Wood is good....

Framed out the back wall and started putting on the cladding - big mistake, the cladding is a bit wavy and is pulling the back frame out of line.
Strange how all the planks have a curve the same way so each plank pulls the frame a bit more curved up at each end.
Luckily I used screws - nice stainless steel ones, so took all but the plank end screws out and voila it all straightened up.
Looks Like I've got to put the frame up, screw it down and then plank it, which means working in a 300mm gap - 12" in old money. Could really do with a small boy with a screwdriver........

BTW Campervan man - it's a workshop not a shed, D2 would realise the difference.
