Tela you do great cabs. Buy a new wheel and have it over with. I use all sc expands and then diamond on leather. I must luv scratches and flats cause I get lots of them! LOL Maybe I need Nova wheels. LOL! Thanks I have decided to get a wheel. It didn't take toooo long to decide, but now I need to decide which to buy. I hate making decisions.

Tela, the 220 Nova should be close to the 220 Eastwind but it seems to me the Eastwind is a little more aggressive. Downside: it wears out faster and I'll replace it with a Nova. It leaves a finer finish than the 220 Galaxy even though they're the same grit size. I don't know how your eyes are -- mine need a little help these days -- but I STRONGLY recommend using a 10X loupe to check for scratches. When I got into that habit I was gobsmacked by how many remained almost invisible with my 2.75X Optivisor.

Tela: you mentioned that the Nova 280 isn’t performing well at removing the Galaxy 220 scratches .
Isn’t that real hard to tell ? Being that there isn’t big difference between a 220 scratch and a 280 scratch?
It would seem to me if you got rid of all the 80 grit scratches by the G 220 then the main purpose of the N 280 is to further refine the dome shape. In example- smooth out a flat spots. And refine any of the deeper scratches that may be left from the G220.
But exactly what scratches are which are going to be hard to tell between the G220 and the N280.
That where I think Diamond Pacific makes to big a jump. It seems that there should be a N400 wheel after the N280 and before the N600.
Here again none of my analysis is very helpful to you. You work that Genie everyday so know wherefore you speak.
Only other idea I have is ( and you mentioned this) are you using sufficient pressure on the N280 ? Light pressure on the G220 and considerable pressure on the N280.

rockjunquie Tela, I got a great deal ($25.00/wheel) on some new-in-box Nova wheels someone was getting rid of. One of them was a #140grit flex wheel, which normally I never would have purchased. I tried it out yesterday with a wheel combination of: sintered 80, flex 140-280-600-1200-3000-8000-14000. Basically I replaced my sintered 180 with the flex 140. I may never use the sintered wheel again. Coming off the 140 the cabs were already smoother, better shaped, and done so much faster than if I had used the 180 hard wheel and started on the 280 flex. The 140 is very aggressive. It smoothed out the OJ I was working with similar to working a MOHS 6 on the 280. Granted, the wheels are new and cut like a dream. Time will tell me more about how I like them - but right now, I am sold on it. If I need to replace it frequently, I may change my mind quickly lol. One thing I do every couple of months is reverse all my wheels. It seems to help tremendously with keeping them cutting / polishing quickly. If you would like, and if I have time when I get home today, I will take some photographs coming off the #80 and #140 for you. Roger

Roger Hey, Roger- that's very generous of you, but I think I have decided what to do. I am getting a new 280. I would love to go with the 220 soft, but I am worried about taking it to the 600- probably shouldn't be, but 100 dollars is 100 dollars that I don't want to waste. I'm turning all my wheels today as soon as I can get someone to help me move Gene. I just can't stand it anymore.

Hey Tela, Sorry I haven't gotten back to you. The place I suggested, I spoke to Richard. I bought all six wheels new. When I called for pricing, the 280 was $51.00. Don't know if that's where you're going to purchase a new wheel, but you wouldn't be sorry. Let us know what happens............ Deb

Tela, I couldn't find the exact link, so I called them. We just replaced a bunch of wheels at our club house so that's why I knew where to buy them. Good luck, Deb

Resin and diamond Nova Wheels, and Nubond laps, can get glazed over just like plated diamond wheels and diamond blades can. Especially if they have ever been ran a little too dry or with too much pressure being applied. You can dress them again using a piece of 220 grit wet/dry silicon carbide sanding cloth, with LOTS of water running on the wheels, use light pressure with the 220 SC cloth when dressing the wheels. Don't want to use enough pressure to embed any SC grit particles into the wheels. Then flush the wheels with lots of water to remove any loose particles before resuming cabbing. Larry C.

Tela, I agree with what Quailriver said about cutting the glaze with sandpaper. I do that every now & then to expose more diamond if the epoxy has covered them up. I highly recommend re-coating your own wheels. You have an eye for detail. It's not that hard to do. Go for it. Rah, Rah, Rah! I'd post the link to that thread, but I'm sure you've got it bookmarked. It'll save you a ton of money & you will have an new ability. BTW, I'm going to a friend's house tomorrow to re-coat his 300, 600, 1200, & 3000. Once he sees me do it, he'll be able to do it himself.

UPDATE!!! zarguy and QuailRiver Y'all are right and I totally forgot about that. I was too busy stressing. I had cleaned the wheels with a steel brush and dish soap and it worked for a few cabs, but what really worked was flipping my wheels yesterday. I turned them and picked up a bloodstone- being one of the tough ones to polish- I breezed through the cab with no issues what so ever. All the wheels cut beautifully. I am a true believer in turning the wheels. I do believe the other side was glazed. It certainly makes the most amount of sense. The trouble began after doing a stubborn hard chalcedony amy sage which I probably used too much pressure on. Generally, I don't use too much pressure, but on that one I had to keep going through the wheels and I used a lot of pressure. If the wheels were glazed, would flipping them work, as I did? And, will the wheels still be glazed when I flip them again?

Real interesting Tela
never thought that flipping wheels would improve efficiency pretty ignorant about the whole glazing over direction thing
I think you did the right thing getting the 280
sounds like production is up ^ & no rock is to hard

Congrats Tela - I am glad flipping them worked for you and you are back cabbing again I try to flip them every 75/100 cabs or every two'ish months. Quicker if I have been working a lot of hard material or if I notice them cutting slower.

flipping is easy on a Genie I take it ?
The Pixie is a different story although I've never tried it may become easier after a couple times

My son was here just in case my hands couldn't managed the big slip wrench, but I managed. I read the manual and it sounded more difficult than it is. This is my second time.

now oyu got me looking at my Pixie w/ a more critical eye I can see glazing on N600 & up wheels
I might have to tackle taking that machine apart I been putting it off besides I need to buy a G220 & N280

well Tela I'm trying to invent a dial a grit wheel Start at 80 then incrementally turn the dial and the diamonds progressively go off into infinity 1 wheel fits all hmmmmm. How about one very wide wheel, starting at 80 and the more you more to the right, the finer it gets till you're at 3000. 3 inches per grit equals about a 24 to 30 inch wide wheel.
