DIY Ball Bearing Lawnmower Blade Balancer

amzn.to/223o3LE Please click the link to see the selection of magnets. They are great for all kinds of needs around the house and shop. Make sure they are neodymium mine are and are super strong. In this video I use a suggestion from one of my longtime subscribers A. LeBlanc to make a ball bearing lawnmower blade balancer. Disclaimer:

I received the package Monday for the blade balancer. This will come in so handy. We cut over 5 acres of grass. Can't thank you enough doublewide6!!

[@nicholas8479]

I appreciate your effort. Two suggestions: 1. remove all grease from bearing and install a little of thinnest lube you can find. This will make bearing turn easier and your device more sensitive. 2. Maybe you can use cone of first device on your device to help center blade.

[@aleblanc3547]

Not only are you so much smarter than your tools, you have mad engineering skills Doublewide. Thanks for this invention...I'll be building one just like it.

[@doublewide6]

+A LeBlanc Thank you. Please post back how the build goes. Thanks again.

[@aleblanc3547]

Will do

[@doublewide6]

+A LeBlanc Hey I was just looking at router bearings and you could order a set of them and stack them like a pyramid to fit any blade you have they make all kinds of sizes. Follow the video link to Amazon search "router Bearing Sets"

[@arciefan]

Excelllent work and ideas. Couldn't help but notice the release rope on the garage door. I removed mine and did the zip tie trick. After watching 65fords video of how easy it is to grab that rope from outside, decided to take care of that situation before hand. Thanks for the nice video!

[@pumpkinpeanut1]

I really learned a lot from this demonstration. This project seems quite accurate. I've gotta try and create one too!

[@curiosity2314]

Excellent invention and or DIY adaptation. ! Never even thought about balancing a lawn mower blade.

[@doublewide6]

+Curiosity If they are way off they will break your spindles on a tractor or cause vibration and oil leaks from the bottom seal of your engine.

[@jerrydineen2827]

That is a wonderful idea and demo. Thanks for sharing with us.

[@michealcook1729]

Very impressive project. I have the MagnaMatic one. Never would have considered building one. Until now. Keep up the great work.

[@doublewide6]

+Micheal Cook Thank you. I built it for fun. I will probably use it about 6 times a year, but that is okay I enjoyed my time building it.

[@retrorestore]

Great little project. I have many of those magnets and yes, they are very strong but shatter easily. Good job.

[@doublewide6]

+retrorestore I had one shatter because I used it to help me hold some metal I was welding. They don't like heat.

[@GmGarlo]

i could see that being very accurate and at the fraction of the cost, love these kind of tips THANKS!!!!

[@doublewide6]

+GmGarlo Thanks for commenting.

[@victoryfirst2878]

Now I will make me a balancer that costs me just about nothing. Thanks fella.

[@Lanninglongarmmowing]

THIS. IS. AWESOME. We have both types of blades and I never trusted those cone balancers. Great video!!! Thanks for making this. I'll have to try this.

[@doublewide6]

+Love2boat92 Please report back how yours works out. Thanks for commenting.

[@Lanninglongarmmowing]

doublewide6 I will try to if I get around to making it. Lol. Welcome.

[@garybaumann5637]

Excellent. Thanks for the idea.

[@TheEffoff]

Look at you, dude. Fantastic.

[@rogerholloway8498]

Great idea! Thanks for showing us! Bring one over installed in a mower and show me how well it works too! :)

[@doublewide6]

+Roger Holloway Thanks for commenting again. Depends on where you live. Like your profile pic!

[@AltonRowell-gb1lb]

Great job dude.

[@ozzstars_cars]

Nice tool to have. Enjoyed the video

[@doublewide6]

+Ozzstar Thanks Man. I appreciate the comment.

[@CTmoog]

pretty cool

[@Rich32262]

Great job! My only observation is when you put the blade with the star opening on the jig it didn't fit snugly. Looked like about 1/32" gap. It looks like the blade would move to one side or the other of that gap which would surely change the weight distribution. Maybe the piece on the bearing would have fit the star opening prior to grinding it down. If so, I'm sure you have more stock of that pipe. Or something else to fit the star openings better.

[@shawnmrfixitlee6478]

Super great Idea man .. Thumbs up for sure !!

[@doublewide6]

+ShawnMrFixitlee Thanks Man!

[@johnmilner7603]

Good stuff.

[@doublewide6]

+John Milner Thanks Man. I'm happy you enjoyed it.

[@budmoore8144]

GREAT TIP GREAT IDEA

[@doublewide6]

+bud moore (buckshot32000) Thanks for commenting.

[@philliphall5198]

The old style works ok for 60 years but blade bolt patterns have changed a lot I use a extension in vice and 4 inch grinder, it’s fast enough for me

[@ncrdisabled]

I wish I had the stuff to build that.

[@joshslawncare4740]

What size or part number was that bearing? Do I just need to look up a 5/8 bearing

[@ITUMBLE4U]

What brand/model of drill press did you get? Thanks for sharing that great idea...my drywall screw method isn't very accurate.

[@doublewide6]

+ITUMBLE4U I got a Rockwell/Delta from about 1986. I made several videos on the restoration, and other things recently on my channel. Thanks.

[@MidwestMotoRider]

Dynomite idea one of those "Why did I not think of that" moments!

[@doublewide6]

+MidwestMotoRider Thanks, after doing a little research on router bearings it would be simple to order a set a bearings of different widths and mount like a pyramid, so any blades would fit a particular bearing.

[@MidwestMotoRider]

doublewide6 oh I love that idea. Thanks!

[@jerryf2426]

Great video, How do we know he hub the bearing is in is balanced? When you add the blade wt. that could make a difference.

[@doublewide6]

It is close enough, but if you rotate the balancer on a sideways screwdriver the balancer heavy side will point down. Drill the back of the heavy side out with a 3/8th drill bit. Hope that helps.

[@johnprenosil3945]

Holy crap. It's a lawnmower blade not the space shuttle. Hub, as built, is adequately balanced.

[@philiprizek6384]

Do you think magnets out of it DVD and CD-ROMs would work I know I can get my hands on them I just can't go down to the local store in like I need some rare earth magnets

[@jasonmushersee]

you have all nice tools. how much horse power is that bench grinder?

[@doublewide6]

+jasonmushersee The small grinder I used to ground the ring is 1/3HP and the big one at the end of the video is 1HP with 8" wheels.

[@raymondcampbell2346]

Great job. I will be making me one. Where can you get the bearing you used? You said it was a router bit bearing. Donyboy73 did a tool review on a blade balancer which is good, but is pricey.

[@doublewide6]

+Raymond Campbell The bearings are on Amazon. Please follow my video link to Amazon and do a simple search for router bit bearings. Freud and Whiteside are decent brands.

[@raymondcampbell2346]

OK thanks.

[@UpWithLife]

It is a #1602, 1602-2RS,1602RS Premium Sealed Ball Bearing, 1/4 x 11/16 x 5/16

[@jaydee123ish]

Yer a freegan genius

[@dontblameme6328]

The blade should NOT hold wherever you place it on the balancer. It should rotate to rest at perfectly level. Your bearing appears to have some internal friction.

[@340rps]

There goes a finger or hand. God man use a stick or something! .... Good job on the project, beats paying $100.

[@surferdudemi]

Def should use a pusher on a table saw and not get fingers that close to the spinning blade

[@432THz]

Good way to lose some fingers bud. Use a push stick.

[@340rps]

Just a matter of time! We had an old 3 in 1 table saw, sander, planer. My brother in law was cutting a board which kicked and his finger went into the planer, finger was a mess as he lost the tip.

[@notdirtyflics1067]

Didn't somebody make that for you

[@Affendog]

an impact driver is best

[@doublewide6]

+Affendog rather than a screwdriver? Wider the shaft more friction equals less blade movement. Bearings are wide, but the friction is removed.

[@scarey2me]

If those magnets are even slightly out it will render that device useless. Even 1mm out or if one magnet is slightly lighter or heavier than its diametrically opposite it will not work correctly. That wooden block is your achilles heal. Are you sure that centre hole was drilled in exactly the centre of that block. You have introduced so many variables that will cause you grief with that design. I bet you didn't get all that grease out of the bearing either. Watch how it wobbles when it spins. Nice project, but it is no better than a nail in the wall.

[@condor5635]

Nice idea and was enjoying the video until I cringed at your safety approach. You need to learn how to properly rip wood / using your hand like you do against the rip fence 1:15 is asking for trouble. Additionally understand blade height! Push sticks sitting on the fence! Please learn proper safety tools and techniques so you will have all of your digits to use your balancer. Thanks for posting. Enjoyed end result

[@urdulearner8221]

But why balancing those blades is that important ??!!

[@nicholas8479]

minimize vibration.

[@BeachRumminbummin]

it makes the mower feel and sound like it's destroying itself.

[@terrylarotonda784]

Watched your video and I wanted to build one. I made mine out of aluminum using 1/2" needle bearings. Check it out on my FB page under my name Terry LaRotonda. I would appreciate your comment. Thank you for sharing this little tool.

[@Dr.Stein99]

Not sure how important it was to watch you cut 2 pieces of wood on the table saw without using a fence.

[@condor5635]

Erich Stein - you mean push stick. Extremely dangerous technique. Blade is way too high for the cut and his finger are inches from the blade ripping small pieces. Funny the push sticks are resting right on the fence. Careless and sloppy. Hope he really understands the danger here

[@nelsoncomputer3169]

@@condor5635 Couldn't agree more. I almost stopped watching it just because of the lack of safety. Good idea on balancer, poor procedure to make it.

[@myrond3588]

Never a shortage of safety nazis on social media these days. Glad it makes you feel important.

[@peopler2stupid165]

Curious as to why you would waste time finding the center of the board with your try square when in reality it made ZERO difference, You were only using the center core you drilled out. You could have simply put the hole saw in the drill press and guessed where the center was and drilled it in seconds with exact same result. (Assuming you were trashing the board you cut the core from, there was no point to all the accuracy in where to drill.)

[@condor5635]

peopleR2stupid - I was thinking same thing - reason is to locate precisely the 4 magnets hole locations. If they aren’t precise whole jig is crap.
