finish the edges
after cutting the glass do I need to sand or smooth the edges?
AnswerIt's not necessary unless you have rough edges that need to be smoothed off to make the glass fit right.
There are people that smooth every edge of each piece they cut, and others that don't smooth at all unless absolutely necessary. I'm in the latter group.
You can use a carborundum stone which takes some work to grind down an edge, but it's cheap, or you can buy a grinder, which does quick work but they are expensive.
I have both, but I use the stone much more often than the grinder. I can keep the stone on my work bench so it's always there if I need it. The grinder is on a stand where I have to get up and walk over to it, so it's less convenient.
