I have just posted this in another area but thought as it may well be thrifty I will post it again here as I need your input Guys.
Idea that just might work:
I have been thinking about the floor in this picture
Obviously the foam is used for insulation and for weight saving. In this case he is covering the floor with 1/8" ply.
Its a great floor but took 27 hours for finish which compared to Eagle and GPW they almost completed a Foamie body in that time.
I then started thinking, once its skinned its just a very thin box with partitions inside. Each partition is filled with a cut piece of foam. However he spent ages glueing it all together and filling all the gaps so it does not move. Each stage had to be clamped until dry.
My idea is to do the same wooden grid and fit the top and bottom but without any foam inside. I will then inject spray foam (Cavity wall insulation) through small holes in the underfloor to fill the voids. The holes will be simple to fill.
Anyone who has used spray foam will be aware it sticks to almost everything, and if there is an area you dont want it to stick to simply cover it with cling film.
Spray foam is available in aerosol cans so no mixing, very little waste and no need for a trailer to fetch it. Its available at every DIY store and even on ebay.
Once its injected through the holes it expands and would fill the void in the same way as cut foam but with one huge advantage.
One of the biggest problems with pink and blue foam is a suitable glue and having to clamp it together while it dries. TB2 does not work where it cant get to the air and GG is a bit messy and foams so has to be cleaned up after the clamps come off, and epoxy has to be mixed and weighted down.
pods8 did this
Once you have made your floor box (or wall if you want) you would inject it and as the spray foam expands it seals all the holes and at the same time sticks like "S**t to a blanket" to glue all the parts together in every corner.
No filling, No clamping, no paving slabs, no leaving it in the same place until dry, you could inject it and lift it up and put it out of the way and it will dry in an hour.
Can anyone see a problem with this and will it still be a foamie?
