First plywood gluing

So now that we have the core of the hull formed out of foam. The next step is to attach plywood to the exterior. It has two major functions. The first is to be a tensile element making the whole hull an effective box beam.  Secondly it also protects the foam from impacts and denting.

Here's another timelapse of the process.



Thanks to Michael G for the help. And Wim provided some good comments at the end.

To cut the plywood the cordless Makita circular saw was

Weighted plywood for curing epoxy. 

You'll note that the weighting is much denser. This is due to the flexibility of the plywood. I will need to inspect more closely, however even with this density I believe there are still pockets where the plywood is separated from the foam.

Also an issue we identifed was that working in the full sun the epoxy seemed to almost dry out on the foam before we flipped the wood on top. Even though we were well within the expected 30 minute setup time. We rewetted the area but I'll need to do some inspection, and I will avoid full sun in the future.

In the timelapse you can see the fan ducts for the lift fan was placed on the hull as we discussed mounting options for the front motor. This needs to be addressed at this point so that we make sure to cut the plywood for the front end correctly.

Here it is parked inside:

Even with 3 layers and the plywood. It's still trivially liftable by two people.
