Not only rafters are made of logs, but also puffs, and for puffs that compensate for spacer loads, you must select the highest quality wood material. The prepared logs are faceted in length.
The maximum length of standard roundwood is 6.5 m. For this reason, in order to overlap large spans, the inhaling should be made of two or three logs connected in length.
At rafter legs, struts and racks made of logs, it is required to finish the ends and cut the heels using the templates prepared in advance.
