Tensen: It was not my intention to brag about how clever I am, and I don't mind constructive criticizm(sp?). I just don't need people going on about how difficult it's going to be, it's not constructive. Plus I'm sensitive and have a short fuse myself. I also am looking for advice on engine design, I'm not an expert in that feild either but I think I may have some good ideas and I like it when people look at them and critique them, as long as they're not just spewing out junk like "it won't work" or my very favorite "If it would work, then someone would have already done it, or they have and it didn't work." If you know what I mean. I understand most of the people on here are at least as smart as I am, if I didn't I wouldn't be asking them for help. I just wanted to let them know that I have the capability to learn this stuff. Any way back on topic, shrink session over lets talk about machine work.
