shovel Posted September 17, 2005 Report Share Posted September 17, 2005 ok, a new grinding disc is always a good start its not really how much pressure you apply when your grinding, but its the angle you grind at, if you hold the grinder at a steeper angle to the rim then it will grind into the rim more than over it hence giving you a harsh grind be extra carful when applying a harsh grind as its very easy to get carried away and demolish the rim Quote Link to comment Share on other sites More sharing options...
An_toin3 Posted September 17, 2005 Author Report Share Posted September 17, 2005 cheers :'( Another question.., when i throw myself backward the brake is slipping and you can hear a "swoosh"? is it normal ? because when i'm going normally ! the brake is very powerful !doesn't slip at all :D going like this : "-->" = very strong ! like this : "<--" = Not strong at all.. swoosh sound!

ghosts_cloak Posted September 17, 2005 Report Share Posted September 17, 2005 Hi there! I was wondering if a grind worked better in one direction than another - I guess that answers my question. Im looking to grind my rear rim, in what direction do you do it can anyone explain. I think I know but I want to be 100% before I take a spinning disk to my new bike!!

SQuiT-man Posted September 17, 2005 Report Share Posted September 17, 2005 Try having the brakepads set up correctly, flat to the rim, and have the grind in lines pointing DIRECTLY towards the centre of your wheel, towards the hub. This should help stop your brake working one way better than the other. Quote Link to comment Share on other sites More sharing options...
ben Posted September 17, 2005 Report Share Posted September 17, 2005 the direction you should do a girnd in is if ur right handed and the rims in front of you on the right hand side go form top to bottom if tham makes sence :'( Quote Link to comment Share on other sites More sharing options...
flipkickbs Posted September 18, 2005 Report Share Posted September 18, 2005 The grind should be going opposite directions for each side of the rim giving hold both forwards, and backwards, simple! :'( Quote Link to comment Share on other sites More sharing options...

ghosts_cloak Posted September 18, 2005 Report Share Posted September 18, 2005 Does it work well? My grandad has an angle grinder, but he has really put me off using it - he said that it cuts through bricks like cheese and that if I try I will cut my wheel in half!! (Im not that great with my hands - maybe he has a point!) How easy is it to slip up and cut your rim in half / gouge a big chunk out. My grandad thinks its inevitable, is it really that bad? My grandad has suggested taking a wire brush to the rim and thinks that will roughen up the surface? A good idea? How did you find it an_toin3?

joe b Posted September 18, 2005 Report Share Posted September 18, 2005 Yeah mate. You want a steel grinding disc, and dont push down just put more pressure down if you know what i mean? (Y) Cheers, Joe. Quote Link to comment Share on other sites More sharing options...

Nah, to get a decent grind you have to press pretty hard. There is no danger of grinding through your rim unless you go nuts. Quote Link to comment Share on other sites More sharing options...

philking Posted September 18, 2005 Report Share Posted September 18, 2005 Yeah, tomm is correct, you do need to apply a decent amount of pressure to have a nice rough grind, and you would have to really cock up to damage your rim. Also, a wire brush doesnt work atall, it is crap - it has been tried, believe me! Quote Link to comment Share on other sites More sharing options...
JIX Posted September 19, 2005 Report Share Posted September 19, 2005 (edited) I always do my grinds totally 90 degrees to the rim, as in straight down on it. This i find gives a grind that works both directions very well. There are loads of topics on what disc to use so you can search them out, but I find the best way is to go to home base and buy a couple of different ones and try them yourself. They are only like 70p. I prefer to use a metal cutting disc. Also a tip I would give is to do it fast and hard. If you spend to much time on one area it will end up making it smoother rather than rougher. So I press real hard and run it over the rim quickly. But again you have to play about your self to see what works best for you. Dont worry about damaging your rim. They have loads of sidewall and grinding (even harsh) doesnt take that much off. And Im not even sure how hobbsie managed to do that to his rim, but luckily for him its a mavic. Also if you grind at an angle not 90 to the rim then one direction will always be weaker.

ghosts_cloak Posted September 19, 2005 Report Share Posted September 19, 2005 Hey guys! I got my grandads grinder out today and had a nose, it is so loud :P I had a headache afterwards! I had a quick practise on a piece of metal he had lying around. Im going to get a new metal grinding disk soon and then go for it later this week :) Just need to order some new pads in first - Koxx Reds I thought would be good... On a side note, whilst I was there I made myself a "hop-o-meter" :) It looks decent enough ;) Thanks for the advice, ~Gaz Quote Link to comment Share on other sites More sharing options...
