Ali C Posted October 6, 2005 Report Share Posted October 6, 2005 I might have the oppertunity to have an alloy rotor made to my design by Wad. I have designed this (Wad hasnt seen it yet so I dont know if the final one will look like this) Now I realise that an untreated alloy rotor wont be much good and I dont wanna change pads. I have seen that Stans (of no tubes fame) rotors have a thin steel coating on the braking surface, I was wondering if anyone on here knows how this is done, or know of any other ways of getting a tough coating applied?

Todge Posted October 6, 2005 Report Share Posted October 6, 2005 Why cant you just get it cut from steel? Quote Link to comment Share on other sites More sharing options...
Ali C Posted October 6, 2005 Author Report Share Posted October 6, 2005 doesnt have the tools :turned: would hope make me a disk of my own design? if so, how much are they? Quote Link to comment Share on other sites More sharing options...

totaltrials Posted October 6, 2005 Report Share Posted October 6, 2005 It may possibly crack and snap if you make it like that ali. Phil. Quote Link to comment Share on other sites More sharing options...
Waynio Posted October 6, 2005 Report Share Posted October 6, 2005 £40 odd quid for a custom rotor if your Mr Joe Bloggs but if your in the trade ali im sure you can get it at cost like i have done with the 2/3 of mine i had made. they dont cost too much over a normal priced rotor really. if you have any problems getting it made and getting it at cost i will order you one from my work and sell you it at trade price? you can even have your name etched into it how kools that............. :turned: Waynio......................

Ali C Posted October 6, 2005 Author Report Share Posted October 6, 2005 allo I will probably leave it as it is and just run it with normal pads for comps only. I am gonna design more rotors (its fun :turned: ) andI have been told I can have curves in the design :) (although I still recken its the most buitifull rotor ever) Quote Link to comment Share on other sites More sharing options...

Todge Posted October 6, 2005 Report Share Posted October 6, 2005 Question - Does anyone know the exact material used for rotors. Is it just standard steel? Quote Link to comment Share on other sites More sharing options...
RobinJI Posted October 6, 2005 Report Share Posted October 6, 2005 Rotors are normaly mad from preaty hard stainless steel, although I don't know if it is usualy hardened or not. Quote Link to comment Share on other sites More sharing options...
dave33 Posted October 6, 2005 Report Share Posted October 6, 2005 (edited) ali you probly dont want to have all them sharpe corners, stress is just gonna build up there, put small rads on, as for being coated you could get coated with a process called tennifer (spelling)? which is what the do to forming tools to make them very hard, but im not to sure if it can be done on alu. you could try as a start to get it heat treated and try that as i dont think your gonna get the same heat build up with trials as to down hill and i dont see why they can made one from steal as you would use the same cutting tools just a much lower cutting speed :turned: looks kool though and good luck with it Edited October 6, 2005 by dave33 Quote Link to comment Share on other sites More sharing options...
Ali C Posted October 6, 2005 Author Report Share Posted October 6, 2005 yeah, its just the drawing that has straight edges, if it was made they would all be rounded off. I will deffo see about heat treatment, seems like a good idea Quote Link to comment Share on other sites More sharing options...

Will Arnold Posted October 6, 2005 Report Share Posted October 6, 2005 im sure plazmatic coat discs, maybe you could find out what kindof coating they use? anyways, it looks nice that ali :turned: Quote Link to comment Share on other sites More sharing options...
Ashley Smith Posted October 6, 2005 Report Share Posted October 6, 2005 discs arnt made from stainless, i think they are made out of gauge plate but dont quote me on that ash Quote Link to comment Share on other sites More sharing options...

Ashley Smith Posted October 6, 2005 Report Share Posted October 6, 2005 gauge plate is a form of steel but a lot harder with a more distinct grain, i will find out as i know the designer at hope, there not stainless anyway because they go rusty where they have been laser cut on the inside its ash Quote Link to comment Share on other sites More sharing options...
dave33 Posted October 6, 2005 Report Share Posted October 6, 2005 i think its when the plated is rolled over and over and heated and cooled, not sure though Quote Link to comment Share on other sites More sharing options...
dave85 Posted October 6, 2005 Report Share Posted October 6, 2005 Gauge plate is a medium alloy steel, easily hardenable and usually supplied in accurately ground flat sections, for making jigs, dies, gauges and the like. Hellishly expensive would sum it up well. Quote Link to comment Share on other sites More sharing options...
totaltrials Posted October 6, 2005 Report Share Posted October 6, 2005 In nearly all cases they are stainless steel. If your not assed about the weight ali you should try some beasty iron discs, get an old motorbike disc brake chop one side of the disc off and surface grind it down and drill the holes in the relavent places, that would be a beast, but may rust rather quickly.

dave33 Posted October 9, 2005 Report Share Posted October 9, 2005 just reading a disc packet today and yes it was stainless steel. that was an aztec rotor (Y) cant realy surface grind rotors as they tent to have magnetic tables thus pulling the disc flat and after you grid and take it off the bed it springs back to its original shape and you have high and lo spots, unless its perfectly true and flat :- Quote Link to comment Share on other sites More sharing options...
