Moved the front gate bolt up a couple of cm to give a bit of clearance for opening & closing it. Next project should be a new gate but I'll wait & see how the barn door holds up through the winter.
Speaking whereof, got the first two vertical boards on. The one nearest the hinge was a right bastard (or, as was once said in Scotland and maybe still is, a tory) since it had to be profiled round a stone block at the bottom and a diagonal timber at the top, and then be bolted onto the horizontal through the hinge strap with enough room between board & wall to get two fingers in holding the nut. Aligning it by giving MrsT "up a cm" & "down a cm" directions for the hoist was fraught with marital land-mines. Second board was a doddle.
Found the impact driver worked a lot better if I started the holes with an auger and squirted oil in first. Too wobbly otherwise.
