Gas cylinders come in a variety of sizes and colors depending on their original use. In our case, we had a few left over from Blog Cabin 2015. A small white propane tank would make a wide, shallow hood, while a longer yellow oxygen and green carbon dioxide tank would make deeper balloons typical of pendants. /P>

Old tanks can be found in welding shops and junkyards. If possible, remove the valves before purchasing. Flammable gases, oxygen, and pressure vessels can be extremely dangerous. Be sure to fill each tank with water before cutting to ensure old gases are fully displaced.

The easiest way to cut thicker walled tanks is by using a plasma cutter. A plasma cutter uses compressed air blown through a high voltage arc to create a current of plasma. It will also leave a unique edge to the metal cylinder.
Thinner walled tanks can be cut using an angle grinder and fiber disc. If you don't already have a plasma cutter, they can be rented from many tool supply houses. Due to the intense UV light and heat involved, regular welding equipment is needed, so make sure you have a shielded mask and gloves available.

Test your amperage settings on steel of similar thickness so you can get the dialed-in cut speed without ruining your cylinder. Grind a bare section of steel before placing the ground clamp to ensure metal-to-metal contact. For thicker tanks, you may need to increase the amperage while lowering the cutoff speed. Also, start by dipping the plasma tip into the steel at an angle so that the molten part comes out of you. Once the plasma has passed through the wall, tilt the tip back, perpendicular to the cylinder.

When using an angle grinder, it may be easier to follow an existing weld line to keep the cut perfectly straight around the tank. Make sure to go slowly so the blade doesn't catch and jump out of the cut. Feel free to alternate between straight and angled cuts to meet your desired design style.

Because the weight of the gas cylinder can be too heavy for most pendant light kits, we use 5/32" stainless steel cable with clamps to support the weight. Feed the plug end of the light kit through a center hole in the top of the barrel and tighten the cable clamp against the stainless cable.Adjust the desired height of the pendant by placing the clamp higher or lower on the cable.

Because every gas cylinder is different, mix and match them for a truly unique look. If you want more ambient light, use clear or soft white bulbs. We wanted accent lighting, so we used Edison-style bulbs.
