[@diligenceintegrity2308]

Mathias, I love your use of good measuring devices and your accumulated knowledge. I never case to be fascinated and learn. Can't say enough thanks for your excellent work.

[@y788lhjk1]

Aww the little helper is so cute.

[@jackblack4359]

I really like the way you approached and finally assessed the problem you were having.

[@kaden56]

Thank you for doing this video! You were so methodic about how to test and fix and had so many good ideas on how to cut down vibration. I think many of the things you did could translate pretty well into a lot of different machines. Great work I love your bandsaws!

[@nelioquintela]

Excellent work Wendel, I've already built several machines and I know that Alignment and balancing is critical to good performance. Congratulations, your project was very good.

[@williamgreazel8715]

My favorite video, not because the content was any better than your usual very good stuff, but how patient you were with your young assistant. She is your best "project " so far. Can we assume that someone who thinks two bandsaws are better than one , feels that same about assistants?

[@benchtopwoodworks]

I think you nailed it near the end, apparently your motor speed is just very close to a harmonic in your saw..maybe changing the speed through a different drive sheave could help. Great video, it's inspiring that you continue to troubleshoot and show your logic for us all to follow, part of what makes your videos so enjoyable and great for other's to learn from!

[@nedimyildirim6107]

I appreciate your willingness/dedication for solving troubles. great job.

[@95thousandroses]

Man I love it when he shows his process. Great vid!

[@marceaton3128]

I think it is the green paint. Also, your little helper is adorable.

[@toompie69]

No matter what kind of video you make it's always fun and interesting to watch :)

[@JohnHeisz]

Was hearing the "Mission Impossible" theme there at 1:30 :)

[@FortuneZer0]

Not so loud, else the copyright strike takes this video down.

[@lilvegee]

hi john u ever smoked weed? xd

[@petercollin5670]

John Heisz I was thinking more along the lines of "these boots are made for walkin'"

[@tolsen77]

I heard "good vibrations"

[@JohnHeisz]

Vexy 420 Yes, but I didn't inhale.

[@MmmmCheddar]

Thanks for walking us through your troubleshooting process. Another excellent video.

[@anicecoldbepis]

It's shaking too much. Clearly you need to make another bandsaw

[@jantoman2279]

And much bigger.

[@anicecoldbepis]

That was implied. I wouldn't object to a tiny bandsaw though, It would be something I'd buy the plans to.

[@lumspond]

ThePetahs I'd love to see a tiny bandsaw project. Something for model makers.

[@reaper1874]

Ya, 0.001" to 0.002" of vibration. The thing is junk. I will volunteer to take it off his hands. ;)

[@volundrfrey896]

+lumspond Are small ones really worth the time it takes to build it? You can get a new one for $130.

[@stetsonator]

The cutest apprentice I've ever seen! Great job mom & dad!

[@tonyr2365]

I CAN'T EVEN RIGHT NOW. I'M LITERALLY SHAKING.

[@zippymax1]

Mitch Robinson: wedge a shim under your motor.

[@AGibbs93]

This is perfect timing. have gotten my bandsaw up and running and been trying to figure out ways to cut down the vibration. Thanks Matthias :)

[@greenkitty6482]

Good to see Rachel and Harriette; thanks for sharing : )

[@OgMandin0]

A possible remedy is to place fiber washers between the casters and the saw. (Have seen them used under clothes dryers before.)My reasoning is if the casters dampen the vibration the saw resonates, a little bit more cushioning might dampen it more. Here in Greenville, SC, a 100 year old supply company survived selling 3M fiberglass reinforced rubber pads to go under heavy textile machinery. Machines which vibrated like pea thrashers.(They repackaged the product and obliterated all 3M trademarks. That way, their competitors were unable to source it, and undercut their 300% markups.) Internal machine vibrations which reverberated through the bases of machines got dampened. Machines ran more smoothly. If finding such washers is a problem, buy some HomeDepot felt furniture pads Drill/punch a hole and place a pad just above each caster. 1/4" might make a big difference. No down side. GOOD LUCK!

[@DoRC]

a suggestion, when balancing using bearings, pull the seals of the bearings and clean all the grease out of them. greased bearings add a lot of friction and make it really hard to figure out where the heavy spot is.

[@SamanthaDowns]

Such convenient timing! I am yet to solve the vibration issues with my own homemade bandsaw and there was a lot of useful information here for me to do some more trouble shooting :)

[@glendavis9123]

Thank you for sharing your shake problem and very systematic problem solving in attempt to get to the root cause of the problem. I would suggest at this point to consider using a stethoscope to probe the machine to see if a sound can be heard that corresponds with the deflection. Still,,, a thou of deflection is phenomenal when you consider the weight of the machine and materials used - you are inspiration to us all.

[@pctas5]

me encanto ver a tu señora y a tu hijo ayudandote Muy buen video

[@F-Man]

You are the da Vinci of woodworking, sir!

[@ecahseb]

Ferrariman601 da Vinci was the da Vinci of woodworking

[@fbiker79]

ecahseb best comment ever!!

[@12345NoNamesLeft]

No, da Vinci never made anything. All he did was sketches.

[@berthosquire]

That's not correct. Google da Vinci sculptures and educate yourself.

[@benjaminbrosdau1626]

Awesome to see you here Ferrariman601! Loving your Asetto Corsa vids!

[@fuzzy1dk]

you could check the roundness by sticking the dial indicator on the blade where it goes around the wheel. I guess how square the wheel is to axle could also cause vibrations but that would probably be in a different direction

[@muneef007]

please make a shaking comparison with a factory band saw.

[@adriantrain2037]

Love seeing that having your daughter in your shop with you as being no problem. My son is 6 now and hes my right hand man, weather im metal working, forging, work8ng on cars and now learning wood working hes always right there with me, always doing what dads doing..... but man does he love electrical tape, i always have to have seceret stashes of it incase i ever need any..... but i love every minute in my shop with him... this has been a great set of vids. Keep up the great work.... i always learn somthing watching your uploads.... cheers from Australia

[@TK-qu1ht]

Your Assistants were awesome!

[@hpy-yl4px]

I really like all of your work.. and your special way to explain..

[@joshuac1364]

Good job isolating that issue. it takes a lot of patience and trial and error to fix that

[@gkumar9534]

You are a genius sir. With love from India.

[@j.davidwilliamson1163]

Love your helper, she is so cute. Also your work is fantastic.

[@peckis2]

Beautiful baby, nice to see you getting him involved.

[@dozer1642]

Your helper is adorable.

[@zyspan]

Your child is so beautiful - wide-eyed and taking everything in :-)

[@DonJohn87_YT]

The level of cuteness is off the charts, especially for a Matthias Wandel video ^^

[@zippymax1]

yep...that baby tho

[@mickenoss]

Those weights on top of the saw make me nervous for the little tacker. =)

[@DonJohn87_YT]

+mickenoss Agree, and it also looked a bit too temporary of a solution. Adding some mounts would fix it.

[@elmore-mtview3473]

I saw the "beating" (slow oscillation in amplitude) in your measurement and thought of the pattern created by the interference of two similar frequencies. So the beat frequency equals the difference between the two driving frequencies coming from the bottom and top wheels.

[@AtomicShrimp]

I wonder if it would be possible to create some sort of compact tuned-mass damper to defeat the vibration...

[@DanLokar]

I would love to see your take on a Hand Spinner. Very simple concept and it seems fun to build and use!

[@johnrgmcmenamin]

Very cool to see you go through your problem solving method. I enjoyed the video!

[@jimintaos]

A while back I had a blower fan blade I needed to balance and came across an article describing using parallel and leveled straight edges to support the fan shaft. This offered much less friction than using bearings and the set up was very sensitive to the blade balance. I didn't have any metal straight edges at the time so I used a couple of new 6 inch blades from my floor scraper. Scary sharp but just about 0 friction.

[@aboamiaer1863]

رائع واشكرك على ماتقدمة ولديك عائلة لطيفة brave ........ Fantastic

[@campbejouc]

the kid has a real interest in the process and the wonders of the tool drawer

[@stevehogg]

As usual, my trusted source. Great video.

[@fimbles1015]

Great tip for checking the roundness of a wheel by twanging the blade :) Great video as always. Thanks :)

[@dessertman1181]

Your a mad scientist and your videos are great!!!!

[@NOLAMarathon2010]

More videos with cute kids! More Rachel!

[@59seank]

Your little helper is growing sooooooo fast!

[@newfization]

This may sound odd, but it's a technique I've used many many times to chase down vibrations (used to be a ski lift mechanic and millwright). Take a long screwdriver with a hard handle and while holding the handle to your temple, press the blade of the screwdriver to the problem unit, checking in various areas. You'll quickly close in on the problem by feeling the intensity of the vibrations, hotter colder style. We called it a mechanics stethoscope and used it to check bearings on lifts, cats, pumps, you name it. Hope I explained this well enough.

[@markkalsbeek5883]

I think this is great advice. Any rigid and dense object will work, but an actual stethoscope would be the best, though.

[@matthiaswandel]

they make stethoscopes for auto mechanics. Same idea.

[@jamesmitchell5013]

That's quite the little helper there Mathias!

[@jeric_synergy8581]

Very interesting. Thanks for walking us thru the process.

[@magicrobharv]

Practical advice balanced with adorable cuteness !!!

[@jhtnpa]

I enjoyed your troubleshooting...well done as always!

[@pedromariz2840]

1st Newon's Law showing up! Great Job Mr Matthias! Now it's Tuned!

[@newmanm144]

Check run out both on the face and the running surface of wheels with dial indicator, being timber there might be a little anyway, but you could identify a wobble or flat/high spot.

[@SeanHodgins]

How about some dampening feet? Does the RPM decrease at all when cutting? Does that increase vibration amplitude? All the test were done with no load, so maybe there are no vibrations when you're cutting(or they're worse!).

[@anderswegge6828]

Your QA assistant is starting to look real cute. I hope we'll get a chance to see her from time to time.

[@boobye6305]

It's shaking because it's groovy baby!

[@ldwithrow08]

I have had turned wooden pulleys run out of round due to uneven wear. Also V-belts can develop worn spots you can't even see that will induce vibration.

[@thecynic807]

Holy cow how time flies. She's getting so big.

[@18roselover]

I have a similar problem with my 20 yr old scmi mini max s -45 18in BS the top cast iron wheel was out of round. by .025 My machinest friend said it was to difficult to true up the wheel. I/ll make a check list of all your suggestions .Thanks for posting . Very helpful

[@Infamanious]

i'm surprised you didn't add a dampener under the wheels such as a rubber pad. It's also fascinating that, for instance, if it gets warm in your office, the humidty will be in a higher level of your room, thus increasing the moisture content of certain parts of your equipment. ( since theyre wood )

[@WildmanTech]

I really enjoy your scientific method.

[@DBYNOE]

I tried to read the comments before asking, but gave up after 20 or 30 as I am on a smartphone. I was wondering how this level of vibration compared to a typical commercial unit? Also, I saw several mentions of the belt, and remembered that those link belts seem to quite down tablesaws a bunch (I have a very old Craftsman Flex Shaft, so I never got to try one), also, I also seem to remember that one of those wheels had the glue lock up before you finished straightening it (of course that could have been someone elses video building with your plans :-). I love seeing your family in the shop, it is more than delightful.

[@CPBuilds]

I bet that Dewalt saw vibrates more lol. Interesting video. Your daughter will be making her own bandsaw in no time.

[@burntsider8457]

Interesting analysis. Could uneven gathering and stretching of the tires contribute to vibration

[@ilyaivanov1745]

Helpful videos,Matthias.

[@dondonaldson1684]

Matthias, I agree with you in your article that it is probably the V-belt that is the issue. Observing the resonance effect, I believe that your V belt is the transmission source of the vibration (dial indicator varying up and down while running, and going through an obvious resonance peak while slowing down). You obviously believe it is resonance as you instinctively added weight to the frame to alter the damping factor like any good U of W engineering grad would do. Part 2? Thanks for all of your videos, I enjoy them all. D

[@martijnbeulens2241]

Wow, your kid grows like fast, nice to see.

[@rix0r222]

Maybe it was harder to hear when you recorded the video, but I heard a very clear change in pitch when you were plucking the saw blade after adding the paper shims to the wheel. Almost a semi-tone difference. I didn't really hear any change when you were plucking it before (indicating your wheels are quite circular).

[@pragmaticmansboots]

You didn't compare the vibrations to a store bought model, another great video.

[@BerraLilltroll]

The best. Thx a lot for the insightful analysis.

[@mickenoss]

Could you use some like 5mm threaded bar to tension the upper part of the saw, a little like the way a truss rod works on a guitar neck? ...just a thought.

[@Charl133]

good day Matthias could the vibrations be caused by the blade not being joined correctly?

[@ascenciongarciarosales6303]

mathias que tal ¡¡¡ como estas me parece excelente la cierra cinta ,soy de la tierra donde nació el tequila me dedicó a la elaboración de muebles

[@wonkamaster101]

Love your videos!

[@pauldoyley8354]

Definitely a correlation between the vibration on the dial mic and the audible of the motor. To me it almost sounds like the motor strains and you get 4 distinct vibrations. Any chance the drive belt has a hard spot or is flat? Or maybe the bandsaw weld going over the feed rollers?

[@EggiF]

My suggestion is, that it depends on how the two wheels are positioned to each other. In my mind that could influence the whobble frequenz of the saw.

[@sciencetoymaker]

Very thorough; I learned something today. You'r helper is so cute!

[@sportlol]

I feel like i heard a little variation on the pitch, but could be an audio issue from the video, check with a digital instrument.

[@DavidSteinkuhler]

i was thinking the whole time it might be the casters and the entire base. you did cover that part though. i thought you said that the plan was to build a bigger base at some point?

[@drunkramen]

Never thought I'd see Matthais play the upright (bandsaw) bass. Nice vid, haha!

[@ithinkillmakeit7243]

I wonder if a link belt or different belt on the motor would make an improvement on your dial gauge reading

[@stevensexton5801]

That damn Spring Mass Damper stuff gets ya every time.

[@WoodenCreationz]

You get a similar effect in your vehicle when you hit a certain speed and your missing a wheel weight... The whole car starts to shake... I think your right.. if you slow it down or speed it up.. You will probably break free from the shake and become stable. Curious if you put rubber feet or shocks on it.. if it takes out vibration. All and all... Great video bud.

[@littleshepherdfarm2128]

Mathias: So glad to see you finally got a helper. LOL. He's too cute!!!

[@longshot789]

I dunno, the change in pitch seems pretty obvious in the video. Sounds like 3-5 half-steps in pitch.

[@CoverCatz]

Matt you are awesome bro I love all your videos

[@stanleyjones2085]

You are the man Matthias !!

[@erinboatguy]

i just made a tiny Newtons cradle (5 ball bearings on strings) and it would not work correctly until i mounted on a sturdy secure base something about bodies in motion canceling out the kinetic force or something.....any way something with moving parts needs to be on a super sound solid base

[@lpmay4388]

How much does it vibrate with the blade removed? Would removing the blade isolate any remaining vibration to just bottom wheel balance/motor mount defects?

[@10OZDuster]

so the dumbbells is going to be part of the build plans ?

[@camarosteve312]

I was getting some vibration on my 16" that i traced to the belt. i made a simple tensioner with some skate bearings and that helped it quite a bit

[@scothargan7002]

I wonder if rather than leaving weights attached to your bandsaw, could you damp the vibration by attaching a cable with a tensioner mounted to the top section and the riser post in the middle? I think the spring in the cable would change the resonant frequency of the saw.

[@MaartenBakker]

Hi Matthias, maybe you could also check your wheels with the measuring tool on the surface without the rubber lining. It might verywell be your wheels have a slight oval shape which could explain the cyclic bouncing effect of your readings.

[@elmore-mtview3473]

Do you get vibration without saw blade (turning lower wheel only)? Can you swap wheels top to bottom?

[@MrManolismo]

very informative, keep up the good works. thanks you

[@m-m8835]

Would a thick rubber mat underneath the saw do anything to damp vibration? Seems like you already have it at a manageable level.

[@knightwoodworkingusa8557]

Could you do a video on a plate holder that's 3 x 4 ?Trying to do a spinning plate rack. Greetings from California

[@mealex303]

does the weld joining the blade make any unwanted rattle / wobbles?
