You may use them. I used an empty disposable freon tank for my larger cannon and a disposable propane tank for my Marshmallow cannon. I would not consider either build ghetto. Using free materials is fine, but ghetto has a particular style to the materials and construction. To qualify the quality of the materials used and the construction both must be up to the ghetto standards. Somehow I think a rusty iron pipe would qualify in the materials department. Hydraulic fittings and brass pipe while free may detract from the build in the materials department.wyz2285 wrote:two questions before i get in to this:
1, I have found a metal tube in the trash but pretty new, may I use it?
2, one of my friend gave me some hydraulic fittings for free, may I use it?
If all goes well I will post my tomorrow afternoon (london time)
Study the construction of the award itself to see excellent examples of the quality of materials and quality of the build. It is an excellent example. Even the great quality of the photo with attention to resolution, color rendering and contrast add to the quality of the award.
(eximanes self submission) Hmm, I need to do stills from a cheap webcam for photo submissions from now on in this thread. I missed that one.
