I used a 4" grinder with a medium metal wheel to clean up the epoxy bugers off the last couple right BEFORE i trashed out another bandsaw blade...i thought i had the solution using 3 TPI bi-metal blade....oh it worked great! but thats all its good for now...i should have just stayed whith the grinding wheel..after that $40 dollar blade wont do it anymore, i'm going to start free handing them on the table saw with a carbide blade.....get them within an 1/8th inch and grind her in from there....i've trashed out a bunch of them on this glass, and the epoxy isn't very nice to blades either.....
