Maximal branch diameter:
| Soft fresh wood (spruce, pine tree): | 80 mm |
| Hard fresh wood (oak, hornbeam) | 65 mm |
| Hard dry wood (oak, hornbeam) | 50 mm |
| Block (spruce) | 60 x 60 mm |
| Board (spruce)) | 190 x 20 mm |
The length of the small logs is between 6 – 13 cm. The average length is 9 cm for the series “70”. The length depends on the diameter of branches and whether wood is dry o fresh. The logs from small diameter and fresh wood are longer and from larger diameter and dry wood are shorter.
