Bader grinding a full tang surface totally flat

[neil1967]

Okay, I'm having a problem. I am trying to use the flat platten on a Bader grinder to flatten the sides of full tang so I can attach the handle slabs but I can't seem to get it to go totally flat. There is a little bow in it where it is higher in the center (holding the tang vertical against the platten). I have checked the platten itself and it is flat, and I'm using spanking new belts, but I keep having this problem. Has anyone run across this? And if so, is there a solution?

Thanks!

Neil
