RE: New SPAD Foamy Design!
Here's a photo showing the hot-melt glue "welds" at the corners of the fuse. Hot melt glue seems relatively heavy... I'll probably have 0.8 - 1 oz of hot melt glue on this by the time I'm done! I believe you could use polyurethane glue, but you'd have to squeeze it into each corner of the fuse, prop it up so the V contains the glue and it doesn't just ooze down the side, and let it set up before going on to the next corner... and after all of that, I don't believe it would make the fuse nearly as rigid as the hot-melt glue.
