More work done on the PSU rebuild:
I'm using this stuff now to glue it together, it actually works really well, lots easier to use than cyanoacrylate based glue.
It give about 10-15 seconds to get things in place and then it's strong enough to handle after about 5-10 minutes, but not full strength until 24 hours. It does melt the acrylic together, but contains adhesive as well. Just wish it came with a smaller applicator end, it's a bit messy to use the tube the way it is.
I've cut some more pieces and hope to get it fully assembled today
Still need to cut a few pieces more, but I'll glue these in place first.
