I've got it! It's some pieces of wood!

Whatta ya want, "the wood I had around behind my shed that had spiders under it and then I built a treehouse out of it" ???

It's some wood you had bundled up with your steel strapping machine, and then you unstrapped it and took a picture of it?

Ahhh, it's a map to the solution. A la The DaVinci Code.

I agree with Clodfobble. I think the tape should be the focus, and the 2x8 boards are distracting us.

Is it a layout for rafters?

Yeah, the marks have been irking me, too. It seems obvious enough they must be some sort of guide, but I can't really tell if they match the taper in the pieces of wood. That is the other thing to me; the second and third shots show splitting the boards into wedge shapes which form the arc visible in the first photo.

Well, BigV, are you making a really, really BigFan? :rolleyes:

He's building the boat that we will take to Ram Island!

A boat? Great!

Wait, uh, do we call him BigN(oah) now?

I think that the boards are straight. The arc is an optional illusion.

At first I thought you were finally getting around to showing how you built your kayak, and this was just before ripping strips to form the hull & deck, but you wouldn't be doing big long taper cuts like that. So I have no idea.

Are you making a big circular picnic table?

You could be right (I originally dismissed the appearance in picture #1 as such), but the second and third photos do show trapezoidal pieces. They also seem to indicate a spread in the border of the marks on the patio.

Maybe in post 124 that's true, but post 127 is clearly tapered.

Not optical illusion; optional illusion. It's not for everyone.

And is it an Ark or an arc?

With the exception of the split board, I think that they are all straight 2x8 or 2x10s.

Hmmm, I just don't know about this one. However, I do have a mental image of BigV wringing his hands while chuckling evilly as we all go nuts trying to figure it out. :lol:

Fish eye lense camera. Straight boards. Looks like fencing. They all split like that when you pull them off to replace them. Who knows.

A canopy for the deck

Hopelessly ancient ex-roof decking?
