Hillbilly Tool And Cutter Grinder

[terry_g]

I built this with a 3450 RPM electric motor I bought at a garage sale for $20 and bits and pieces I had lying around the shop.
Its slow but works well.

Looks great. Does it work well?

Hey man, nothing wrong with it if it works! Commercial tool grinders are expensive, that's a good piece of equipment to have.

It works well but its slow.

It works well but its slow.

What's slow about it? Slow to setup, Slow to remove material?

Slow to remove material.

Slow to remove material.

Sounds like the same problem I had with my bench grinder. Ends up I was using the wrong type of wheel for tool grinding.

The white cup wheels are the correct medium for high speed steel.
The grinding surface is fairly narrow so you have to grind very lightly
so as not to wear the wheel.

It'd likely help you to go to a cylindrical wheel as opposed to a cup wheel.. more face to the wheel (same as d bit grinders use).

Inspiring Thanks
Nice build, do you have much end float on that motor?

 

[terry_g]

There is almost no end movement on the shaft.
