Shop Work: Blade Sharpening

Shop Work: Blade Sharpening


In this video I demonstrate how I take a dirty, grimy, and dull blade and make it as good as new again with an easy cleaning process and a good sharpening. If you’ve got some worn out blades in your shop, implementing these practices can bring them back to life and save you lots of money in the long run. Check out the video, give it a like, and leave me a comment below!

UPDATE: Looks like they might be sold out. I found this machine which is very similar, and cheaper, but I’ve never dealt with the company selling it. Good luck!

    I bought this sharpener and the instructions left a lot to be desired. This video is awesome, I had it set up and working in a few inutes.

    I think you should do a video on sharpening damaged and burnt blades.. I can send you a large box of them so you can do a thorough job of it…. In fact I can even send you a check for the return postage so you’re not out anything! Should we start with 200? Trust me I have blades for every power and hand tool in almost anyone’s shop. Our cabinet shop, particularly the area where apprentices train, is an ENDLESS source of burnt, damaged and dulled blades! By the way…the blade sharpener can be made to advance and set each tooth automatically while your in the ….er…..ah….’echo chamber’ and automatically stop and make a loud buzzing noice (like your dryer) when it is done. I did this to mine for about $8.00 but then the apprentice used it… help a brother out?

    very good video. Clear, concise and great editing.

    "Cadmium, Chromium, Cobalt and Nickel are all metals used in tungsten carbide brazing and grinding.

    1. If you breathe in chunks of these materials they get into your lungs and can tear up the lung tissue. This is pure physical damage. In wet grinding it is chunks in the grinding fluid droplets. In dry grinding it is airborne chunks.

    2. Cadmium, Chromium, Cobalt and Nickel are all chemicals as well as metals. They can chemically react with your body to damage you. Everything is chemical.

    3. These metals also have different effects on different people. This is like an allergy. Everybody has different tolerances to different materials. "

    be VERY aware of the risk of grinding blades.
    you should be wearing an adequate respirator rated for heavy metals and be in the open when grinding.

    Are there specs available for setting your angles on the large variety of blades rather than doing it by eye?

  7. Don The Fat Bee Man on January 20, 2023 at 3:56 am

    I bought one but there is no one sell extra sharpening wheels

  8. Whitty's Workshop on January 20, 2023 at 3:57 am

    The angle on a crosscut tooth is known as "fleam" with hand tools, presume it’s the same for a circle blade……. Jus passin along some useless info in case anyone wondered 😆

  9. Borja Baragaño on January 20, 2023 at 3:58 am

    Thank you very much. I’ve ordered the machine here in Germany and now the blades are sharpened in no time. It is not just the money as you said, you have to go to he shop and then wait a week. Keep up the good videos.

  10. MAW74656 on January 20, 2023 at 3:59 am

    How do you know if a blade is worth sharpening? Like is there a minimum price blade that you would bother sharpening vs automatically getting a new one?

  11. Steven Michaud on January 20, 2023 at 3:59 am

    I Purchased this sharpening system , i can’t install my 5/8 arbor blades on it, is there something i’m missing ? blade will not slide over the arbor. can you inform me what to do, or how to contact them for correct arbor.
    thank you for your time.

  12. Dave Miller on January 20, 2023 at 4:00 am

    Great video as always. Thanks for the good information and keeping it fun too! Perfect timing because I was looking a sending my blades out for sharpening. All of our local saw shops in my area are gone. I like your solution much better. I managed to find one of these on alibaba and have a question. Did you have to modify the centering spacer for the 5/8" arbor. The smallest centering spacer mine came with is too big. I figured I can mount it to my lathe and get it to size, but thought I’d see if you had a similar issue.

  13. Minnesota Marine on January 20, 2023 at 4:02 am

    So one thing you should warn people about is that on a lot of saw blades the pitch alternates from tooth to tooth one left one right. If you just sharpen every tooth the same it’s going to throw the saw blade off and make curved cuts. You have to make sure that the angle of the carbide you’re sharpening is correct.

  14. William Domeracki on January 20, 2023 at 4:02 am

    Hi, question: what is the brand and model number of the sharpener? Great video.

  15. Lilo Ukulele on January 20, 2023 at 4:09 am

    After having the sharpening service mix up my blades with someone else’s blade and returned a 10" cheapie blade in lieu of my very expensive Freud melamine blade, I am sold on investing in a sharpener. NOTE: ALWAY SCRIBE YOUR NAME INTO YOUR BLADES BEFORE SENDING THEM OUT.

  16. Gabriel Paddock on January 20, 2023 at 4:10 am

    Your neighbor must be a really cool guy for letting you "borrow" his tools and unused materials

  17. Leeza Rhyne on January 20, 2023 at 4:11 am

    Where can you buy replacement 5" diamond grinding wheel with 1.26" arbor?

  18. Mandel Adams on January 20, 2023 at 4:12 am

    Are there common angle or a set of compound angles tooth profile for the type ( rip, crosscut ect.) and or tooth 🦷 count?

  19. vera badram polavaru on January 20, 2023 at 4:12 am

    I want this machine please

  20. Donald John Robinson on January 20, 2023 at 4:14 am

    Obviously you must have spent a lot of time cartoons, the intro part. 2nd part what I was really after.

  21. Jon Clearwater on January 20, 2023 at 4:15 am

    I love your videos. I wait with anticipation for new all the time. So easy to follow. Easy to understand. And the outtakes at the end give it a humble human Factor that makes it relatable. I appreciate you

  22. Rudy Rillera on January 20, 2023 at 4:17 am

    Very good video. Since this unit does not include a 5/8" bushing, were you able to use the included 15.8mm bushing or did you separately source a 5/8" bushing? The bushing you used for the 10" blade appeared to be a different color from the other bushings.

  23. Shawn on January 20, 2023 at 4:19 am

    I remember when LA totally awesome use to be sold at the dollar tree. Crazy to think its almost 10 bucks now

  24. Ursula Leach on January 20, 2023 at 4:21 am

    I have bought this machine because between a friend and myself there are plenty of blades to sharpen. But the directions on putting it together were lousy then I went to see if there was something on youtube to explain it step by step an there wasn’t . But watching your video and seeing how the machine was put together helped me to put mine together. Thanks for putting up this video, it was a great help and your explanation on how to sharpen them was great also.. Now to sharpen some blades ……………………………………………………………………………

  25. Skully Wood & Metal on January 20, 2023 at 4:21 am

    Great, now I have to buy another machine. Does your neighbor have an extra one?

  26. Brian on January 20, 2023 at 4:21 am

    Great video as always! Any idea why the blade is angled on one side? I guess I’m supposed to be using the flat side? The lack of instructions for this is horrible so I’m so glad you made a video!

  27. paul marchese on January 20, 2023 at 4:24 am

    Great video

  28. Mark Henry on January 20, 2023 at 4:24 am

    Well done…

  29. Grumbly Curmudgeon Woodworks on January 20, 2023 at 4:25 am

    @Fisher’s Shop: I’m absolutely not kidding about this: I discovered some years ago that *liquid laundry detergent (Gain, Tide, whatever. I use Persil) serves as a (bafflingly-) fantastic blade cleaner.* Same process as you described: submerge (only needs about 5 minutes of soak time), toothbrush, then simply rise with water and pat dry. Resin, burn mark, and even the gym locker room smell falls right off. Not a clue why it works. But I swear on my table saw’s life it does.

    The great part about this is everyone already has this sitting around the house (pretty much guaranteed), it’s totally non-toxic, and if you spill any on yourself? Your clothes get CLEANER.

    Important pro tip: while the solution absolutely IS reusable, same at the one you illustrated, it’s really, REALLY important you not pour it back into the starting bottle. My wife didn’t talk to me for a week.

    In my defense: who washes all of their white clothes at ONCE? Also, when you’re pouring a normally-sky-blue liquid and it comes out… we’ll call it "Space Gray", who shrugs, thinks, "huh. Weird." and _chucks it into the machine with all their white clothes anyway!?_

    …Additional pro tip: The above questions are _not_ the correct response when confronted by ones wife about this matter.)

  30. Gary Adams UK The Cockney Workshop on January 20, 2023 at 4:26 am

    My wife’s just bought me one
    It’s good
    spent the whole day sharpening
    Im hooked
    Cheers mate

  31. LilahLily87 on January 20, 2023 at 4:26 am

    Hello! I just stumbled onto your channel and have in the past week watched about 10 of your videos! My dad and I fiddle around with woodworking and have shared your videos with my him. I would like to make your game table and of course we will be making your jigs!

    I do have a question for you. Some of my dads measuring tools and squares are getting old (his t-square wiggles). With Father’s Day coming up my sister’s and I want to give him something nice! Do you have some suggestions? I really liked your triangle with the holes drilled in it to mark it.

    Thanks in advance!

  32. mike richards on January 20, 2023 at 4:28 am


  33. Alien Leader on January 20, 2023 at 4:30 am

    Sweet video as always. Thanks taking the time to explain this machine it will help in any furture decisions I make on whether is is worth getting one or not.

  34. Carl McLelland on January 20, 2023 at 4:30 am

    This should be considered a ‘must have’ tool for any woodworkers shop. I bought a Harbor Freight model ($55.00) and yea… it’s Harbor Freight quality. I took it apart, modified a few critical components to suit my needs – AND – it does a stellar job! As for blade cleaning, I use the wife’s liquid laundry detergent and put the blade in an old cookie sheet. Let it soak a while and use a toothbrush, and it comes out as clean as new.

  35. D S on January 20, 2023 at 4:32 am

    Enjoyed the humor.

  36. Stan Krieger on January 20, 2023 at 4:33 am

    Nicely done thank you

  37. Sean Signer on January 20, 2023 at 4:35 am

    It’s roughly 1/2HP. Please wear appropriate safety mask when grinding anything metal especially carbide!

  38. Joshua Cassella on January 20, 2023 at 4:36 am

    These machines really only do half the job, saw blades need to have their face and the tops of the teeth sharpened. Also be sure to have some kind of dust collection venting outside because the cobalt the carbide is bonded with is HIGHLY carcinogenic and the particles are so small that they stay suspended in the air for a long time and are too small for a basic respirators to filter out.

  39. Stop Abusing Statistics on January 20, 2023 at 4:38 am

    Did you ever test how much of a difference just cleaning the blade made without sharpening? I’ve heard of blades being revived just by cleaning off the pitch and other gunk.

  40. Richard Geertson on January 20, 2023 at 4:38 am

    Can this sharpener be set up to TOP the teeth?

  41. Andy Paxon on January 20, 2023 at 4:39 am

    What is the exact make or model of the machine please

  42. timb1024 on January 20, 2023 at 4:39 am

    Super Helpful – I see the options for a water-cooled sharpener…do you think water is necessary for the home shop sharpener guy doing just a few blades? Yours seemed to do just fine without! ??

  43. Mr MIG Man on January 20, 2023 at 4:40 am

    shame you cant do this with the metal tct blades..

  44. David Shassetz on January 20, 2023 at 4:40 am

    Do you know where I can get another sharpening disc? Mine broke apart after three uses.

  45. John Ronan on January 20, 2023 at 4:40 am

    Drew, great video as always.
    I bought one of these. Was just trying to sharpen a 12" blade with a 1" arbor for [what seems like] hours. Whenever I got it set right,I would turn it 180 degrees and it would not show the same depth of cut.
    I then realized that the arbor adapters seem to be METRIC! The resultant slop in using the [slightly-less-than] 1" meant that the blade wasn’t actually centered on the adapter. Elsewhere, I’ve read others with the same problem.

    Is it possible yours were metric as well? If so, how do you suppose you got such good results?

    Thanks for any input.

  46. John on January 20, 2023 at 4:41 am

    totally time to install a DIY shadow line lamp in your mitre saw too 😉 it makes it SO much easier for accurate cutting!

  47. Tyler on January 20, 2023 at 4:42 am

    you could have just moved next to a new neighbor. bam! fresh blades!

  48. Louis Whitney on January 20, 2023 at 4:42 am

    Boy did I need that…😂😂

  49. Mark Simoneau on January 20, 2023 at 4:44 am

    Ordered this sharpener after this video because it does seem economical. I struggled to figure out how to get the angle right, but beyond that, I also got a 5/8" insert that is just a little to big so none of my blades drop over it easily. Did yours work out of the box? And if you had a slight-too-big arbor, how would you reduce its size? A file? Sanded against a disc sander? I’m struggling to come up with a good idea that doesn’t ruin it.
