cm tubes (B, red)
| |
| * 30x 13cm tubes (C, blue)
| |
| | |
| =Dome construction=
| |
| -Things to remember:-
| |
| * The dome only consists of two types of triangle - AAB and BCC. If you ever construct any that don't match these, something has gone wrong.
| |
| | |
| [[File:Dome Construction 1.jpg|200x300px]] Start with a 5-way connector and put 5 C tubes around it. Tip these with 6-way connectors, and connect them with 5 B's to form five BCC triangles.
| |
| | |
| [[File:Dome Construction 2.jpg|200x300px]] Add two A tubes to each of the outlying 6-ways leaving the last connection free. Connect these at the ends into five AAB triangles with more 6-way connectors.
| |
| | |
| [[File:Dome Construction 3.jpg|200x300px]] Fill up that last space with B tubes, and end those with 6-way connectors. Join all the outlying 6-way connectors up with more A tubes to make 10 more AAB triangles.
| |
| | |
| [[File:Dome Construction 4.jpg|200x300px]] Any 6-way with just A pipes to it, add two more A pipes. Any others, put two B pipes around it leaving the centre free.
| |
| | |
| [[File:Dome Construction 5.jpg|200x300px]] Make 5 more 5-way connectors with all the remaining C-tubes and put one joining to the remaining spaces where the B-tubes join. Then use more 6-way connectors to join up the next outer pair and form 10 more AAB and 10 BCC triangles.
| |
| | |
| [[File:Dome Construction 6.jpg|200x300px]] Connect the new 6-way connectors from above with a B-pipe. This will lift the dome a lot.
| |
| | |
| [[File:Dome Construction 7.jpg|200x300px]] Fill up the remaining spaces on the 6-way connectors with only A's and B's by making sure that a B-pipe is never next to another B-pipe.
| |
| | |
| [[File:Dome Construction 8.jpg|200x300px]] Join the ends of the new B's and C's with 4-way connectors, and A's and A's with 4-way connectors, forming 5 AAB and 10 BCC trinalges.
| |
| | |
| [[File:Dome Construction 9.jpg|200x300px]] Join the remaining spaces up, connecting two BCC triangles with a B-pipe, and everything else with an A-pipe in an A-A-B pattern as you go around. Initially this will put a lot of stress on the freskly made joints, so on large scale make sure you have someone to help lift the dome with you as you complete.

| | |
| =Covering=
| |
| I have prototyped a theoretical covering for the above structure consisting of hexagons and pentagons of 18cm side length. There seems to be enough slack with this ~20% extra space to allow for the centre dimpling of each polygon. On large scale this covering will need tying down somehow - I'd recommend constructing tiedowns on the triangular face joints. This ought to allow sufficient strengthening, and is possible to tie on if the above construction method is used, by constructing the whole thing underneath the covering.

| = Todo =
| |
| | |
| == Construction ==
| |
| * Enumerate required tools
| |
| * Acquire missing tools needed
| |
| * Settle on size
| |
| * Settle on tube diameter
| |
| * Settle on linkage design
| |
| * Determine total length of tubing required
| |
| * Find supply of PVC tubing
| |
| * Purchase materials
| |
| * Cut tubes to required lengths
| |
| * Build linkage
| |
| * Create assembly plan
| |
| * Assemble in back yard
| |
| | |
| == Covering ==
| |
| * <s>Request a sample of hermetix from supplier</s>
| |
| * Validate Hermetix as viable covering candidate.
| |
| * Decide on covering material
| |
| * Determine how many hexagons and pentagons are needed
| |
| * Calculate appropriate sizes for hex and pents.
| |
| * Find supply of covering material
| |
| * Extract required shapes from material
| |
| * Decide on how to bind the shapes together
| |
| * Create cool showoffy idiopolis artsy design for covering
| |
| | |
| A rough estimate based on a 10m dia dome, yields 256m2 of covering
| |
| A request for a 1m2 sample has been sent out on 22-4
| |
| | |
| == Transport ==
| |
| * Determine dimensions of a case or cases in which the dome can be transported
| |
| * Create a design for said case(s)
| |
| * Build case(s)
| |
| * Find someone with a van/trailer/bus to transport the dome to germany
| |
| | |
| = Ideas =
| |
| * Connector construction: [[http://www.grit.com/~/media/Images/GRT/Editorial/Articles/Magazine%20Articles/2014/01-01/Zip%20Tie%20Dome%20Chicken%20Coop%20Doubles%20as%20Greenhouse/Special-PVC-Hub%20jpg.jpg]]
| |
| | |
| * Using steel CV pipe rather than PVC (heavier, but cheaper and stronger)
| |
| * Using Hermetix as cover. E137,60 for a 50m * 8m roll
