Hello everybody, new comer to forum, looks good so far! anyway I have a question, wanted to see what you all think. We have a hollow chisel morticer by Grizzly in our shop here at Indiana University in South Bend. When running with no load, it chirps or skreech quite loudly, doesn't seem to matter which chisel set I use, when cutting all that stops, and it works pretty well. I was thinking about spraying some sillicone lube between the bit and the chisel to stop the noise. Good idea or not? If the noise isn't hurting anything I'll forget it.
