It looks like it will be tough to fiberglass the inside of that box.
Well, we are hoping the fiber glassing will not be that hard. We have chamfered all the angles now and the ones we cannot we will use epoxy to make them radiuses. That will make it easier to glass. We will be using fiber glass tape which ours is about two inch strips of fiber glass to do all the edges and radiuses. Then we will be using fiber glass matting to do the flat areas. For the top we will get some fiber glass sheeting and cut and glue it to the top. Then use fiber glass tape for the edges.
We added two inches of foam all places but for the opening two sides (R5 an inch) Dow Blue board closed cell.
Four inches on the bottom. The refer has three inches on the ouside and can not be added to because of the space or lack of.
Sounds easy hugh?
We are getting some experiance as we are curently building a propna locker using this method.
We are addin width by the teak parts that supports lids by using foam. So we can have wider or more than one seal there.
We still have a couple of pieces to go with the foam. Then glue the rest of it in and then start epoxying to make radiuses. This is the refer on the spill over side. We have not started the freezer yet.
Also we still need to fill the small gaps with foam that was recomended at WM.
As for the seals:
One dock mate said he used door and window seals from Home Depot.
Another said he had his made from RHS Refrigeration Hardware Supply Corp
but said he would not have the same ones made again. These are the magnetic kind used on home refers.
It may be the HD ones as they come in different widths etc. Also Hinze our dock mate said when they get tired just rip them up and apply new ones as they are self-sticking.
Form more details and pics you can see it on the blog inch by inch as we go.
I guess I am over complicating this as usual.
