shaft fasteners for RSG?

Hi all,

I have started getting the urge to build a big coil again and
I was wanting to do everything right this time. In the past,
I simply used a bench grinder motor with the emory wheels
removed and replaced with a lexan disc(s). I used the ex-
isting emory wheel arbor to secure the lexan disc but I
want to use better hardware this time around. I've noticed
that most of the professional built RSGs have a sleeve or
bushing cylinder that appears to go over the shaft with
set screws to secure it to the shaft and about 4 set screws
that secure the disc to the sleeve bushing. Home Depot
and Lowes don't carry anything like this and I was won-
dering where to get this type of shaft hardware (McMaster-
Carr, I assume) and what name would it be listed under?
I know that you can get G-10 sheets at McMaster-Carr
also, but I found that I could also get G-10 at one of my
local plastic suppliers for about 60% of McMaster-Carr's
price.

Thanks,
David
