SamKidney Posted July 16, 2011 Report Share Posted July 16, 2011 (edited) Just put on my heatsink Whites, and theyre pretty good. Problem is, my shitty grinding disc wont give a sharp enough or deep enough grind for them. Just dulls quickly, and this is an Echo TR rim that should hold a grind like forever. These whites are only a stop gap until I get my Yellow refills or Rockpads. So the disc has to be able to give a nice sharp medium grind that will last So, someone recommend me the correct disc to use please Edited July 16, 2011 by Echo Lite 09 Quote Link to comment Share on other sites More sharing options...
Rockman Posted July 16, 2011 Report Share Posted July 16, 2011 I use this and it gives a really good sharp grind. Quote Link to comment Share on other sites More sharing options...
SamKidney Posted July 16, 2011 Author Report Share Posted July 16, 2011 Looks like it would rip the rim apart Quote Link to comment Share on other sites More sharing options...
Rockman Posted July 16, 2011 Report Share Posted July 16, 2011 Looks like it would rip the rim apart I thought that when I first seen it, but it doesn't it gives a really sharp grind. Quote Link to comment Share on other sites More sharing options...
SamKidney Posted July 16, 2011 Author Report Share Posted July 16, 2011 I thought that when I first seen it, but it doesn't it gives a really sharp grind. Hmmm, will have a look tomorrow. Had a quick look at the Tartybikes video guide and it says that Stone Cutting discs are generally the best. But thats what Im using :/ Maybe mines just a horrible cheapo one.

Sam T Posted July 16, 2011 Report Share Posted July 16, 2011 Dude, you seriously need to stop changing your brake set up lol. You keep saying how amazing the Heatsink Yellows are or the Tnn pads yet you still change em? 1 Quote Link to comment Share on other sites More sharing options...

You keep saying how amazing the Heatsink Yellows are or the Tnn pads yet you still change em? My Yellows have worn out man! I had the chance to grab some refills for a 5er so I did to keep me going, and im surprised at how nice they are, but they could be better if the disc Im using gave a sharper and deeper grind Im going for another set of Yellows when I have the cash Stainless Steel cutting discs any good?

Matthew_Gibson Posted July 16, 2011 Report Share Posted July 16, 2011 best one I've used is a super thin slitting disc, they about 1mm thick, better than halfords shitty cutting discs http://www.google.co.uk/products/catalog?q=slitting+discs&hl=en&prmd=ivns&resnum=3&bav=on.2,or.r_gc.r_pw.&biw=1280&bih=901&um=1&ie=UTF-8&tbm=shop&cid=13989458289056834223&sa=X&ei=QfQhTuedDJGwhAfq78mwAw&ved=0CIABEPICMAA I got a pack of 10 for around a fiver. I might try one of those diamond cutting jobbies, I like my grinds to be uber sharp. but white are a good pad on smooth IIRC Quote Link to comment Share on other sites More sharing options...
SamKidney Posted July 16, 2011 Author Report Share Posted July 16, 2011 Well Ive got a thin Cutting/ Slitting disc at home so will give that a go. Dont want to be grinding away my rim, Only had it 3 weeks and because my discs are no good I keep having to regrind :/ How long do Echo TR sidewalls last? Look fairly thick best one I've used is a super thin slitting disc, they about 1mm thick, better than halfords shitty cutting discs http://www.google.co...ed=0CIABEPICMAA I got a pack of 10 for around a fiver. I might try one of those diamond cutting jobbies, I like my grinds to be uber sharp. but white are a good pad on smooth IIRC These pads are the ones from the DIY compound heatsink sold in sheet form. Compounds harder than normal on these pads Hold pretty good, but the grinds no where near as sharp as It could be Quote Link to comment Share on other sites More sharing options...
SamKidney Posted July 16, 2011 Author Report Share Posted July 16, 2011 Had a word with jamie and he reckons that the Stone Grinding discs give a good deep and sharp grind that lasts on Echo rims. Looks like thats the way Il be going Quote Link to comment Share on other sites More sharing options...
Filo Posted July 17, 2011 Report Share Posted July 17, 2011 The stone discs are good for a really sharp grind. I found the brake have amazing bite, but only in the forward direction. I had heaps of backwards roll throughs. The stone wheel doesn't remove heap of material from your rim per grind. But you have to grind more to keep it sharpe. For best brake consistency use a 3mm cutting wheel and learn to grind correctly and you will have rewarding braking. Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted July 17, 2011 Report Share Posted July 17, 2011 Well worth changing to a diamond cutting disc... I bought a hilka one for £2 1 Quote Link to comment Share on other sites More sharing options...
Echo-SL Posted July 19, 2011 Report Share Posted July 19, 2011 I have a normal cutting disc, the grinding disc just picked up all the aluminum and wasn't a strong grind. Quote Link to comment Share on other sites More sharing options...
theom Posted July 20, 2011 Report Share Posted July 20, 2011 You need to hold the grinder at a steeper angle to bite into the rim more, ive used really worn out - near smooth discs in the past and can still get a good grind out of them. You just have to adjust the grinder to the best angle to get it to bite into the rim. Quote Link to comment Share on other sites More sharing options...
315r Posted July 24, 2011 Report Share Posted July 24, 2011 Some guy explained to me that diamond cutting disk was better than others to grind a rim. I didn't believed it, but should be truth... Quote Link to comment Share on other sites More sharing options...
