Topic tags/keywords: resource tip question 8 grinder sharpening

Hey Lj’s!

Went to do a quick sharpening of my carpenter Stanley work chisels. Pulled out my 8 inch Porter Cable variable speed grinder.

I had purchased a Norton white wheel for finer grinds and I have one that came with the grinder. Set it on a very smooth surface and it started dancing with vibration. Put a pad under it and started it up.

I had read that you can shim the stones to get them in balance. The white Norton stone as I measured the run out was 1/16th plus out of true

I know there is wisdom here and experience that can help me correct this issue.

What is the best and safest way to reduce the wobble in the stone? I read somewhere that I “should not attempt to flatten the sides of the wheel.”

Your suggestions are appreciated.

What rpm are you running it?

I’ve run it to around the middle range with the least amount of vibration. Don’t know exact rpm.

Dress the wheel. Rotate the wheel to help balance it. Also if you have a lathe turn yourself a bushing or see if you hardware store has a solid bushing for the wheel. You can also order a solid aluminum one from wood turners catalog.

Thanks!

Dress only the face? The wobble seems only in a quarter of the wheel? I’ll have to check, and I’ve read that the stone can be fractured by replacing the bushing with something harder?

I have a lathe but I need the grinder to sharpen my new gouges? LOL!

Put an index mark on the shaft, then 8 equidistant marks around the wheel on the label (past the edge of the large washer) then test rotate, test,...

Oh, I also sanded the washer so it was flat where it met the wheel to get more contact.

I was pleased at how well this worked.

I did turn a walnut bushing and it was a vast improvement over the plastic
supplied one.

Tom, you may want to put your hand in your pocket and get one of these (link below). A while ago I saw a video and it should do the job. And it will last for ever on the same grinding wheel.

From my experience it will get you on track not sure on the balancing part though.

Serge,

THANK YOU!

Watched Tim Yoder set up the grinder. Need to shim both sides of wheel. Didn’t see that in my searches , just said shim. Some suggest turning your own sleeve, but I’ve not started turning as I wanted to make sure I had an edge that would cut on the tools I have.

Saw a steel sleeve on amazon which I’m going to purchase. Not expensive.

I want to get started before I think about spending more money.

Thanks for thinking about me!

Tom
