Shimano Hollowtech II Threaded External Bottom Bracket Bearing Replacement
Procedure describes installing aftermarket bearings in OEM Shimano "DO NOT DISASSEMBLE" external bottom bracket bearing cups.
It was a fun project and I couldn't find any thorough guides for this replacement/upgrade. Hope this helps. Any questions, leave a comment. Thanks for watching.

Spin Bike Generator

Made a generator out out of a spin bike and an automotive alternator: One thing I forgot to specify in the video was the direction the alternator is supposed to spin. Please note per seen in video.

Stringing a racquet, set to the Benny Hill theme. Actually, Ignore the "16x" part in the description. This video is real time.

So I decided to make a how-to video about racquet stringing. It's kind of long, but I wanted to be really thorough for people who have never strung a racquet before. Hope this helps! Also, sorry about the end being blurry... Forgot to change my camera from manual focus to auto focus :(
Thanks for this video, suprising how scarce the hollow tech videos are compared to BB30
ohhh maaan. i just ordered the same bearing puller tool from amazon together with the new bearings. i thought i could pull it off with it. it was the washer that didnt fit? if so, its easier to get one that fit and file square to 22mm
Hi Andy. Something remains unclear in my mind. The Mountain BB uses a wider plastic sleeve to provide additional protection against mud and other contaminants. Which is supposedly not necessary with the Road BB allowing for a wider standard bearing (7mm thick). So I don't understand what drives Shimano for the design, because if we consider that the road and MTB spindles have the same length, why not use the length that allows the mounting of the 6805 standard bearing in both cases but by changing the width of the plastic dust cap for a perfect fit with the crankset ? Where am I going wrong ? 😤
I have exactly this on my road bike. MTB BB minus the dust sleeve and commonly available 7mm wide bearings
👍
Please sar bearing number
Hi
Bassball style cap makes wearing a hood up a bit more bearable, do like a poncho. I used to use a clear bin liner with taped up arm holes back along just cos it went right over my backpak.
Algorithm comment😂
Great, great, great idea but the alternator is really a horrible choice. I want to build mine using a 250W hoverboard motor. I spin it with my bare hands so easily and it puts out a lot of power. Cheers! Thanks for the video!
Great video bud
My extension #1 of your idea is for your bicycle to turn a good-sized flywheel using a connection with gearing of multiple sprockets, like a 10-speed bicycle. The flywheel is connected by suitable gearing to some number of DC generators, which feed power to the batteries that power your home's devices. The flywheel's inertia can continue to spin your generators when you stop pedaling and allows you to maintain the flywheel's rpm with less pedaling effort. My extension #2 of your idea is to a) identify the power required to lift a large concrete block using an electric winch device and b) identify the size of the block that can spin generators producing your required power output per unit if time. After lifting the weight, it drops down an inclined plane during some long number of minutes. It is connected by a weight-bearing cable to a suitably geared set of DC generators to produce a given amount of power per drop/reset cycle. The generators connect to batteries that power your home's devices. (You canset up as many falling blocks as you need to generate the electricity that you want to be available over some period of time.) All of the blocks are set up outside your dwelling, of course. You pedal your bicycle only to recharge a battery to drive the winch. This kind of system is simple and avoids the complexities and fragility of wind turbine and solar power systems. I would also prefer a recumbent bicycle seat.
Great project. Thank you for sharing your experiences planning and building this. If I make something similar I'll post an update to this comment.
Can you fix the alternator in place that you have already then use another alternator to tention the belt and get more power from 2 altenators insted of 1
Thanks for sharing . Wonder how you could get multiple people to drive it . Should get more rpm .
Hi, may I know how much it's total cost, thank you.
This African older gentleman just made a bigger wheel and he could power his TV for 2 hours after only 2 minutes of peddling. You should use lto batteries and also a higher Amp alternator. BMW alternator or something.
I mean... I could power my tablet for 2 hours with 2 minutes of pedaling (probably). Battery chemistry wouldn't change anything. A different alternator doubtfully would either (maybe be 60% efficient instead of 50). Would need an expensive brushless motor and inverter drive to make this system efficient. Let's say it's 100% efficient. A Tour de France biker puts out 400 Watts. This TV uses 40-ish Watts. That means a TDF biker could pedal for 6 minutes to run this tv for 60 min... In a 100% efficient system. Still have to abide by the law of conservation of energy
Andy, you are on to something. If venture capitalists / investors take your idea and produce a complete product, you'll be rich. Something Elon Musk, his hardware (frame, electric motor/alternator, display etc) and software (app, internet of things, forum, social platform etc) engineers could take on.
Good Idea, instead I use nuclear energy to power up my house equipment, I will definitely use kinetic energy, wind power, and solar energy, if water energy, you must be near a waterfall if Steam energy you need a boiler which more energy use, so 3 choices or 3 ways to cut off my electric bill totally,
This is more of a disaster preparedness thing. Very useful during power outages. Enough to charge essential gadgets and items.
@@andyw4506 I think this is at least much "better" than to just have the resistance from the stock roll-trainer! Cool project Andy!
I don't know much about electricity, I'm queries, is it possiblle to use many alternators/generators to charge a deep cycling buttery at the same time...?

Man turn the light on it might help geeez
great video! I have the same stringer, but I have a problem when trying to mount my pure aero. the bridge of this racquet is thinner than the frame, so the throat C clamp cannot exert even pressure on the bridge to secure it. the thicker frame gets in the way. do you have any tips to get around this issue?
I personally would probably just crank the clamps down, not worry about it and string away (as long as nothing slides around). If you really wanted to fix the problem, I'd try to find some rubber (or maybe felt?) of the appropriate thickness to cut to the proper shape and place between the clamp and the throat.
Thanks for taking the time to make this video. Haven't strung a racket in decades and just bought a Gamma X2 because I started playing agin. Very helpful.
Thanks! Glad you liked it.
Great vid man, definitely the most comprehensive I've seen for the X-2. With your help I was able to do my first ever string job with little trouble.
really good stringing vid here! Have been stringing for 5 years and this is spot on. The clamps might however be on the tighter side of whats reccomended. They should also be put a bit closer to the grommet. Always place them as close to the frame as possible.
Great video! Really useful thanks
thank you
Isn't it better to tension each time you weave a cross string? I noticed that you did two rows of crosses and then tensioned. Just wondering what the reason is behind that.
ChaoSquared When you begin the cross strings, you have to thread the first two rows before you bother to tension, at least with floating clamps. The first two crosses must be tensioned simultaneously, then clamped so they hold their tension. After these two, each string should ideally be tensioned individually.
Thank you, excellent video; lots of detail and easy to follow. Can't say that about the manual!
Thanks for this video. I just ordered the Gamma X-2 and am a first time stringer so I appreciate the tutorial. Hopefully I can actually get it done because I'm tired of running to the shop every time I want to try a different string setup and paying so much to do it. Do you have any idea how to calibrate this stringer? I've heard they can be a few pounds off out of the box.
khalsted Calibration... You would have to purchase a spring scale that measures in this range. I would attach it to the racquet holding clamps, tie a piece of string to the scale, then wrap the string just like you would do to tension a string. At this point, compare the value measured on the spring scale to what the drop-weght is set to. From what I've gathered (I'm a physics guy), drop weights are incredibly accurate and precise, provided you ensure the weight is horizontal within a few degrees when you tension the string.

geepeeone Heck yeah! Excellent player's racquet, one of the best <95 square inchers I've found, especially for the price. Then they went for dirt cheap on closeout at Tennis warehouse. Stocked up
Nice job bro, lighting could have been better, but excellent instructions, now I'm going to give it a shot!
Great video man. It got me through my first stringing. Didn't have enough string first time but its finally done. Thanks :)
Im thinking about getting one of these but I hear bad things about the clamps durability. Is this true?
It is not bad lighting, it is just Rembrant like illumination. :D
great vid just bad lighting
