Hubby finally got the 120 grit diamond for the cr*p Top-Superabrasives wheel he bought so he made this short video on what was involved. We don't see a lot of folks doing the low grits under 280 so we thought we could give a couple of tips. 1. When using lower grits, don't mix the grit into the epoxy before brushing it on, use the epoxy first and sprinkle grit by hand second, method. 2. Big grit gets pulled off the wheel easily if there is not a lot of it there and at least 1 good coat of epoxy is not covering it. 3. If you buy a low cost, low grit wheel and you really can't see any grit in the epoxy, chances are it isn't there. Also the foreign sellers seem to sell 8,000 and 12,000 grit wheels and label them 140 and 60 grit. (I don't know if they do it on purpose or if they are just stupid, but it has happened to me.) To make a long story short, it now should act like 120 grit instead of 12,000 grit. Just so you know, he shot the video with one hand while the other did the action. It's a little shall we say, non oscar winning stuff Youtube was acting up when we posted this so if it doesn't play, try later.

Just an update on the 120 grit re grit. Below is a photo of the wheel after about 100 cabs of varying hardness.

I missed this until you bumped it. That's pretty slick! easy peasy especially if the guy doing all the work could get the SOMEONE to hold the camera! So the wheel is working well for you now - right?

That's cool. I have this to do on my err... new okay okay, used Nova wheels. I had saved a link from somewhere before but this helps. One thing that I can think of to improve the process (other than a tripod for the camera) would be to use a fine sieve for the diamond; for fine grades I might try an enamel sieve. Thanks
