planet x alan Posted February 10, 2008 Report Share Posted February 10, 2008 Heard about these a few years back...few questions.How exactly is it done?Can i do it myself?If not, who can?How much will it cost?And am i right in thinking that they work a lot better than a standard grind, last longer and are quieter?I did search this but nothing relevant came up.Cheers Quote Link to comment Share on other sites More sharing options...

planet x alan Posted February 10, 2008 Author Report Share Posted February 10, 2008 Seen it a while ago, Some guy machined the surface of his rim to like the same sorta thing as the surface of a file... a DX32 if i remember rightly. Called it a Singapore Stop and it made the braking shit hot. Quote Link to comment Share on other sites More sharing options...
Mike Winton. Posted February 10, 2008 Report Share Posted February 10, 2008 What are you on about exactly?Its like a grind, there was a post about it sometime last year, similar finish to that of the teeth on a file.Like a cross hatching on your rim instead of a grind.

SCOTTY___ Posted February 10, 2008 Report Share Posted February 10, 2008 ive been considering myself, having a go at work, but the idea in my head.. i doubt would work.. ;p Quote Link to comment Share on other sites More sharing options...
basher Posted February 10, 2008 Report Share Posted February 10, 2008 Suposidly it wasnt knurled, i remember the topic and the lad said he was told how to do it but wasnt allowed to tell anyone else. Yeah there was a dx32 if i remember rightly either machined or knurled but suposidly it wasnt done like that. Quote Link to comment Share on other sites More sharing options...

Revolver Posted February 10, 2008 Report Share Posted February 10, 2008 it would be interesting, but, loads of people like ground rims, so maybe manufacturers should make rims knurled?I think knurling your rims would be better than grinds, but if you were to do it, the pressure needed to make the knurl work could possibly collapse the walls. After all, rims aren't really made to withstand being squashed from the side like that, its a force that is pretty much non-existent on a bike Quote Link to comment Share on other sites More sharing options...

Mike Poyzer @ Onza Posted February 11, 2008 Report Share Posted February 11, 2008 We made samples and tested them about 4 years ago. Abandoned it on the grounds of cost. A very expensive process. Quote Link to comment Share on other sites More sharing options...
Joe Aston Posted February 11, 2008 Report Share Posted February 11, 2008 I remember reading the post apparently it was rubbish as soon as it got a little damp. Just get a grind. Quote Link to comment Share on other sites More sharing options...
MadManMike Posted February 11, 2008 Report Share Posted February 11, 2008 I remember reading the post apparently vee brakes are out. Just get a disc.I just got off the phone to the year 2000, they want their HS33's back Quote Link to comment Share on other sites More sharing options...
Walleee Posted February 11, 2008 Report Share Posted February 11, 2008 It was CNC machined on the DX32 that your talking about. I started or at leats posted in a topic about it when I first joined here, some arsehole said it was knurled, he clearly hadn't read the original thread on OTN. but yeh, not really a cost effective option....

SCOTTY___ Posted February 11, 2008 Report Share Posted February 11, 2008 Onza did them on Reggie and Ronnie rims a while back.That isnt a knurling process, looks like something of an old milling finish ;p the worst finish on a S.F guage for milling Quote Link to comment Share on other sites More sharing options...
SCOTTY___ Posted February 11, 2008 Report Share Posted February 11, 2008 Looks good.I thought the idea behind the grind was to create 'sharp' edges on the surface to bite into the pad materials. Surely a surface like that would require a softer pad to mould to the shape, I can't imagine it being very 'sharp'. It also looks very deep, wouldn't thicker sidewalls be needed to hold the strength?trust me, its a rough as a bears arse after a phat shit Quote Link to comment Share on other sites More sharing options...
Mike Poyzer @ Onza Posted February 12, 2008 Report Share Posted February 12, 2008 That was a photograph of the sample. Worked very effectively. You can only do this process by such CNC machining. The most effective format and profiles would need a lot of trial and error. You cannot Knurl a rim surface. Knurling is effectively an embossing process and requires back support for the surface being knurled other than on a totally solid profile. The only possible way to knurl would be onto the flat sheet before the rim is profiled and as only steel rims are produced in this way and most rim profiles these days are extruded alloy, that also doesn't work.

spaceman Posted April 5, 2008 Report Share Posted April 5, 2008 Singapore Stop?! That names mad gay, son.I think everyone decided that a grinder is a much better option.Maybe someone from Singapore made it? But I have to agree (though I'm from Singapore), that the name sounds a little gay. Quote Link to comment Share on other sites More sharing options...
