Often just trying to figure out how they managed to screw pieces up like this is 1/ 4 the job in hand. How and why are constant nagging questions gnawing away at yer noggin eh.
I found out about this channel late last year; I'm not even a machinist nor a mechanic, just a curious guy, and I've been watching all of the vids in amazement. Seeing a master of his craft at work is always satisfying. The format of the vids is also great. It's almost like an actual course. Keep it up man.
The true definition of a craftsman one at a time , verses assembly line make as many as you can at once. This is what sets you apart from others. Your attention to quality .
its amazing watching Kurtis through multiple process repetitive jobs. Its like he becomes part of the machine itslef. great work, great video and editing. Cheers from Giddings ,Texas Ya'll
I can't help but wonder how many people are inspired to think of this line of work after watching these video's. Glad you make them. Interesting viewing.
Really enjoy your videos, takes me back to my apprenticeship in the 1970's when I worked for a mining engineering company in Yorkshire England. Would love to go back to that sort of work but only 2 years left before retiring.
Great video! Working with liquid nitrogen is something I'm very familiar with. I'm a retired Master Craftsman for a corporate jet manufacturer of 42 years. Part of my job involved was making and installing freeze plugs. Most of my job was pretty easy because Engineering would specify the diameter of the plug, but they only gave me a .0002" tolerance. Making plugs on a machine that only had .001" tolerance was a challenge to say the least, and I have made hundreds of them over the years. The small ones in the range of 3/16" was a real a** kicker. What was fun was taking the left over liquid nitrogen, usually about a cup full, I would pour on the concrete with a little toss and it would roll across the floor for a good 30 or 35 ft. Very strange looking the way it did that.
I’ve had a similar job this week broken half shaft on the difflock side very difficult job , stud it on end put a crow bar in the opposite end turned the pinion and the bits dropped out more good luck than management, I’m changing the pups name from bob to poo he likes dropping sausages right next to where your working or where your going to crawl under a machine you’ve just got to love the little fella ,, have a nice weekend guys
You just exposed the best kept secret to removing stuck bearings and bushings, I love that trick. We used pieces of paper towel soaked with bearing grease, and a wooden dowel.
Hi Kurtis, Really appreciate your attitude to quality control in everything you do. Cheers also to your camera lady and safety officer who both work hard on producing your videos. Cheers Keith
Wow, Kurtis, it seems like every video you're reading my mind as I watch regarding questions. You again popped into the video and answered them...amazing. :-)
Kurtis, that machine the hydropter, is a work of art. It’s astounding and endlessly fascinating. How it works, the precision of which it’s capable of working to, and all this entirely mechanically, for the last 70 years !! it’s incredible. I can’t wait for you to do some work on it and with it. I’m gonna be straight up with you though, I don’t think Homeless is going to be up for mastering this one just yet. I would keep him working on the lathe for a little while longer. 🥰😍❤️
I've done that! Only once on my own, though. A mate of mine (probably the best engineer I've ever worked with) showed me how to 'pop' bushes out of blind holes, by filling it with grease and then just tapping it with a drift. Some years later, I needed to get a worn phos/bronze bush out of a flywheel. The mates I had with me were all talking about butchery, until I had the opportunity to say; "Stand back, watch this." And 'bingo', out it popped. (They all said I was a smart arse!) Engineering is all about making that job look easy, but as Jack Nicklaus once said; "The more you practice, the luckier you get." You must practice a lot. Well done Kurtis and Karen.
Karen that must have been a nightmare to edit …… you did a great job. I was expecting more cockups putting in the inserts. I would definitely have fumbled a few more. I tried freezing bearings for my ATV and found it quite tricky to time it right to get them in. Ended up using a bearing press.
In my whole life i was producing virtual stuff, software you cannot touch, often cannot even see. I love to see someone producing real stuff, things that look good, have a good touch, are functional and you guys do an amazing job in showing that. My eye color? Steel blue!
In each video I discover an artist in what he does, like so many people, I spend my entire working life behind a desk, which makes me useless to develop certain activities. I see this lathe work as a therapy that some people with the talent that this requires,,, are lucky enough to do, because it evades you from everything that surrounds you and all your attention is focused on each project that you create from a piece of metal Thank you for sharing your profession with those who wait and watch your videos every Friday. Greetings from Argentina
It is a pleasure to watch a real professional do their job well. I work at a desk, I’m a lawyer, and dont know much about precision machining, what i do know youve explained to me. Keep up the good work, you are a a pleasure to watch.
Kurtis, I guess we all would like you to request your costumers for a few pictures of the finished jobs once they assemble them, if they agree... In case it couldn't get ready for the Friday's upload, may be could be added on an edition on the next week. As a suggestion/petition for future projects, if possible. On this job in particular, would have been so interesting to see it fully assembled with the gears and everything. Like always, congratulations and be proud of your jobs and videos, both of you, Karen.
You answered the question that I was wondering about in this video, regarding the reasons why you didn't make more than one bushing at a time. The reasons behind the answer you gave can be diluted down into many single words. The immediate one that springs to mind for me is professionalism.
@@CuttingEdgeEngineering My brain is dead after a fairly intense week myself, so, could you explain what adjustment to the ID of the bush [or rod OD, because the bush was solid reemed] was made, if any, to keep the fit to the rod spot on, and if there was none required, that should tell you you were right, the bushes were supposed to be an interference fit to bring the fit to rod back to what it should be too - nice and slippery with not a lot of play. Must have been a sloppy box with all that movement I'm thinking! Also what affect will operating temps have on the shrink fit - would it be none because the temps are the same in each piece of material, or is it not quite that simple?
@@paulmeersa7162 similar metals expand at similar rates. but yes that can be a issue although as they are covered in oil the heating would be fairly even while in use
Hi Kurtis I have been watching your channel for some time now and enjoy it very much. I have to thank you for not adding "music" to video's . Like hearing the natural sounds of the machinery, and your bloopers at the end. Thanks
As always, when you removed the bushing and I think, "What the heck did he just do? How does that work?" Then you explain exactly what is going on. You're always one step ahead.
now the statement of dont make more just to lose time tryin to save time make PERFECT sense ... of course i used to have to make a lot of valves an ship them out sooo understanding from a production standpoint
They are for the anti reaction pins to hold the clutch discs in place . That is a std repair to re bush them as they take a hammering . Have not rebuilt one of those transmissions in a few years now thank god , averything is bloody heavy !
I have a saying up here in GardenHill, Ontario, Canada...... One at a time is good fishin'.... Your comments regarding doing one bushing at a time makes perfect sense! Well done!
You made it look so easy, but it must've been hard work machining all 18 bushings. And then you had to install them quickly before they thaw. I'm sure I was watching magic.
I work on aircraft with tons of freeze-fit brass bushes in basically every larger fastener hole. A trick I have for dealing with small bushes is to use a normal vacuum insulated coffee mug as the nitrogen receptacle. They don't take much liquid to fill and are remarkably good at keeping your nitrogen in there for a very long time without it vaporizing. Plus they are much harder to lose small parts in among all the fog. Love the video!
Small world I grew up vary close and still live close to the folks that sent you the gifts from Maine. Another great video 👍 Also our grandson that’s in the 5th grade stayed with us last weekend, he was watching something on his IPad and I asked what he was watching and he was watching You! 😎
I love the way you read everyone's mind and know the questions we want to ask, like why did you make them one at a time. You gave a really good answer, in a way we can all understand. Can't wait for the next video.
Nice bit of high precision, good to see the hydraulic bush/bearing removal technique. Some use the cheese off a Cheese Burger I've heard? Great tip on fine surface turning 👍 👌 Great work both, top notch photography 👌. Thanks for sharing.
Kurtis and Chris (letsdig-18) are two of a kind; when doing work for other people, near enough is not good enough. No corner-cutting, no cheap skate materials because only the best is good enough, which discerning customers understand and appreciate that they are (presumably) paying a little more for a job that will last.
I once had to got to a Royal Engineers vehicle workshop in Woolwich, where I was fixing office equipment, to get some grease to pump out a bearing in a large Photocopier, and was surprised when the guys in the shop did not seem too know what I was doing. Used same technique for a Land Rover series 1 input shaft bush many moons ago. Think I peaked then....
Holy cow, that piston trick with the bushing was incredible. I would have never thought of something like that! Just another reason I love these videos.
clutch pilot bushings/bearings are generally removed the same way, pretty much any blind bush/bearing... slather some grease in there and giver a smack. sometimes the bearings are a bit troublesome due to the space for the grease to evacuate.
i've seen it done to free a seized piston in a large stationary engine. the owner removed the head made a cover plate to suit tapped it for a grease nipple filled the bore with grease by hand before bolting the plate on and pushed it free with grease pressure from a normal grease gun most of them generate around 10,000 psi so that's a lot of force. he had soaked it with penetrating oil first.
Excellent job Kurtis. About to roll in the floor laughing at the bloopers 😂😂😂😂. Wonder how long the boot will last?? The stickers are funny. Karen better wear the pink hat. Y'all take care and have a blessed day and I'll see you on your next video.
When you ran down the set of procedures to be preformed I was surprised I knew what you were talking about, great videos, great explanations. I’m learning so much, thanks.
My dad showed me that trick of removing a bushing bearing on the flywheel of his car when I was helping him change out the clutch assembly (on a standard transmission for those of you that are too young to know what that is). I'm 75 years old and learned how to drive on a standard.
Gday Kurtis and Karen, definitely something a little different and a bit of a production run, I’ve been giving them TNGG inserts a go here and I really impressed with the results, nice surface finish and able to take very light cuts, I believe they have a type of ceramic coating, i interested to see how this repair stands up after a couple of thousand hours, awesome job as always mate, have a great weekend, cheers
A job well done my friend. The effort you make in doing a job right is second to none. I'm a retired automotive tech and seen many, many persons that didn't care how they did a job, they worked for one reason only, a paycheck, I worked for two reasons, I needed the money and I needed the customers respect, so, I did it correct and felt good about the pay I received. Keep up the fantastic work and videos.
would you even save that much time doing them 3 up? you still have to take off the same material, so you would only save on the tool changes. as I like to say to people, Do you want it done fast or done right?
I had a shituation where bushings like these were walking out and the manufacturer was "eh, it's within standards" ... long angry discussion short, i'm like: "what standards? Yours, Bernard London's standards? What about my pocketses, Precious?" So the solution my friend and i came up with was to braze the OG holes shut. Placed the plate, complete with the engine on another friend's massive mill, and drilled new bushing holes, and then threaded the two parts. We used the same material the manufacturer used to make a threaded rod which was inserted into the whole deal, and bored to spec. Last op was to take it all apart, split the bushings between engine and plate and loctite them in place with vengeance. Now, when you pull the pins out for cleanup, they all pop, loudly. Chef's kiss. This has reduced our discussions with the manufacturer to zero, from where previously the setup, which involved a lot of torque (a pump from a certain "reputable" brand) would fail every once in a while depending on mixture, work time per pumping etc. IMO, manufacturers do this kind of things on purpose. My friend and i consulted several people before doing this, it's not a cheap piece of equipment, i'm basically above hobby machinist, he's more experienced but not an engineer. Everyone basically mirrored our original thoughts, even improved upon them (we initially didn't think about threading the bushing in place). Best part about this, the pump was in inspection with the manufacturer twice now, and none of their technicians noticed what we did or if they did, they kept quiet about it. Somewhere, some place, there's a bean counter that ate it, and that alone made the whole affair just that much better.
I've followed you from the truck strut top cap repair vid and then went back watched every one and have watched every Friday since...you guys have come a long way and yet you haven't changed the format.... youve just keep doing what you're doing and polished it a bit...well done to you both
Always a reason to look forward to Friday, even for us retired folk. My neighbor works at the local dealer for Gühring. Their reamers are the gold standard. I swear my blood pressure rose every time you pulled a bushing out of the LN2 and inserted it into the bore. What a relief when they all went in so smoothly (aside from the one in the offtake that you spared us!). Thanks for a very entertaining and enlightening video.
Kurtis, please don't wack on pins with your hands, you risk and will have lots of hand issues...take it from an old fart......use a BFH......big friendly hammer

Often just trying to figure out how they managed to screw pieces up like this is 1/ 4 the job in hand. How and why are constant nagging questions gnawing away at yer noggin eh.
Thankfully it’s my Friday morning fix again. It’s great to see some engineering during Homey’s video. Have a great day everyone.
that Kurtis guy still can't get his lines right, Homey never makes a mistake 😏😂
Staffie’s never make mistakes, they only have inattentive owners that misinterpret what they’re up to. 😂
I found out about this channel late last year; I'm not even a machinist nor a mechanic, just a curious guy, and I've been watching all of the vids in amazement. Seeing a master of his craft at work is always satisfying. The format of the vids is also great. It's almost like an actual course. Keep it up man.
The true definition of a craftsman one at a time , verses assembly line make as many as you can at once. This is what sets you apart from others. Your attention to quality .
its amazing watching Kurtis through multiple process repetitive jobs. Its like he becomes part of the machine itslef. great work, great video and editing. Cheers from Giddings ,Texas Ya'll
I can't help but wonder how many people are inspired to think of this line of work after watching these video's. Glad you make them. Interesting viewing.
Really enjoy your videos, takes me back to my apprenticeship in the 1970's when I worked for a mining engineering company in Yorkshire England. Would love to go back to that sort of work but only 2 years left before retiring.
Love watching your videos
this channel has all the makings to be HUGE, a cute dog, BIG chips, great people, and quality content. cant wait to see where you guys take it.
Great video! Working with liquid nitrogen is something I'm very familiar with. I'm a retired Master Craftsman for a corporate jet manufacturer of 42 years. Part of my job involved was making and installing freeze plugs. Most of my job was pretty easy because Engineering would specify the diameter of the plug, but they only gave me a .0002" tolerance. Making plugs on a machine that only had .001" tolerance was a challenge to say the least, and I have made hundreds of them over the years. The small ones in the range of 3/16" was a real a** kicker. What was fun was taking the left over liquid nitrogen, usually about a cup full, I would pour on the concrete with a little toss and it would roll across the floor for a good 30 or 35 ft. Very strange looking the way it did that.
I’ve had a similar job this week broken half shaft on the difflock side very difficult job , stud it on end put a crow bar in the opposite end turned the pinion and the bits dropped out more good luck than management, I’m changing the pups name from bob to poo he likes dropping sausages right next to where your working or where your going to crawl under a machine you’ve just got to love the little fella ,, have a nice weekend guys
I like it when you describe what you doing and what tools your using and why. Keep up the excellent videos.🇿🇦
Great feedback thanks mate
You just exposed the best kept secret to removing stuck bearings and bushings, I love that trick. We used pieces of paper towel soaked with bearing grease, and a wooden dowel.
Nothing like giving a tidy bush a good reaming 😉👍
giggity
Hi Kurtis, Really appreciate your attitude to quality control in everything you do. Cheers also to your camera lady and safety officer who both work hard on producing your videos. Cheers Keith
I like 4140 because it’s such a great all around steel. Perfect for this application.
Agreed!
I work with 4140 a lot. With proper tooling,feeds and speeds, it's a joy
Wow, Kurtis, it seems like every video you're reading my mind as I watch regarding questions. You again popped into the video and answered them...amazing. :-)
hey mate we think it might be from reading most of the comments we get a sense of what questions might get asked
Kurtis, that machine the hydropter, is a work of art. It’s astounding and endlessly fascinating. How it works, the precision of which it’s capable of working to, and all this entirely mechanically, for the last 70 years !! it’s incredible. I can’t wait for you to do some work on it and with it. I’m gonna be straight up with you though, I don’t think Homeless is going to be up for mastering this one just yet. I would keep him working on the lathe for a little while longer. 🥰😍❤️
Yeah Big nuts hasn't been showing much promise on the machinery lately, think he will have to stick to his safety officer job 😂👍
"hydropter"?? Did I miss something?
@@bobengelhardt856 -- A couple videos back.
I've done that! Only once on my own, though. A mate of mine (probably the best engineer I've ever worked with) showed me how to 'pop' bushes out of blind holes, by filling it with grease and then just tapping it with a drift. Some years later, I needed to get a worn phos/bronze bush out of a flywheel. The mates I had with me were all talking about butchery, until I had the opportunity to say; "Stand back, watch this." And 'bingo', out it popped. (They all said I was a smart arse!)
Engineering is all about making that job look easy, but as Jack Nicklaus once said; "The more you practice, the luckier you get." You must practice a lot. Well done Kurtis and Karen.
Karen that must have been a nightmare to edit …… you did a great job. I was expecting more cockups putting in the inserts. I would definitely have fumbled a few more. I tried freezing bearings for my ATV and found it quite tricky to time it right to get them in. Ended up using a bearing press.
Thanks Peter the repetition was not fun to edit 🤣
She is a very talented videographer! Thanks, Karen!
In my whole life i was producing virtual stuff, software you cannot touch, often cannot even see.
I love to see someone producing real stuff, things that look good, have a good touch, are functional and you guys do an amazing job in showing that.
My eye color? Steel blue!
Such a small OD really crank that spindle speed up to get good SBM (surface bananas/min) on your feeds. Good looking cuts ao far
In each video I discover an artist in what he does, like so many people, I spend my entire working life behind a desk, which makes me useless to develop certain activities. I see this lathe work as a therapy that some people with the talent that this requires,,, are lucky enough to do, because it evades you from everything that surrounds you and all your attention is focused on each project that you create from a piece of metal
Thank you for sharing your profession with those who wait and watch your videos every Friday.
Greetings from Argentina
Yes, the weeks complete & thanks for your work putting together my Fri-Yay nights entertainment. Just bloody EXCELLENT!
Glad you enjoyed it
It is a pleasure to watch a real professional do their job well. I work at a desk, I’m a lawyer, and dont know much about precision machining, what i do know youve explained to me. Keep up the good work, you are a a pleasure to watch.
the sound when they slide in 😍 I loved these kind of jobs when I was a mechanic 20 something years ago :D
Kurtis, I guess we all would like you to request your costumers for a few pictures of the finished jobs once they assemble them, if they agree...
In case it couldn't get ready for the Friday's upload, may be could be added on an edition on the next week. As a suggestion/petition for future projects, if possible.
On this job in particular, would have been so interesting to see it fully assembled with the gears and everything.
Like always, congratulations and be proud of your jobs and videos, both of you, Karen.
hey mate that's a great suggestion will see what we can organise for some future videos 😎👊
Nice work Kurtis, and I like the "bullet proof" quality control. Very interesting , enjoyed!
You answered the question that I was wondering about in this video, regarding the reasons why you didn't make more than one bushing at a time. The reasons behind the answer you gave can be diluted down into many single words. The immediate one that springs to mind for me is professionalism.
Nice to see the chuck key have its own spot! And I like the way you did the test for the shrinkage on the bushes. :):)
cheers mate glad you liked that
@@CuttingEdgeEngineering My brain is dead after a fairly intense week myself, so, could you explain what adjustment to the ID of the bush [or rod OD, because the bush was solid reemed] was made, if any, to keep the fit to the rod spot on, and if there was none required, that should tell you you were right, the bushes were supposed to be an interference fit to bring the fit to rod back to what it should be too - nice and slippery with not a lot of play. Must have been a sloppy box with all that movement I'm thinking!
Also what affect will operating temps have on the shrink fit - would it be none because the temps are the same in each piece of material, or is it not quite that simple?
@@paulmeersa7162 similar metals expand at similar rates. but yes that can be a issue although as they are covered in oil the heating would be fairly even while in use
Hi Kurtis I have been watching your channel for some time now and enjoy it very much. I have to thank you for not adding "music" to video's . Like hearing the natural sounds of the machinery, and your bloopers at the end. Thanks
hey mate thanks for supporting the videos and the great feedback we appreciate it
As always, when you removed the bushing and I think, "What the heck did he just do? How does that work?" Then you explain exactly what is going on. You're always one step ahead.
A trick as old as the hills my friend.
Neat trick. Hydraulic jack out only works on a bushing in a blind hole.
I like how your intro shows an overlay of how the parts are used.
23:52 I was watching this in bed and half asleep and this scared the shit out of me lol
I am so sorry about that was not aware and are editing it out now 😬😬
now the statement of dont make more just to lose time tryin to save time make PERFECT sense ... of course i used to have to make a lot of valves an ship them out sooo understanding from a production standpoint
They are for the anti reaction pins to hold the clutch discs in place . That is a std repair to re bush them as they take a hammering .
Have not rebuilt one of those transmissions in a few years now thank god , averything is bloody heavy !
I have a saying up here in GardenHill, Ontario, Canada...... One at a time is good fishin'.... Your comments regarding doing one bushing at a time makes perfect sense! Well done!
You made it look so easy, but it must've been hard work machining all 18 bushings. And then you had to install them quickly before they thaw. I'm sure I was watching magic.
I work on aircraft with tons of freeze-fit brass bushes in basically every larger fastener hole. A trick I have for dealing with small bushes is to use a normal vacuum insulated coffee mug as the nitrogen receptacle. They don't take much liquid to fill and are remarkably good at keeping your nitrogen in there for a very long time without it vaporizing. Plus they are much harder to lose small parts in among all the fog. Love the video!
G'day Karen, Kurtis and Homey great video as always and cool job to watch. Have a great weekend you three 🍻🥂
Cheers mate bring on the weekend that's for sure!
Small world I grew up vary close and still live close to the folks that sent you the gifts from Maine. Another great video 👍
Also our grandson that’s in the 5th grade stayed with us last weekend, he was watching something on his IPad and I asked what he was watching and he was watching You! 😎
Finally understood this fix, damn I need a beer.
I know your client was super happy with the precision workmanship!
Now you have covered most sections of the Cat haul trucks. Next you will be rebuilding differentials?
Great video,
jack in Glendale (AZ) USA
I love the way you read everyone's mind and know the questions we want to ask, like why did you make them one at a time. You gave a really good answer, in a way we can all understand. Can't wait for the next video.
Nice bit of high precision, good to see the hydraulic bush/bearing removal technique. Some use the cheese off a Cheese Burger I've heard?
Great tip on fine surface turning 👍 👌
Great work both, top notch photography 👌.
Thanks for sharing.
Thanks John have a good weekend mate
Kurtis and Chris (letsdig-18) are two of a kind; when doing work for other people, near enough is not good enough. No corner-cutting, no cheap skate materials because only the best is good enough, which discerning customers understand and appreciate that they are (presumably) paying a little more for a job that will last.
I once had to got to a Royal Engineers vehicle workshop in Woolwich, where I was fixing office equipment, to get some grease to pump out a bearing in a large Photocopier, and was surprised when the guys in the shop did not seem too know what I was doing. Used same technique for a Land Rover series 1 input shaft bush many moons ago. Think I peaked then....
It's similar kind of trick to shoving cotton rope down a spark plug hole, so you can seize the piston and undo the main crank bolt.
@@johncoops6897 Great one. Learned that very early on also. Lots of those tips and tricks seem to have gotten lost over time.
At least you peaked.
Holy cow, that piston trick with the bushing was incredible. I would have never thought of something like that! Just another reason I love these videos.
clutch pilot bushings/bearings are generally removed the same way, pretty much any blind bush/bearing... slather some grease in there and giver a smack. sometimes the bearings are a bit troublesome due to the space for the grease to evacuate.
i've seen it done to free a seized piston in a large stationary engine. the owner removed the head made a cover plate to suit tapped it for a grease nipple filled the bore with grease by hand before bolting the plate on and pushed it free with grease pressure from a normal grease gun most of them generate around 10,000 psi so that's a lot of force.
he had soaked it with penetrating oil first.
Excellent job Kurtis. About to roll in the floor laughing at the bloopers 😂😂😂😂. Wonder how long the boot will last?? The stickers are funny. Karen better wear the pink hat. Y'all take care and have a blessed day and I'll see you on your next video.
Hey mate thanks for watching, some great gifts from Jamie at Whistle Pig Farm!
When you ran down the set of procedures to be preformed I was surprised I knew what you were talking about, great videos, great explanations. I’m learning so much, thanks.
I'm a civil engineer but I also take interest in mechanical engineering 😋
glad you enjoy it!
My dad showed me that trick of removing a bushing bearing on the flywheel of his car when I was helping him change out the clutch assembly (on a standard transmission for those of you that are too young to know what that is). I'm 75 years old and learned how to drive on a standard.
Gday Kurtis and Karen, definitely something a little different and a bit of a production run, I’ve been giving them TNGG inserts a go here and I really impressed with the results, nice surface finish and able to take very light cuts, I believe they have a type of ceramic coating, i interested to see how this repair stands up after a couple of thousand hours, awesome job as always mate, have a great weekend, cheers
Hey mate, seeing the nice parts you've been machining up on instagram looks like all the inserts are working well 😎👊
A job well done my friend. The effort you make in doing a job right is second to none. I'm a retired automotive tech and seen many, many persons that didn't care how they did a job, they worked for one reason only, a paycheck, I worked for two reasons, I needed the money and I needed the customers respect, so, I did it correct and felt good about the pay I received. Keep up the fantastic work and videos.
When you make a freeze fit like that does that affect the ID of the bushing and if it does by how much?
I really enjoy your videos 👍
It does.. And by about the same as crush put on the od
@@brettwalkom948 thanks for the response
Didn’t think it true before i posted the stupid question
@@mrdriver511 not stupid at all.. It's definitely something you have to take into account otherwise the pin won't go through the hole afterwards
The original Bean boot! Made by LL Bean in Freeport, Maine. Cheers and happy Friday!
would you even save that much time doing them 3 up? you still have to take off the same material, so you would only save on the tool changes.
as I like to say to people, Do you want it done fast or done right?
nah would not save much time at all, really not worth it especially if you damage a part while doing that
Thanks for the "pink-basecap-outtake"
What a Beauty he is 😅
Nice Job!!! Here i mean the bushings!
Every time, someone say liquid nitrogen, 'Liquahid nitro-hagen' comes to my mind.. 😂
"It just go moosh"
I had a shituation where bushings like these were walking out and the manufacturer was "eh, it's within standards" ... long angry discussion short, i'm like: "what standards? Yours, Bernard London's standards? What about my pocketses, Precious?"
So the solution my friend and i came up with was to braze the OG holes shut. Placed the plate, complete with the engine on another friend's massive mill, and drilled new bushing holes, and then threaded the two parts. We used the same material the manufacturer used to make a threaded rod which was inserted into the whole deal, and bored to spec. Last op was to take it all apart, split the bushings between engine and plate and loctite them in place with vengeance. Now, when you pull the pins out for cleanup, they all pop, loudly. Chef's kiss.
This has reduced our discussions with the manufacturer to zero, from where previously the setup, which involved a lot of torque (a pump from a certain "reputable" brand) would fail every once in a while depending on mixture, work time per pumping etc.
IMO, manufacturers do this kind of things on purpose. My friend and i consulted several people before doing this, it's not a cheap piece of equipment, i'm basically above hobby machinist, he's more experienced but not an engineer. Everyone basically mirrored our original thoughts, even improved upon them (we initially didn't think about threading the bushing in place). Best part about this, the pump was in inspection with the manufacturer twice now, and none of their technicians noticed what we did or if they did, they kept quiet about it.
Somewhere, some place, there's a bean counter that ate it, and that alone made the whole affair just that much better.
Very interesting and great explanation..and karens getting good with the editing...give big nuts a chest slap for me
Cheers Jason, we both trying to improve on each video with what we do so thanks for watching. 😎👍
I've followed you from the truck strut top cap repair vid and then went back watched every one and have watched every Friday since...you guys have come a long way and yet you haven't changed the format.... youve just keep doing what you're doing and polished it a bit...well done to you both
Always a reason to look forward to Friday, even for us retired folk. My neighbor works at the local dealer for Gühring. Their reamers are the gold standard. I swear my blood pressure rose every time you pulled a bushing out of the LN2 and inserted it into the bore. What a relief when they all went in so smoothly (aside from the one in the offtake that you spared us!). Thanks for a very entertaining and enlightening video.
Kurtis, please don't wack on pins with your hands, you risk and will have lots of hand issues...take it from an old fart......use a BFH......big friendly hammer
hey mate thanks for saying so, easy to take my "youth" for granted
@@CuttingEdgeEngineering we all did that at one point.....hands are the most important tool in the shop.....and eyes......
Scrolled down to post this, I second the motion. Hearing loss and joint aches are not worth skipping the safety gear.
The tried & tested method you use is the right way for you so nobody has the right to start challenging that, keep on the good work you Two 👍
respect to that mate 😎👊
Even Curtis's bloopers are more coherent than Joe Biden's rambling much easier to understand!
You mean Trump’s
Kurtis, sir, all yours work with metal inspired me so hard! Your spirit shines brightly, thx!
Wow, thank you!
Thank you team for sharing. Those little bushings would twist in the hole and change the pressures. That shrink fit is a miracle
Just watched this again, with headphones. The editing and sound are excellent.
Thank you!
@@CuttingEdgeEngineering You are very welcome. I appreciate both the engineering and the production quality of your videos. There is a lot of work and skill needed to bring all this together.
When watching your videos I am always amazed at how proficient and knowledgeable you are on your profession .
Thank you! Cheers!
Enjoying your content a lot, takes me back to my time as an engineer before I ran away to join the railway. I spied an old Delapena VHM in the background, maybe from the 60s or 70s? I served my time with them in the 80’s and went into their design office for 10 years working on everything from machine design to tooling for electro-magnetic rail guns!
Isn't editing just the best CURTIS you are human I'm a fitter /MACHINIST by trade and I was thinking this guy is the Yoda of machine SHOPS never seen any tradie so chilled until the blooper reel ,love it mate keep it coming
Cheers Kym
Adelaide
That piston-bushing trick is brilliant! Love how i learn little tips and tricks here. I'm not even a machinist (yet)
Great video as always. Loved how you explained why you only made one bushing at a time. I’m sure several of us were wondering why you didn’t make multiple and it makes perfect sense. Thanks for sharing!
all good mate, we like to try and pre-empt what questions viewers might be thinking
Reaming holes is always so satisfying.
Just accidentally come across ur TH-cam page. It only took a couple of ur videos and I'm hooked on ur page. Keep up the amazing work
