I have different guns for different environments, so I have no favourite as such and most of my guns are old metal piston jobs. For the "seaweed jungle", which one pulls their way through at times rather than swims, I like the "Taimen", plus I know that gun inside out by now which will not be a surprise to anyone! In open water anything with a 40 mm OD tank suits me and a decent handle that fits my hand.Your personal opinion counts for me Pete?
Injection moulds or dies are very expensive, they have to fit the moulding machines and have sprues, gates, runners and moving inserts to create voids which then withdraw to allow the product to be ejected. They have to be highly polished and resist erosion and distortion as the molten plastic squirts in at high pressure. My Dad was a toolmaker and made injection moulding dies for simple household products.The tooling don't actually have to be that expensive. If they know how to design an injection mold to industry standards, which they might not - then it seems like they have the CNC capabilities to make the mold itself in-house. They could possibly then hand over that mold to an injection facility as that is not cheap machinery, either.
Another reason for not going with Delrin for the handle is that it is slippery as hell. And nothing really glues to it. So, it won't be easy to make it more grippy or modify it for your hands.
Do we not just use a 3d printer these days and make what we like? (I havn't even seen one out of a shop window yet)
Well, in a few years... Only now, materials that are sturdy enough are arriving on scene. Also, when people say "everyone will 3D print at home" they tend to forget that a lot of people can't do the 3D design. I think that will be the real bottle neck.
That said, if interested in these things, I think Onshape.com is on their way to something good. I have done some pretty OK 3D modelling in it and I have zero CAD experience.
Anyways, I know you were kinda joking. Interesting nevertheless.
Here is a guy who has a couple of 3D printed band guns that do actually work, but he has designed around the current limitations of the technology if you work your way through the text and absorb what he says.
