Trimming a ground glass?

[Drew Wiley]

The trick with a belt sander is to use black silicon carbide belts, the kind actually distributed thru glass outlets. 3M makes them. Otherwise use a sanding block with fine
black emery cloth tightly attached to it. Sorry Steve - I thought it was you Brits who didn't know what power tools are. So I won't say exactly how I trim down a groundglass,
because I have certain, uh, logistical advantages, like a forty-page list of German power
tools warehoused fifteen feet behind my desk.

Take it to a glass shop and have them use their wet belt and do it properly!!!!!!!!!!!!!!!!!!

Great suggestion from Ken, above, and...don't forget stained glass artisans.
They have all the 'right' tools, and the expertise for finite trimming of glass.

I also recommend taking it to a glass shop and have them grind it to size. I had the same problem a few years ago, and took the glass and the camera back to a local glass shop. They ground it to size in a couple of minutes, and didn't charge me a cent.

Not just Americans... but Normies too (in the woodworking meaning of this term)!

That's exactly who I was thinking of. he can't even put in a nail without a specialised powered tool!

What Steve said; I'd recommend 100 grit, and tape the other edges to save your hands. Sand cross-ways to the glass, not in-line, with light pressure, take your time.

Another one for this solution.
Quick and easy. 1/32 maybe 10-15 minutes. Faster than a trip to the glass shop.
Tape the edges you're holding though, wouldn't want to get blood on the glass.

Tape the edges you're holding though, wouldn't want to get blood on the glass.

Whilst you're at it, round off all the other edges so there is no chance of ever cutting yourself on it.

And while one is at it, one might as well make sure that all edges of the GG are smoothed. Less likely to break and easier to handle.

Whoops! What he said up there!

$20 for the ground glass. $750 for the trip to the emergency room. 6 weeks of trying to do LF movements with one hand...

$750 for the trip to the emergency room.

Do it in England. It's free!
