In the interest of keeping the neighbours sweet I am wondering how best to reduce the humming noise from my mill and lathe, both of which have cabinet mounted single-phase motors. Both have the motor bolted to large steel plates with a pivot at one end which is in turn bolted to the stand. I have another lathe with external single phase motor and that is fairly quiet.
I am assuming that most of the noise is through mechanical transmission to the sides of the cabinet which act like speakers, so I was thinking of rubber mounting the motor on the plate or maybe using metalastic bushes in the pivot point - and some other sort of isolation for the adjuster on the other side of the plate.
Alternatively (or in addition) I could try and damp the movement of the panels.
If anyone has been down this road and has some advice, then I would be interested to hear.
Thanks Steve
