Those of you who know me know I rarely if ever advertise here. I just got bumped to "Maximum Discount" level with Diamond Pacific. It doesn't affect most products but I am able to lower my prices on Galaxy and Nova wheels and have just added them to my website on sale at 30% off on Novas and just over 25% on Galaxy. RTH members will get 30% off on either if you let me know. I won't be able to offer any additional discounts to members. Sale will run through Summer at least. Thanks.

Wow, that's great. I was just looking at 80 grit galaxy wheels last night.

Thanks John for the quick shipping. I only thought the wheels were in good shape on my used Genie. Man, that new 280 is going to cut my grinding time in half.

John thanks for extending this offer to us! To be clear, are the prices on your website are reflecting the 30% already taken off for the novas? i haven't bought them before so I'm not sure what the regular price is to compare.

Regular price for Novas in the Kingsley North Catalog are $94.00 for 6", and $155.00 for 8". Other catalogs may very some on price. Hope that helps you. Don

Kingsley dropped their DP wheels to 28% on Novas, 25% on Galaxy so I put mine at 30% and 28%. RTH gets 30% off either. If you order online be sure to let me know you are RTH so I can price it for you. Shipping is generally less than the web calculates and I correct that as necessary when I process the order. As far as prices, 6" Nova wheels list for $130, 30% off is $91. The Galaxy wheels vary by grit but most common are 80 grit $200 list ($140) and 220 for $140 ($98) for 6". Diamond Pacific Galaxy wheels are not the lowest price but are the best plated wheels I've used. The Nova wheels will outlast the Chinese "Soft Wheels" by at least twice.

I have a 8" cabber now. I am new to all of this and still have a lot to learn, so I'd like to ask a question about these diamond wheels to help plan what I'd like to purchase. As I understand it, diamond mesh is not equivalent to SiC mesh in terms of particle size... 600 diamond is not the same as 600 SiC. With SiC, I typically use a grinding wheel around 80-100ish, 220, 400, 600, then to a polish. I wouldn't mind adding another step between the 600 and the polish, as my new cabber can hold 4 wheels and uses a polish disc on the end.
What would be a good sequence of 4 wheels to use in Diamond meshes for cabbing? I haven't been able to find a very good comparison writeup between the two. I'm sure the galaxy vs nova thing is common knowledge, but I haven't had the opportunity to use or even examine either side by side where I live. The prices of the 600 galaxy is pretty close to the 600 nova, but I'm not sure what the performance differences will be.
Also, I see the expensive 60 hex galaxy. What is the typical use of this? Ultra-fast grinding of sphere preforms and other non-cabbing heavy duty grinding? Is this something that would ever really be used in a cabbing setting?
What speeds do these wheels like? All 4 wheels will be run on the same shaft, so if there are different speeds needed I might need to modify the plan. Not sure why it would matter, but I've been surprised by things I didn't consider in the past. Wondering if a diamond wheel conversion from SiC wheels will require/benefit from a change in RPM.
Thanks in advance for anything you guys/gals feel like teaching me on this thread before I buy!

Your unit likely has a multigroove pulley so you can adjust speed. 1725 will work great. The Galaxy wheels are plated (hard surface) wheels so better in 80 and 220 range. I have commercial cutters that use 600 hard wheels for longer life but it takes practice to avoid flat spots. The Nova wheels are foam backed (soft surface) wheels so better for sanding, prepolsh, polish range. All Diamond Pacific machines use 80 and 220 Galaxy and 280, 600, 1200 and 3000 Nova wheels. That sequence works very well. If you want four wheels between your bearings (won't be easy to change) I'd probably go all Galaxy 80, 220, 360, 600. You likely have a split drum sander which I would replace with an expando drum and use diamond belts for 1200, 3000,etc.
The hex wheels are real aggressive and used for fast material removal. The cutters I know that use them finish with standard 80 and 220 grit to finish their shape.

John, I'm looking at the Eastwind diamond belts on your site. For a guy used to the SiC belts cost, a $65 belt sounds quite painful to me. I'd honestly find it easier to stomach the cost of a nova wheel at slightly more than the cost of 2 belts. Will I get about the life of a Nova wheel out of 2.5 of those belts? If that's the case, the expando drum w/belts sounds like a good idea... but if I'm going to be going through more than 3 or so belts to equal the life of a nova wheel, it's hard to justify the belts over the wheels. One of the wheel mounting spots on my cabber is on the end of the shaft, so it wouldn't be terribly hard to swap out wheels if the belts last significantly less.
Sorry I have so many questions, just wanting to make sure I know exactly what I need before I start investing in the diamond hardware... thanks so much for your advice as I plan this. Also, if you'd prefer I start a new thread so yours doesnt end up hijacked with questions about my specific situation let me know... I figure there might be people with the same questions looking at your post that might benefit.

How long something lasts is really up to users. I commonly hear commercial cutters say 6 months for an Eastwind belt (really fine grits more, sometimes much more). Most commonly hear 1 year to 3 years for Novas. Compared to wet and dry belts where life is measured in number of stones cut. Of course then you hear from Bobby here that gets years out of his SC belts. One of my regulars will only use Eastwind belts but gets careless and tears them long before they are worn out. I wiped out a Nova pressing a BO into it for a few minutes. Which lasts longer would depend on how heavy handed you are. I think one drum and a stack of belts would cost much less than a stack of Nova wheels.

My Genie, purchased new in 94, still has the original wheels on it, They still cut good, but I suspect the hard wheels will need to be replaced in the near future. The wheels will last in direct contrast to the user. If you're heavy handed, expect to replace them every couple of years. If however you use a light touch, as I do, they will last many years. Don

Don, the commercial cutters I mentioned cut 8-10 hours a day. Most have switched to sintered wheels for grinding. I bet all would love to find something that lasts 15 plus years.

I doubt if my next set will last that long. Nothing is made as good now as it was back then. Don

Just going over this thread as I will be asking these same questions sooner or later ...Besides for the obvious and digging a sharp edge into a belt , What other mishaps could tear the belt ?? pushing too hard ,etc ,etc ...Also what are some common mistakes newbies make that could destroy a wheel ? The last thing I wanna do is make those !!! Greg
