I would love to see what you had in mind for your belt drive setup. If you find those files i would enjoy looking them over. BTW, I never throw out files, I have cad files from 2001 in my pile of designs which is vast and very disorganized. I tend to look for a file to get back on a project and i always have a hard time figuring out which one is the most up to date. hahah
Kurt, the data plate on my mill states it was mfg 2012 so its not exactly a new mill or anything. I sure wish my shaft was 7/8" and motor mounting was the 145TC style but its not. a 3/4" shaft would work but there are no motors with such a shaft diameter that i can find. I thought maybe i could come across a 5/8" shaft motor and make an adapter but, I would rather not get into all that. If i swap motors I will just get a VFD and inverter duty 3phase motor which you can find on ebay for a reasonable price but again nothing out there matches which my machine needs for mounting. I guess I could make a new adapter ring that lifts the motor up and use a shaft adapter if they make one for 7/8 to 3/4 keyed shafts. I am not in a rush for a motor swap as this thing slings chips just fine for now.
