Changed my mind on the plastic.....
Been playing with my lathe, and made a handle out of some alli bar i had, and it machined so nicely i love the stuff, only problem i have is parting off, still got a lot to learn,
i was hoping the plastic would be cheaper than alli, but i'm not sure it is, and should be easier to find off cuts of alli bar,
only problem i'd have is parting off the slices, that's the reason i was thinking plastic, as that stuff parts off pretty easily, but alli has a tendancy to dig in, or it does in my hands, and it takes me ages to get through a 1 inch diamiter bar, so almost 5 inches of bar and i'd have no chance.
and a really silly reason i was thinking plastic, it comes in black, and that's what the controls are, but paint will do on alli, or even anodizing,
This is what i'm trying to make, very simple, but it's the mechanics below that will be harder to replicate, for the notches and varying resistances you push against,
i have the technical drawings for the controls, sent to me by someone who works in the tech department at DB, so i have most measurments, as well as the forces in newton meters for each notch, distance between notches and so on,
i just need to get the raw materials and get making.
