Harbor Freight Circular saw blade sharpener review ( Chicago Electric)

[@dpaulsen1]

Forget about cutting anything other than paneling or thin plywood ... even 3/4" ply bogs it down a lot even when cutting a very VERY slow path. Probably Works great kzbin.infoUgkxjpBI8OOeUXib_iT7UomCrQ-uauwZJ62c on drywall but who needs the mess of dust flying everywhere when a knife cut will do. Oh, and the red tab on the guard blocks your view of the cutting line once the blade is fully engaged in a cut.

[@bradleyleben7785]

I bought one about four years ago just to see how it worked like you did. I sharpened the blade on my Ryobi chopsaw just like the one you have. And low and behold it was cutting near perfect. Was it worth the $49.95.? Heck yeah. I sharpened about 18 blades of all different kinds and then try them out. They worked good. Your review was just like I felt and experienced. Excellent review Brad

[@Bushradical]

Thanks Bradley

[@thorlo1278]

Since I ran a sharpening business back in the mid 70's, I already knew how to sharpen saw blades. As several other guys have stated, blades are either angled left and right to be sharpened that way unless it a flat ground blade. Also, as others have mentioned, that diamond sharpening blade is okay to do the initial grind on very badly messed up blades, you then need to go to a finer grind wheel to help with the sharpening, but then you need to go to at least a 500 grit grind wheel to hone the saw blade. The original grit on the grind wheel it comes with is a 120 grit blade which is way too coarse for final sharpening. You need to go to at least a 280 or 320 grit before using a 500 grit.

[@cferguson6688]

hey, don't be so picky, this isn't for the professional, its for us people out here in the woods that don't want to run 30 miles into town to pay someone to sharpen a blade> Gezz, its a damn $50 sharpener, beats the hell out of using a grinderl in which I had to do ..

[@MrPatdeeee]

@@cferguson6688 One should ALWAYS try to do the job RIGHT; regardless of their education or lack thereof; not to mention that "if you can't do it RIGHT don't do it at all". Because IF you do not follow this golden rule, your life will be as this BrushRadical lives. IE: Having tools that he has to "work around", because they have not done what they should have. Oh indeed yes. Believe it or not.

[@cferguson6688]

@@MrPatdeeee I agree somewhat, but some of these people are comparing this little machine to thousand dollar machines and they are stationary to get it "precise on". Of course it isn't going to be "right on". Otheres and myself agree, if the blade gets sharp and does the job, then the job was done right not matter if its not "right on". THAT is what I was getting at. The way your sounding is that "no one " should buy this and spend the money and time to go to town to a blade sharpened. Oh yea, I use to go and have the blades "professionally" sharpened until the sharpening place closed down, now I would have to drive 50 miles one way to do this, cheaper to just buy a new blade then. The little machines save money and time and gets the job done. That is all that matters to me.

[@bobybull]

thorlo6 I’m glad you’ve explained what a professional think of this. I have a clearer view now. Thx

[@texasbrowncoat]

Question sir... I was told that tungsten carbide teeth are square to the blade but regular blades are mitered. The carbide teeth are thicker than the blade so the cut provides the clearance needed but a 'regular' steel blade has the mitered teeth to achieve the clearance needed, cutting the left side, then the right side, alternately. Is this true?

[@derrickwood1453]

PRO TIP - The blades have right and left hand teeth. Each side must be sharpened separately with a 20-25 degree angle (similar to a chainsaw teeth). There is a setting on the back of tthe machine in order to tilt the motor to accomadate this needed angle. This one adjustment will make the blades cut smoother and cleaner!

[@muimasmacho]

Derrick Wood, Absolutely. That's why every OTHER tooth is making heavy contact with the diamond wheel. Just cut the life out of that blade in half, at least.

[@boydmerriman]

I was suspicious about this. Not all blades are the same angle. Thanks for letting us know about the adjustment on the back. I hope he sees this.

[@zaugitude]

Indeed! The lack of alternating set angles was the first thing I wondered about as I watched him set it up. Thanks for the tip!

[@georgesweap7]

The kerf of the saw blade is very important because the cutting edge angle of the blade needs a relief angle provided by every other blade so as to reduce the friction of the blade cut and provide longer blade life! Obvious, both the instructions and the presenter, do not know the geometry of a saw blade!

[@tornadokat]

The "right and left hand" is called fleam. Fleam is usually slight, or neutral, in a rip blade and more pronounced in a cross cut blade. A chop saw should have a cross cut geometry so my first thought was the same... running each tooth through that sharpener without changing the angle will ruin the original tooth geometry.

[@richardvsassoon5144]

And , despite having to watch the grinding action a bit too often, the different angles helped answer some questions. Liked the different size diameter demonstration as well...but the question that brought me here is - how to sharpen hole saws?

[@dang5203]

Bushradical Good video and review friend! I’m seeing this tool online for $55-$70 new, less for used. I’m a woodworker, not in concrete, short of small jobs. Wondering if a steel blade would be best for your dirty lumber for concrete work. Carbide doesn’t like sand and minerals. I’d think you’d be loosing teeth with a carbide blade on that type of lumber. Also, wondering if adjusting blade stop on steel in gullet, below the carbide would give more consistent tooth grind. If carbide tooth is chipped, you’d end up with different grind depths I’d think. Thoughts? Also, for dedicated wood working, I’d spend the extra bucks on a bit better blade. If wood being cut is clean, they’ll stay sharp a good while. The red Freuds are a great mid range economical choice. For high end, Forrest is hard to beat. As to the question of hole saw sharpening - I haven’t tried that yet. I’d think Dremel or hand file, and a steady hand, might be the only options there.

[@joescheckler9953]

I, also, found the presentation to be logical, well presented and very informative - as opposed to other, not-so-well-done, ones from other sources. Based on the clearly and logically done content I chose to buy a sharpener, too. I have plenty of blades to work on and I'm sure the neighbors will have even more, too. The clear camera work was exceptionally well done as well.

[@joseherrera7654]

Well done

[@24getful1]

I bought it today, decided to give it a shot and after watching your video as well as a few other I set it up. I sharpened 4 blades and more to go. It does a great job sharpening the blades. I have trouble getting the horizontal blade arm to stop moving... If I tighten it any more I would probably snap the knob off. As for the bolt that tightens the Guide Arm it's neither Metric or standard and using the adjustable will eventually strip out. Same goes for the Bolt that secures stop for the blade alignment. All and all for the price you can't go wrong. Great video, thank you.

[@Bushradical]

Thanks

Try putting a lock washer, had the same problem. Adding the lock washer dit the trick.

[@rabbycacker]

I agree 100% with what you were saying about a cup of coffee and taking the time at the end of the day. Been fixing stuff my whole life, partly due to lack of money but a lot of times back in the day here in rural Alaska you had to fix it or do without. That was way back before the throwaway economy and all of the big box stores. The way I see it is if your option is buying a new one or repairing the one you have then, the time spent divided into the replacement cost becomes your value per hour of your time. Of course sometimes it works out where your time has no value in which case you chalk it up to honing or learning new skills or just practice. Thanks for the review of the sharpener. Think I'll be adding that one to the tool pile.

[@Bushradical]

Thanks Rabbycracker. Where in Alaska are you. I have a place north of Fairbanks

[@jvaran5618]

I do a LOT of hobby woodworking, using all sorts of soft and hard woods. and over the last 3 or 4 years that i've owned this machine i cant even estimate how much money it has saved me... YES it takes some fiddling to get set up right but once done, i've sharpened half dozen blades in prob way less than an hour start to finish. have not bought a new blade in in at least 5 years. at some point the carbide will wear down into the socket in the gullet, and by then i'll feel justified in buying new, but for the forseeable future, i'll just keep sharpenin' away. great value for $$

[@Bushradical]

Right on!!

[@justplainducky]

I have one and the motor tilts, if I find my blade has alternate angles i can tilt the motor, sharpen every other one then go back to the beginning, tilt the motor the other way and sharpen the others, trust me it's a great machine

[@davidjones8680]

Yet another great informative and instructional video to watch and enjoy. A problem i get on my saw blade is not always that they go dull, but the teeth get a build up of resin on the side and back of the teeth. This I find leads to burn marks appearing on the cut surfaces, especially so on hard woods. Every so often i just take the time to clean the blade and it makes a big difference. David in the U.K.

[@youthised58]

Yup, every other tooth is different. That's why the grinding blade hogged in on every other tooth. Should have checheed the pitch and skipped one all the way around. Then reset the grinder for the new angle an cut every other one all the way around

[@leiphasw]

Bought one of these a couple years ago and never got it set up. It has been sitting in my office with a chop saw blade on it since the day I took it out of the box. Finally decided to watch someone use it! Now I think I’ll get my stack of old blades and get them working again! Thanks for the good video!

[@rakentrail]

I've owned one for 6+ years. I dress my finish blades as soon as they start to show fuzz or chipping. For an inexpensive machine it's held up well and it's saved me a lot of money in not replacing blades! Joinery requires extremely sharp tools!

[@kennethpierce7304]

I haven’t read all the comments but first thanks for shelling out your own money to give us a review on this product. Just a bit of advice if you don’t mind. When setting up to sharpen your blades, set the blade so the grinding wheel will take a tiny, tiny bit more off the heel of the tooth than the very front edge. You will get a much cleaner cut.

[@Bushradical]

Thanks!

[@douglasgault2578]

What other reviewers made it complicated you've made it easier,. Great review and demo. Thanks for posting it. I have one of these tools, and yes, mine came up with some issues that neede to be addressed. Like the knob that tightens the blade kept getting loose while sharpening, and what I did to fix it was to get a longer stud and add a thrust bearing of 11 millimeters. (eBay item that cost me less than a dollar). Another problem I dealt with was the base that slides towards the blade, that is mounted on two bars, and fastened to the bars with a small plate. I replaced the small plate for a full-size brass plate to make it more stable. After these little work, I got rid of all problems an now it works like a charm. I hope this comment will help someone.

[@AndrewBrowner]

i believe you only need to touch each tooth once, probably a little sooner than when it starts throwing smoke though, and notice next time youre aat the store the 100$ blades have alot more carbide on them than the 40$ ones, so you can sharpen them 8-12 times rather than 2-4 times and theyll last alot longer and cut cleaner between sharpenings.. might have a dedicated blade for the concrete uincrusted nail embedded wood though

Hi Jim. Your best indexing off the gullet as the last tooth to grind will be indexed off the first tooth which has already been ground. Also if the blade has a tooth missing you've got nothing to index off. Tony

The areas you pointed out where you think it’s been attempted to be sharpened are most likely where metal has been removed to balance the blade.

[@tyrsafray4640]

As ProTip pointed out, there are left hand and right hand kerfs on any blade. Some high end finish cut carbide blades have a center chisel tooth every third tooth. When sharpening high and low end blades you should expect to re-set the machine for each tooth condition ie. every other tooth is facing right or left with a corresponding angle so on a low end blade you need to do half the teeth in one direction and then flip. On some high end finish blades you will need a third process for the chisel tooth configuration

[@adude7050]

[@craigsudman4556]

I've been a carpenter for over 11 years and I use to have my blades professionally sharpened. They were exceptionally sharp but it use to cost me $70.00 to have them all sharpened. Since I bought the Harbour Freight sharpener I've been sharpening my own blades and I have to say for a low cost machine it does a fine job. I've even put different diamond blades on the sharpener to do different types of sharpening jobs. For the amount of money it cost you really can't go wrong. Thumbs up.

[@Bushradical]

Thanks Craig

[@WASTUDIOS100]

The contrast in tooth grind is most probably due to the crosscut blade as opposed to a rip blade ( which is what this sharpener is designed for. It’s for flat faced ripping blades. It doesn’t address the alternating bevel blades of a more complex blade designed for combination cuts or specific cross cuts. Nonetheless a sharp blade is better than a dull blade even if it’s grind is less efficient

[@moonolyth]

Interesting. I was able to get the angles out of it for that, albeit not a very precise tool.

[@chrisgriffith1573]

I applaud you for your great video showing precisely the steps and mechanics of this machine. I can see the issues which I know will be problematic on this device due to its design, and the imperfect condition of older blades. The "stop" for the blade tooth is never accurate from tooth to tooth, some will be damaged or more or less worn, and the next tooth will not contact the diamond blade accurately or at all, so care must be taken to adjust the teeth at each step. I would have gone with a two step process for advancing teeth. First advance the machine to a static guard set to the placement of the grinding wheel (part of the grinding wheel guard itself), lock the blade, remove the static guard by pulling the lever and grind the tooth, the second arm is not needed at all.

[@clconstruction3072]

Very nice video and thanks for explaining how the sharpener works. Don't really feel like arguing with anyone but I took a look at an old blade of mine and the faces were all set 90 degrees to the body of the blade, so the procedure you outlined will work perfectly. There may indeed be blades where the grind of the face is at angles with the body of the blade and so you would have to take that into account if you have such a blade. In the blade I have, the tops of the teeth do indeed alternate angles, but that is a function of how the top of the teeth are ground. I've read that this sharpener will do that but my opinion is that if you have a sharp edge on that tooth, it really wouldn't make much of a difference. Mind you, I don't need super fine cuts to do the work I do.

[@jeepinon35s]

You can set the angle on the sharpener.

[@jasonbabila6006]

Good info, I have 10” and 12” blades that varies between $30 to $55 and it is expensive and does add up after replacing the blades over time, having the ability to sharpen our own blades will help cut costs down.

[@Bushradical]

right on!

[@CraftsmanontheLake]

I did a review on this tool here years ago. It works pretty good but I only delegate it to older blades. My good ones I send out to be professionally sharpened. Another note: If you look at the directions I think you left out a very important part. Notice underneath the sharpening wheel there is a place to put an allen wrench in and tilt the whole motor/sharpener unit up or down. One tooth needs to be sharpened at one (+) angle and the other at another (-) angle. This is how a saw blade works. The same reason teeth are offset on a handsaw. Your blades would cut much better if you did that. So you sharpen every other tooth in one angle then change it and do the other teeth the negative angle.

[@Bushradical]

Thanks Daniel....but I don't understand exactly what you mean. Ive been hand sharpening saws for years. I know all about set. These teeth have alternating tips (left /right) when you look at the blade face one.....but the faces of the carbides themselves seem to be totally flat like a rip saw.

[@CraftsmanontheLake]

Yes, I should have said tooth angle. The term 'set' is only used for handsaws. Most circular saw blade types have alternating angles. If you don't tilt the grinding wheel, each angle will be square. Here is a graphic I found that shows different blades and angles. And, look beneath the grinding wheel. There is a -10 degree and +10 degree adjustment for just this purpose. The directions that came with the device go into length about making this adjustment. s26462.pcdn.co/wp-content/uploads/Sawblades_5F00_anatomy1.jpg Also, a link to the old 2012 video I did on this.

John Boehm opposite angles yes on some blades similar to how a chainsaw is sharpened.

[@bobwitt305]

@@johnboehm2593 on some blades it's a different angle on every third tooth.

[@MyUncleT]

Not to be negative, but the teeth on almost any kind of saw blades are pitched. That goes for hand saws, band saws , circular saws, scroll saws jig saws and even hack saws. Every next tooth is either raked (off-set or pushed out in opposite direction and or ground at an angle as on some circular saw blades of about 6 to 10 degrees). And it also helps to remove the waste material. So look at a blade or even a chain saw and you'll see the pitched teeth. So if you can pitch the cutting wheel and sharpen every other tooth in one direction, then the opposite on the other side, it will be like a new blade.

[@Bushradical]

Thanks. I'm familiar with tooth geometry as I've owned a band saw-mill and have sharpened and set the teeth on dozens of handsaws, but the blades I sharpened in this video had zero angle to their faces. They were all pretty cheap blades.

[@SherwoodBotsford]

Nice review. Tip: Mark the tooth you start with a felt tip marker. Tip: When you find a tooth where it barely touches put a dot on that tooth. When one misses, put 2 dots. After you make the first round, move the stop up by a bit (This tool needs a screw adjustment for that.) and regrind all the teeth. Repeat this until it has the same contact on all teeth. In theory you need to do the top face of the teeth too. This one doesn't seem to be able to do that.

[@spencerboaz2385]

As many of the commenters here , I have one . But I don't use mine the same way , I don't use the blade stop and I don't feed the diamond wheel across the tooth . I simply pull the diamond wheel into the gullet of the saw blade then spin the saw blade to very lightly kiss the face of the tooth for a second or two . That way the tooth touches a completely flat surface on the diamond wheel . I have tried both ways and get much sharper blades my way . When dragging across the tooth the diamond wheel pushes off and you don't get a perfect flat cut and it seems to have a smother finished surface on the face of the tooth , adding to longer sharpness from the blade and less heat on long rips . Great video , try my way and see if you agree .

They are just nay-sayers, I've had one for a couple years, does have to be set, but once done, works great, can sharpen a bunch of blades in no time.

[@myopinion6328]

I think just some blade cleaning in general would help...looks like years of pitch built up on the blade...that also causes friction...just sayin

[@hugoquinonez00]

I bought this little machine and it works great! I just sharpened 5 blades less than an hour

[@chaoscentral5547]

teeth on blades alternate to keep balance and prevents drifting, would enplane your every other gouging.

[@greghackney8437]

Yep, I wonder if the instructions covered that.

[@bzu4113]

Great video! That explain why my saw produced lots of smoke and how to fix it.

[@regalbowman3143]

Looks like your purchase of the saw blade sharpener was better than my drill bit sharpener who's tolerances were designed by the hand grenades and horse shoe engineers specifications

[@Bushradical]

Did you ever have any luck with the bit sharpener? Ive never used one. But I do sharpen bits by hand....it works but you have to pay attention.

[@regalbowman3143]

The drill bit sharpener never did work correctly, the drill bit holder was poorly designed resulting in erugular sharpening angles,,,JUNK,,,

[@rwhite9994]

I have owned one of these for 7yrs now, and they do decent. They will not get a blade as sharp as factory or if you sent them off to a professional to sharp, like say Frued. Got to get the angle just right when doing 7 1/4 or 10" blades that are angled. Please expect to spend at least 30-45min per blade to do it right, and use both grits. The cost per blade per time may not be worth it for cheap 7 1/4" blades, but for 60+ tooth 10" blades on up that cost 60-120$ .... very worth it.

[@cherylt8590]

Thumbs up for sure,ty for sharing your review on it👍😊...

[@Bushradical]

Thanks Cheryl!

[@bret_Lambky]

I just used my buddies sharpener! It requires a few tweaks. It deserves a 👍🏼 it has potential to be a great asset to anyone’s shop!

[@Bushradical]

Thats a good assessment. Not perfect, but usable and has potential!

[@bret_Lambky]

Bushradical, I added a washers in a couple of the areas to allow easier adjustment. Also to eliminate any gouging the metal parts into the cast Aluminum.

[@Bushradical]

right on

[@darksmirth1178]

new blade for every job, job pays for the blade. my time is worth more than the savings... but thanks for the review, my curiosity is satisfied

[@woodsmatful]

Agreed

[@jak_k]

Can I have your old blades? :-)

[@jeffnotti9932]

sharpeners ROCK!. i have a drill doctor too and that is awesome for drills. my dad could free hand sharpen a drill on a pedestal grinder and sharpen a saw and a saw blade with a file. But having good sharpeners for your tools will make them last for generations. I have been agonizing over bench sharpening knives, it took me a little time to realize i was fighting knife geometry. (story for another time) my point is a Tormek for sharpening blades for of planes, chisels, jointers, and thickness planers is worth it's weight in gold... sharpen on man! J

[@Bushradical]

I will have to look up Tormek.

[@PavlovsBob]

Thanks Dave! I'll be getting one for sure 👍

[@robertjames-life4768]

Take an old frying pan, fill it with an inch of Simple Green and soak your blades for a 1/2 hour or so, then scrub with a brush. You’re blades are filthy. 50/50 liquid clothes detergent and water works too. Be sure to remove all water with WD40. Thanks for sharing.

[@gvi341984]

Blade face needs to be polished since friction increases resistance.

[@tjellis1479]

YEP- you're correct sir, wood resin/glue is more than half the wear and tear....most people ignore it or dont pay any mind to it.

[@patzeuner3362]

Soak the blades in a pan with Simple Green for a couple hours to overnight, use old toothbrush for scrubbing. WD40 for rust. Works great and inexpensive.

[@williamfifrick201]

Fantastic review. You did a great job of showing what you were doing and why. I will buy one after seeing your review. Thanks for sharing and well done.

[@Bushradical]

Thanks

[@raul7293]

Well, you definitely sold it to me!! I like it. I like tools Thank you.

[@dennismadigan2023]

Thanks man! I bought one a few years ago but didn't get around to setting it up to use it. I have at least 10 dull blades and like you the blade on my combo chop saw is dull as crap. You got me motivated to get r done. Thanks

[@Bushradical]

Good luck!

[@wolflahti412]

Cleaning your saw blades will go a long way toward improving the cut.

[@tyler4q692]

Just sledgehammer the wood or sheet metal instead of using saw

[@williambell9068]

Thanks for the review video. I have this, I bought almost a year ago and have yet to set it up. Need to get it going as like you I bought it because it is cheaper than a couple of my chop saw blades. I have a HF chain saw sharpener I have used for several years and it is way more accurate than my attempts at hand filing. Found your site after watching your wife and her stihl saw video then some of her fire ones. thank you both!

[@Bushradical]

Thanks William. Ive never tried anything for sharpening chainsaws except a file.....which model did you buy?

[@williambell9068]

Mine is a few years older so the chain vise part is different but this is the model now www.harborfreight.com/electric-chain-saw-sharpener-61613.html have a stihl 034 super, old saw but still a great one and a newer 170. sharpens both style chains with out much adjustment between them. Only $28 on the web today. Thanks again

[@Bushradical]

Thats awesome...I have a Stihl 034!

[@Bushradical]

I used to run a 036 but I sold it on the Yukon river 5 years ago. I replaced it with an 034 a guy had for sale. It was like new. Looked like the guy never used it. It had like a 24" bar on it. I think I put a 16" on it as Its a lot of load to run that big bar through some of the big hardwood I have on the property.

[@williambell9068]

I bought mine lightly used about 20 years ago. Like I said it is a model 034 super which I forget made it dif. I have 16 on it and a 20 if i need it. I live in central new york state cutting my firewood every yr and it only has had a couple plug changes in that time. It gets heavy so I got the 170 about 10yrs ago for the smaller and limbing.

[@frankartieta7483]

I like this video ! If nothing else this is a honest review ! What is more is the fact that you really can get a no cutting blade to cut again ! A highbrow cabinet-maker is liable to tell you This can not be done ! I am not a cabinet-maker ! If it cuts it cuts :) Best TU U and TNX

[@FrugalFlyRodder]

I was at Harbor Freight today and saw this sharpener. I wanted to see a demo/review before buying. My questions are answered... great video thanks. Like and subscribed.

[@fiskfarm]

Anyone else freeze watching this? Otherwise great vid. I'm sold.

[@Bushradical]

LOL, thanks

[@MikeEgypte]

Yep

[@stevezabriskie9839]

Great video! Thanks

[@philiphorton1661]

nice video, I was watching a video a while back that said if you soak a blade in a degreaser or something similar to remove all the timber gum off the blade this will also help with the cut as it doesn't bind as much on the blade when cutting, and as said previously, left and right-hand angles, mark the teeth that you intend on doing on one angle then skip the ones without marks

[@johnp2724]

Get rid of the tooth holder and use your hands to push the saw blade against the diamond wheel. Also mark a few teeth with a marker to confirm the angle is correct. you can do this by turning the diamond wheel against the saw blade. When the marker is scrapped off on the tooth you will see your angle adjust angle if needed. Be careful of saw blades that have a angle on every other tooth.

[@Sillyturner]

Good advice on getting rid of the tool hold and pushing the saw blade against the wheel. I’ve had one of these sharpeners for several year and sharpened countless blades. The tooth holder is just a big nuance and can even lead to a lot of frustration.

[@Bushradical]

good info. Thanks

[@JG-vh6mn]

@@Bushradical Not good info. The force of the wheel is going to push backwards and you end up with a negative angle face. If your just touching the face to a wheel you may keep it straight only if the face of the wheel matches the size of the tooth. Still, you won't be taking an equal amount off each tooth. Not to mention losing a fingertip because you have no control over the blade anymore.

[@patzeuner3362]

Check out a new saw blade with a square, what you perceive as different angles on the tips/face is actually an optical illusion.

[@JG-vh6mn]

@@patzeuner3362 This is about resharpened blades not new ones. New ones are sharpened with an indexing plate not a spring loaded finger.

[@phil3332]

Hi I live in the UK - England and l found this intresting to watch as l have many blades that need sharping. Thanks

[@boydmerriman]

Great review, I didn't know HB had one! I keep buying cheap blades for my skill saw (not Skill brand) and before I know it, its dull! I have also seen blades that threw me off my line because the two sides were sharpened unevenly. So make sure you are considering the two sides of the blade and its angle or it can drag you off line.

[@carrollthim8460]

soune good to me I sharper some to

[@YourLocalIceMan]

Many harbor freight tools have pleasantly surprised me over the years.

[@toonybrain]

Ice Rink Diaries Agree. For the money, there’s nothing out there that can beat my heavy-duty plunge router. And I have an older Chicago Electric planer that’s a workhorse.

[@woodsie5474]

You need to start by cleaning the blade first with solvent to get the gums and varnishes off it. There is a lot of difference between a gummed up blade and a clean one.

[@libertybarker7401]

woodsie5474 * he dose not need to do anything. but you are a know it all wayching you tube for why? since u kno it all?

[@aguilayserpiente]

A file and clamp still work to sharpen a saw blade. A large table saw with a good bearing would make matters easier. Those small 1 hp table saws are good for fine pieces of wood < inch. Thank you for the educational video.

[@BoJangles3105]

Good vid and verdict. Well done!

[@ClayBlasdel44]

great review. Good demo, no BS, all useful info. Thanks man.

[@pctatc66]

you hit the nail on the head.. if you're a contractor with a bunch of beat to hell blades this machine is for you. If you are a woodworker with expensive multiple/alternate grind blades, this machine is NOT for you as it will destroy your $100 woodworker II blade!

[@Bushradical]

yup

[@vertigo72480_official]

That thing is not getting anywhere near my Ridge Carbide blades.

[@fontking1a]

You can find saw blade sharpeners that cost over $500.00 and even way higher than that. For $45.00 this baby is a steal. How can you not buy one? I just ordered mine yesterday and have at least 25 blades waiting to be sharpened. Some of my blades are in the $50.00 and up range. Once my unit arrives, I will examine it and remove the "play" from the entire mechanism. I'm sure a few washers here and there will increase the performance. You can always find small things that need a slight improvement. Also, the unit can probably sharpen knife blades with a couple of add-ons. This was a very good video. Great job!!

[@Bushradical]

Thanks

[@MastercraftKARIGAR]

I can hear blade ringing sound after each cut you made which is a sign of unbalanced blade . Who else noticed it ?

[@Bushradical]

I didn't.....I don't know anything about sharpening blades...just a first impression video..

[@konaok1]

Balance, I don't need no STINKIN BALANCE! You're worried about balance with a junk blade and a $10 saw, cutting scrap wood.

Thanks WLBC

[@stephenrichie4646]

Those blades sure could use a cleaning. That’ll make em cut easier, too.

[@scotthager8691]

Nice point, pitch(sap) on the sides of blades instantly gets hot and sticky. Pitch remover used on planer. Blades too

[@shawnr771]

After seeing this review. I am going to have to buy one of these. Over the years I have cleaned up numerous garages and old barns that contained hundreds of circular saw blades. Buying one of these sharpeners would be the ticket to having a low cost supply of decent quality blades. Using self sharpened blades on less than quality cuts would be great saving my newer blades for finish cuts.

[@Bushradical]

I totally agree.
