I think that a backup plate would be sufficient for tapping threads into.  I made a "practice" stove first just to see how it was going to work, used a drywall screw with no added reinforcement.  Fired it half a dozen times and it worked just fine, but it was starting to get a little loose.<br><br>The wire on mine gets to hot for anything to be wrapped around the top, but i did file the edges of the wire so that all of the edges are smooth.  It hasn't scratched the bottom of my pot but it's stainless which i believe the personal cooker 1 is also.<br><br>Didn't think of the stable bottle, it should work well.  I used a two ounce flip top bottle because it packs well inside of the pot.  A bottle that carries more than the one i use would be better for hiking.
