Second Gluing

After the first gluing. I'm much more liberal with the epoxy and am trying the flatter concrete in the driveway. Luckily I live in sunny California so the conditions in the driveway are almost exactly the same as in the garage. Here's a nice high-res timelapse. I've figured out that I can do the high-res videos quite well however it was pretty dark so the quality is not super great.

You'll see that I made a small mistake in cutting the holes which required a slight adjustment but otherwise I think it went well and I expect to find it solidly glued in the morning. The flatter surface helped a lot and the weights seemed much less necessary to keep gaps from forming.

Here's the result in the morning.

With weights still on it

Weights removed

There's one slight caviat that with the extra epoxy some slipped down one of the cracks and I appear to have glued it to the ground....

I couldn't force it manually without risking breaking the whole piece. As I could only get leverage from the edges.  So I slid a string underneath and sawed away, until the string broke. Then I slide some cardboard underneath both sides of the glue by bending upward and when I let it back down the weight of the rest of the foam pried upward such that a manual pull at the edge was enough.

Here's the results:

Remaining dead string and chunks of foam left. Note the sawed foam at the bottom left vs the chunks at the top right from prying.

There was a little cosmetic damage and one hole I'll try to patch. 

But the resultant hull is pretty awesome.

The resultant hull. 

The bike gives a good sense of scale.  And for reference I can lift the whole thing with a single hand assuming I can balance it. I moved it into the garage single handedly despite it being 12 feet long and 6 feet wide.
