More rarely they were made of masonry.
Framing cone shaped roof.
In this case the cone roof was surrounded by a protective wall a parapet or a battlement.
There are 2 kindsof conical roof molds.
The issue is not the 12 12 pitch pentagonal timberframe built with 6x12s but the lofting of the over framing to create an insulated conical shape that must fair into a 12x12 common roof constructed of 6x12 timberframe rafters.
To create maximum space under the roof the section near the walls rises steeply.
Hip roofs can also be linked up to fit l shaped buildings or combined with gabled roofs such as on this house.
Small conical roofs such as are frequently used on small circular towers are best framed as shown in fig.
The main difference between these two molds is the texture of the shingles.
Such conical roofs were usually constructed using a timber framed support structure covered with slate.
It wouldn t have a diameter of 8 5 untill about 6 10 above his top plate.
The plate should be cut out of wide planks and always made of two thickness put together so as to break joint.
Both of these molds contain the same basic block shapes.
Either of these molds can be used to make conical roofs for 3 4 6 and 8 diameter towers.
Oddly enough the budget must be met.
When well spiked together they thus form a continuous ring to resist the outward thrust of the rafters.
