Trash Bash Sci-Fi Fuel Drum

This was a quick and dirty proof of concept I threw together over a hot summer afternoon. The goal was to see what else I could do with a couple of plastic soda bottle caps other than make another wheel for a sci-fi vehicle. It could be almost any kind of sci-fi widget, but I'm going to develop it as a sci-fi fuel drum for 28mm tabletop gaming. The execution needs more refinement before I crank out a bunch for scatter terrain.

One thing I can't complain about is the cost of the parts.

Parts List

• Plastic soda bottle caps x 2
• Coffee bag valve x 1
• Plastic beads x 3

Preparation

The soda bottle caps and coffee bag valve got a good scrubbing with warm soap and water. Then I sanded down the edges and tops of the soda bottle caps. The edges were pretty rough and I wanted to improve how well they fit together. On the other hand, the tops were too smooth and I was concerned about how well glue, primer, and paint would bond to the surface.

Assembly

Pretty straightforward. I formed the main body by gluing the pair of soda bottle caps together. The coffee bag valve and beads were glued on what I arbitrarily decided was the top.

Spray Priming

Krylon Fusion All-In-One Matte Black

Coated all surfaces, including the underside.


Spray Painting

Krylon ColorMaster Paint + Primer Metallic Aluminum

A single coat. Since this was a proof of concept, I didn't feel the need to go further with the paint job. Later iterations will get a coat of wash and some details painted with a brush.

Moving Forward

It's good enough for a proof of concept, but there are some issues that I'll need to fix in the next iteration. I didn't notice the lettering on the coffee bag valve until after spraying on the metallic coat. That will have to get removed next time. I might play around with the number of beads and find something else to add as a detail. Reducing the number of beads from three to two would match the number of openings on a real world fuel drum. Adding an angular bit would contrast with all the curves everywhere else. Finally, I'd like to try another color for the base coat.
