well.....
it's on it's side, I'm working on it that way for now, I can't lift it alone to flip it on it's top. I got it on one side, but, that's it.....If I get help I'll set it that way.
But:
I started "welding" holes and cracks with an old fashioned big soldering iron. It works pretty good and, I'm developing a technique that seems good:
it's a pointed tip, 4 flat sides to a point.
so, I take the tip and melt a "v" groove along the crack and, then, lay one of the flat sides on the plastic and move back, folding and melting the sides into the middle. It seems pretty solid.
I also tried a filling technique, for the larger holes:
using the soldering iron, I melted around the sides and pulled some of the edges in until I had a thin layer of material over the hole, at least mostly. Then, cut some bigger pieces and welded them in. But, to finish, I used a propane soldering torch, fanning the flame like brazing. it worked neat! it made a fair puddle, and, smoothed the surface and ran into the low spots. When it cools, it's nice and smooth. you can run it just like brazing, melting the surface and the other material follows the puddle, to a point....to much heat and it sags or runs.....

Anyway, now I'm just looking for more material for filling and may even try welding the edges of an extra sheet as a sort of "skid plate".........

any input would be welcome, since, I'm learning as I go.
