Welcome to forums.7-8 weeks lead-time on larger quantities is pretty normal in my experience. You might sometimes get lucky and it ends up being less but that's about normal.I am far from being an expert machinist, but I know a little bit... Lot of stuff going on that part. I do not have experience with RapidTurn, but I think that is a light weight solution. Tormach Slant Pro will do turning for that part easy and to excellent tolerances. You can then mill it on 770. Now to the cost of 770 alone... I doubt you can justify buying it if you do the math. If you take what you are paying to machine shop to make that part, how long it will take you to pay off 770? Add to that anytime you'd pay them extra to make you low quantity 5-10 pieces... I think you might find that it takes a heck of a long time to pay machine off. Don't forget that machine is just small part of the cost, large chunk on top of that goes for tooling.Then it will take you some time, months likely, to learn how to machine and work-hold just that one piece...I am not trying to discourage you just giving you something to think about in terms of the actual cost of making this yourself. Now if you want to make it for fun of it, then all this goes out of window, just get the machines and start making :-) Hope this helps.
