Hi everyone!
I think my statement misled some folks.
I don't intend to actually "hack off" length from my spindle. I was simply trying to determine the actual length of my current spindle so I could replace it with a new sealed bearing BB to create the correct offset for my chainline. I have measured the chainline difference and feel comfortable in my measurements. The only thing up in the air was the spindle length of my current BB. Although the current spindle is asymmetrical, The shorter length was on the drive (chainring) side, and flipping it would not create the desired chainline. I just wasn't sure about my measurement of the overall length, which I suppose is what you get when using a $5 caliper from Home Depot
Thanks all for the helpful input and I will update this thread to share my success, or failure, when it occurs.
