Diamond plates from asia
Has anyone tried these thin 1-2mm diamond plates from ebay/aliexpress and used them long term?
Small 80 3000 Grain Size Large 240 800 Grain Diamond Chip Whetstone Sharpener Kitchen Sharpener Tool Sharpener Garden Sharpener|Sharpeners| - AliExpress
Are they flat and remain flat?
I just bought 400/800/1500 and plan to epoxy them to some quarter sawn vic ash about 30mm thick - you think that the timber will be stable enough?

Paul Sellars did a write up awhile back on this type, he's found them perfectly serviceable. Edge Sharpening Under PS10 - Paul Sellers' Blog

I purchased a set (grits up to #3,000) a year or so ago. I figured at that price I could throw them away. Same as the Peter Seller's ones going by the labels that he included in his blog.
Anyway, no complaints, so far.
I mainly use the #600 at the lathe to touch up straight edges tools before reworking on the #360 CBN grinding wheel.
Actually, I got two sets so I could keep one lot unmounted to sharpen difficult to get at edges like on router and Forstener bits. The thin profile is ideal for getting into those edges.
All diamond and CBN abrasive plates and wheels lose their initial aggression. These don't seem to be doing that all that much faster than any of the other half dozen more expensive ones that I own. And, if they did, they are still very good value per sharpening stroke!
Derek Cohen has also posted about these thin economy plates some time ago on this forum.Stay sharp and stay safe!

What did you stick yours down to? Im questioning if vic ash is a good idea - I looked at some of my 19mm quarter sawn boards and theres a bit of warp in them. I dont have any plywood.

You could superglue then to aluminium plate or thick glass.
When you want to replace, just heat and the glue will fail.
