I love seeing the jigs and fixtures guys design to work on oddly-shaped castings. Sometimes the fixtures take as much time as the product, but there's no other way to do it. Einar, are you going to produce a Wright Whirlwind, or did you buy the heads for your own projects? I think when I buy my own, I'm going to buy one complete kit, and another set of heads. 10 heads assumes that you will either trash one by mistake, leaving nine, or it assumes that if all go well, you'll have *one* spare. I think 11 or 12 heads at the start, for me at least, would be prudent. With 20 heads, you'd definitely have some spares, or you can take the extras and create singles, twins, or flat-4's. The head is attractive and can create any number of engine styles. |
