Recently raised

This green oak timber frame went up at the end of last week, on one of those days when it poured down everywhere else, but somehow missed Falmouth. The client is updating and re-fitting this house, and wanted a fully glazed extension to make the most of the views out towards Carrick Roads.

The 6m tie beams in these king-post trusses weigh over 250 kgs, with a complete truss weighing over 550 kgs, so we hired this neat little spider crane from fellow framer Stefan Roux. When all folded away, it's no more than 650mm wide, so can be driven on its caterpillar tracks through doors and gate to help raise frames in the most awkward spaces.

Doesn't seem that long ago that we were cutting this in the workshop, laying up the frames in the horizontal, and scribing in each joint with a plumb bob to get a perfect fit regardless of the nature of the timber. All our green oak frames are laid up like this...its the only way of ensuring really good tight joinery and the massive structural integrity that goes with it, as well as making raising the frame a simple, fool-proof process.
