I own a motorcycle and was researching how to make "diamond cuts" on the engine fins. Diamond cuts are simply decorative cuts made in the fin edges, using a burr by hand or with CNC, to make the engine fins sparkle. Its been done for years by chopper customizers.
I came across this site
I read the patent on the government web site and what a bunch of BS! He claims to have measured the temperature drop in the engine resulting from the diamond cuts, and that is the basis of his patent. Yes, there may be some minor measurable temperature difference, but the real reason for the cuts is simply aesthetics.
What makes me so mad is that some a**hole patents the process of cutting little chunks out of engine fins, then tries to put a fellow American out of business.
This guy needs our support. I've written to him and got a nice reply. I have no affiliation ? I'm just PO'ed at what is going on here. Maybe I should patent the process of making holes in metal and wood.
