Thanks for your reply ZUG, though it didn't really answer my previous question hehe. Allright, here are a couple of things to consider:
1) I live in South Africa, not the USA or some other first world country. To obtain black powder is already an issue here, so buying accessories like flasks and measures etc. is basically non existent.
2) I do own my own engineering company with CNC machines, so I have all the toys to make anything I need. That however does not mean I do not have the time to make these items or pursue my hobbies. Weekends are there for a reason hehehe, and this small functional flask won't need specialized machines to make at all. I can just make this one at home.
3) I am a designer, tinkerer and a maker by heart, so I never just go out and buy stuff. I always enjoy to make stuff for myself, because I love the learning process it provides. There is of course a healthy cut-off point where I realize to just go out and buy an item IF it's readily available AND if my input costs will be much higher to make it myself.
Cheers!
