I don't like it. But that's just because of my anti-combustion bias
Objectively, it's a very well made cannon and my only criticism is that you left the handle unpainted.

It looks nice!
Finally another non-USA cannon that uses european (or dutch) fittings!
I thought I was the only one with those kind of fittings
Paint the handle and the barrel

The fitting is home made, It was a capsule. have drill a big hole in it and and it permanently melted. The painted PVC was grey, olmost everything is grey here. I have taken blank for the rest because I that beautiful find. We do not have here also of that beautiful funnel pieces

Only ugly with the breach for the barrel to the upper part.

you made that screw-on barrel yourself from a screw-on cap?
might be a good idea, coz they dont sell many unions here in holland

Meanwhile I've modifeded the gun a little bit. The barrel was broken so I had to replace it with anotherone. I chose a smaller one, so it became more like a handheld. Here's the new picture:

you would rather tote around a pump or compressor? :snorting:
a small tank of propane is easier to carry and use.

A small tank of propane is heavier than a pump...
Pneumatics are stronger, but simple combustions are more portable(Simple combustions only need deoderant or something.)
