In the location in which you intend to place your dome, clear the ground by removing all grass from an area that is 12' in diameter.
1) Start by measuring and cutting 30 pieces of wood that are 42" in length. These are your "A" pieces. It would be good to mark them with the letter A...
After cutting the wood, use paintbrushes to coat it with the waterproof sealant. Allow it to sit overnight or until dry.
When you are finished, you will have 10 4-way connectors, 6 5-way connectors, and 9 6-way connectors.4-Way Connectors1) Begin by cutting ten strips th...
1) Begin by cutting thirty strips that have seven holes each. 2) Once you have all of these strips cut, use a vise to bend the pieces after the first...
1) For the 6-way connectors you will need to cut twenty-seven strips that have thirteen holes each. 2) Once you have all of the strips cut, you need ...
5-way connectorUsing your drill with a screwdriver attachment, fasten one arm of a 5-way connector to a 42" (A) piece of wood using two screws (with t...
Next you will attach two 4-way connectors to the assembled 5-way connectors and A pieces. Put a washer around the screw (two screws go in each leg), t...
Next you will attach two 6-way connectors. Put a washer around the screw (two screws go on each leg) then attach one arm of one 6-way connector to the...

Put one socket wrench on the nut side and one socket wrench on the bolt and tighten up all of the connectors on the dome.
Since there are variables that affect the exact dimensions of your completed dome, making the door is a field-engineering task. Measure a piece of wo...
After you mark the piece of wood, cut it at an angle so that it fits the pentagon flush against the top piece of wood. Attach the cut piece to the 4-w...
Next, measure another piece of wood to create the top part of the door. To do this, hold a piece of wood at right angles to the tops of your two paral...
Next, measure a piece of wood that goes from the 6-way connector at the side of the pentagon to the piece of wood that makes one side of the door (see...

Cut out a large sheet of plastic, about 6 to 7 feet long. Cover a section of the dome with the plastic. Start from the bottom and work your way up. S...
Pull the plastic tight over one triangular section of the dome. Staple just enough to attach the plastic to the wood on each leg of the triangle. The...
Repeat the process until the dome is covered. You will need to put a ladder inside the dome to staple the plastic onto some of the top parts (see phot...
You'll most likely need a ladder inside the dome for this step. Place the ladder on the ground under the top of the dome. Cut along one leg of any tri...
