i am terrible at the search option and couldn't find a post so if this has been asked 500,000 times please don't jump my arse and just point me to the link thanks, but is it cheaper to build a can or buy one? i work at a steel mill and have all the tools and know the guys that have the skill to do it and might even be able to get the materials at no cost but is it any cheaper? if so or not please elaborate.
