The first step was to measure the amount of space between my fuse box and the block. I drew a plan for the outer box and from there I started to contrruct the box. I used sheet metal, folded it with 2x4s and a mallet. I took two lenghts of copper tubbing 20ft in length and wrapped it around a torch bottle. I used ear plugs to mark the tips so i would not confuse the two. I cut two small holes to run the tubbing.
Once the copper tubbing was inside I used a rivot gun to close it up.
I then placed the smaller chamber inside the larger chamber
Then filled the space between the two with fireblock insulating foam.
Once the foam dried it can be trimmed away.

I brake up the dry ice and pour it around the copper tubing and add a little water. I repeat this step tow or three times. The water flash freezes once it hits the dry ice. When you are finished, you have 20ft of fuel line and 20ft of alcohol injection line running through a block of solid ice.
