Well, plan A failed utterly.
But, I was able to carve away the excess foam to get Trevor laying down properly.
So, on to plan B. Since the plastic had failed with plan A, I clearly needed something breathable. So, I rolled out some fabric, and pre-soaked it in water to help cure the foam. (Again, cures via moisture) However, I was aware this might create the same problem as at the edge of the foam where the foam itself made a vacuum seel and prevented proper sealing…I’d just have to deal with that as it come up.
It begun extremely well, with the foam rising to meet Trevor just as planned…
But, my fears proved valid on some larger areas where a cavity began to form. So, Plan C was instituted, cutting into the foam, and injecting water into the cavities. Now I just have several holes to cover up.
It’s not a perfect solution, but it’s workable. Now I need to figure out what to do about the fabric. Do I clay over the fabric to make a consistent surface on top, or do I just seal and paint it? Either way, I can get back to work on Trevor knowing where he is going to meet the ‘bed’. One big technical part left with his left hand and, um ‘modesty cloth’ for lack of a better term.
