Who isn't listening, your not paying attention to what people who support these machine say. Are they easy to use ,no. If it's all you got can it get the job done, yes at least to some degree. Most of use don't have access to the real deal, we have to make do with what we can. That's what these machines are about.

Can you show us images of how you grind four flute end mills with your modified Deckel clone? This same "argument" has been presented before. This machine is not, nor will it ever be, however heavily modified, a substitute for or even a reasonable facsimile of a Cincinnati #2 or a Monoset tool grinder. Not meant to do the same jobs and not nearly as versitile as either.

If your going to sharpen end mills you really need to run the wheel over the edge to be sharpened as in my picture. You will not get the proper surface or relief angle just by pushing the end mill into the edge or side of the wheel, you will only end up with a scalloped / concaved or hollow ground cutting edge and generate way too much heat to the cutters edge. As you can see you're running into all kinds of clearance issues. If you were to attempt to sharpen a smaller dia. end mill or a six fluted end mill the problem would be even worse. I'm not familiar with your machine but I have to agree with Lane, it looks like it's designed more for sharpening drill bits. Years ago there was a local sharpening shop in town that did saw blades and drill bits for what few factories were left at the time. His machine looked to be an exact copy of yours. I remember asking him if he could sharpen end mills on it and he said no. I also remember him telling me he paid close to $7000 for it.

100% right and no one said it was but those of us that don't have access to Cincinnati #2 or Monoset tool grinders have to make do with what we can get.

If you don't like the idea of a modified Deckel clone that's fine you don't have to use one if you don't want to.

You guys that work in machine shops with the fancy tools forget that most of us don't and we can't afford to mortgage the house to buy the equipment that you think is the right stuff (usually good old "merican iron).

Nuff said.
