I made this for kicks in my spare time. I just felt like going back to those days when all you had was a medicine bottle, a pen tube, and a small igniter. You know what I mean? Well please enjoy these pictures and comments are always welcome. :brave:

W00t, ther it is, w00t, ther it is! As basic as a mini gets. Does the front pop off when it fires? I like the paint job! Nothing says black like eletric tape!

Thanks man, no the front does not pop off. And I used clear electrical tape and then painted all of it :) .

nice job, i like the simplicity of it... though i think you should have mounted the barrel on the opposite end for convenience when spraying your fuel.

here's a pic of one of my minis that i customized with a toy gun handle (the ignitor is in the trigger's place). and i ran a hose from the butane tank i got from the lighter directly to the chamber.

That is really nice. But the reason I put the barrel on the cap was so I could clean the barrel easier, see what I mean?
