Joining polycarbonate

For the guys using polycarbonate housings.

13 years ago I made a rectangular underwater slave strobe housing out of 3/8 polycarbonate.

I used dichloromethane to join the pieces together. It melts the material. When it flashes off, 1 solid piece.

I went down in the basement and found the housing. It looks as good as the day I put it together. The joints are prefect.

The only thing, the part tolerances have to be damn tight. The stuff wont fill voids, it is the consistancy of lighter fluid. A good mill tolerance is needed.

Just some more info.
