    home made rotors...(well sorta)

    being an AutoCAD operator, and having a 1.5 million dollar Trumpf laser machine at my disposal, a shortage of brake rotors will be something I hope to never encounter.

    this is a quick design I mocked up today out of some .080 stainless scrap. I see areas where I can shave some weight, so next week will be round 2

    Great project. They look good. Have you ridden them yet? I am curious to know if they are quiet under braking. I think rotors are generally ground radially after cutting/stamping but judging by the noise that some of my rotors/brakes make this extra step doesn't do much to make them run quietly.

    No rides yet.

    I'm planning on a new wheelset to mount some road-friendly tires on, so I will also mount my own rotors as well.

    I'll keep you all posted.

They are usually two piece, an aluminum carrier with a stainless braking ring attached to the carrier. The reason for the two piece design is the thickness that is required for the interface. Making one completely out of stainless would make the rotor quite heavy. Kind of a complicated design for the carrier as well.

    I would also caution you very strongly AGAINST making a center lock rotor for anything but you own use! Shimano holds a very strong patent on the center lock design. Any manufacturer of a center lock rotor without proper license from Shimano would be patent infringement. And like any large corporation, Shimano pursues patent infringement vigorously!

    Anyway, cool design. A little polish, smoothing and refining and I'd say it'd be ready for market.

    Nice work limey - What'd really be cool, is if you could do custom designs like DirtyDog and cut into their market - they're expensive!!
    (but so cool)

    Honestly, you just take a deep breath and say Fuck it.

    I could make that. I would need the bolt centers...diameter...braking surface dimension...etc.

    I would never fabricate anything to sell. I learned my lesson many years ago when an attorney for Nitrous Oxide Systems contacted me about selling throttle body plates with their logo on them for corvette owners with using their product. I made one for myself, and they saw it on my car at a national event. It wasn't but a couple weeks later I received a letter, advising me not to manufacture any for sale. They did not waste much time.You can see it here:

    That would be nice to have free reign on cutting laser. Great looking rotors. I too am interested in hearing how the performance is.

    That's really cool. I like the design too, simple but unique.

    What alloy did you use? Most rotors seem to have a lot of iron content, maybe something like 4130.

    No...I never sold any. I had a slew of people on a car forum that wanted them, but NOS seemed pretty serious about coming after me.

    As it was, to get my info in the first place, they needed to kleehawk it from my event sigh-up sheet.

    It probably didn't help that they were a participating sponsor of the show.

    A bunch of us on the Fat Bike forum are always looking for a way to space our rotors out about 5mm. A machine like this would do a real nice job of making a one peice spacer. Hmmmmm

    Have you figured out a way to heat treat them for longevity?

    I take it that you currently grind down old rotors?
    I see hills.

    I want to climb them.

    ^^^ I don't get any of that..., why not just use 6 round 5mm spacers?
    ala fat 'washers'

    Cause they won't be 100% the same stack height... Which cause some pretty problems.

    And a nice flat out 5mm alu round plate with holes should do the job. Only need a normal workshop tool set for it.
