How to modify a grinding wheel AND MORE!

How to modify and dress grinding wheels.
In depth discussion on several styles of grinding wheels including different abrasives and different wheel shapes. Some safety tips. Also some wheel setup and speed information.

I'm new to T/C grinders etc. watched a few youtube videos, recently bought a used KO Lee 360, done some T/C projects myself. You've got some nice equipment there and seem to know how to use it. For dressing diamond wheels, have a look at Alfred Lyon's videos, in one he shows a Norton brake dresser for dressing diamond wheels. I made one myself from a chunk of aluminum, a couple bearings etc. seems to work but slower than a diamond on A/O.

Thanks for the comment. I'll check his video out.

Hi from Australia :)
Thank you - I really like how you succinctly explain stuff. Your videos would be great additions for any engineering students. Stay safe and well.

I appreciate your comment. Thanks for watching! More to come. Cheers

I taught metal shop for many years, and found your presentation to be excellent. W/O research as I recall, the grit number is based on the wire mesh through which the abrasive was sifted. By that train of thought, a mesh of 14 wire threads sifted the particles. Hence, the thickness of the wire reduces the size of the particles that can pass. This means that theoretical spherical shapes would be significantly smaller than what you described. However, in real life the wire mesh presents a square w/ a diagonal which mostly validates your claim. There's even a joker... imagining a rod shaped particle of unusual length... as it would pass the screen and confuse the issue. Fortunately, this happenes infrequently and is therefore disregarded. Still, in theory this unlikely hood could gouge into your work to marr it. In reality such an unstable piece of grit is more apt to break than do such damage. In short, your depiction would be near perfect if you didn't draw circles but oblong particles all arranged by their longer length across the inch.

Thanks for the comment. After minimal research I've found that there's a lot of different thinking out there. I appreciate you adding to the conversation. CHEERS!

So how fast/slow should a diamond wheel run did you say? I thought they were just a straight swap, which would be why I had no luck with my first attempt with one.

[@Lappemountainliving]

1200 RPM with diamond wheels works well for me.
3000-3500 works well with my aluminum oxide wheels.
In both cases I'm talking about wheels 4"-6" diameter
