Watchouts!Building your dome should be great fun and the last thingwe want is for people to hurt themselves. Here are a fewthings to watch out for:123Hubs are hingesSockets can pinchFalling sticks!!!Hold sticks awayfrom the hubsKeep fingertips awayfrom socketsTip:Wearing glovesminimises the risk.Not a climbing frameStay on the outsideas you buildTip:If a stick pops-outjust pop it back in!Don’t suspend heavy objectsThe benefi ts that hubs bring to the build and adaptationof domes comes at the cost of ultimate strength.Domes built with hubs are still satisfyingly sturdy structureswhich are more than strong enough for their intended uses;eg fruit cages, garden rooms, chicken runs etc.

The buildBefore you begin – separate pilesx6x35x20x30 Read out the descriptions and checkprogress against the illustrations.SHORTSLONGS5-ways6-waysIt’s easy to mistake SHORTS for LONGS and 5-ways for 6-ways!StepYou need5-wayhub1Thenx5Description (read this out to someone helping x10x108x10 Start with a 5-way hub in the middle and connect five SHORTS into it.– hubs should always face up and sticks always connect in from below. Snap a 6-way hub onto the end of each SHORT. Place five LONGS around the outside and connect theminto the 6-way hubs. Lift the centre 5-way hub by its sticks to make the final connection. Connect a pair of LONGS into the left and right free socketsof the 6-way hubs (keep the middle socket free). Use 6-way hubs to connect the LONGS together to create triangles. Connect a SHORT into the remaining free socket of each 6-way hub. Snap a 5-way hub onto the end of each SHORT. Place ten SHORTS in a ring around the structure so far. Work your way around the ring, connecting the sticks one at a time– when you can’t make a connection lift the hub above.x10x10LONGIt should look like this! Connect two SHORTS into the 5-way hubs and two LONGSinto the 6-way hubs. Use ten 6-way hubs to connect SHORTS and LONGStogether into triangles.– use sockets that are next to each other on the hubs. Place ten LONGS in a ring around the outside. Work your way around the ring, connecting the sticks one at a time– use sockets either side of those already populated.– when you can’t make a connection lift the hub above.DOME DONE!Check out theCompleting your domesection for next steps.

oropen out forbuild instructionsCompleting your domeOnce you’ve built your dome, move it into its final position before clamping-upthe hubs. Two people should be able to drag your dome to another position.We’d recommend four people or more if you are lifting the dome.!anchor your domeWhichever base approach you use ensurethat the dome and any cover is securelyanchored to the ground. Wind can placean enormous force on sheet covers andeven netting.1. Choose base approaCh orLow bASERAiSEd bASEEven a small foot can help to protect thebottom ring of sticks from dampA greater sense of space andeasy access for smaller domesorwood screw included in the kit oruse hub screw with a threaded insertwood screws includedin the kitStanding upLying downSmall feetPostsScrew two ball connectors 3mm apartonto your base. You could also use twoball connectors in a hub as a template.Test your first attempt in a hub tocheck that the position is ok.The hub sits horizontally and a screw throughthe centre of the hub can fix it to the base.It’s also possible to use a hub screw if youembed an M6 threaded insert in your base.These can simply be blocks of wood.Drill with holes so you can stake themto the ground. You can also add eyeletsor hooks for attaching covers.Build your dome first and mark the positionof the hubs. Then make holes with a littlewiggle room so you can adjust the positionof posts when you put the dome on top.Tip:If proving tricky, slightly looseningone ball connector helps.?!Temporary useIt is possible to simply rest your dome onthe ground using the lying down approach.Stake through the centre of hubs or stakedown the bottom ring of sticks. If the domeis on a hard surface use metal weights orsandbags to secure the base in position.not too wideIf the hub is lying down make sure the widthof the feet or posts is 70mm (2¾”) or less tobe sure that they don’t clash with the sticks.2. CheCk alignmenT3. Clamp-up The hubsHubs will want to find the right alignmentbut after a build some might be out of position.Once finger-tight use the allen keyto clamp firmly.Get the angles in the basering as consistent as youcan before fixing in place.Correct by pullingsticks towards theoutside of the dome.Pushing inwardscan pop sticksout of the hubs!!Tap sticks leftand right tocorrect rotationalmisalignment.Taking down your dome!Un-clamp all hubsbefore taking thedome down.One person supports the weightof the dome by holding the centralpentagon as shown (blue).A second person removes the shortsof the central pentagon (red).The next sticks to be disconnectedcan be rested on the ground to supportthe dome as you dismantle it.Continue the process until you’re backto a collection of hubs and sticks!Un-clamp allhubs beforemoving a dome.Moving a domewhilst the hubsare clamped-upwill damage thehubs and ballconnectors!
