Overview
I created a rivet tool to detail my Falke garage kit and it's received enough interest to warrant this webpage.

There's nothing revolutionary about it - just a 3.5 inch nail with a concave tip (bowl) and wine cork handle. Takes about 10 minutes to make one at home, but the result is machine grade rivets.

I've tried various techniques - pin heads, putty, melted sprue, styrene rod etc, but this is, hands-down, the easiest way to crank out rivets in bulk with 100% accuracy.

The tool can fabricate domed or flush rivets. Domed rivets require a pilot hole with a nub of styrene glued in place for compression. Flush rivets simply require pressing the tool directly into the surface material. A hacksaw blade can be used optionally as a guide however, once you get the hang of it, it's pretty easy to plot the rivets and do everything freehand.

Rivet scale is up to you. For the Falke, I went with a 1mm diameter because it matched the Nitto MaK/SF3D aircraft kits.

Bowl & Pointed Tips

Final

Bowl Tip
  • Bench grind the nail into a fine point.
  • Pinch the tip with 400 grit wet-dry paper and twist the nail back and forth to smooth out the cone shaped point.
  • Grind the tip flat, down to the cross-sect diameter for your rivet
  • To help position the drill bit, score the center of the flat tip with a sharp exacto knife.
  • Pin-vise/finger twist the drill bit using the score as a guide.
  • Knock the edges back a little with 600 grit - the tip is pretty sharp otherwise ;-)
  • Find a rubber wine cork, make a vertical slice halfway up, halfway deep. Embed the nail and tape it up.

Tip: To create a groove around the rivet, make the cross-sect diameter larger than the drill bit.
