What is your background? Do you have any experience in design, machining, or manufacturing? I've seen a lot of visually appealing designs from people who have downloaded a CAD program but are impossible or prohibitively expensive to manufacture. Even if you come up with a good design and build it, often the economics just aren't feasible to go anywhere with it. I'm speaking from experience.
That being said, there's a lot of experience on this board to pull from.
I am not very experienced in design, But I am pretty good at solving problems.
I have welding, metalworking, carpentry, Hobby electronics, Basic Computer programming, 3d Printing, Basic CNC milling, etc.... And I am pretty good at lego as well.
I am attempting to learn as I go on this one, and so far it seems to be going well.
Like I said earlier, I am paying more attention to manufacturing process, over aesthetics, or weight savings, so I should have a lot of room for over/under cuts.
I am also building this design around being able to do it at home without expensive machinery or specialty cutters. ... That way, I can easily set it up for CNC manufacture if the whole thing works out.
I would hope that cost of manufacturing could be kept low, and relatively simple, so if the RCMP blesses the project it would be profitable. But it not then it will only ever be an amazing learning experience, and a great story at the range.
Have you undertaken a similar project? I would love to compare notes.
