Propane Tank-ard Insulated Beverage Bottle

Step 5 Cut a Hole in the Bottom

Cut a hole in the bottom of the tank.

The bottom of the tank needs to be removed to allow for installation of the plastic bottle "liner". The diameter of the cut hole should be just inside the fluted "peaks" of the tank's bottom formations.

Starting with the Bottom Hole first allows the tank to be cut while holding it by the top threaded fitting clamped in a vice.  (don't worry about damaging the threads on the top fitting; this whole stem will be removed later.)

Leave the "Peaks" of the tank's bottom arris formations (photo 2) so that the tank will sit level when the Plastic End Cap is replaced.

What did you use to cut the hole?

I used a hacksaw and kept spraying the blade with wd40. It took time but came out well! I then used a dremel to smooth the edges. I had problems drilling out the side valve so I used the dremel again with a cut off blade!

I would like to second the motion to disclose the tool used to cut the tank please :) Would you advise to wash out the tank through the valve hole?

Thank you very much.

To cut the bottom hole I used a reciprocating jig saw. I did not wash out the tank before cutting. I removed both valves let the tank sit for a day and then blew compressed air into one hole for 10-15 seconds. I skipped the water rinse to avoid promoting rust
