Opportunity for 24" Diamond Disks

I'm doing another order of 24" diamond disks.

These are very high quality--I've purchased from this manufacturer twice before. These disks are densely electroplated with diamonds and heavy-duty--much beefier than the ones from His Glassworks. This has pros and cons. The pros are that they will last a long time, are durable and will tolerate some rough handling vs the lighter-weight ones that more easily ding (on the surface or edge). The cons are that they are heavy and the magnets are strong so they require some muscle to get on and off the machine. I cut a V-shaped notch in the magnet and use a butter knife or screwdriver to get under it and pop it off the machine. Olympic Color Rod carried them for a while if you ever used one of their disks.

I currently grind my bottoms with these using a 60 for getting the bottom flat (quickly!) then a 240 to remove the 60 scratches, then go right to 400 (silicon carbide) hand-lap. I don't need any in-between disks. My first 60 lasted 5 years until I felt like it wasn't grinding quickly enough for me. I have over a year on my 240 and it's still excellent. But I like really sharp abrasives because sharp = quick coldworking. (It also means you can quickly screw it up, but so be careful).

Like all diamond abrasives, these require some break-in. I found the 60 crazy rough until it broke in a bit. My 240 was grabby until it broke in (soap, very low water flow, and grinding lots of really big glass helped).

I think the most useful grits would be 60, 100, 220 and 360, so I'm taking orders for these.

These are the same disks I imported years ago as a group order so others here have used them and can comment with their experiences.

I've posted about these disks in "Glassies" on Facebook but realized I should post here too since some of you aren't on FB.

SPECS: All 24" with 1" arbor hole, magnetic backing. Grits offered: 60, 100, 220, 360.

PRICING (each):
#60 - $295
#100 - $295
#220 - $280
#360 - $280

SHIPPING:
Ground shipping costs are as follows based on estimates from FedEx Ground. These disks are heavy-duty so the weight of each one makes a difference:
1 disk - $30
2 disks - $40
3 disks - $50
4 disks - $60
5 disks - $65
6 disks - $70

TIMING: They will take 2 months to arrive (time for manufacturing and ocean freight to San Francisco). I will then pack up each person's order and ship via FedEx Ground.

PAYMENT:
I'm an artist, not a store--please figure out your own invoice from the info above and send payment asap if you want a disk. I can accept paypal, cash or checks.
My Paypal is: paypal.me/davidpatchen

If you need my address for a check, please send me a message through FB messenger, email or through my website form at http://www.davidpatchen.com/contact
and I will get back to you.

TERMS: First paid, first served. If you want disk(s), send me payment and you will be prioritized. Just posting here "David, I'll take a 60 and 220" DOES NOT ensure you get a disk--you don't have an order until I've received your payment. Once I sell out of disks, you're out of luck.

FAQS:
Q: Can you get XX" size too?
A: No, there's a minimum order from the manufacturer for each disk and I'm only doing these four disks at this time.

Q: Can you get #XXX grit?
A: No, I'm only ordering 60, 100, 220 and 360 at this point.

Q: Can I get a 1/2" arbor hole?
A: Probably not, but I can check if you want.

Q: Can I pay you in [insert something other than US dollars]
A: No, unless you have some excellent hand tools to trade.

Q: Do you take credit cards?
A: No

Q: Can you ship them outside the US?
A: I might be able to, but it will probably cost big $$$. Maybe even $$$$ since they're heavy and large.

Q: Can you give yourself a manicure on these disks?
A: Yes, almost instantly. The 60 also removes knuckle skin very well if you slip. Avoid this.

Q: Will these get my bottoms flat?
A: The 60 will (quickly!) or 100 will (not as quickly), but only if you have the skills. Higher grits are really only for scratch removal and pre-polish.

Q: Do they grind clockwise or counterclockwise? Can you use them dry?
A: Please ask this question publicly on Craftweb--I'll enjoy the replies.

I'd like another 60 grit 24 inch dia David. My original really were very nice. A one inch hole would be nice but not critical. It was hard getting through the last one.

well, I looked and even though my current pad is well worn, I find I still have yet another brand new one I ordered from you those years back.

So, I'm good.

For anyone else, these are incomparable pads.
Thanks David.

I will sell the one I'm taking off the machine. It has a lot of life left. 24 inch with a 1.25" center hole. Really sturdy.
fifty bucks.
