It works very well for me. I have four torches and use them all for various reasons. Here are the pics on how to make the holders. The water keeps the tanks from freezing. I add hot water, then stop in two hours, take abreak, add fresh hot water and I can use the whole canister in one sitting.
I also added a picture from the person I copied the idea from. I also added a pic of how can use the fat short canisters.
