Hi everyone
It's been a minute since I have posted anything. I missed y'all.
My delema, I have a rogue diamond on my 3000 diamond wheel. When I hit it it ruins the hard work i had previously done on a rock. My question is there anything shy of buying another that I can do. Its about an inch off the Arbor. Does anyone have any ideas.
DIAMONDS ARE NOT A GIRLS BEST FRIEND!!! GRRRR

Maybe run a hard piece of jasper across the wheel and apply some pressure

“About an inch off the arbor” sounds like you have a flat lap.
Can you find the culprit with a loupe and chip or scrape it off?

...don't run the cab over that spot...
If running a hard agate or jasper over the spot doesn't dislodge it, I'd be doing what Rich suggested and taking a good look at it with a loupe to try and find the dirty little bastard!
If worse comes to worse and you can't find it, I was kind of serious about the first suggestion. If you have an "idea" of where it's at, then there's a lot more area on the disk that can be used...unless you're face polishing a slab...then you might still run into it. (Just thought of that when I was typing! LOL)

I also was going to suggest the same as parfive. If that doesn’t work I would seriously put a blob of paint or sharpie marker over it so that you see the stripe of color as the disk turns and can avoid the area. At least you should be able to get more life out of the disk.

Have you tried scrubbing it with a brush and plenty of soap and water?

First find exactly where that bugger is. You already have a good idea of that. Take a piece of agate and run the lap on the slowest speed you can (use a slow water drip). You should be able to hear it "tic" when it goes over that spot. Mark the spot with a Sharpie. Get a straight edge razor blade and run it over that spot almost parallel to the lap. Be careful to not gouge your lap! Also make sure you have some water on there. Hopefully that will pull it out. If it does, take the lap off the machine and scrub and rinse it really good with soap and water. Also clean your machine really good to make sure you get rid of it. It could recontaminate a lap. If it doesn't come out, do what khara suggested and use the Sharpie to make a ring around the lap and avoid that area. Good luck! |

If all else fails (all the above suggestions would be my first goto) try a dressing stick. I'm guessing it really isn't a rouge diamond, rather a clump of diamonds that are bumped up (either a clump of epoxy, or something got under the pad). Either way I hope you can salvage it

Good luck! Seriously, I would start with a good wash and stiff brush. Then I would try stefan 's suggestion of a dressing stick. I bet that would do it. I use them a lot. They can really spruce up the diamonds. |

Kelly Basically they're aluminum oxide sticks that are used for "sharpening up" diamond saw blades, wheels and laps. cuttingedgesupply.store/collections/dressing-sticksDo not use a dressing stick if your laps are resin diamond laps. It will ruin them. |

It will ruin them. Thank you. If they are white I think there is one in my panther saw. I will look at the website and see what they are. I thought I had it and I was using it with one of the stones I just posted. Nope it's still there or it's brother showed up. |
