Step 11: Optional but recommended: file the bolt tips or add a buffer
The bolt tips have sharp edges, so it's advisable to round them off, either with a file or a grinder.
Alternatively, you can buy little nylon caps at your hardware store, or put a drop of J-B weld on the tip of each.
I personally plan to grind mine with a dremel because I like the clear sound of metal-on-metal when I'm truing a wheel.
I'll add a pic when I get it done.
