    Homers: tips on truing rotors?

    Bent the front rotor on my RFX from crashing last week so it rubs in the caliper (J7s) a bit. I've done the typical adjustable wrench truing, but still have some high spots in both directions, so I'm looking for alternatives. Anyone had luck clamping a rotor between 2 pieces of 1 by pine or oak to flatten the rotor, or would the wood simply be too soft?

    the problem with yer wood block solution is ya need to overbend stainless to make it hold shape so this wont work. if yer carefully home truein and it still wont go straight, i see 2 options: go to a shop that has the proper tools like trueing forks and a dial indicator, or buy a new rotor. hope that helps.

    What Jag said: Morning Star Drumstix

    You can work a high spot by holding the adj ends at the same time. I just got a set from Chad at RedBarn. Can't wait to use em.

    Morningstar!

    the guy who makes them is super cool, and they are a bargain considering what you get for your money. Great instructions too. And don't be surprised if he gives you a call after the purchase to ask how they are working for you!



    p.s. I clamp a small metal ruler to my stays as a guide.

    Thanks for all the responses. I think I'll have to grab a set of those Morningstar tools, those look like the ducks nuts.

    CC, I came to the same realization about over bending the stainless while riding earlier. Too bad I did think of it earlier before posting.

    Just go and...

    ... get a new one! You'll never get it back to where it should be! I bet those tools cost more than a rotor. Are you in some godforsaken place that you can't get a rotor?

    Depending on the truing stand you have (if you have one) you can use it to true your rotors too. Along the same lines as the ruler on the stays trick...

    I mount a dial indicator with a magnetic base to the side of my truing stand. Saves a lot of trial and error, eyeballing and guessing. Accurate to .001".

    ...ahhh, just noticed the one in the Morningstar pic. nice.

    Because bling ain't cheap:



    Also I can and have dinged my rotors several times in a season. Even XT rotors are ~$30 bucks each... I can't toss em like tubes.
