Wishlist

This is a list of random junk which I'm looking for, for various projects. In the spirit of http://uk.freecycle.org/, I like to recycle things where I can. I also have a box of odds and ends, so if you're looking for something electrical or mechanical, let me know as I might have it :)

  • Fire extinguisher/air tank
    • Doesn't have to work, but should be airtight
      • Ideally not a CO2 extinguisher
      • To be used as a 100psi air compression chamber
  • Arc welder/welding supplies
    • For welding steel, etc.
