This was harder for me than I thought it would be. I grabbed two abused chisels from a thrift store. I don't have the expensive stones in some of the videos but a shop I'm currently working at had a bench grinder so I watched all the chisel sharpening videos, I went with the one featuring a bench grinder. I finished the sharpening on board mounted 600 grit emery paper.
The one in the video seems much nicer with respect to the stages you can use to balance and guide to the grinding surfaces. I sharpened a thin chisel with a blade thinner than the grinding wheel and one that was thicker. While I didn't fine either easy, I learned a lot for next time. The thinner blade was easier on the wheel than trying to go side-to-side with the thicker chisel. I had a heck of a time trying to grind a straight cutting edge given all the motion. Even with much care it was difficult for me. Even though I used water as a coolant, I still ended up overheating a bit. Anyway, while mine aren't nearly as pretty as those in the videos, they were brought back to a decent blade and worked well on some scrap stock. I hope to use them on some wood windows that have some rot in them soon. Anyway, good exercise for me. Hopefully next time I can make them a bit more pretty.
