Fire Globe Project - Kokopelli Under the Stars.

Welcome to Peterson Metal Arts.

As a metal artist I have been around for a couple of years now but this (the fire globe) is my first major art project. In the past I messed around a lot with making strange little animals and other creatures out of discarded materials (a lot of shovels, rebar, pliers, bolts, nuts, washers, and etc.) I have also built gates, metal arches, window well covers and other types of projects you would consider functional rather than artistic. I will post some photos of these later on.

 Recently my wife and I were at a lawn and garden store and I stumbled across an assortment of tank caps. These are caps that are used on commercial propane tanks. When the tank ages and needs to be decommissioned they cut them up. The caps get "repurposed." People buy these (mostly) for large and decorative planters. When I came across them I had a different purpose in mind.

Seen next to my PT Cruiser for scale

I brought home two of these and they were in the same condition, they were completely covered in rust that had to be removed before I could start work.

Neatly cleaned now

 














I cleaned the tank caps with an orbital sander and wire wheel that was attached to my drill. This was a slow and laborious process but it cleaned both of them up nicely.

Starting to cut the top

After cleaning the rust off I drew a pattern on one of the caps and cut the pattern out using my plasma cutter. The image is Kokopelli (a native American fertility God) over his should is a full moon and in front of him is a saguaro cactus and under the cactus a coyote howls at the moon.

Had to see it lit

After cutting the stars out of the top I wanted to get a feel for what the cap was going to look like so I brought the cap into my garage put a light under the cap and turned the lights out.

Fitting the top and the bottom

The second tank cap I cleaned, as I did the first, and used my plasma cutter to cut a 3 inch diameter hole in the bottom (for venting) and welded legs to it. When the two pieces are put together they form a sphere standing on a tripod.

Burn Test

After bottom had been completed my wife and I thought it would be fun to put a fire in the globe and sit out on our patio. The light from the globe casts a warm glow everywhere. (I haven't welded the top and bottom sections together at this point)

Painted

To finish this project I sandblasted and the two halves of the globe (inside and out) and painted the entire globe with a high temperature, corrosion resistant paint. I did the entire globe with a flat black and then decided that a semi-gloss would look better. After painting the top with the semi-gloss I really liked the look of the two parts. The contrast (flat black on the bottom and semi-gloss on top) gave it an interesting appearance I thought I'd leave it that way. If I change my mind I can always paint the bottom with the semi-gloss as well.

The globe has a "Fire Deck" inside it which is to say there is a surface to build a fire on. This keeps the fire from sitting right on the bottom of the globe. Together with the 3 inch hole in the bottom this makes air flow in through the bottom and up and around the fire causing to burn hot and efficiently.
The two halves of the globe are not welded together. Between the two halves is a cooking surface. The globe is actually a BBQ grill! The top half sits not on the bottom half but on the cooking surface. The top comes off to use it as a grill and when you are finished grilling you can put the top on (the top weighs about 50 lbs.) and have some food and drinks and sit around a warm fire and enjoy conversation with friends.

This project was a lot of fun! I really enjoyed the process. I learned so much about not only my tools but my abilities. I'm really looking forward to my next project.
