Thanks to all the all the good eyes spotting and pointing out that it's best to remove all previous weights before balancing/rebalancing. Now a question that's often debated for you guys, is there a limit on weights used per wheel? Leave your opinion in the comments!

[@Bozemanjustin]

You definitely want to remove all old weights before starting If you noticed your weights were opposite sides of each other so you were fighting other weight Absolutely unnecessary I balanced tires full time for 3 years

[@prorityfeed3210]

Even with the balancer as is from HF, you can spin the tire while it's on the balancer and get a really good idea of where the weight needs to go by watching the bubble as the tire rotates.. And once the weights are placed correctly, the bubble may not stay exactly in the center while the tire rotates, but it will wobble about the center evenly. Spinning the tire and watching the bubble while it spins is more accurate than just letting the balancer rest, as there is that margin of error at rest because of the friction, as you point out in the video. I like your mod, it's super accurate, but for those of us with work vehicles that don't have to be super perfectly accurate, the spin and watch method does work pretty good.

[@RadRidesByCru]

Interesting you mention spinning the tire... seaside garage has a video on a vintage spin balancer machine that used paper instead of a bubble but worked on the exact same premise as your method. Good stuff!

[@leh3827]

I read never to spin the wheel when on a static balancer; it wears grooves and puts etc..

[@mrfester42]

This what I call "ingeniosity"! It's one of those things that once you see it, you think to yourself that it's very obvious and you should have thought of it yourself BUT it's not that obvious. Great solution!

[@stewartsmith1947]

The correct way to balance a tire with a Bubble Balancer, per Goodyear, is to use 4 equal weights . Place wheel on balancer . Get 4 weights of equal value. Place two weights left and two weights right on the high side . Move the weights away from each other till buble is centered . Mark with yellow crayon marker. Take wheel off of balancer and pound on inboard weights . Place wheel back on balancer and adjust the remaining weights ( will be close to craynon marks ) Mark them and remove wheel and pound on weights. I learned this back in the 60s from Goodyear.

[@lawrencejones4161]

That is correct Bought one of these in the early 80s sold it 5 years later and my friend still uses it Tools Work if you know how to use them. I bought another one a few years ago works great no mods.

[@peterrivney552]

I used if for my drag car tires and my buddy's stock car tires all the time worked great.. Best to not seat the tire so you can rotate the tire on the rim and sometimes you don't even need to add any weight at all or very little... Ass well do a "Y" balance for your weights eg: you tire is heavy at the bottom of the Y then add two weights at the top of the Y pattern so it balances out it is more accurate then right across from the heavy side...

[@MileytheJeepV2]

Yesterday i balanced my tires not knowing about the Y method and they were better but they shook around 70. Found out about the Y method ripped all the weights off balanced them again and i could do 90 without shaking lol i think thatll work

[@robbaird5972]

LOOK IN SIDE OF THE TIRES, LOOK FOR OVER LAPED RUBBER IN SIDE THE TIRE, THE LAPS SHOULD BE AROUND 5 TO 6 INCHES LONG, ANYWAYS YOU CAN SEE IT IN THERE, IF YOU HAVE 1 LAP OVER, PUT A LINE IN THE MIDDLE AND PUT THE LINE ON THE VALVE STEM, THAT WILL DIVED THE HEAVY PART TO BOTH SIDES OF THE TIRE, IF 2 LAPS DIVBIDE THE DISTENCE BETWEEN THE TO LAPS, MARK THE DISTENCE BETWEEN THEM, AND PUT THIS MARK ON THE VALVE, SO ON AL LONG AS YOU ARE GETING THE THE HEAVY PART ON BOTH SIDES OF THE TIRE, I DID THIS FOR A LONG TIME NOW, NO BALANCING NO LED, NOTHING, IF YOU HAVE RED DOTS ON THE TIRES, THEN PUT THE RED DOT ON THE VALVE STEM, IT'S THE SAME, BOB THE MASTER MIND

[@user-nk5xi4jw9g]

you can also use a ~1/4" drill bit to widen/flatten out the hole for the pin.

[@williamferguson395]

Hey thanks! I had just bought one of those wheel balancers and wasn't completely sure it was accurate! Seemed like you could stop the tire in an different spot all the time. Too much friction! I will give this a try!

[@mustangecoboosthpp3869]

You can drill the center hole so the point of the hardened steel is what the head is pivoting on. Just drill a little at a time until the head unit keeps rocking instead of stopping in three or four arc motions. Use a 3/8 drill bit and just a little bit at a time, you don't want to drill all the way to the bottom. Once you get the 3/8 hole deep enough the head unit will pivot on the hardened steel point and won't bind from friction. Here is my video on how to do this and best of all it is free. kzbin.info/www/bejne/qXi6eJewi9OjoZY

[@youuu4307]

Great idea bro 👍

[@pankajmakwana2300]

Thank you for the video, I think rather than the sharp point your steel ball will give a better reading. Rotating the tyre and watching the bubble in the centre would obviously give a more precise reading even if it requires tweaking the weights just a tiny fraction. Overall I think your ball method is a sure winner. Keep it up, it's great.

Just curious, does the ball bearing and flat surface need to be that large? I can't seem to wrap my mind around why it needs to be such a large bearing and flat surface...🤔 Reason I'm asking is because that piece with the recess in it that the needle balances in can be knocked out from the bubble side if you remove the bubble and spring leaving a place where the proper size ball bearing could be pressed or glued into the hole.

[@davet3937]

Just got the balancer and I noticed the pin is not centered and casting is quite poor on the machine. This looks like the trick to make sure the balancer is more accurate. So I have some modifications to do yet. Thanks for the video.

[@cal48koho]

[@maximusmax4557]

Do you think it would work just as well to replace the post that comes with the balancer with a length of round rod, with threads cut onto it? You'd just need a foot or so of rod, and a die of the appropriate size...

[@shiffroninc.4977]

Nice, I was hoping you would compare it to a spin balancer.

[@peterrivney552]

Myself I like the Bubble Balance better for my drag tires and my buddy uses my balancer for his stock car tires instead of the spin balance system the spin balance is faster but not as accurate Bubble Balance takes more time and if you don't seat the tire on the time you can rotate it to get it more accurate the seat the tire to the rim then do your balance big difference but a little more time involved that's how we used to do them in the '60's & '70's before the speed / time saving machines came out but there is another trick as well called the "Y " balance at the bottom of the Y is you heave spot then the top of the "Y" is where you put your weights it's better then a direct across Ballance...

Aside of this issue, it is still a static balancer. I wonder what happens, when you start rotating the wheel carefully - maybe by rotating the centre? Is it maybe possible to see a bad balanced wheel tumbling? 🤔

[@leh3827]

What a Great improvement to the original old unit!!! I'm taking your idea and running with a few changes. -I ordered the 1-1/2" stainless ball from your link except canada. -I am going to use the original base and vertical tube. -Place a 3/4" or 19mm socket (I'm going to use a deep socket but standard should work too) over the end of the vertical tube. The socket provides a flat surface on which to place a round rare earth magnet. I am going to try a 1.26" diameter magnet but as large as 2" diameter might fit in there without interference. -I might try 2 or 3 magnets stacked (should give about 1/4" thickness) to give more strength; I hope it's strong enough. -The surface of the mags are mirror finish. -Will be gentle placing the wheel on the balancer to hopefully avoid breakage. Those magnets can be brittle. If these mods work I might be able to avoid welding or gluing. Who knows? Maybe the focused weight of the rim (16" steel rim with 10 ply LT tire) will crush the magnet, in which case I will have to incorporate a steel disk on top of the socket. I will let you know how it goes! Thanks alot for your great idea! 'Y' Balancing is better than straight across, and split the weight between the front and back lips, or if stick on weights put them in the center of the rim. Another guy says after he gets the weights figured, flip the wheel over and install the back side weights first, then flip it back on the balancer to check again before installinng the front. I like the sounds too of how that guy balances them before setting the beads; just turning the tire on the rim to the best place, then finishing up with weights if necessary (sometimes no weights required!) It seems that maybe us commenters might have to reply more between us. Jim and Gunner must be too busy with other projects now.

[@AZsmoothrider]

Did the magnets work?

[@leh3827]

@@AZsmoothrider Yes a magnet worked. I put a 1/2" drive 9mm/3/4" socket on the existing shaft, then the magnet on the socket. I used the type of disk shaped magnet that has a hook threaded into the shoulder of the chromed body. I put the threaded shoulder down into the square opening of the socket; that holds the magnet in place on the socket. It works like a breeze without any welding.

How critical is it that the shaft is clamped perfectly vertical? Cause if it's not then the surface the ball bearing sits on isn't level and it might want to roll just from that. One way to test would be to purposely clamp the shaft 1 or 2 degrees off in either direction and see if results match.

[@mooosestang]

what is your opinion on using this for very wide wheels with deep offset? Is it still accurate enough?

[@bostig]

Great question. I would say no, with a deep offset, the bubble balancer is less accurate. The reason tightrope walkers use those long poles is that the dip down and lower the center of gravity, same for a deep offset wheel. The same mass wheel of the same diameter would be less accurately balanced on a bubble balancer than one with less offset until the point the wheel can't be balanced, and topples.

He needed 2 weights to balance the tire so, he just put the other one on the back. Most like to have one on the back and the front. They find out the total weight needed and divide by 2.

[@deanrantala]

The fundamental issue with these modern static tire balancers is the manufacturing quality. Look at Jegs, Northern tool, Harbor freight... they are ALL selling literally the SAME units that clearly came out of the same factory in china. And having owned 3 (from 3 sources) myself, I can attest that they all have the same manufacturing flaw. When these are manufactured, the balance head starts as a single piece of cast aluminum. After it is cast, it is placed on a lathe and the outside surface is machined down. The problem starts here. The part is either not being centered on the lathe correctly, OR the casting is so badly out-of-round that the machining simply does not correct things enough. TAKE A CLOSE LOOK at the adjustable bubble round on the top of EVERY ONE of these balancers... The bubble round is not even centered in the machined hole! Notice the thickness of the outer ring is thicker on one side than it is the other? Now flip the balance head over... notice the balance pad is centered with inner cast hole? If the outer machining is not on-center with the inner cast cavity, then you can easily see that the entire assembly is effectively not sitting on the pivot point in a true on-center fashion. The means: your tire is ultimately NOT SITTING ON-CENTER WITH THE PIVOT. Still don't believe me? Try this: balance your tire as shown in the video. NOW... lift the tire up and rotate the tire 180 degrees from the original position on the balance head. You will likely get a totally different reading. The only way to truly correct these balancers would be to [correctly] mount the balance head by the outside/machined surface and further machine the inside to bring the entire assembly into true round top-to-bottom. Ideally, you would then flip it around and also machine out the hole where the bubble round mounts as well. Finally, a large bearing would be inserted at a properly centered point and the entire head would be balanced: the heavy side would have a tiny amount of material drilled out from the underside to counter-balance any final in-balance that remained. Only then, would this be a properly machined, calibrated and accurate tool to check the static balance of a tire. Simply adding a bearing does little to correct this part of the issue because, again... the inner cast cavity is NOT ON-CENTER with the outer machined surface that the tire sits against. After buying 3 of these over 4 years from 3 different sources, I quickly realized they ALL have this same defect and likely all come from the same factory. I finally gave up and found a old used Micro-Precision balancer from the early 80's on fleabay (the kind that have an oil-dampened cavity and are factory-calibrated to the base/stand).

[@adamrogers3221]

I’ve also had the same experience. Can’t get the same reading twice.

[@socknetea]

not that quick if you had to buy 3 of them... its close enough for what's intended and plenty poeple attest to that, and this mod makes it even better

[@deanrantala]

@@socknetea On a full size truck/suv tire ALL of these will yield an imbalance of 1-2 oz. This is enough to make the unit essentially ineffective. "But so many people have great results with these". This is true. Countless people perceive "great results" every day from products that yield poor results. This is called "the masses don't know any better". This argument is functionally the same to hearing someone say "millions smoke crack every day and are just fine". That is also a true statement, but I am still not going to run out and smoke crack. The lobotomy worked GREAT for its intended purpose for many years, too. Thousands attested to it, doctors approved it. The bore hole on these is off-center. Period. The entire point of a balance is to... well.. BALANCE something. If it is NOT on-center, it can NOT be balanced. Period. These cheaper units may get the tire to within an ounce or two. And for many people, this may very well be good enough. But anyone using these for larger tires and especially anyone who is a bit more accustomed to vehicles that drive smother (and drive a LOT, especially highway) WILL notice a difference. I mentioned and explained all this because there is a functional reason the china sweat shop has not fixed this issue yet... Because everyone gets in line to buy these in ignorance and says "thank you sir, can I have another?". If enough people just started returning these - rejecting them. Bringing them back to HF, Northern Tool, etc... They would get the message and the factory would adjust the tooling (or re-tool) accordingly. Furthermore, the real fix for these is quit simple.. the factory simply needs to turn the balance head around after the outer surface is turned on the lathe and clean up the inside as well on the lathe. This would not only "center" the bore, but would also fix the "imbalance" that results from more material on one side of the head -vs- the other.

[@andrewcannon587]

@@deanrantala i agree, the best fix is done at manufacturing level, it's just quality control, nothing wrong with the design or concept, and better lathing doesn't cost that much more either.

[@lucheestiy2]

I did not mess with it too much. But I mostly disagree on the concept you suggesting. Lets say tool has imbalance 1oz on one side. in other words you can add 1oz and have it balanced. Tool itself. But lets say you do not do it and keep it unbalanced. It is still not that bad. Because torque it creates is a very minimal 1 oz over 2 or 3" (radius of the tool). The alloy wheel is 16" in diameter. Radius is 8". 1 oz over 8 inches created a torque over 3 times larger. In other words imbalance of the tool is just a fraction (rather small) of the total imbalance of the tire. But this is just a theory. I may be wrong.

[@pingpong9656]

Under $20? That’s $50 worth of steel rod you’ve got there!

[@bostig]

Ha! That's a great point, especially now! Although it doesn't have to be a solid rod like I've got there. A smaller piece of steel on a 4*4 could work for instance

[@Goldwing1500rider]

Probably MOREthan that… I paid $50 for 12 lbs steel those solid rod gonna weigh more !! 20-30 ?? Lbs??

[@TheOriginalCoda]

That a Vanagon behind you?

[@bostig]

Good eye! Yeah, that's my main business. Bostig makes zetec engine swap kits for them. The one behind me is my sunroof syncro, it's the new test mule to replace the old one. It's the testbed for bunch of things. An industrial coating vs paint or bedliner, and a hybrid conversion I've been working on. It's also got some 3D printed side mirror brackets to try some UTV mirrors. You can see the kit at bostig.com

[@TheOriginalCoda]

@@bostig Awesome. Sounds a lot of fun.

[@mustangecoboosthpp3869]

You failed to remove the old wheel weights on the tire, you can see two weights on it when you set the tire on the balancer. That is not a properly balanced tire.

[@galaxiedance3135]

Should have taken all the other weights off.. I worked in a garage, so i know that for a fact. Weights should only be in one area.

[@gerardabbatte331]

Step one. Remove all weights first.

[@bostig]

You're right, but you can also not remove them, same principle. One of them is more gooder ;)

[@motorcitymadman146]

I think its 4.5 times more accurate. Great Idea. But gonna run me and extra 70 bucks for 2 in steel bar and the ball. But it will do the job I want it to do. My wheels and tires weight almost 100 lbs each.

[@hansgray543]

This tool can only achieve static balance. Don't a car wheel need to be dynamically balanced?

[@crpth1]

In an ideal and perfect world it would be better for sure! But a really cheap digital dynamic balance machine is close to 900$/1000$. Occupy a lot of space... This basic piece of equipment can be yours for little more than 79.99$, or around that! AND it work OK! Properly used get the job done! Cheers

[@peterrivney552]

Bubble Balance I've used on my drag cars for years even my buddy uses my machine for his stock car tires it takes more time and with the tire on rim not seated you can rotate the tire to get a better balance that way as well and half the time the kids in the tire shops don't know how to use the speed machines compared to the slow process of the Bubble Balance used then since the late '60's and still works great in this day and age... But don't expect to get a balance of 4 tires done in 10 minutes ... I put the tire on the rim not seated and rotate the tire on the rim till it's pretty close to being balanced then I seat the tire then do a "Y" balance at the bottom big the "Y" is the heavy point then the top of the "Y" is where I put my weights...

[@dakinmedia5024]

You should sell this tool 🔥

[@paultech9385]

Use the Y method on the weights for more accuracy.

A large bolt that was flattened using sand paper on a piece of glass would work for the "plate." then attach to a upright kzbin.info/www/bejne/fXnYooCZrtaKoJY

[@joebushell2438]

Thats all good for hubcentric,wont work for lugcentric

[@judgestorch]

Don't do it. The ball bearing raises the center of gravity of the balancer to make it useless for most wheels (depending on the wheel offset). Just grind the aluminum lip flush on the upright rod and narrow the pointer with a grinder or file so the balancer rests on the tip of the point rather than the shoulder of the pointer (as it comes from the factory).

[@senatorjosephmccarthy2720]

Every tire is mounted to the vehicle by use of a wheel. The wheel has a rim. The wheel is not a rim. When we speak of technical processes we need to use the correct nomenclature.

LOL 😂

[@boudreau110]

... I WAS YELLING AT YOU TO REMOVE ALL OF YOUR OLD WEIGHTS FIRST BEFORE "gently" installing your tire/wheel to balance it... BUT YOU WEREN'T LISTENING !!!!!!!!!

[@theoriginalmungaman]

Your mod is severely flawed! As a person who designs and builds prototype machines for a living, I tried your mod. I took it a step further having a multi million dollar machine shop at my disposal. I machined a new shaft to go in the original base with a wide perfectly flat and polished surface for the ball bearing. The problem is if the surface the ball sets on isnt perfectly level the balancer will not repeat. If you counter bore the part that the pin goes into with a 3/16 drill without contacting where the pin seats and the sharpen the angle of the pin and polish it the balancer works perfect and repeats every time.

[@bostig]

We tried sharpening the pin, but the metal was so soft it would mash every time it was used! But the angle thing is a great point, the shaft surface should be as level as possible, most carpenters levels can keep under .3 degrees, so use of one on the shaft in two directions could help ensure it. However the repeatability problem hasn't been an issue. I wonder how your setup or use was different, do you have video of your testing?

[@johnbaptist7476]

Hello gutter🐸😂😘 🐕 ❤🤍💚🦁

[@DonziGT230]

Fail. Step 1 was ignored- Remove the present weights. In this case it would have reduced the imbalance, and whoever balanced it last was an idiot because he put them almost directly across from each other. When using one of these balancers, whether modified or not, you should re-check the balance by lifting and rotating the wheel 180, then setting it back on.

[@jacobalexander9713]

Should have taken the other weights off first

[@jamesakiba6336]

Yeah normally that's the right way, but in this case I knocked then off wheeling a while ago and was just getting to putting them back on. So the other weights would have likely gone back on as well. But good advice.

[@jacobalexander9713]

@@jamesakiba6336 if you pay attention to where the other weight was it could have moved towards where the new weight was added and you would have had less weight needed to make it balanced. Counter balancing only adds unnecessary weight. If there are weights in multiple spots on the wheel then it wasn't balanced properly. Yes it may be balanced but not properly

[@jamesakiba6336]

@@jacobalexander9713 yeah good point, I was looking for rule of thumb on how much weight is too much also... Seems like it doesn't really matter unless you're into double digit ounces lol, but then again, less is always theoretically better

[@jacobalexander9713]

When it gets to 10 Oz that is typically the most you would want and at that point you would dismount and rotate the tire some to try to reduce the weight required. I wasn't trying to be an a** with my comments just trying to be helpful

[@jamesakiba6336]

@@jacobalexander9713 no, I didn't take it that way at all!

[@getprobed838]

Maybe a thinner pipe sticking up and 2 ball bearings...one sitting on the pipe and glue one inside the top piece...so both ball bearings touch each other.
