David.

 

[chrisbond69]

yeah same pattern i like them got them at a good price, so well impressed only took 3 days too,

 

[Olly20VT]

Ha Ha i did mine on a CNC machine at work.
what cutter did you use? i found a 3mm bullnose and 1mm deep.
That way when the patern has gone its time to change discs, also did you do both sides of both discs?
Looks good.


3 days !!! i take it that was wrighting the program aswell.

 

[chrisbond69]

yup both sides and yup bullnose colbolt cutter 1mm thick, looks good dont it,

 

[Olly20VT]

yeah i did run ATE power discs for a wile then when they stoped making them i thought i might aswell do it myself.
Got my dad to draw it on CAD then got a guy at work to dp the CNC program then machined it myself takes 1 hour to do both front discs.
I'll be doing this to all my discs from now on.

 

[chrisbond69]

yeah i killed a normal bullnose cutter and have limited access to the cnc machine, took about half hour per disc but uncle has experience,

and badger5 has just finished the 1st batch again, after a long delay @ machine shop.

 

[chrisbond69]

out of interest how much you selling yours for bill

 

[ibizacupra]

£47.50+vat per disk - Brembo Disk

 

[deanrankin85]

i brought standard disks and drilled holes in front and rear disks on CNC. got a pattern draw up on CAD. calculated where the ribs were on the vented disks and drilled straight through. saves paying extra! look cool too!

 

[ibizacupra]

drilled=cracks which is why I never offer it.

just a question of time.

 

[Cupra R 231]

Yeah I'll agree with the cracking.....
Got a 4 pot conversion for my old pulsar gtir and thought what the hell I'll have the drilled and grooved discs... A year later big crack formed from drilled hole followed across to a groove and then right to edge of discs and I belive they were brembo discs mounted onto ally bells so a good quality disc....
Steer clear from drilled discs from now on.......

oh well, at least they look good! ill just have to keep an eye on them!

i dont drive it too hard anyway, i leave the hard driving for my corsa!

thanx for the warning.

 

[Cupra R 231]

Trust me you'll know when they've cracked!!!!!
Was certainly very apparent when 1 of mine did.....

they werent expensive so wouldnt be too upset if they did crack! ill put straight grooves in next time or even just use a ball nose cutter instead of drilling all the way thru!
