Wavy brake disc

[jedi-]

Been messing in solidworks and drew up a new rear disc. If I'm happy I'll send it to a friend with a laser cutter in a DXF. file and he said he would do it for nothing:eusa_dance:
Any thoughts to the design?

I dig it. I'm jealous of your skills.

+1 to Mark - would love to have the skills to do this type of thing!

Jedi... you and I need to put our skills together... too bad we are only 1/2 way around the world from each other! I looked into this a while back and it was almost impossible to get the good stainless used on rotors... 420 I believe. How are you going to surface grind them and heat treat them... Here is a picture of a rotor I saw go on eBay a while back and I was going to replicate it.... actually I can't find it, but it had the VMax logo cut in it 4 times around the rotor. Here is one from Galfer...

I'm going to use 304 stainless, no heat treatment possible. I probably will just machine the faces but I can grind them if I have to. I don't know what distortion I might find after laser cutting but I'm sure I can get it flat.
Decided to use this design now as per the pic.

Not to throw Galfer under the bus but, wouldn't this rotor be a little more prone to heat distortion due to only 3 retaining bolts?

You have the right idea to get it surface ground. I used 304 stainless on this one of a kind rotor I had made for my Super Magna and I failed not get it grounded. So unfortunatly it has a slight pulse when hitting the front brakes hard :bang head: Otherwise, I love it :biglaugh:

The hardest part to make that I don't see in these rotors is the floating mechanisms.

The stock one doesn't float either.

Ah, I just had to re-read your original post. I see now it is for the rear. I don't know if it would make much difference to run a solid one on the front or not?? If so it would be cool to get one larger and then I could remake some adapters to fit the increased diameter. That's where we can really improve the braking power.

My bike is 1990 the fronts are also non floating.

 

[one2dmax]

Yes, the right rear is even the same as the right front. A good set of my adapters, R1/Vmax newer Rotors, and Huyabusa Calipers and you'd have killer front brakes.

Done, dreamed up a way to machine it flat without any chatter and it worked fine. There was minimal distortion after laser which was a relief.
can't wait to put it on this weekend:eusa_dance:
