no I'm saying that when they made that grinder on ebay, they took a cylinder of aluminum and bored out the inside, they then stuck/welded the tines on. This is no good.
Now the space case picture you posted, you can clearly tell that is a quality grinder because you can see a little halo around every tine where the cnc tool carved it out, this means that the tines started out life on the same piece of metal as the thing you will be turning with your hand, this is good.
