Post Felling, Hewing & Japanese hand saw conversion

Axel Weller and Jack Wheeler teamed up to convert timbers for a traditional building conservation project in Suffolk that featured in Woodland Heritage 2014 (pp 32-35)

Oak trees were felled, hewed and hand sawn on the spot.

Once bucked to length the oak butt was scored and juggled to produce a large rough beam ready for hewing.

Image

The rough beam was then finished hewed to size and finish using a side axe.

Image

Chalk lines were then snapped onto the hewn beam to mark it for saw conversion using a Japanese Maebiki oga (saw).

Image

This is a hand powered saw process that requires sawing first from one side -

- and then the other to ensure that the saw follows the snapped chalk line.

Image

The finished sawn slabs are then ready for use in timber-framing.

Image

This hand sawing process would be ideal for producing cruck blades in the woodland where it would be easy to follow a curved line. This process would produce a very distinctive saw kerf pattern on finished sawn surfaces resembling a herringbone pattern.

The closest modern version of this saw that I have been able to find is the Kobiki Nokigiri and Temagari saws available mail order from Dieter Schmid - Fine Tools in Germany. An article by Adrian Leaman on the use of these saws appeared in the April 2014 edition of the The Bodgers Gazette.
