In the summer of 2013 I bought this old Servus cirkular saw blade sharpener. The company Servus still exists in Stockholm in Sweden though they claim to know nothing about theese old machines.
It was rusty and dirty and some moving parts were stuck so I took it apart completely and cheaned everything repaired some damage to the mechanism and shifted all bearings and lubricated everything. My intention was to fit it out with a diamond wheel and start sharpening my own blades.
Then I started researching on the internet. I was told that carbide blades have to be wet sharpened to avoiod fracturing the carbide and that theese old grinders aren't rigid enough to handle the needed grinding pressure for grinding carbide. I was also told that the diamond wheel gets destoyed if it touches the steel in the blade which it of cause will do when grinding the tops of the teeth. The guy who told me this claimed to run a sharpening service somewhere.
I abandoned the project but I could not make myself throw away my newly rebuilt grinder. It still lays under a heap of worn out welding gloves on a shelf in the tractor shed.
Now I have notised that the whole world seems to be full of consumer grade saw blade grinders like this one

They are all much less rigidly built than my old cast iron grinder. They are all made for dry grinding and they claim to be able to grind the tops of the teeth.
Did I get incorrect information and is my machine better than I believed?........or are the toolmongers selling junk as usual?
