1V Shade Structure
Above you can see the completed 1V shade structure that fits over the dome
deck. Here are instructions for how to make it.
- You'll obviously need to make the struts for the 1v dome before you
can assemble them. How big should these struts be? You actually have a
lot more flexibility than you might think because of the way that a 1v dome
works. The "Wall Struts" (the ones that connect the dome deck to the roof
of the 1v shade structure) must all be the same length, but, you can pick
your own length (technically so as long as they are more than half the length
of the dome deck pentagon struts -- the long struts in your dome). Really,
you might want to use some fairly long wall struts, because it raises the
The 1v roof pentagon struts could also be longer or shorter, depending
on your preference, but, it probably doesn't make sense for them to be
shorter than the dome deck pentagon struts. If they were shorter, the
shade structure would have a smaller roof than the base, and the walls
would lean inwards. If they are larger than the dome deck pentagon struts
then the roof will be bigger than the deck, which might not be too bad.
Then the roof will cast a bigger shadow and be a better shade cover. But,
of course, the walls would lean outward. It might mislead someone into
thinking the wooden deck is larger than it really is and they might step
off the deck! I made my top pentagon the same size as the dome deck
pentagon struts so that the walls are vertical.
The 1v roof radial struts need to be long enough so that the roof is
higher than the roof pentagon. It needs to be enough higher so that the
structure is rigid. For example, the center of the roof should be at least
1 foot higher than the roof pentagon struts. In a regular 1v, the center
of the roof is higher than perhaps you want for the shade structure. A
high roof is more likely to catch the wind.
In the end, I just took the conduit left over after cutting the roof pentagon
struts and flattened the ends and called those the radial roof struts. That
made for a lower roof than I would have had if the radial roof struts were
the same length as the roof pentagon struts, and it had the advantage of
eliminating all waste for those struts.
- You should already have attached angle brackets to the top of the
risers. If not, attach them now. The 1v wall struts will attach to these
- Bend the ends of all the struts that are part of the 1v shade dome.
The ends should be bent to about 20 degrees or so.
- Attach two wall struts together with a 2" carriage bolt and add a nut to
keep them from coming apart. Do the same
four more times so you have five pairs.
- Attach the free end of one strut from one pair to one of the angle
brackets at the top of a riser using a 1" carriage bolt. Add a nut to
keep it from coming loose.
- Attach the free end of the other strut to the angle bracket on an
adjacent riser. Before adding a nut, add a free end from another
paired of wall struts. Then add the nut. Repeat this step for each
pair of wall struts until all the wall struts are attached to the
- Attach a dome roof pentagon strut between the top of each pair of wall
struts. Repeat until the doom roof pentagon is complete.
- Attach a radial roof strut to a dome roof vertex.
- Attach a another radial roof strut to a dome roof vertex and attach it
to the other radial roof strut(s) you have already just attached.
Repeat until all the radial dome struts are attached. Violla! The 1v
shade dome is done!
