trials_noob Posted August 23, 2006 Report Share Posted August 23, 2006 I don't have an angle grinder and can't afford one just now. I know they may not cost very much to you but i have just spent quite a bit on my bike and parts. So please no replies like "just buy a grinder".I need to know if a rim can be given the same effect as a light grind using something like a metal file or a stanley knife etc?Thanks Quote Link to comment Share on other sites More sharing options...

mark145 Posted August 23, 2006 Report Share Posted August 23, 2006 (edited) Hi I had the same problem as you, until i had a rummage in the shed, i found an attachment for a drill and another twenty minutes later i found a metal grinding piece I have seen it twice once in my local 99p shop and once in hombase, in there it cost £3 and 99p in the 99p shop. I have also seen the actual discs and they vary in harshness. In my opinion this works just as well as a grinder and is just as quick, i have had the same grind for about three hours riding and it is still as rough as when i did it. I have included a couple of pictures. Edited August 23, 2006 by mark145 Quote Link to comment Share on other sites More sharing options...
rids Posted August 23, 2006 Report Share Posted August 23, 2006 if u have a harsh file and drag from inside to outside it will work but hope u have time on your hands Quote Link to comment Share on other sites More sharing options...
carnagr Posted August 23, 2006 Report Share Posted August 23, 2006 You can score the rim with a knife, which apparently has the same effect, or better, than a harsh grind, but it eats away at pads faster. Quote Link to comment Share on other sites More sharing options...
Fishy Posted August 23, 2006 Report Share Posted August 23, 2006 Don't use a stanley knife, not worth it at all. I did a big topic on it ages ago, with pictures, but to do a whole rim took me absolutely ages, and lasted at most 3 big all day rides.Something like a harsh file would be better.

20inchsuperstar Posted August 23, 2006 Report Share Posted August 23, 2006 (edited) bit of a pikey solution but my mate decided to cover his rims in coke? dont ask why he did it to start with but it works briliantly, lasts about a week and and is seriously cheap Edited August 23, 2006 by 20inchsuperstar Quote Link to comment Share on other sites More sharing options...
Sam Oliver Posted August 23, 2006 Report Share Posted August 23, 2006 For a budget grinder try argos £14.99 & 12month guarantee can't go wrong! Quote Link to comment Share on other sites More sharing options...
max-t Posted August 23, 2006 Report Share Posted August 23, 2006 ive tried them drill piece discs before and its pretty good.but takes a while...this is just an idea i dont know if it would work but what about rubbing a wire brush on your rim? or maybe if your loaded scratch a diamond across it..(even more time consuming)sorry for the last idea it was pretty pointless but good luck best results...drill piece...max..

james@weston-spencer Posted August 23, 2006 Report Share Posted August 23, 2006 on my onza i bought a cheap £7 grinder from a place called jtf (trade only though) and attacked them, definitely works, think i may have gone over the top thoughwhen my mate grabbed the back wheel when i was about to hop on a box, he knew about it becuse it cut his hand open james Quote Link to comment Share on other sites More sharing options...

rids Posted August 23, 2006 Report Share Posted August 23, 2006 just had a go with an old wood saw on an old rim it works ok Quote Link to comment Share on other sites More sharing options...
trials_mad Posted August 23, 2006 Report Share Posted August 23, 2006 I would suggest searching for pad reviews and see which pads are the best for your rims etc because you don't need a grind to have a good brake unless of course you intend to ride in wet conditions. You could try some tar on your rims aswell.But if you still feel you need an angle grinder then you can hire them from your local plant hire. Or of course borrow one from a mate.

AdamR28 Posted August 23, 2006 Report Share Posted August 23, 2006 To do a grind you really do need to use a grinder... there's loads of other ways of imitating a grind, but none of them work the same they're usually a shed load of hassle!

trials_noob Posted August 23, 2006 Author Report Share Posted August 23, 2006 OK thanks everyone.I guess the thing to do is just get a grinder or one from a mate! I'll try giving it a shot. Also whilst this topic is recent how many grinds could be expected out of a new Onza t-bird rear rim before the sidewall is too thin?And is a light grind best? Actually i think it's time for a search.....Thanks for the help Quote Link to comment Share on other sites More sharing options...
Ewannnn Posted August 23, 2006 Report Share Posted August 23, 2006 All you want is a light sharp grind. So if you do buy a disc for the grinder best get a metal one not a stone one Quote Link to comment Share on other sites More sharing options...
Willsey Posted August 23, 2006 Report Share Posted August 23, 2006 you could just sand it down, but i would suggest trying a local car garage, like a bodyshop garage (like my dads) not a dealer like ford dealer or something and politely ask them if they would be kind enough to quickly wiz over it.. my dad would if he was asked.. he gets kids coming in asking him to tighten there seats n brake leavers, bless lol, and he would.. so a lil grind over wouldnt be any trouble.. im sure if you asked nice enough they would.. just make sure they dont grind it too hard lol Quote Link to comment Share on other sites More sharing options...
