I've had an empty small argon cylinder in my workshop for years, just waiting for inspiration to hit me with an idea to use it for.

Bells from old cylinders aren't new, but I finally decided to try to add my own mark to the idea.

Here is how to make your own. I hope you like my instructable.

Step 1: Materials and Equipment

As always there are always other ways to do things so use what you have available. Here's a guide.

Materials:

  • An old argon cylinder. Be bloody sure it never contained a flammable gas, and make sure it has no pressure in it.
  • Steel rod, about 8mm diameter.
  • Steel plate, about 100mm x 150mm of 3mm plate.

Equipment

  • Safety gear.
  • Welder.
  • Angle grinder with flap discs and cutting discs.
  • Drill and bits.

Step 2: Prepare the Materials

Cylinder

  • Cut the valve off the cylinder to make sure it's really empty.
  • Cut the cylinder in half - to the length you wish your bell to be (you could make two bells from one cylinder).
  • Use the angle grinder with flap discs to remove the paint.
  • Drill the centre of the end to accommodate the rod.

Rod

  • Clean any rust off the rod with the flap disc.
  • Bend the rod approximately into the shape as shown in the pictures.
  • Cut a small piece of rod to make a hook to hang the clanger (is that what it's called?) from.
  • Use another piece of rod to make the clanger. Just bend a loop into one end to hang over the hook.

Plate

  • Cut the plate to the size that suits a mounting plate for your bell.
  • Clean up any rust with the flap disc.
  • Drill holes for attaching the bell to a wall.

Test the sizes of all the pieces to make sure it looks right.

Step 3: Assemble the Bell

Carefully position the rod part on the mounting plate and weld it on.

Weld on the clanger hook.

Weld the bell part to the end of the rod.

Give it all a tidy with your grinder or wire brush as necessary.

You might like to coat it with paint or something to prevent rust. I used clear Penetrol.

Step 4: Conclusion

This simple bell can be mounted to a wall next to a door for a very loud and unique doorbell. Or it could be used in any number of other applications.

    Looks great, I'd add a need for a little chain welded to the clapper so
    to avoid, loss, theft, & use as a tool for ill... such as to break
    in using it as a lever, or window point smasher. Sorry to take this
    lovely thing into a discussion of "the dark side" but, where there's a
    tool there's a way to abuse it. Such a "negative Nancy" I know... still it
    looks great & probably sounds great too. & : the chain could negate the need for a hook.

    Thanks Danny. I did think of a chain, but I didn't have any that would be suitable in my scrap pile.

    This looks great. Nice job. It seems you made more than one as the last pic is of a different one in shape on its front and length?

    Thanks. And yes. Well spotted. The cylinder had two ends so I made two bells.

    Thanks for that. Now I think of it a "clanger" is an embarrassing mistake. Ironic.

    No need to be embarrassed, you asked for a possible correction and you got it, and it still does not diminish the creative originality of your posting. ☺
