Does anyone have experience on the use of a bench top disc sander such as

or the

for grinding steel edges/blades. I actually was not looking at this unit but it was the one I found easy reference on line to give a link for what I was talking about.
I thought about the HF disc sander but discarded that idea.
I have been trying to come up with a good solution for sharpening my chipper's chip blades and bed knife without overheating or hollow grinding the blade while keeping a rather accurate angle on the edge. The blades are 1/2" steel (yes it is a big chipper) and would like to have a stable platform to do the grind with minimal challenges. The chipper has 9 chip blades (3 sets of 3) and one large bed knife on it and the experts who claim they know what they are doing keep screwing them up and damaging the blades which are very expensive to replace. Do the abrasive discs work well and last or are they too much trouble. This above unit and one other has a variable spin speed which should help keep the temp down which can be deadly to the steel edge.
