Rafter math

[Eliindigo]

Of course for the right rafter length you take difference in height of top of wall and compression ring (b²) + radius of circle minus half width of compressing ring (a²)= square root of c²?

[Bob Rowlands]

:head scratch: huh?

For the yurts rafter length lay out a full scale cross section of your yurt wall and ring on the floor. Lay rafter stock on your layout. Mark. Cut. There's your master rafter pattern. Less the rafters over the door.

Then add some length for the pitch?

[Bob Rowlands]

Rafters with pitch on them won't need any extra length. They'll stick in place.
