Here you can see the two epoxy formed ride pad bays.

Don't forget flotation, just in case.

[emoji16] Yes. Thank you. I just remembered I need to do that actually...

very nice.

Has anyone tried spray foam for flotation?

They use it in 1/1 boats. My local hardware store has low expansion, weatherproof spray foam I'm thinking about trying.

Here's a link to 1/4" teflon for epoxy forming carbon fiber...

Testing the expansion rate of the spray foam...

When I squeeze the epoxy cup, I feel no pressure on the sides. The pressure is escaping upwards.

A mod to the PVC pipe clamps. Zip tying polyurethane strips to them for grip so they don't slide around, and so they don't mark the birch plywood sheeting...

Yes, I epoxied the sponson tubes.

Even tho I know the expansion rate, I still overfilled the sponsons. Trust that the foam will fill them...

They must sit overnight. It takes that long to completely cure. I checked this out in the epoxy cup. Do not bump them, the foam will collapse and lose air bubbles.

This is the final expansion the next day...

The foam trims flush easily with a serrated knife...

Sammy,
Is that foam fairly light? Some of that stuff that I've seen is pretty dense and heavy.
