Its been along time since I have posted anything due to an extended vacation and work related to my acerage, Its been several years that I have wanted to try sharpening my bandsaw blades so I put this project ahead of anything I have planned. I was inspired by a utube video by brandotown, and i suggest everyone that is interested watch his video. maybe someone could put a link in for me, not sure what to do.
I had an old grinder that someone gave me, no tool rest, but that was a blessing as the one I made works better. First blade I sharpened I used a wide stone, then I remembered a narrow stone that I had picked up on a clearance table, I like it alot better as you only need the corner. I put a slight slant on the stone and rounded the corner. I soon discovered I needed a light and remembered I had a lighted magnifying lamp in storage. The magnifier makes it easy and restful to see your work. otherwise your eyes go wonky trying to focus, with this setup I can pretty much sharpen a complete blade in one sitting. after hitting the tip of the tooth I just sharpen I had an idea of a guard and it works very well, esp on 6 tpi blades. I used a piece of hardwood to plug the surface of the grindstone so less chance of it wearing the guard away. I soon came up with the idea of pivoting with a little spring pressure, rubber band will do. The rest works well as it is a support for your fingers when holding the blade. I soon discovered that I should file the corner off for clearance for the set of the tooth that pointed down secured with one screw allows adjustment. Note also my cheap support and vibration damper for the light setup. Once I got on to it I could sharpen one tooth per second, It was so much fun I sharpened all 9 blades I had saved 124 in long. About 15 minutes so at $20 dollars a blade that is about $80 dollars an hour you are saving and they can be sharpened 4 or 5 times. brandotine found that a sharpened blade cut 5 times faster than a new one. he sharpens all blades before he uses them. If you do not try it you will never know how a sharp blade cuts. But watch the Utube video, as he explains the sharpening quite well. You cannot afford not to. Thanks for looking improvements and suggestions, and comments welcome. Questions answered. Brian
