Just spent about an hour looking at all of your Fotki photos. What a stupendous build. I have this 'thing' about kit-supplied chrome plated parts. If I can use real aluminum or other metal, I will. If not, I'd rather strip the chrome pieces and use Alclad. My problem has been the kit-supplied spoke wheels. The spokes are too thick to be realistic and I'm constantly looking for replacements. I found some Franklin Mint motorcycles that have excellent wire wheels, but they're not quite the right size. Any chance of marketing your front and real wheels?
The blower looks like aluminum, but I didn't see any photos on it. Is it scratchbuilt?
How did you center your drill in the headers, in order to get such a thin edge all the way around? Did you use a drill press or your lathe?
