Thanks for the info; from a picture Limbhanger showed me of some casting imperfections in an Osprey riser, it looked to me like an investment casting. This does kinda concern me, though. I've always thought the weakness of the osprey riser over the milled risers was "trumped up" but if they use metal molds, I'm kinda concerned about internal imperfections. But then again, you don't see many breaking. I still think a "single end mill" riser is possible. I think a standard end mill could be used alone: the tip for maching flats and the side for machining all radii. With some standardization in the designing stage, it could even be used to drill the holes for the cam axles, idlers, berger hole, and maybe more. I think the problem is in the design. The designers and the makers need to get together and design one that could be easily machined.
It would be nice to know the actual breakdown of the costs that go into an Oneida. Transparency is important in business. Consumers are not always as dumb as some people believe. What keeps Oneidas out of many hands is the fact that people look at an Osprey and then they look at a fully machined wheel bow and say, "Why can they machine a riser for this cheaper bow but Oneida can't machine a riser for that one?" Compare an $800 wheel bow to an Osprey and most of them have a very large riser with a tremendous amount of machining done, not to mention very large, intricately machined cams. Some of us are willing to pay for the performance we like so much, but many are not. Saying, "it's the best" just doesn't cut it for many people. I think there is a lot of room for improvement and I hope JP makes it happen.
