Now this is one that you need to see about the grooving of the rotors. It's what you were looking for..................

That is it.  How in the heck did you find it?? What did you use for a search?
When you think about all the times you turned your rotors it is kind of scary. To think the times I was broke and just replaced my pads I was much better off safety whys.

I knew what you were looking for..........I was waiting to see if anyone would come up with it. I guess I'm ebo 2 ......(he taught me well).

That's an interesting video.  Will make me think twice about turning rotors next time, but it sounds like turning is still a viable option if all the conditions are met and the grooves are removed with non-directional finishing.  I'd be interested in finding out more about that procedure.  So is that the kind of thing where you bring them home from the shop and then apply that finish yourself with a hand-held random orbital sander?  Or should that be applied with a special machine while still in the lathe fixture?  I'd be worried about screwing them up worse than before.  I'm not asking for my 'Vette, but my wife's Honda Odyssey is starting to pulsate just a little and I was thinking I'd have the front rotors turned for starters.  

I would rather they did it where the rotors were resurfaced.........if they can and are willing to do it.

Depending on the year Honda she has could really make a difference in cut or replace..the older ones had the hubs on the outside and had to press out the bearing to get the rotor off..I would highly suggest some kind of one the car brake lathe..I think its a tool Honda dealers have to have now since all the rotor issues they had..the finish should be done wherever the rotors are cut..

Good to know, Rich!  About what year did they change, do you know?  We have an '07 - the generation started in '05, I think.  

Yeah when I say old I guess I meant the first Gen..like 95!!.. the 07 is a simple set up..they had issues with the hub not being true so on the car became the norm in 01-02..don't get me started on the trans in that car!!!.In the video of the on car lathe it shows the guy using a wizzer wheel to burnish the surface and that works really good..I have access to the bodyshop sand paper cabinet so I use the 40 grit stuff that really works good for a finish..been using the on the car lathe now for at least 10 years and its worked great everytime.

Folks, there's no problem with having your rotors turned on a lathe, whether on-the-car, or on a bench lathe. They've been doing them like that for 100 years(drums & rotors). The main issue is operator skill, and lathe quality. I have an antique Accuturn lathe that will turn a rotor just fine. I do use a sanding disc in a die grinder, and knock the grooves down a bit, while the rotor is still turning on the lathe. Haven't had a problem yet. I have also re-done rotors that we had sent out to a machine shop, because they always seem to have too rough of a cut on them....they get in a hurry, so the final results suffers. That's the operator skills part...not a reflection of having them cut on a lathe...
Don't be askeered to have your rotors turned. If they are within the minimum thickness allowance, as marked on the rotor, turning them is fine. You just need to find a shop that is qualified to do it.

Not to beat a dead horse but here's a rotor I did today on the car..
