i am going to buy these nesting billys and make my stove from these

S orry to say it might not be such a good idea, they're aluminium and fine over a wood fire so long as your carefull enough to not let them boil dry, A nice set as far as ally billys go but to actually make the stove out of one might be a bit risky.I use the small one with my homemade hoblow stove http://www.bushcraftuk.com/forum/showthread.php?t=17516
Also be aware that the smallest one is somewhat wider than the 12cm billy you originally planned so if you try and usethe Ikea or Morrisons solutions they'll be packed inside the billy and need to be wrapped in something to stop soot and gunge getting on the inside of the billy.
Slightly reverse thinking here but if you've already go a Swedish army stove set why not just cut a stainless steel base for it to stand on ( maybe even a stainless steel fire grate to drop inside ) or at least keep it open as an idea incase you don't pull any of the other ideas off for lack of funds or time.
Actually it was your post here that set my mind onto trying to get something working with a Clikstand and wood ( as detailed here http://www.bushcraftuk.com/forum/showthread.php?t=22041) but I'm not that optomistic it'll work yet, I'll let you know if I get a chance in the next couple of weeks.
