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
When rotating this will be a 10 element ,1/2 diameter pure tungsten
electrode spark gap.
Mounting the G10 to the shaft,,I have looked at hundreds
of pulleys,,faceplates,,mandrells,untill I no longer know what to
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
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,
Re: Help from someone smarter than me
I assume you are going to fabricate your own 20" x 5/8" FR4 disc.
To attach the disc to the 3/4" (keyed ?) motor shaft you will require
a suitable flange eg. ABSSAC Sure-Flex type J flange as in their
catalog (page 63)
This will need to be bolted to the FR4 disc and balanced.
I suggest you contact them and find out who their agents/distributors
are in your part of the world..
