Greetings:
I need to mount a 20 inch diameter by 5/8 thick G10/FR4 disk,, (this is a high impact,fire retardent,high Rockwell hardness product)
I need to mount this to a 3/4 HP electric motor with a 3/4" diameter shaft.
When rotating this will be a 10 element ,1/2 diameter pure tungsten electrode spark gap.
My Problem: Mounting the G10 to the shaft,,I have looked at hundreds of pulleys,,faceplates,,mandrells,untill I no longer know what to search for.
When all is assembeled it will be dynamically ballanced of course, I can do this myself,,,I am begining to think a machine shop will be my only hope for building this (faceplate?) assembly.
I was hopeing someone might know of a ready made 8-9"diameter disk with a 3/4" center hole, that I could purchase, Respectfully joesmith
