Surface Grinder Wheel Balancing Fixture

[Janderso]

Pinch me, I did it right!
For three days now I’ve been struggling with how to cut the taper. Part of that time was to determine the angle I was to cut.
I have a B&S Micromaster surface grinder. I found a schematic that showed the taper at 3” per foot.
I deduced this to be a 7.125 degree angle.
I made a jig to set up the compound.
I cut the taper to hold a wheel adapter for the balancing fixture, yet to be built. This is the hard part, the rest is easy for me.
I could not be more pleased. The adapters lock up perfectly.
This is big boy stuff!
Now I can finish the arbor by threading for the locking nut.

Ca-Lem is. my inspiration.

Edit, I should add, the random holes in the angle tool was my failed attempt to use my mill dro to cut the tool. I failed to consider the cutter radius and made a big mess of it.
I used my Jo Jo blocks and my compound sine to set the angle and ground it in on the SG.
Oh, first time to turn between centers = slick as can be, simple to set up too.
I’m telling you, this is adult entertainment. For me anyway.

I recently made one too. So glad I did because I had a couple of wheels that were way off.

Dang man, that’s artwork right there.
I like your rail, simple too.
The challenges of understanding which wheel to use, depth, feed rate, when to dress, which coolant etc has made me realize it’s no accident when it’s done right.
I have no experience so I don’t know if today’s wheels are of inferior quality or if it’s always been like this, but most are out of balance right out of the box.
Rather than spending a bunch of money for adapters that have the sliding weights, I am choosing to balance them by removing material.
This tool will enable me to do it.
It’s good enough for Suburban Tools, it’s good enough for me.

Have you watched Solid Rock on Youtube? He has some really good tips.

I am still a novice too when it comes to grinding. I figured if I can get the wheels balanced, pick the right wheel for the job, use a tight machine, then that helps to reduce a lot of issues. And then it is basically up to me to get the finish I am looking for.

How did you cut/shape the base? You must have a CNC mill?

Here is a link to his build on his Youtube channel. Shameless plug for Tom,

Nope I am a manual guy. Milled it by hand to close shape and then let the belt sander do the final touches.
