The sub-fossilised trunk was discovered in the fens of Ely in Cambridgeshire. It is 44ft long (13.4m) with no taper and could be only one-quarter of the original tree.

This week the trunk was to be saw milled into full length planks on site on a 50ft Logosol saw mill shipped in for the project. The planks will be kiln dried in a bespoke 15m kiln at the Building Crafts College in East London, which are expected to be processed until April 2013.

The Diamond Jubilee Fenland Black Oak Project was instigated by bog oak specialists and cabinet maker Adamson and Low with help from the Worshipful Company of Carpenters. Sponsors providing funds or services so far include Logosol, Coillte, Insitu Design, BCC and the Queen Elizabeth Scholarship Trust.

A 44ft-long table will be made for public display by the BCC’s fine woodworking students.
