Hi - Just bought a Jet 1642EVS lathe. Love the thing, but am concerned with how hot the phase inverter on the back of the pully housing gets in operation. A chip got lodged in the heat sink last night that didn't produce flame but did smoke and cinder pretty good. I've rigged up an "ad hoc" cover for the inverter, but this whole thing looks like a serious design flaw to me - anyone else experience this with this lathe or something like it?
