Here’s the current thread- viewtopic.php?f=53&t=71911
I started out planning on a foamie build, which grew too large, so a little rework and a new canned ham standee began. It is wood framed, 1.5” thick, sheeted with the dirt cheap 2.7mm Luaun plywood, then canvassed.
This is the first update in a while, since completing the PMF and getting the exterior electrical wrapped up. It’s been a crazy busy fall so far.
I sprayed urethane expanding foam on the entire interior as well as under the floor and fender wells. The underside also got fully undercoated! Sorry, I didn’t get pics of that.
The foam is very rigid and bonds crazy well, so it adds a ton of stiffness and structure to the thin plywood skin. It is now rock solid, and very well insulated to boot!
Today I scarfed the foam back flush with the furring with a wire wheel on a grinder. This is quite possibly the worst job ever! The foam dust reacts aggressively to static charge, it floats in your eyes, and you can’t get it out. It sticks to everything, and is a huge pain to clean up.
Once completed and cleaned up, I was able to get a little lining started. I wasn’t able to get the plywood to bend enough to shape to the interior side of the curve, like I did on the outside. I wound up having to do it in segments, but it’s still going well.
