Hi there.

I was thinking of making up a new rear disc. Designing the thing isnt a problem. I can easily draw up a new design, nothing too flash...just make the outside edge a bit wavey and cut some "cbr" logo's into it.. I have quotes on laser cutting out the disc from 5mm Stainless plate, but i cant find much info on the type of stainless stock to use.. Ive heard that a 400 or 420 series stainless is the way to go?? and engineers out there who have chewed over the same fat in there heads.... Also hoped that someone could recommend a pad/combination that works well with the stainless chosen (save me from trying out all the combinations).

Cheers

that's a unique approach.

me? my unedumicated guess is the harder the steel you go the softer tha pad you want but all that depends on how you use your brakes I'd say. but that's just a thought...

I had mine done a long time ago, got the information from Kyle Racing site and send it out, had it back the same week for a little bit of money

Yep, ive been to his site.. - some nice things there.. I had thought of drilling out the disc holes, but then i went down to the local laser cutting shop here..they'd cut out a design for about $60 (aussie) as long as they had a DXF file of the design...luckily i was an Engineer in a previous life so have the CAD capabilities LOL.. Also i do work for a FAB shop, so geting some plate will cost me beer tokens...just need to decide on a reasonable "look" and what exotic Stainless to use..

I like it, once you start making em I may look at getting one from ya with 1wheelmax and 1000rr.com on it.

Even if I don't mount it it would make a cool thing for the wall.

Well ive stuck the drawing on the bike to get a rough idea of what its going to look at... apologese for the bad pic..but its a camera phone lol

Once i get this made, ill post the DXF file and you can just take it down to your nearest fab shop (that have a laser cutter and you can do your own.. As im in Australia, itll work out cheaper that way i guess.. Just want to chat with someone into brakes and suss out the best Stainless mix, and maybe a preferred pad for stainless....The design is far from the minimalist designs ive seen so chances for warpage or pretty remote...

let me know when you are ready to put up that DFX file. I'll put it on the forum's host and set a link to it. you can email it to gntbldr@yahoo.com when the time comes.

that, my friend, looks awesome.


I have a friend that has a plasma cutter that the DFX file will upload to and don't be surprised when you see that design on a few of our bikes here. :D :D :D
