That 8-foot tempered glass panel in the stairwell took me a whole afternoon to get right

The client wanted it flush with no visible clips, so we had to custom grind the edges on site. My usual diamond wheel kept chipping the corners, and I went through three before switching to a slower speed. What should have been a two-hour install turned into six, mostly because I was too stubborn to call for a pre-polished piece. Anyone have a better method for field edge work on tempered?

What grit were you running on that diamond wheel? I've found a 220 resin bond can handle tempered edges without chipping if you keep it flooded. Did you try a continuous water feed or just a spray bottle?

My old 120 grit wheel always left a faint chatter pattern on the final polish. For your 220 resin setup, what's your actual coolant flow rate? I'm trying to figure out if my pump is pushing enough volume or just making a wet mess.

Honestly I was stuck on 120 grit for years, thought it was the only way to get a fast grind. But I tried a 220 resin wheel like you mentioned, with a real flood coolant setup, not just a spray. The difference on a tempered steel chef's knife was night and day. No micro-chipping at all, just a clean bevel. Totally changed how I set up my shop now.
