Hello
I have a question on the best procedure or tools to use to get the polycarbonate to fit the emmiter, previously I just took the finished blade put it on the bench grinder and sanded it down till it fit. But I also had it break, it was 1/16 Th. though, I am now only using Tim's 1/8" Th. Any suggestions on how to proceed would be appreciated.

May the Force
Be with You
