I put the CO2 cannisters in my vice, put on leather workgloves and my face shield and broke the seal on the cannisters with the centerpunch and hammer. |
|
I used the drill to make the holes in the cannister tips large enough for the grounding wire to slide into. |
|
Used the pipe cutter to cut off the rounded ends of the cannisters. One is right near the top, the other is a bit more into the center. |
|
Used the pipe cutter to cut about 3.5" of 3/4" pipe |
|
Used the pipe cutter to cut the larger 1" portion of the reducer in half. The piece is too long, so I had to shorten it. |
|
Used the dremel with the sanding drum to remove the small stops that are inside the reducers. These are made to stop the pipe from sliding through reducer. We want it to slide through. |
|
Used the sanding wheel again on the cannisters. The pipe cutter makes a groove in the pipe when it cuts, so you need to smooth out the inner edge of the cannisters. Once you do that, the 3/4" pipe will slide into them |
|
Hot glue the 4" section of pipe into the larger (top) cannister. |
|
Slide the reducer on next |
|
Hot glue into the area inside the reducer and then slide the other cannister into the reducer. |
|
Hot glue the insulated bushing onto the reducer/lower cannister. |
|
Paint the whole thing with grey primer. |
