Rafters for a concave conical roof
Before moving any further with the round gazebo that I'm currently working on I decided that I should start messing around with the roof. Mostly to check if the outer diameter of 24 studs will be sufficient for the roof design that was planning for this thing. It will be a little more steeper than I was originally planning but it looks it will fit :)
The concept here is the same as in the dome design: 8 main rafters with studs facing outwards provide structure support while the other 8 rafters with studs facing inwards are connected alternately by the mixel ball joints the main support rafters and have bumpers at the top (the dark bluish grey 1x1 technic liftarms). The latter rafters not only provide the rigidity for the whole roof but also provide connection points for the panels.
Yesterday I posted some images of almost the same thing but when I was writing the description it struck me that the central part that connects all the rafters was too big. The lengths of the rafters are 7 studs for the lower part and 6 studs for the upper part connected at 22,5* degrees which for both gives 7,25 studs in horizontal distance that they occupy. This means that rafters from the opposing sides occupy 14,5 studs total which leaves us with 6,5 studs for the centre. This was the tricky part because we need to hide 2mm offset at each side and be able to connect all the rafters. The solution was to angle 1x1 plates with clips at the a funky angle (a little more than 28 degrees from what I have calculated) so that they would occupy 6,5 studs.
Now it's time to figure out the panels :)
