    I would add a stop on the table so each time you slide the jig forward to sharpen a tooth you hit a positive stop. This would make it so you don’t have to worry about running the blade into the grinding disk and assuring that you grind the whole tooth each time. Love this jig. It’s a great solution.

      @@colinstace1758 Yeah, I've checked it out and it looked too much like their chainsaw blade sharpener, which I have. It uses a lot of the same ideas, and I would imagine, materials, for indexing and such. I was just too dissatisfied with the chainsaw blade sharpener to go that route again and for $55, I figured it was just a matter of time before someone smarter than me came up with an easier way to do it. Harbor Freight has some good deals sometimes they have some neat tools that a lot of the other big box stores just don't carry, so I shop there frequently, but for this purpose, I just wasn't interested. Thanks for letting me know about it though.

    Genius!
    I worked at a lumber yard one summer during college, and we had this radial arm saw. I used it occasionally, and never really thought much about it. Then one day, it got a new sawblade. That damn thing cut through wood so easily that the wood basically put up no resistance. It was literally like a hot knife through butter. On that day, I learned the importance of a sharp sawblade.

    Hello John. Just built this over the last week (had some problems fitting & adapting a Diamond wheel on the arbor), and sharpened a 24tooth ripping blade with it. It already had 1 tooth missing & one halfway chipped off, but after the sharpening it cut throug 60mm (2 & 3/8) ash wood like butter. I guess i won't send a sawblade out for sharpening anymore :)

  • @TheWrinkledCheese
    @TheWrinkledCheese Год назад

    Idea to make the "swing down stop" adjustable. Make the steel long enough for all the blades you plan on sharpening with the jig. On the bottom side make "steps" so it will swing down further for shorter blades. You will have to put different angles on the "steps" to get contact with the different sized blades. Because of the longer length, you'll probably want to have a block on either side of the "swing down stop" to help with any deflection on smaller blades. With thick enough steel you might not even need this.

  • @Etna.

  • @paulhamilton5634
    @paulhamilton5634 4 года назад

    Just some advice as I used to sharpen these as well a machine tool cutter for 3 years. The index should be on the backside (shoulder) for 2 reasons. First & most important it wil keep constant pressure of the tooth against the wheel. The way you are doing it you have to keep pressure with your hands. Possible kickback. Safety first!
    Second thing is when you get to that last tooth the index is going to be sitting against a freshly sharpened tooth making the last tooth to be sharpened sit further in. Yes, maybe only a. 003- .004 of an inch (machinist here). But it means that last tooth won't be engaging like the others & possibly causing premature wear or tooth breakage.

  • @sambo7326
    @sambo7326 4 года назад +8

    How do you deal with the alternating angle of the tooth faces? This does sharpen but just grinds them all flat. Should the grinding blade be set the right pitch and then just sharpen every other tooth then flip the blade over to get the remaining teeth, kind of like doing a chainsaw chain?

    • @JohnHeisz
      @JohnHeisz  4 года назад +4

      Most blades have flat teeth. The ones that have an angle (like the first one I sharpened in the video) can be ground flat as well.

    • @mattlibby4490
      @mattlibby4490 4 года назад +4

      For anyone who really wants to preserve those angles, it does seem like you could use the "set grinding disc's pitch" suggestion given above. You'd need to relocate the index to the other side of the disc for one of the setups. Also, some teeth on ATBR blades are still flat, so you'd have to do three setups per blade. Bit of a pain; I can see why John just wipes out those angles.

  • @John-d7p
    @John-d7p Месяц назад

    Having been a saw maker and service guy, this is a decent way to face the teeth. Just be careful to have the angle well matched, and don't remove more off any teeth than the others or else the generated path will be high/low, and the tops will need to be dressed as well. If a tooth is badly chipped out, better to face it like the others rather than grind it out. Go very easy so as not to heat up the carbide or the brazing solder.
    I would oil lthe table saw slot to give a very smooth, sliding action so the risk of a sudden stick/release is less. Should feel like a trombone.

    Along with wearing safety glasses and a respirator while sharpening your carbide blades, you should also be wearing your Blue Oyster Cult safety T shirt. 😁
    Thanks for the blade sharpening tip. I'm gonna try it.

    A question... When you get to that last several teeth, now, the tooth that is being caught by the metal swing down stop... has already been sharpened. And is therefore, 'shorter'. In other words, how do you keep from OVER-sharpening the last few teeth?

      I was wondering the same thing. The Harbor Freight sharpener is similar too.

    That's Wicked Heads up.
    I might add, to spring load the stop and index the blade clockwise .. so you dont have to constantly open and close the stop.

    Sharpening blades on the table saw is brilliant but why not allow the indexing block to pivot (spring load it) so you can turn the blade counterclockwise. As you do so, the blade will push the pivoting index block out of the way until you turn it far enough for the tooth to clear - then it snaps back into place and you’re ready to grind the next tooth. Another good idea would be an adjustable stop hanging off the back of the jig that would stop at the front edge of the table so you never have to worry about pushing the jig too far forward.

    Yup, carbide dust is pretty carcinogenic. We have a specific room at the machine shop where I work for grinding carbide cutters and endmills. It's set up with negative pressure and some pretty beefy high flow air filters.
    That's for an industrial scale operation though. If you're just touching up a saw blade at home, a half face respirator and a fan blowing dust out the door is plenty.

    Whoa team. Every other tooth has a different angle on the face,,, one shouldn't EVER put a flat face on these teeth. I gave a thumbs up, and thank you for the video,,,,,, but this is why I NEVER let anyone sharpen ANYTHING for me.

    Wouldn't the index be better on the side that has already been sharpened ? I would think that would keep it more uniform or am I missing something ?
