Grinders and grinding wheels your views and ... - Family Woodworking

Ok so i am busy working on a "cart/tabletop" for what is to be my mobile sharpening station. This is long overdue and i came to the conclusion one of the causes of failure in quality and ensuing frustration in my shop and working habits. You gotta be able to access sharpening quickly when you need it not have it be a huge disruption to what you working on at least thats my view now.

In this process i am mounting my grinder on a removable table top insert and one item i would like to have adjustable is my lee valley rest. To do this i am putting in a piece of T track parallel to the grinder.

Now giving thought to the fact that my grinder is an 8 inch i got to thinking with using very friable wheels at what point do you guys change out a wheel.

The point has been made about the arc on an 8 inch wheel being flatter than the arc on a 6 inch wheel so if one is going to buy into this concept and keep to getting consistent grinds one has to decide on a point at which you going to retire a wheel.

So whats your thought on how long to use a wheel till you change it out?

Also whats your configuration on your grinder. I have tried a felt wheel on one side and on the other my 80 grit white norton wheel. But i am skeptical about the felt wheel although my knowledge of sharpening has come a long way since i last had it mounted so maybe i should give it another go.

I did spot a $50 8 inch grinder at Princess Auto a while back that i was also thinking could be an addition to the shop (when i searched for the link i see its now even less) for the more general purpose grinding which when done on an 80 grit wheel tends to mess the wheel up and eat it away. So whats your thought on having two grinders in your shop if you use your shop for more than just woodworking.

Anyone tried using a very thin wheel on a standard grinder. Thinking of the red ones that are used like on a hockey skate sharpening setup.
