Gratz Industries HQ: Walk the Plank

>> Monday, September 17, 2007

Time to walk the (aluminum) plank, me hearties!

The sheathing on the roof has begun.

The first layer got put up today on two of the four sides of the roof.

Here you can see the edging on the rafters.

And a bit further out, where you can see they've already added the house wrap to the sheathing up there.

Then late this afternoon two new things got delivered: the roof insulation . . .

. . . and the green metal roofing . . .

. . . in various sizes. It all looks great, although . . .

. . . I'm not really sure what this is, or what it means. Is it a Blair Witch thing?

Looks like a makeshift plumb line and bob to me. By crossing the nails perpendicular to each other, the plumb line makes a bisection of the crossed nails giving a good idea as to the degree that the roof is plumb.

“A plumb-bob or a plummet is a weight with a pointed tip on the bottom that is suspended from a string and used as a vertical reference line.

This instrument has been used since the time of the ancient Egyptians by bricklayers, masons, and carpenters to ensure that their constructions are "plumb", or perfectly upright. It may also be used in surveying to sight a point on the ground that is not readily visible.”
