y didnt you just run the first cut there is no need to put the straight edge under the silver and snap it the way you did just a waste of time

How thick is the mirror? and is the "cutting score" over the centre of the blue straight edge?

I've got to cut, several 2200mm long x 750mm wide x 3 or 4mmmm thick down to 2000mm long. I'll have to cut them on the floor, could I use my 1/8" thick x 36" long steel ruler in place of your blue straight edge?

If not what's best?

@bigian279

it is 1/4"inch mirror. you need a striaght edge a little longer than the mirror. you can not start and stop your cut, the mirror will run out on you.

@myglasstrades Thanks , can I use my 1/8" thick x 36" long steel ruler in place of your blue straight edge? Where do I place the scoreline in relation to the centre of the straight edge?

THe finer the grit the better on a belt sander. you get a much better edge.

I like an older used 400 grit, almost smooth.

Mike - what grit sand paper should be used and can I use my hand orbital sander? Thanks

How do you cut old glass? I can cut up to 24" but cannot do anything larger. I am trying for 23x39" but have consistantly wound up with many much smaller pieces.

What about wearing safety googles, especially when you use the belt sander?

Thanks so much for this video!

@LSUTigerMom . We really dont use them too much. It makes it much harder to see the edgework that you are producing. You can if you like but experienced glaziers wouldnt use them in this situation.

There are things that we do use them for, but this is not one of them
