A jig, made from a battery powered circular saw, for sharpening circular saw blades.

      The teeth on the blade have an alternating left and right angle, so your sharpener needs to be able to allow for that left and right tilt angle.

      So where did you get the cool knobs? After watching this I almost think that you sharpener is better than the Harbor Freight one!

      Worst jig I've ever seen. You didn't have the mindset for design. At least not a very good one. Don't waste your time watching this dumpster diver try to make something from nothing.

      You would be wise to look at the Foley Band saw sharpeners--I use model 310 it does the job fast a perfect every time. This is a commercial tool-it is old and worth about $300.00

      Nice jig and right you are on carbide dust being bad for lungs. In fact, no dust is good for them. Although I have gooddust collection, I still wear a cloth face mask from SA covered with a 3M fine particle mask anytime a saw, router, grinder or any other dust maker goes on. Usually have a fan to pull it outside as well. I have to wear the 2 masks due to my beard keeping just the 3M mask from fitting well. Again, nice jig. Been using a Trend Diamond Credit card, 600 or 1000 grit on all of my carbide tips. Fell in love with the Trend stuff for my carbide lathe tips.

      Was going to crack a joke about too much time on your hands, when I remembered that I spent all morning watching you and John Heisz make jigs and actually accomplish things. :)

      it looks like the carbide teeth are slightly misaligned and hences getting score marks .. you may side grind too so they are all exactly at same side tolerance.You could caliper measure each carbide thickness and then calculate the width of the cut and conclude how much variation there is in the blade

      Mathias - Check out this video and try his method. It certainly seems simple enough. Though your method would be more fun and a challenge to make.

      *The saw works beautifully.>>>**ur2.pl/792** I highly recommend for anyone looking for an awesome saw, and who already owns other Dewalt battery operated tools. I was using 5Ah batteries with the saw, as I don't think the smaller batteries can provide enough juice.*

      Great jig ...blade sounds sharp...aren't the teeth pitched in & out on circular saw blades? Maybe you need to bend the teeth in & out for the cut you want?? It sure sounded sharp and i thought you cut very fast.

      nice sharpener! ive seen people do it on the table saw itself with a diamond blade and a jig that slides in the miter slot. this way you can also tilt the blade to add fleam, this would get you a cleaner cut.
