so times are hard, and cool stuff is expensive... sooo... if anybody needs the rotors drilled i can do it for 25$ a pop. plus shipping.. and if its a crazy design, 30$.... cheaper for you and helpfull to me lol. win win.
any way let me know.
il also clean and paint the centers black gold or silver for you.
 
sweet! crazy means like rotating swirl patterns.. takes longer for me to lay it out on the rotor..
basic would be like 3hole-2hole-3hole..
or 3-3-3 etc....
 
How accurate is this? Can you assure equal spacing, are the holes beveled, what's the method? Very interested in a few of these. Do you do side covers, brackets, ect? Thanks, John

+1 about the holes being beveled
spacing?
hole size?
placement?
 
I use 3/16 unless otherwise noted from whoever is getting them done.
Then I use a chamfer and make a slight bevel on the edges front and back.
I set the holes so they are centered with the stopping area.
Pattern is up to you.
I will post a pic of the rotor I'm running on my bike.
I have access to metal working tools at work and i use a press with very very strong and sharp bits.
And I can say I'm pretty accurate, not computer level accurate but I'm pretty patient and would do work as I would want it to look on my own bike.
 
Most excellent. I will figure out what I want and get back to you. Thanks!

Im in. Post a photo of your work. I was just holding my rotor last night thinking "this needs holes"
 
Here is one I did for my bike, was a test rotor but I decided to use it, I used a 3-3-3 pattern on this, but I recommend a 3-2-3 pattern if you want a basic pattern. the staggered holes are more efficient.

Hey I am interested in this as well, got me thinking. Whats the turn around time for a single rotor and where are you located so I can factor shipping cost? I was thinking of the 3-3-3 pattern or the words "HONDA CB750" drilled out in a series of holes. Is this a bad idea?
 
heres an accurate swirl pattern for cb360 (and other) rotors with proper overlap. its a google sketchup document, so should be able to quickly change dimensions for other rotors. a good hour went into making this, but can be used as a punch guide to quickly punch rotor and then drill. thought I would help you out. 30 bucks a rotor is very cheap.... you must have some damn hard bits to be able to do them for that price.

heres a pic of the finished rotor using that template. you can see some places where there are mistakes; thats because i didnt use a punch and/or rotary table to make the holes. would be much easier with those things.

right now, about a week. give or take a few days......
hmmm, the 3-3-3 would look great!and classy... im not sure how the words would look.. do you have an example?

awesome dude! thanks a bunch! this is very helpful
 
It was just an idea I am rethinking now, still might be interested in the 3-2-3 or the 3-3-3 drilling though. Where are you located so I can figure on shipping on top of the $25. Would like to get this done soon.
 
I'm willing to try anything you'd like though, so just let me know..

FWIW, I heard from an old timer race mechanic that was drilling rotors in the begining that the hole dia. should be twice the rotor thickness. Example, a 6mm thick rotor should have a 12mm hole. I am not sure how you get the effective number of holes though.
 
oxford; thats completely wrong. hole diameter should be equal to or less then rotor thickness, otherwise you DECREASE surface area.

effective number of holes? easy... how much space do you have? now take away half of it ;)


also I should mention that the 3-2-3 drill pattern will give more consistent pad wear then then 3-3-3 pattern, not to mention better gas excavation (the whole point of drilling in the first place)
