This is an issue that drives me nuts.. I use diamond stones mostly for sharpening chisels, plane irons, etc., but something I've noticed is I can purchase a 6" x 2" stone for about $6 give or take a few bucks, but move up to an 8" stone and the price goes up almost exponentially to somewhere around $60-80. Has anyone figured out how that can be? Is the extra 2" THAT much more expensive to produce?
Anyway, I found what appears to be a decent deal, http://www.ebay.com/itm/131925265510
They're thin pieces NOT attached to solid blocks, but some epoxy could solve the problem I would think.
Awhile ago I purchased a 6x2 stone, 120 one side and 400 on the other side, but the diamond plate portion came off the inside block so I slapped it back together with epoxy and have had zero problems with it since.
What I'm planning is to purchase the thin diamond deals from an ebay seller and slap them to perhaps bits of tile from one of the box stores and see how it works out.
The dimensions of the new diamond plates are 170mm x 75mm, not quite 8 inches, but still larger than 6x2.
For about $7-15 this appears to be a pretty decent deal, but time will tell.
Has anyone else tried to do this?
I've searched and searched for diamond stones bigger than 6x2 for lower prices, but just about anything larger than 6x2 jumps way up in price.
I have about $50 invested in 6 different grits from 120 up to 3000.. I'll keep you posted on how it works out..
