So, finally got back to the big project - OB19. Here's the arrival from storage - it's hard to imagine this is going to become something like what I'm imagining:

As you can see, lifting all the ply in and out of the truck make's you thirsty!
So, then it was on to building the strongback - I used 2x6x18' boards, with 40" clear between. This is a little wider than what the plans call for, we shall see if that's any issue.

On the strongback, I'm using 2x4s for verticals, and put plywood triangles in all 90 deg corners, to lock it in against deforming like a rhomboid. So far, so good.
