Decided to rewrite my post about gluing stones to glass. The old one was a year ago here: http://www.kitchenknifeforums.com/showthread.php/26849-My-new-Shapton-Pro-Glass-Stones
The idea is to make a stone thicker, heavier, more stable and less prone to warping. You could use the stone up to the last 1mm of thickness left (hopefully!). The matte glass also helps to flatten other stones.
4 pieces of 4mm sandblasted glass (one side gloss, one side matte) in 210x70mm cost me $15. The glue I'm using is Henckels Moment 100% which is a sort of rubbery transparent glue. I think epoxy also works, I did one with bathroom clear silicone sealant with OK results.
The edges of the glass were sharp at first so I rounded and smoothed them on a diamond plate. The fine ones work very nicely, coarse ones chip the glass too much.
Rounded the Shapton Pro corners too.
Taped up the stone on all sides but one. Taped the matte side of the glass with transparent tape (to see where and how the glue is spreading).
This is the suggested shape of the glue before squeezing the materials together to help it spread better. The tricky parts are the far corners, hence the X shape.
The glass on, slowly starts to spread. Put some pressure on it but don't rush it. Some of the glue will absorb into the stone which will take a minute. Coarser stones absorb more.
Little clamps come in handy, as do gloves, wipes and some solvent. Note the flowing glue on the edges, just keep wiping it off and realigning the glass (it slides around easily until the glue starts to set). Once no more glue seeps out, I cleaned the glass edges with solvent and left to dry.
Finished stone!
This Shapton Pro has been my go to stone for some time now. I've got the 320, 1000, 5000 and 12000. Mostly only do a 2min sharpening, 1min on 1k and 1min on the 5k for my gyuto.
I hope this post helps someone! Happy honing!
