Hand grinding/shaping tungsten carbide on an 8" bench grinder?

[Scottl]

Going to a too-fine-grit diamond wheel can jeopardize the cost efficiency of using diamond wheels. A 120-grit wheel run wet can be the lower-cost method and gives an Ok finish for such as flats and tickling boring bar ODs.
At first use, it is best to indicate the wheel OD to .002 or better so at the end of life, you don't run out of diamond on one side.

A simple aquarium pump can be attached to a bench grinder setting in a homemade plastic tub for a mock Tc grinder... you might even consider attaching a bargain tilt table.

And hand lapping just the very edge with a finer grit diamond paddle will give a better finish on the work. We were taught in school to always hone the edge of tool steel lathe bits for best finish.

You want us all to come over and watch you sharpen endmills for a while, so we can give you a score ?

They're on your grinder, how about you tell us ?

Well, I don't sharpen endmills with my cutter grinder. Just simple stuff like necking cutters and putting putting flats on shanks generally. I do hope to do more with it, at least start to sharpen straight edge chamfer cutters and similar. The chicom wheels do work and are cheap but I don't have a lot of experience to compare them to.

ah don't care if it rains or freezes
long as ah got mah chicom jesus
on the workbed
of mah grinder ...



I could maybe find you a cap to wear while grinding, if you want. Help to get into the spirit of the thing

I visited the 9-mile road shop where GE/Carbloy was experimenting with manufactured diamonds. There was a rumor that they had to make a deal /Agreement with Debeers to be able to market MFG diamonds.

I can assure you that this was not a rumor.

One fellow I knew got shotgun shot at 16 years old and had pellets that He could feel at over 90 years old...

Amazing that he survived that.

I remember many years ago talking with a guy who worked as a Chicago police force beat cop. Told me that he didn't care that much about handguns, because most people he encountered couldn't hit anything that was farther than a stones throw. The thing that scared him was shotguns: if someone pointed one of those in his direction, he'd just do what they said, no questions.

lucky not to damage any vitals.. but it was likely rabbit shot and did not hit an artery. Lead in one's stomach is dangerous but lead under the skin or oi meat is not so dangerous.
Carbide embedded in one's body is likely not very dangerous, might be if having sharp edges,,?.

We used to green wheel grind carbide to good sharp edges..but it took a lot more pressure so size holding was tougher..good that diamond wheel prices came way down to make diamond grinding carbide feasible.
