The polishing was not done to make it look good, after all, no one will see it when it is in use. the idea is to make the crank more aero and to lighten it. after it gets shipped to Winberg they will stress relieve it and shot blast it, hollow/rifle drill the crank pins,Nitrite harden, set stroke and index while grinding and polishing journals. and finally balance it.
I also honed the oil holes with a diamond ball hone to remove every possible notch or stress riser. My main focus is longjevity...form follows function.
Almost forgot......I took off 4 lbs.
