The spindle motor blew out on my mill (Novakon NM-145) and I am looking to replace the motor with a 3 phase ac motor but i will need a mount fabricated. it would start out being maybe a 5/8 (maybe 3/4) plate 6" x 14" (rough estimate). it will need 6 clearance holes for the bolts and holes for mounting the motor. the motor would be a 56-c mount. your choice for material although i think aluminum would be better than say cast iron and if your +- .010 on the features you will be closer than the stock cover plate. ill get a detail drawing up later today. im just putting out the feelers right now.
here is a pdf of the part i would need. many of the dimensions can have even looser tolerances if need be. it looks like i forgot to add a depth to the 4.5" feature. it should be .16 deep
