Hi Jeff, Thank you for your post. Just to clear up the concerns, I did not say I had a new supplier, I may have said new shipment from the supplier. I would not sacrifice quality for something that is less expensive to procure. We have been selling our CBN wheels for more than a year now, we have had two returns for wobble, I am sorry that yours was one. I specify the hole diameter to be -0.000" to +0.0015" and they are measured here before we ship them. I am still not sure why the wheel wobbled on your grinder because we could not reproduce it here, but I am glad that it worked out for you. We are now manufacturing them with a direct bore, but on your older style with bushings, the bushings were made locally here in NY to our specifications.
