The machining process of the crank will determine if the machines surface of the leading edge would be polished or not. It all has to do with the cutting tool that they use to chip away at it with which detirmines the surface grit
Lol, I missed your sarcasm on post#28.
I said what I said based on what you quoted as a billet:
Originally Posted by AndreasThink of billet cranks as an offshoot of forged cranks. Like a forging, a billet crank starts out as a large cylindrical ingot of steel. However, while a forged crank is compressed during the forging process, the steel ingot used in a billet crank is already forged, albeit not quite as compressed as in a forged crank. The key difference between the two is how the ingots are shaped into cranks. "The metal bar used to make a forged 4.000-inch SBC crank measures about 4.75-inches in diameter and the crank's total width ends up being 6.75 inches when the forging process is complete," Lieb says. "The metal bar used in a billet crank of the same stroke is much larger, at roughly 8 inches, weighing 350 lbs compared to 150 lbs in a forged crank. Instead of twisting and pounding the metal in different directions as with a forging, a billet crank is made by whittling away the metal so the grain structure runs parallel throughout the entire length of the crank." Due to the increase in materials and labor over a forged crank, billet cranks are the most expensive of them all. Custom one-offs carry price tags in the neighborhood of $3,000. As for whether a billet crank is stronger than a forging, because there is no consensus in the industry, the various manufacturers will duke it out later in the story and we'll let you make the call.
It seem like you are arguing for both side. First giving us a defintion of a billet and then showing us a photo of a non-billet crankshaft. BTW, a machined surface does not have a orange peel surface like the example you posted.
Atleast know what a true billet crankshaft looks like. This is and example of the truest sense the word billet: Crankshaft - Cosworth USA
I'm not going to argue over semantics. If you say it's a billet then fine it's a billet. Good for you directing us to a cheap alternative.
