Okay, I'm back and my blood pressure is back to normal and I will learn to ignore unhelpful people. Yes the yoke is like the one in the Bourke engine, oddly enough I thought of it myself before I ever knew about the Bourke engine, but a few years ago I discovered the website for the bourke engine and it laid to rest my fears that the yoke might not work. I think my design solves some of the issues with the Bourke like vibration, and size.
I have a garage that is about 18' x 24' (I'm looking out the window guessing). It's full of junk but I'm pretty motivated to clean it out (not my junk). And if I need more my landlord has a building about 1/2 a mile away that is about 30' x 100' that I could use part of if I need to. It currently has a dirt floor and no electricity but the adjacent identical building has his cabinet shop with 3 phase power in it and it can be hooked up easily. My initial equipment budget will be $5-10k and I have been looking at mills and lathes on ebay and there are some deals to be had but I guess I don't really know what I'm looking for.
I'm sure I will start with some exercise projects and eventually make some scale models and mock ups of my design. The fuel injection system I have invisioned for the design as well as the turbo are not really DIY projects but I would like to work some of the bugs out of the basic design and prove it's viability before I try to do anything commercially with it. And if nothing ever becomes of itcommercially it will be an exciting hobby. Thank you all for your input.
