Following completion of cutting the roof, various parts that make up the cruck frame were stacked outside of the framing tent ready for uplift and movement to the woodland building site.
Various joints were employed to join the tie beams to the wall plates including cogged lap joints.
The cruck apexes have been cut to support the ridge
The same stack viewed from another angle reveals more joints.
Some of the tie beam ends employ 13th century style tace lap joints -
and the more common dovetail (double shoulder) lap joint.
Adjacent to the cruck pile were additional front, rear wall & roof components.
The cruck blades are anchored to the cruck wall posts with cruck spurs.
The full design, proportions, layout and working of the English Tying joint are now clear.
The cruck spurs employ both dovetails and taces to effect the joint with the wallplate.
The common rafters will be simply nailed at the apex over the ridge and at the foot on the wall plate.
The feet of the common rafters will then be fitted with sprocket pieces to create eaves.
The purlins like the wall plates are made in 3 parts which are scarf jointed together using a variety of joint styles
The wall plates overhang the main corner posts and are scalloped.
