FInishing bottom reinforcement

Thanks to some help from Jenny today we've more or less finished sealing up the bottom of the hovercraft.

There's two small joints that I'd like to fiberglass over. However, my epoxy level reached a critically low level such that the pump for the resin started sucking air. So I had to use my estimate for the right ratio to mix the epoxy.

We started off the day by sanding down a the previous epoxy work. And we got the hovercraft balanced back on it's other side. With the skirt attachment point it's actually semi-balanced not quite on it's side. So I tied it in place to the rafters.

The hovercraft propped on it's starboard side.Ready for work.

We cut a few more strips. I switched back to using scissors from the razor blade. It cuts with less pulling stress, and allows me to follow the weave better. This leaves the edges much more square with less dangling fibers.

Marking the fiberglass with a pen prior to cutting for better weave cutting.
We finished up the side with the last of the epoxy. Here's the full timelapse.


One oddity when flipping the vehicle was that I had a little bit of oil leak from the front engine on the port side. But on the starboard side fuel started coming out of the primer pump. And there was a bit of a leak from the thrust engine but turning off the fuel cutoff helped that a lot. ;-)

And here's the results as it's drying. I found just enough epoxy to seal up the small side joint too.

The glued edges, still curing.
