Foamies,
I am new to this and working on design for my first foamie. May start a build journal after I get a few design challenges worked out.
My plan is to build a 6' X 11'6" Winter Warrior that lifts up to standing height in back. Walls will be 2" foam covered with canvas drop cloth/glue. Ceiling would be kerfed 2". The back half where the hatch sits will be 1" thick with a 1" thick hatch that will "nest" in the opening created where the 2" meets the 1", if that makes any sense. Does that seem workable?
Planning a raised bed that sits lengthwise and has a 10" walkway on either side of the bed, with the bottom half of the bed pop up to create a dinette with benches on either side of a 2X3 table. That part is built.
Question about the walls - has anyone ever cut a 1" notch (i.e., a rabbit cut) in the 2" at the bottom so that a 1" thickness of the wall overhangs the floor and the steel frame of the trailer? Walls would then be glued to the edge of the floor and 1" of floor itself, thus covering the plywood edges of the sandwich floor and the trailer frame).
Could really use some feedback/ideas as I have never seen any of the trailers discussed in the foamie threads.

I have used a hot wire to cut grooves in the foam for bulkheads and shelf support. Could be easy to cut something similar for the floor to slide into.

When you do you 1" and 1" make sure you allow for thickness of paint and canvas! Sounds good on paper, but when in application, not! I would probably allow at least 1/4" for allowance. Unless you do not plan on canvasing between the two pieces.

Ok considering tearing dowm the duct tape PVC foamy the the frame again :? and building a standy (if I can't find an old standy to rebuild)
Can't find an answer in the questions about foam is there a major upside to going with 2" rather than 1.5" ?

I don't know, may be windows, fittings that match 2" better, more ridig structure overall, but is it really necessary? I am building with 1.5".

I'm building hybrid with 1.5 foam and 5mm inner panels. I'm happy with it and wouldn't change.

If I build another it will be more traditional style construction; slide in rear entry slouchy or standie with 5mm inner and outer skins. Maybe even 3/4 thk foam instead of 1.5, but this is kind of an apples to oranges comparison. Just another data point, for what it is worth.

You'll build another one kc, you'll be lost when this is finished.
I'm already tossing ideas around for a more simple traditional Kenskill for a trailer I've got sitting around...a bit like sir Edmond Hillary s famous qoute..just because it's there

Maybe. I've got my eye on some other woodwork projects too, now that I can no longer claim to be a novice woodworker. Those are much smaller in scope, tho, so maybe. :thinking:

I have to fully agree with KC and so many others. Less than 25% into my build and I had already begun thinking of "the next one". Yes this is a hybrid, but it is mostly wood. The next one will be almost all foam, I thinks I do!

These Teardrops and Tiny Trailers...yes they are the heroin of do it yourselfers. Here old feller, try this little teardrop...like it, eh? Well, now you must build another, and another and another. You must try out all kinds of weird ideas and they will probably work too! And get your spouse involved too, nothing says "Junkie" like a family affair!

It is TEMPTING to keep building little trailers , especially Foamies' which are so EASY and Affordable ... Not to mention they can carry more cargo than their Heavy wooden brothers ... And here, are especially useful should we have to leave town during Hurricane Season. :frightened:
There’s no place like Foam !
