Compressors - kinda on topic !
I may have a similar problem with my small lathe. It quit yesterday. Had a
couple slow starts where I pushed it with the collet closer handle to get it
going, and now nothing. The fact that its nothing "not even a hum" mkes me
wonder of the on/direction switch is bad. Fortunately I had radiused just
enough alignment pins for the projects that were finishing yesterday.
