I bought a Shars diamond wheel for my surface grinder. As many of you have discovered, the texture has facets that need to be trued/cleaned up.
This is my progress so far.
The bearings fit well. One is a slight press fit, the other is a nice snug fit.
The spindle is my project for tomorrow.

Any thought to putting some type of drag on the spindle. Maybe a brass slug with a spring and set screw? Idk just have had this on my project list and from what I’ve read and seen your wheel should not spin the same speed as your grinder wheel. I have seen ones where it’s a wheel that is mounted 45* to the base and I believe is presented to the grinding wheel at a 45? Idk haven’t used. Looks good though!
 
Did you nickel coat that thing? Looks like it was coated.
 
I'm trying to figure out what this is for.
Is the grinding wheel in the third picture to dress the diamond wheel?
And the round fixture is to hold said wheel?

Its used for truing/dressing a diamond wheel on the surface grinder kinda like you do with a diamond on an oxide wheel.... Norton makes one but they are expensive I was lucky to get one on fleebay for $40....

I like this project....
 
David,
This should help.
Regarding drag, I have considered it. I have a wheel handle on the other end.
Ca Lem made one of these, he just turned the grinding wheel by hand to introduce a fresh surface.
It wouldn’t be too tough to add some friction.
What materials would be used to rub together that would facilitate a durable wear surface?
Oiled bronze bushing against a polished steel surface? Spring loaded.
What are your thoughts?

The hand wheel is in this pic.

Come to think of it. I don’t know how I would dress this wheel??
They are super cheap. I bought this one on Travers clearance. I think it was less than $5.
 
I’m at a stopping point.
I either finish this by adding the handwheel and placing the device at a 45 degree angle to the diamond wheel.
Or, design a brake.
I vote for adding a break.
The pics show where I am.
I think I got lucky. Using 4140 I turned the shaft to a .0006” interference fit For the 17mm I’d bearings.
The shaft measures .6698“ consistently. I got lucky.
The bearing is .6692” (17mm)

I don’t use Fusion 360, I use Confusion 365.

It seems any time I take a pic on a blue shop paper towel the steel comes out with this color finish??
It is kind of cool.
