hi alec,

 

the outer gable rafters (the outer-side of the ladder), are housed over the wall plates and have a birdsmouth. the principal rafters are morticed into the tie beams, and the common rafters (3x7"s)(and including the larger 4x7"s for the velux's - the 12 i bought) are all seat cut onto raising plates (that sit over the top of the loft floor joists and above the wall plates), lap jointed at the peak, and nailed) they got 9 nails a piece into the foot. wasn't sure just how well that would hold until i tried to rip one out that was slightly proud of the line, to be rehoused, hellishly hard to get out, so no worries about them sliding.

(had seen the same rafter housing situation on a 500 year old house i'd done roof repairs to outside of colchester 5 or 6 years ago)

 

(will pm you a close up)
