You should have been a teacher, Sir. I've had many rotating assemblies balanced during my 70 years, but I never knew just how entailed the service actually was. Thanks for the lesson! I have a new respect for the guys at the Speed Shops.
Man that's unrealistic I've read about tesla and frequency where he collapsed the building by using the same frequency the building was omitting explains alot Yamaha making moters and helping other car company's build there moters thought it was about design really good video changed my perspective on engine building big time thought getting good parts is all needed to go fast thank u for the video do you grind cams by chance
Thanks for the info Gerald. You've gotten so much better in such a short amount of time of filming/taking and explaining. Not that you were bad at all. Just meant your doing great. Have a blessed day brother.
Machine shop I went to for over 20 years close. It has been in business since the early 60s. Owner passed on. The crankshaft specialist had done nothing but cranks there for 39 years. I have 15 done by him as my own inventory. Not sure I will find another guy as skilled as him.
Never would have thought I would have figured out how instant center worked while watching a crank shaft getting balanced . You are the man Mr. Brand keep the content coming we're here for it 👏
Best explanation of harmonic resonances I have ever heard!!! 4 years of Mechanical Engineering no professor every explained it better than you just did...🤯🤯🤯 Love these technical video's keep up the great work!
I have always been fascinated by the great work you do. I could sit and watch and listen to you for hours. Thanks for all you have done for us dirt racers over the years.
You don't have to respond to my comments! I don't take it personally. I'm sure others feel the same way. We don't want you to get burned out doing all that! Your videos are VERY informative and it would be a shame if you stopped! I have been a machinist since the early 80s. Most everything except jet and automotive engines. Watching your videos makes me wish I had gotten myself familiar with automotive engines! Thank you for continuing to share.
I love listening to ppl talk about this type of technology and the experiences that they have used in. Thank You Sir, your videos are always very informative.
Thanks for sharing your knowledge with all of us. If you don’t share the knowledge that you have and pass it on and we don’t have anybody to go to to do this anymore the younger generations aren’t anything like this it’s nice to have somebody that you can ask questions and get good answers, and keep up the good work your videos are great
Stumbled on your channel this morning from another channel that I try to learn from but he's too hard to follow.. watching yours I understood every concept immediately! Thank you for the knowledge and keep it up, I hope you get more recognition you deserve it.
The high vibration frequency you're talking about is called a resonant frequency or a critical frequency. Everything has a resonant frequency. Changing Mass or Stiffness will change the resonant frequency. Excellent Video. Keep up the good work.
I think what a lot of people could relate to is a tire/wheel slightly out of balance, when you hit that certain speed or in this case frequency it balances out and it’s smooth sailing.
Thanks for the sharing the balance percentages and the balance info. The secondary which occurs at double the frequency are specifically referred to as a harmonic. 1st can be 50, 2nd 100, 3rd 200, 4th 400 and so on. Im enjoyin your content and look forward to the next.
Thank you. I’ve had it explained to me a couple times and left understanding it less each time. But I’ll be damned I understand it now ( at least for the most part) wow you have a special way of teaching for sure. Thanks again
Before I was born, my parents both worked for a man named John Schleper, (Schleper's speed shop) in Brookfield Wisconsin. Now Propower Motor Sports. Anyway, about 5 years ago I went with my Mom to John's 80th birthday, and had the chance to talk with him about this stuff. I have about 300 diesel engines under my belt myself, so I get it. But it was really cool to hear this stuff from someone who was part of the pioneering of this tech. He told me the hardest thing to find these days is someone that can run a manual crank grinder. Everybody runs CNC and the skill of running old school tools is fast disappearing. Today's mechanics don't really get how to do this stuff. My dad used to grind cams for him back in the days before I was born, I'm 57 now. The idea that you could just order up a cam from jeg's didn't exist. The only way you got a new cam was to make it. You didn't have tech bulletins, or spec sheets, or even an idea of what worked best. You had to try it and see. Then prove it on the track. I wish I was able to do some of this stuff over the years, but I am out of it these days. Thanks for sharing the knowledge, and pass it on to whomever you can. These are dying skills that need to be saved.
Great video Gerald, I appreciate your explanations and experience. I hope this convinces people that balancing is not a luxury but is very necessary. I have always been an advocate of balancing. And yes, every engine is different and unique acording to it's design and use. Thanks for sharing. Have a great weekend. 👍 🇺🇸👍
I would like to take the time to congratulate you on doing an amazing job. Without people like you and your knowledge, experience and passion a lot of folk would struggle to at least have the option to save a motor. Its a dying art and i really hope the baton can be passed to someone. This insight into what happens to a motor is priceless imo Your ability to explain it in a way not to confuse folk second to none. Keep the vids coming I hope Justin and Jackie had some influence on getting you to make these videos Nice job Gerald 👍
Great job Mr brand you remind me of my uncle back in the early 90s teaching me performance machining in his automotive machine shop I worked for him many years honing the skill you are going to go places on here keep up what your doing
great job have had a lot of engines done but knew about the bob weights but never knew how they arrived at the correct weight. i knew they weighed the pistons, pins, both ends of the rod. thanks for going to the trouble to explain
This was awesome... THANK YOU! I am not mechanically inclined by any stretch of the imagination. I am a retired paramedic, and what you described with crankshaft, harmonics, vibrations etc, very much reminds me of some of the finer intricacies of how the cardio vascular system functions in relation to the central nervous system and how they affect the other systems of the body. I know I know completely different worlds, but I found some of the similarities interesting. You rock Gerald.🙏💜
I am a prior F-15 Crew chief, who now does tech. Understanding hydraulics helps a lot in understanding the mechanical fluid dynamics of the cardiovascular system. It's basically a closed loop hydraulic system.
Oddly enough one of the most curious things about the world is that everything has a frequency. The human body has a frequency of 7 Hz if I remember correctly. Every element has its own frequency. Every atom is vibrating at a certain frequency. It's strange how it works, and only Mr Tesla truly understood it well enough to put it to use.
I worked on rotational equipment in the HVAC field. Mostly fan supply units and studied vibration and frequency. Had a cheap vibration meter but when used with some knowledge and experience I could find worn bearings ,pulleys and cracks in motor plates. some big equipment has vibration monitors permatley on them.
Mr Brand reminds me of the teacher in school that no matter what he was teaching he made it interesting. I found this vlog very interesting Mr. Brand. Keep them coming
Please document an entire balancing process!!! I learned this in the early 2000s, and would love a refresher course from an experienced professional. I machined a 383, out of a stock 5.7 using Eagle's "balanced rotating assembly" (boy, were they off), and switching from internally balanced, to external was a pain. (Needed mallory) Anyways, looking forward to the growth of this Channel. 👍🏻
F1 engines can turn over 20,000 rpm but is regulated to 15 and they are alot smaller displacement then the coyote engine. I think the problem they're having is from cheap manufacturers. Awesome video as always sir. Thank u
Nice video 👍 Balancing is an interesting topic. Especially when you talk balance factor. Some ford engines use 35% while others 55% wich seems a big spread. The machinist I hire doesnt think balancing of the crank is that important for a street engine. He actually turned down taking my money for it. 🤷♂️ He does weight match all the rods/pistons to less than 1gr however. Even does it on diesel tractor engines.
Awesome! Being able to see the process and the theory makes it all easier to digest and understand. Thank you so much. You really are a good teacher and I am sure this video business will get easier for you quickly.
Hmm.. There certainly is more than one way to skin a cat. Good video! Straight to the point and the explanation was solid. Definitely liking the style.
Thank you for posting the video. I love watching this kind of technical video even if I don't understand full of it. But I promise you I try my best to understand ! 🙏
I don't remember the exact story but I think Mario Andretti or someone in a penske car anyway was dominating the indy 500 and slowed to conserve the car, and dropped it out of its balanced operating zone and blew up after a few laps....
Mr. Brand, your the man. I am interested to see if you would share some more Buick v6 knowledge with the turbo Buick crowd. I would love to see a series on Buick turbo v6 tare down and rebuild with all the steps in between. Thank you for all this awesome information
![How To Balance Your Pistons And Connecting Rods [#TECHTALK]](/img/n.gif)
all the voodoo of taking parts to the machine shop is slowly being revealed on this channel and i absolutely love it!!!!! nice job Mr. Brand!
Take the engine voodoo to the doctor. Dr. Brand will put some good juju in your engine.
Same.
Now if Bill would become a fuel tech expert that would be letting all the secrets out
Does the rod ratio have any effect on the % you use? We are running really high ratios 2.0 and 1.96
You should have been a teacher, Sir. I've had many rotating assemblies balanced during my 70 years, but I never knew just how entailed the service actually was. Thanks for the lesson! I have a new respect for the guys at the Speed Shops.
I was the teacher assistant in vo-tech to the night class when i was in high school
I know right

He lost me there for a minute, but when he got to frequency in relation to RPM I started to understand again. That's pretty cool.
Thank you. That explains a lot. It's no wonder Chief goes to you.
Thanks for the info Gerald. You've gotten so much better in such a short amount of time of filming/taking and explaining. Not that you were bad at all. Just meant your doing great. Have a blessed day brother.
Man you went from crank balancing straight into suspension tuning …. We know where Chief learns all his secrets now 😂 Great video !
Thanks for putting in the effort Gerald! We all appreciate it
Thanks Gerald for the ways of balancing a crankshaft. I or I'm guessing all of us appreciate all of the information that you are giving us! Peace

Everything in your shop is very cool thanks for sharing 👍
Nice work Sir ... looking forward to more G.B. goodness!
God Bless!
😎
Nice Going Rhett !
thank you d scaglione!
Nice informative video, added bonus with the nascar stuff with reising the rpm to get out of the bad frequense area 😊👍
Stumbled on your channel this morning from another channel that I try to learn from but he's too hard to follow.. watching yours I understood every concept immediately! Thank you for the knowledge and keep it up, I hope you get more recognition you deserve it.
Thank you for sharing your knowledge. Your channel has become my favorite.
keep doing what you do best the rest will come naturally as time goes on loving the content love from the uk

Excellent info sir, thanks for taking the time to walk us through what it involves in balancing the crank.
Thank you. I’ve had it explained to me a couple times and left understanding it less each time. But I’ll be damned I understand it now ( at least for the most part) wow you have a special way of teaching for sure. Thanks again
Love learning this stuff. My dad worked 37 years as a manual machinist at Cincinnati Milicron. It all seemed like wizardry when I was younger 😂
Thank you Mr Brand for another informative video. I had no clue that the Buick v6 crank was so different.
Thank you for taking the time to teach even old guys like me. I’m working with a local machine shop on a junked Vortec 383 deal, so this is perfect.

Great Job!! A lot more goes into it than I would have thought.
Thanks for taking the time to explain this Gerald.
So, I guess when you go 51% or more, that is what's called an overbalance. I always wondered what that meant. Thanks, I learned something new.
Thank you for sharing your knowledge about engine building and machine work, lots of tips and tricks people pick up over the years.
great job have had a lot of engines done but knew about the bob weights but never knew how they arrived at the correct weight. i knew they weighed the pistons, pins, both ends of the rod. thanks for going to the trouble to explain
Good job! Talking to a camera when no one is on the other side is awkward. It gets easier the more you do it.

thank you for sharing that with us Gerald
Awesome video, Gerald. Full of great information. 👍
I used Gerald for my engine work back at when I raced. He for sure knows what he’s doing. Never had an engine failure related to his work.
Thanks! Great video Gerald, and welcome to TH-cam.
Nice video 👍

Love the grinding, never liked drilling a crank, it seems wrong that your removing excess material as your not removing it from where the issue is
Thank you for your patience telling us the best way to go about this!!
Great video. I didn’t know how much went into balancing a crank.
Awesome! Being able to see the process and the theory makes it all easier to digest and understand. Thank you so much. You really are a good teacher and I am sure this video business will get easier for you quickly.

But I promise you I try my best to understand ! 🙏
Thanks for Sharing Your Knowledge , this is the difference in making an engine live and throwing one together and wasting your money
Over my head Gerald, but VERY INTERESTING. Thanks.
Thanks for taking the time to show and teach!
Thanks for sharing! I look forward to the next video
Awesome video another good channel shout out to chief for sending me here
Yes, it's very important. Especially for longevity.
Good to hear you voice again, Gerald. Glad I found your channel. One of nicest guys I ever dealt with. I like the no holes balance 🏁
How's retirement. Hope all is going well.
@@BrandRacingEngines Retirement is all I wanted it to be ! Life is good here in NE Arkansas, grandkids seem to tolerate me. Wife, too. Take care 😎
I found this to be very fascinating. That's the first time it's been explain like that to me. Appreciate it. Thank you.
Thanks for sharing
U do good work. And u're catching on 2, this TH-cam stuff 2.
Love you channel Gerald. I used to build race engines in the 70’s and 80’s , wish I knew then what we know now.
Thanks
I don't remember the exact story but I think Mario Andretti or someone in a penske car anyway was dominating the indy 500 and slowed to conserve the car, and dropped it out of its balanced operating zone and blew up after a few laps....
Love your video Sir , balancing is so important in high rpms !
Thanks for the videos with this kinda info and keep them coming!
Good stuff. Thanks
Awesome! Thank you. Very educational!
That was great information! Keep the videos coming I really appreciate you sharing your knowledge with us!
Fantastic information. Excellent video thank you. Looking forward to more.
Another video! Nice!
Valve train reciprocating mass sends a lot of harmonics back down into the bottom en of the engine also.
Valve train tears up a lot of things people don't think.
Awesome job SIR...
Very cool that explained a lot. Know I gotta know more 🤦
Mr. Brand, your the man. I am interested to see if you would share some more Buick v6 knowledge with the turbo Buick crowd. I would love to see a series on Buick turbo v6 tare down and rebuild with all the steps in between. Thank you for all this awesome information
Have not had a Buick in the shop for over 2 years.
Thanks Gerald for allowing us into ur world ur amazing
...great video ! Love the tech explanation !...
Thanks for your time and knowledge sharing
Thank you very much, you explained it very well. You are doing a fantastic job. Keep up the gr8 work 👍.....🇦🇺
Thanks for sharing!
Thank you so much for starting your channel.
Awesome video dood.
Great video. Very informative. Thank you.
Big chief sent me.. subscribed! 👍
I ever seen this done but I have paid to have it done in my old racing days . Very cool. Thank you
Thanks, i reckon second order harmonics matter in most things.
You are awesome sir.old school rules!
Can you answer a question about an externally balanced 454 and how you can balance, the crank, and then use a regular balancer
Have to have a weighted balancer & flywheel
Cool video!!! I have done some balancing,we where less than 10 milligrams and rpm’s up 30,000.
Thanks for sharing!!!😎
Doing great bud!
