OK, I could not stand doing nothing today, so I molded early, not waiting the full cure time for the mold. It works, but may cost some long term durability.
The top left two are the original cork boddied jigs, sanded to shape, sealed with wood sealer, coated with clear nail polish so they release better when molded.
The ones below them are made with Alumifoam. That stuff is super tough. It has a density of about .47 g/cc. Two have hooks but two will be for cutting and inserting other hooks. It is rated at 20 pounds per cubic foot.
The row to the right is made with Alumilite 610 foam. It has a density of about .24 g/cc, or about half that of Alumifoam. My testing of this stuff shows that it is at least as strong as tough Balsa. There are different grades of balsa and this stuff is not the cheep model airplane balsa. Think of floating Rapalas and the stuff they are made of. It is rated at 6 pounds per cubic foot.
Third row is Alumilite Flexible foam. I have not done density test on it, and toughness is going to be hard to compare. I guess fishing is the best test. The stuf is like a super light, closed cell, very very small cell foam. Think a firm bead topper, but smaller poors. It is rated for as heavy as 8 pounds for cubic foot, but as light as 3 pounds per cubic foot. It is probably in the middle.
