The time they wasted by not heating the wheel and freezing the bushing is largely compensated by the money they saved on gym membership. Hammering it in this way is not the brightest thing to do, but it's a damn good exercise.
Thanks for watching and supporting us keep attached with us 👍❤️
Heating the wheel is not going to help because of its size.
Удачи Вам парни в Вашем нелегком труде!
Thank you so much for your kind support greetings from me ❤️👍
Это не местные забивают втулку, это руские шабашники...🤣. А токарь местный, молодец !
The sleeve should have been kept in a fish freezer (-20 degrees there). It would be much easier to take her place. In the presence of liquid nitrogen (it is always available in factories) or a cylinder of carbon dioxide (carbonated water is made using such gas from such a cylinder), you can cool the part in minutes. The part is placed in a bucket, covered with rags on top and around the bucket, and a hose is inserted into the bucket, carbon dioxide is supplied from a cylinder (in extreme cases, if the part is not large, we used a carbon dioxide fire extinguisher).
Great information sir thanks for sharing your experience stay safe and healthy and stay attached with us
Se nota que no conoces el pais y sus medios...además de lo que has dicho también podrían haber calentado la rueda...que facilita mucho el trabajo...pero es lo que hay.
Looks like they don't mind the work, impressive to see to say the least
A gas torch on the flywheel and a freeze on the bush will help save a lot of eardrums

Did you see that guy in green near the end of this video using a snag grinder, without safety glasses, hot chips and flames flying everywhere, gives me goosebumps.

Для обработки деталей таких размеров обычно используются карусельные станки...но, понимаю,что тут используется то,что есть.
И очень понравился пресс,для запрессовки втулки!

I’m always intrigued seeing these men at work. Also I’m puzzled at times…
This seemed a large workshop, with a lot of heavy equipment. Was there no press available? Or a 20t or 30t hydraulic car jack? A steel beam frame is always handy to have around. The fit seemed very well made, without measuring the actual sizes, much respect for that. (And the same compliment for placing the wheel on the lathe.) As to the finishing of the bushing I could not determine what procedure was followed. This is what I would have done: after placing the wheel on the lathe and boring out, I would have also faced the hub. Only just. When placing the bushing, a depth caliper or a square can be used to ensure correct alignment. Lastly when finishing on the lathe, I would have bored out to the final diameter in best alignment at 90 degrees angle to the circumference. And a final face off, of course.
Come to think of it: a smaller jig using a bar or bolt and a loop could be improvised for placing the bushing. The car jack would be placed on the opposite site of the wheel to pull the bushing in.
Keep up the good work, gentlemen; I hope to have been of help with these comments.
Yeah off course you’ll given to us very important information thanks for sharing and appreciate you salute you👍❤️
that cost money , it takes up room , how much would it get used and not having it gives someone a job so in the end its cheaper and more people have work
@@chrisjarvis4449 good arguments!
But it would be a simple and easily rearranged tool that would be cheap in comparison to the press I somewhat expected to find in this workshop.
And an argument regarding control over quality: Hammering in such a fit has a huge risk of going wrong due to wriggling when entering the boring.
Either way, it is neither up to you or me to decide🙂.
i hear what your saying ! its just that they have lots of people and time . its like when they made the hover dam ! oh someone got killed today ! that's ok there's 1000 more outside the gate looking for a job ! but not only that but ! that's the way we have always done it ! and it gets the job done and done on the cheep !
better would be using dry ice and hot water.
Build a fire under it in the morning with a pot of beans in the center. After you eat the beans for lunch, drop the bushing in. That's how we do it in Tennessee! LOL
Thanks for watching and supporting us keep attached with us and thanks for your advice and idea
Or drop the bushing in a drum of Liquid Nitrogen. After 1 hour the bushing will fall in just like that...That's how we do it in The Netherlands.🤣

Safety is for wimps with these guys.It bothers them
gotta like the way he measures. precision at its best. also, notice the other guys "safety shoes." and their "press" is outta this world.

Takes me back to making textile machines in England in 1962-3-4. Calipers and ruler.
Really appreciate you but we have still in this position
@@mimechanics1019 Yes. Not a good way to work.
Most UK engineering businesses shut down because the bosses and bankers would not invest in new machinery to keep up with Germany and Taiwan and now China.
My dad could read a pocket scale to .005". I'm lost at anything less then 1/16 anymore. God bless Dial Calipers and Micrometers. I'd be dead without them..
@@mathewmolk2089 I'm almost 76.
Just read my vernier to the thou!
It blows my mind watching these men without personal eye protection around flying metal! Is that a luxury? 😱
There is no safety’s for labour
Back in the 70s in Australia it was rare for a machinist to wear safety glasses, in fact we there was hardly any hearing protection and those 9" grinder were destroying our hearing but still no hearing protection. I worked at place with 400 men, no women. So all in all these guys they weren't any different. But no spring calipers only fixed jaw, too many mistakes with spring calipers. You had to feel the bore until you just couldn't feel, then you had to have same feel with the micrometer. Oh the joy of my first use of telescopic bore gauges, never went back to calipers
Safety squints
And steel-toed sandals.
@@DrOps696 the safety squint was developed for arc welding 😅

Should have put it in a fridge for a couple of hours to shrink it.
Looks to be about 8 inch diameter so dropping temp by say 60 degrees would make it shrink by about 2 thou.
Sir if we fridge the bush can we press it easily?
Yes, lookup thermal coefficient of expansion for steel or cast iron. I estimate you'd get about 0.03mm of reduction in diameter if you chilled the bushing 27C below the temperature of the wheel.
Wow you’re incredible man thanks for idea great job done sir greetings from @mi mechanics
@@mimechanics1019 In freezer part of fridge where temp will be about 25F or 7 below freezing the 8 inch bush would shrink by about 2 thou.
Same goes for heating the flywheel.
Try heat it up to too hot to touch - 300F and it will expand about 2 thou.
Then the bush will drop in . Pour some water on to cool the flywheel or leave it for an hour to settle at room temperature and it will hold the bush tight.
I was doing engineering straight from school 60 years ago.
I used to make lots of precision things and always cooled them down to get the correct size.
In the assembly dept they had an oven to heat up bearings by about 200F so they just slide on the shafts.
@@mimechanics1019 You know the video of putting new bearing on shaft of crusher two weeks ago?
The man put burning rags inside the bearings until it was too hot to touch then it just slid straight onto shaft nice and easy?
That bearing probably expanded by about 2 thou so it went on easy.
When making a bush you must do the opposite: cool the bush and heat the flywheel.
Here is the formula to calculate the expansion or contraction of iron and steel.
Get calculator and multiply 0.0000065 X diameter of piece X degrees of heat or cold.
Is workshop temperature about 70F ? so the flywheel was also about 70F.
If you can get some ice cubes in bucket of water and put bush in for 15 minutes it would cool from 70 to about 34 - a 35 degree drop.
Then its diameter would shrink by 0.0000065 X 8 X 34 = 0.0017 thou.
The big bearings on the crusher shaft had inside diameter of about 8 inches? And it was heated too hot to touch so about 250-300 degreees? So 300 degrees hot minus the 70 degrees of workshop = 230 hotter.
So multiply 0.0000065 X 8 X 230 = 0.011 or 11 thou. So it slid on easy.
Great job Carry On ❤️
Thanks for supporting me brother 👍😆
Nice job setting up that big flywheel in the lathe. Loads of mass there!
Thanks for watching and sharing your thoughts with us stay attached ❤️
Blows my mind that a shop can have all those lathes and yet not one caliper or micrometer not to mention a hydronic press but they'll beat the crop out of the bush to put it in chuck it in a freezer for a few hours it should drop in but no they do it the hard way every time.
Well they probably had calipers but used them all as adjustable wrenches... Seriously there is nothing that'll these guys won't break.
Guarantee you put that old man on a bridgeport against you no cnc and he would run circles around you.
Or an engine lathe which im pretty sure that is.
It's all refurb work, only have to measure against existing parts, actual numbers aren't important.
@@FourthWayRanch Runnout during setup is incredibly important..
Very impressive. The workmen are very smart and manly in their work. An oddity is their high pitched voices. The only thing I can think is that it might have something to do with the strong vibrations of the machines which might have a gonadular effect, or, it could be as simple as their loin garrments might be drawn too tight. No matter, their work is brilliant.
Thank you so much 👍❤️
This operator IS using an external caliper to measure the outside diameter of the bush. He is also using an internal caliper to measure the inside diameter of the wheel. The amount of interference was judged by his experience. Please get your terminology correct..🥴🥴
However, they should have used anti seize on the bush id before trying to hammer the bush into the wheel.
Thanks for sharing your thoughts and experience with us 👍
Night has fallen and still they hammer the bush home.
Next time chill it in a fridge.
Yes we are hammering for 3 hours
@@mimechanics1019 Not easy to be precise with calipers.
Boss needs to buy a set of inside and outside micrometers to save all that time and effort.
Tell me something: Are there very strict laws against importing from China as over here in UK we get Chinese tools very cheap and they are very good quality.
Here is not strict law for import exports here is commonly we can buy Chinese toolset

This is a normal method. They just do it very crude...and normally an Allen bolt is used for this method. Indeed to get it out later...but when he was done grinding he doesn't immediately takes the grinder of the material and leaves a nice track....arghhh...Why???

drop the bush in liquid nitrogen and it will slide right in
Thanks for idea we appreciate you greetings from us 👍
Dry ice (frozen carbon dioxide), if available, will also get it very cold (approaching -78.5 degrees C) if you put both the dry ice and the bushing in a well-insulated box.
Why don't you use coolant on the lathe? The finish will be better and the expensive tools will last much longer ,, just why??
We are using low quality of coolant for lathe machine like reuse oil
