Thanks! Easiest diagnoses I've ever found. I had the same thing happen as you, the blade spun and then I had this horrible wobble. I broke out the manual and that was zero help. Found your video and was able to just measure the bushing with my micrometer and found it off several thousandths. I ordered new a new bushing and boom! Thanks again for the great video.

I’ll start by thanking you!! I followed your video step by step to determine that the inner washer was in fact the reason for the wobble in my blade. I have a Dewalt service center near me and when I called, they tried their best to have me take my saw to them and have it serviced. However, I purchased the inner washer and the blade guide. Total cost $8.31. My saw runs like new. Thank you for your step by step diagnosis and saving me allot of money.

Very systematic. I'm glad you had a new bushing so we weren't left wondering. And then the additional information of what would be your next tests. The importance of proper tool maintenance cannot be over emphasized. Thanks for the detailed diagnosis and documentation.

i have seen your video before and lost it. you have the only video that explains this in detail. thanks a lot. Time to check out my bushing. thanks again

Forget about the blade, I should use your diagnostic system for my life!

Thank you! I had adopted my usual tendency to over complicate things with my very slightly wobbly table saw blade issue until I found this video. Thankfully, I didn't need the diagnostics as you'd petty much already done it for me and it turned out that all I needed to do was remove the bushings, clean them up on a 2000 grit diamond stone which removed the very tiniest of burrs and now the blade is back running like a dream.

I tried this and it worked, saved me changing the drive gears and bearing which I was going to do. Saved money and time. Cheers.

I messed with my saw for about two hours today before I decided my new blade was garbage. I bet this is the issue. Very helpful.

Today my miter saw showed the same problem. You have just saved me from buying a new one. The washer will be much cheaper for sure. Thanks a lot.

You helped me solve a long and on going problem. My dewalt saw had the very same problem and now I was able to fix it! Thanks!

That's very nice of you to share this diagnostic. You can also use a threaded rod and screws it into the harbor. And you will see how much bed your bushings are

Excellent video! Great job of explaining in detail each step with quality video angle to suit! I'm having the same issue now and was ready to chalk it up to the arbor bearing! Hopefully its just the arbor bushing! Thank you.

Thanks for that explanation and your video. That means a blade wobble also points to braking as a safety issue. You can also put the two washer plates face to face and hold them up to light. Slowly twist one of them.

Awesome, absolutely awesome. My blade has a slight wobble. I will use this to diagnose the problem. Had a kickback on my dewalt slider and it has not been cutting straight since.

I've not even checked mine yet, headed to the shop next, but this is excellent and very helpful info!

I really appreciate the video, really just made my trim job go alot easier and nicer looking

Nice one. Appreciate time and effort you put in this

great video, thanks!

Very methodical and enlightning. Thank you sir. One variable at a time to deduce the cause.

even if your saw and blade are new you should position your blade with the least amount of run out. Most people with just put a blade on and go. all saws and blade combo have runout and you can minimize it by finding the best postion for the blade and bushing.

Very helpful! I will be diagnosing my Makita LS1016L this weekend...hoping I can find a similar easy-fix

I just grabbed a DW716 at work that was being thrown out because of blade wobble. I removed the arbor washer that you replaced and put it on the lathe. I measured .004 run out on the small diameter register. I took a carbide lathe tool and cut the .004 thousandths off of it. It runs very true now.

Very helpful, thank you.

Thanks - saved me a lot of time.

Hi. Thanks for sharing your video and being able to help so many of us watchers. Please see if you could help me too. I'm in the process of acquiring a Dewalt DWS709 15 Amp 12 in. Slide Compound Miter Saw that according to the manual, the saw comes with 5/8" arbor on it. Then I have to replace the blade for a Freud, like the one on your saw, but I don't know if the bushing is supplied since these Freud blades come with 1" holes on them. Therefore, my question is if your saw has the same characteristics as mine (5/8" arbor) and requires a bushing to install the new blade, or the factory blade has a 1" hole and the bushing comes with the machine already? Also, since this seems like a persistent problem with this bushings; would you please include the store's name or link where to purchase it? I"ve tried to locate it and only find one place but they want $19 for it plus S/H. Please help me with this issue? Thanks.

Tnx for sharing this vital info, tnx bro!!

Thank you very much. It was a very helpful video.

Thanks for the video! I have a 10” craftsman and both bushings were identical. I was able to put the back bushing in front and move the front to the back. Problem solved!

I have a Ridgid R4221 that I just setup (a gift from several months ago that I finally unboxed because of a couple issues with my DeWalt 10") and discovered the wobble issue the moment I switched it on... huge disappointment for an otherwise superb product. I just found your video and had surmised the saw's wobble issue may be either a harmonically induced problem or perhaps could be a blade balance issue (not too likely) but trying to be open minded to all possible sources which I surmised could be drive train induced be either motor bearings and/or bushings due to the worm type transmission of power to turn the blade. So, watching your well done trouble shooting process makes me all the more inclined to believe it to be the later sources which I suppose could be a cause of harmonic vibration as well but a $5 bushing is a pretty cheap place to start if Ridgid kicks my claim due to being a gift and not having a receipt to register it for their LSA warranty. I'll try. We'll see. So, where do I purchase a 1" arbor bushing these days... for Ridgid? Also, I've wondered if putting a 1" rubber shim washer on each side of the blade might serve to dampen the vibration? Your input, plz.

My left ear really enjoyed the video.

Awesome video. Thank you

I just replaced my blade and it started wobbling. Well, watching your video I realised I was missing the washer that sits on top of the bushing. Popped a new washer on and it's back in service.

Awesome work! I am new to this and the tools associated with wood working. Been a mechanic for years and frankly grew tired of it. Just bought a Rigid r4221 if I am not mistaken and a common complaint is blade wobble. Hopefully mine is minimal or nonexistent.

Thank you!! this fixed my saw

Thanks! This was exactly my problem.

Thank you very much. You help me a lot.

Thanks for the vid my left ear learned alot 🤣

great job..... many frea the wobble.... but i think u gave hope.... to the eobble generation.... !

I can't figure the problem I have out. I have a ls1013 makita, when I let go of the trigger the saw doesn't brake and it sounds like metal grinding, not a squeel but like it's a metal moving part skipping and grinding on something else while it winds down. I haven't found anything at all like this on the KZfaq. The gear inside the housing is a little worn (it has a lot of miles on it though) but besides that everything looks fine. Would a new switch fix this by fixing the brake.?

Friendly observation: if you have an indicator using it would make it easier to find the high and low points of the wobble. But, it also might trigger your perfectionism as you try to fix all sources of wobble in your saw (I'd get stuck doing that if I didn't catch myself). Anyway, great video. Unfortunately my saw has wobbles for a different more structural reason. But this is great info to know if something like this ever happens to me.

thank you sir very helpful... so I can fix my tablesaw

very interesting,thank you

This was great i couldnt figure out why my saw was out of tune from the left side only... Because of a 16th of wobble from a dirty bushing... Also i have the same saw and i sprayed three coats of leak seal on the underside and arm and then filled all the gaps with spray foam, then worked all the extra foam smooth, thenn another three coats of leak seal... My saw is so quiet now its unreal, plus it doesnt get full of dust

Great tutorial, thank you!. If the bushing is the most common cause of wobble, could you start your diagnosis there and save a couple iterations of taking the blade off and on?

Thank you for the video sir have the same problem in my miter saw .. thanks

No safeguard you are my hero.

Jeeez, that's brilliant, how long did it take you to figure it out? My Makita has a blade wobble, thought it was because the blade was pretty old but I'll do this test at the weekend, hopefully they're all made pretty similar with washers!!! Cheers for info 👍

thank you

Tk -you... !!! You video helpme to save big money

Hello, are you able to tell me if the blade would wobble like this with the blade at full speed? Thank you!

Great video an well done with ya investigative persistence, but with today’s precise technology an engineering you would have thought this wouldent happen with this sort of tools , the cheepie ones ye maybe but not the high end market like dewalt, makita an so on , thumbs up to ya thoe mate 👍

Nice. I will test with a new blade and if the wobble persist I will check the bushing.

Thanks for this! Extremely helpful. Where did you order yours from?

Hey I just picked up similar saw ..doesn't have the small lil washer that sits on the arbor ..is that necessary?

very interesting video. ordered the new bushing and my problem still persists. what were you going to check next? any ideas on how to go about this?

thanks man big help ❤️❤️❤️❤️👌👌👌👌👌

Thanks. My problem was, I dropped the spacer into the blower. Also, is that a diablo 8" blade by chance?

I HAVE DIRT IN THE BUSHIG SO I JUST HAD TO CLEAN IT UP THANKS A LOT

I have had small pieces of molding, after I cut them to fall back into the teeth of the blade and then get caught. How common is it to actually ever so slightly knock the blade out of balance? I only use full kerf 1/8” thick Freud blades.

Thanks!👍👍 Hopefully it's just the bushing on mine also....

Thank you sir. I was about to trash my saw...

I just bought a Dws779 double bevel sliding compound miter saw. Which gives me two cuts when set too 45 degrees to cut molding. It gives me the 45 and also give me 15 to 20 degree cut. Does not cut straight.

Good video. I think it's funny you talking blades on saw and your missing a finger lol.

So what was you doing to lose the finger

Great video, I just got a dewalt 713 and it does not cut true, meaning making a simple cut at 45 deg, when looking at the cut it's not straight.

It still looked like you had a very slight wobble after you put on the new bushing. When you turned the blade a small gap appeared and then went away, so you still had a slight problem. It also looked like you lost the end of your index finger on your left hand, miter saw injury or table saw? Ouch! Sorry you lost that part of your finger. Thanks for the video.

I went through all the steps explained in this video (great video btw.) But on mine the X continues to be the closest to the piece of wood , no matter which way i turn the flange, bought a new flange(original makita part) but same problem Can somebody give me advice as to how i should fix this? Its a makita LS1216 thanks

Where did you get the part?

My lock pin to lock my saw blade down appears to be broken... this was my husband's saw - he passed away and now it is mine. He was not proactive regarding "tool maintenance" so I am left to figure things out. The blade is currently in the "locked down" position and I cannot get it unlocked so that I can use the saw - any suggestions? Thank you.

Not sure if i want to take advices on saws blades from a guy missing a finger! I’m just kidding!..... thanks for the advice mate!

Yes I did try the manual plus the u tube videos. Did not work. Plus the blade change. Dewalt double bevel compound miter saw. Brand new , wasted 3 days trying to find out what was wrong. Lost a small Job to install molding . Cause of the piece of junk saw. I ended returning the saw for a refund. But lost on the other parts I bought for it. In trying fix what should of been right from the start.

Basically change the washer.

Had a bad bushing right out of the box

Sooooo... What in the world caused that old bushing to wear so drastically? Was the saw run for awhile without adequately tightening the blade? OR Is this just what happens over time with use?

Mine wasn't as bad as yours, but it was the bushing just like yours,,,, sigh of relief!

Looks like someone is missing a finger tip. That had to hurt.

my dewalt slider won't rotate all the way to 45 degrees. I slid the fence out of the way too. doesn't appear to be hitting anything. any ideas??

Good video and good troubleshooting. I ordered my first miter saw and it is coming tomorrow. Do all the miter saws have left handed blade bolts

I have all dewalt but I will not be buy there miter saw probably makita

Here is how you can fix that problem HERCULES 12 In. Dual-Bevel Sliding Compound Miter Saw With Precision LED Shadow Guide

See'in that finger of yours I bet you got it unplugged. Every good carpenter has at least part of a digit gone. Be safe everybody.

Short information

The Problem stems from ALL Imported/ Chinese manufactured tools , That their QUALITY CONTROL is NOT like AMERICAN made products . AND their Materials are of NON Virgin Manufacture. Ive seen this problem Grow over the decades in the Machining industry I have worked in over 50 Years . Asian quality Control has improved some , but No where Near what it needs to be . That Washer (Bushing) he replaced was most likely "stamped" NOT Machined during Manufacturing . And Or was never inspected for Quality Assurance. Old saying IS YOU GET what YOU PAY FOR .... Enjoy ! Glad you were able to Find the Culprit : )

It’s not a bushing though, it’s a collar. Why did he waste all that time placing x and turning the blade and whatever. Yet another video showing that dewalt is rubbish.

STOP MOVING YOUR REFRENCE WOOD!

So, spend a little more and get a Bosch and avoid all of these problems.

Thank champ ! OUCH ! The finger.

great video, thanks!
