Hmm...I've got access to a drill press and some Ti bits, don't see any reason I can't do my own.  Thoughts?

I`ve drilled some before..... on my old Yam, and it had nice stainless discs. It`s not a big deal and it really helps define the art of stopping. It doesn`t matter which direction you go as long as the swept area is covered, meaning the area of the brake pad is all gonna hit some hole.

Ugh, you want the holes to overlap patternwise, so you don`t have any area on the disc that will streak. Sort of overlapping circles maybe 1/3 overlap or less, like you know how pool balls rack? But spead way out, of course.  You don`t need a lot of holes, and you shouldn`t bevel them very much at all, just break the edges, a minor kiss is good.

I use cobalt bits as the Ti ones are just plated and it`ll come off. Carbide is better but way more costly. Use PLENTY of  coolant and I used 3/8 bits but you can use anything over a 1/4 is cool. Best to clamp the disc down while you are at it to avoid accidents and stuck bits. I just layed out a pattern with dividers  right on the wheel. You could do it on paper, glue it and punch. A drill press is good-but use what you have. You may have to resharpen the bits as you go along.

Oh yea, I think Suzi`s disc is Cad plated or something-you don`t want to breathe that stuff so keep it real cool, and or wear a mask or get down wind.

Sounds harder to do than it is, more time consuming than tricky.....but really, I think this Suzi`s front disc is pretty good at stopping as is, so I ain`t gonna bother.
