Why I Fixed This Hydraulic Trunnion The Way I Did - Trunnion Repair Follow-up
Вставка
- Опубліковано 14 тра 2024
- Every job has its challenges and are great learning experiences. In the 25 years I have been doing jobs like this, I have seen many failures of attempted repairs.
Hydraulic cylinders with trunnion mounts of this style are generally not a high pressure application, so sleaving is the absolute best option. Welding and turning down brings in its own potential problems, which I have had first hand experience fixing other shops mistakes.

It never ceases to amaze me how people think someone is doing something wrong and are not shy about telling you from far away. You do lots of things that I wonder about Josh or maybe in my mind it might not be the best practice. However what we do as repairmen and machinists is often governed by our experiences, tooling, job requirements, customer wishes etc... Besides, in my case anyway, the type of work you do is quite a bit different from what I do for the most part. Even though I too am a machinist, welder and machinery repairman, that does not give me license to sit 900 miles to your east and to say you are doing something wrong? Hell if I keep my yap shut and watch, the questions will most likely answer themselves. I am more interested in the journey how you make out in the end. Plus if I pay attention...I just might just learn something from that kid out west! what a concept eh?
You keep on keeping on brother and get those customers going again best way you know how, I have a feeling repairmen such as us are going to be in higher demand if things keep going south.
Surprisingly, I learn a lot from the comments. Sometimes I learn an alternative way to try and find it to be better. Sometimes I learn that the human race is doomed. Lol.
Came for the railroad stuff and stayed for the machining stuff.
Sadly, I can't do railroad videos anymore. Threats from the FRA of fines,using the videos as evidence. It's not worth a $5-10k fine.
NICE WAY TO SET THE RECORD STRAIGHT ON TRUNIONS
The only question I had about you sleeving the trunnion was "How many EXPERTS are going to disagree with Josh in the comments?"
Lol, lots of them.
Lots of naysayers. Josh probably remembers the old song "If it feels good, do it."
You did it the right way, not sure why you always have to explain yourself
@@powerhungrytoo I'm not. I'm just answering questions that were common in the video.
Always amazing the amount of people
Who think they know better on how to do a job you all have to remember Josh has bin doing this for a long time and knows how to to Get it done right the first time shameless plug there
I've been a welder and fabricator, and an industrial mechanic, now retired. Welding can be problematic. Some applications just aren't suitable for welding and that trunnion does seem to be one of them. I agree with your explanation. As a mechanic in a manufacturing plant, I've had to weld things that just shouldn't have been welded. I got away with it most of the time, but I was praying for the new part to arrive before it broke again. Not something I'd want to do for a customer.
Glad to hear I’m not the only one who’s been forced to weld things that shouldn’t have been welded 😅
I like this concept of doing a follow up video addressing comments and lessons learned. I wouldn't mind if you made it a regular feature of the channel.
Thanks. That is the goal.
Really enjoy your comments and videos. Fun to watch a skilled machinist at work
Thanks
I fully understand the bending over. I had back surgery and bending over is bad for me.
I feel your pain on running older machines Josh some of them are so low. I'm a fairy tall guy myself 6'5", and it sucks having to hunch over to run them. I have an old Axelson and old Bridgeport that I use at work that were so low I couldn't comfortably run them, luckily I was able to talk my boss into letting me raise the Axelson lathe up 10 inches and the Bridgeport mill up 8 inches, and now I actually enjoy running them, but it does make them my machines now as they're a little high for everyone else lol, which is just fine with me. 👍👍
Hi Josh. You’ve really started an Anchor lube revolution on UA-cam. Since you began featuring it in several videos I’ve noticed quite a few machining channels trying it out. A couple of large channels too.
I know you weren’t the first one to introduce it. It’s been around several years now, but after your recent videos there’s been a definite trend of others jumping on the bandwagon (in a good way).
Anyway, just thought I’d bring it to your attention if you haven’t noticed it already. 👍🇳🇱
If you decide to sell the Green lathe I would suggest that you create a video showing how to work around a worn out lathe to make great parts. Kind of a tips and tricks video. A lot of the hobbyist watching you probably have old worn out equipment and could use your advice. At the same time you would be demonstrating the usefulness of the lathe to the next owner.
Josh- Congratulations on 100K subscribers. That was really fast. 😃👍
No, No, You did that trunnion repair all wrong. Typically I just throw those types of repairs in my time machine and turn them back 40 years. Works great and they come out like new :) Keep on Keeping on Josh!
ROFLMAO! ToT?
@@willgallatin2802 Josh probably read the first sentence and then skipped the rest. Poor guy. He can't let that stuff get under his skin. Sometimes the suggestions can be helpful and provide different solutions to a problem, especially when you're wrestling with something, then other times it's just armchair quarterbacking!
Go Josh, you know what works the best from all you're experience. Very well put.
Thanks.
You did the right job on the trunion. The only thing i would have done different is putting the centerholes in first after clocking the part. Be carefull misting the anchor lube. Not all soaps are safe to breath.
I wish I had done that also. Hindsight. It is far safer than the Koolmist crap I was breathing. That stuff made me sick.
@@TopperMachineLLCI tried spray mist many years ago but had to stop using it. No matter how effective it was I just couldn’t stand breathing it. Surprisingly I’ve found plain old engine motor oil works very well in my 12x36 lathe. For many years I did a lot of diamond knurling on aluminum
and nothing worked as well as a flow of engine oil. The cheapest you can buy works as well as the most expensive.
I concur on your judgment call. A nice shave, and a nice tight pushing. Sounds like the best option.
Thanks 👍
Josh you dont need to explain your self you've done this long enough to know which is the right way to fix things. If they dont like it let them open ther shop and do it the way they want. Keep on kicking ass and moving forward. Love your videos.
You are 💯 correct on sleeving as a repair! I've repaired many myself and would never weld a trunion mount.
Thanks. That is Definitely not something to be welded.
After watching the video pressing on the bushings to the two ends of the shaft was the correct way ,must have had
.003 to .004 press fit on there after heating up the rings, that is strong enough to hold that ,actually would be even stronger than welding, when you weld something you take the strength out of one of the items and it does have a tendency of cracking. so you did the right way.
Never a dull day at Topper Machine..........
You’ve done over hundred never had a problem. I think I just might keep fixing them the same way as well 😂thanks josh 👍👍👍
Hello, I would keep the small lathe if I were you. We had 4 different lathes in our company and the smallest one wasn't used much, but the little beast was great, especially for small pieces. My boss was also faced with the question of giving away or overtaking. And We overtook her and she ran until the company was dissolved. And a good old machine is usually better made than the new machines. Greetings from Berlin
Congrats on 100K. I agree with sleaving the trunnions, welding is not always the answer. It didn't break with all that wear so a sleeve will definitely help. It also comes down to what the customers want. Make new replacement or repair. They pay for your skills and experience. I would love to do channel sticker trade.
send me an email. We can do a sticker swap.
Congratulations on 100K subs!
Thank you!
As a mechanical engineer, former rocket scientist, and amateur machinist, I have no concerns with how did this repair. Clearly, the issue was due to wear, not fatigue or overload. A proper, well thought out repair.
Thanks
Hi Josh, Love the Anchor lube, some things aren't worth answering, one of which I'm about to say. " Shit-can the small worn out Monarch, sell it to one of the criticizing internet warriors. Great channel, Thank You.
I gotta say, with regards to the Anchor Lube, I was a little wary about how many channels suddenly had it all at the same time. You tend to see random products come and go in waves across various channels and I'm usually unimpressed with most of them. I did decide to give the Anchor Lube a try in my home shop and I've been very happy with it. Any time I'm running into a situation where I have high tool pressure the anchor lube works like magic. It's a little more messy on the cleanup but I'm slowly transitioning over to it as well for most things.
I'd be very interested to see how your thinning it down and using it in the kool-mist setup and what kind of results you're getting.
Hi Josh & it's is Randy and i like yours video is cool & Thanks Josh & Friends Randy
bravo Josh....Keep that little Monarch..throw a coat of Monarch Paint on the Gal.....
make some Riser blocks....and let your incoming apprentices learn on the old Gal...
and Keep her as a Sentimental reminder of where you started.....
Unfortunately it doesn't serve much purpose anymore. Just too small for most work I do.
@@TopperMachineLLC
its the old saying " you can do small work on big lathe but you cannot do big work on a small lathe"
@@TopperMachineLLC Save it for theTopper Museum of Manual Machining!
Send it to Keith Rucker for a rebuilt and a re-scrape on the bed and crosslide.
@@stuarthardy4626 Yep, I've been looking for a bigger lathe, I have a Lablond Regal 13" but all the Lablond's have such a small spindle bore till you get up into the 20" plus, I have my Monarch 10EE for small stuff looking to get a 17-18" gap bed. Just missed out on a Andrychow TUG 40 18" with a 2.5 bore. I can kick myself for not making a decision sooner, buy the time I decided it was worth the drive to Wisconsin from Missouri someone else bought it!
I agree with Josh not welding the trunnion
Well if you do end up deciding to let go of the Monarch, I'm in Luck right down the road from you and might be very interested in that old beauty.
Sounds good.
Good explanation thank you
Thank you Josh!
Cool intercutting!
I was using that Anchor lube back in the mid 90s
The Monarchs are great lathes. I would be in the market for your old one, but I'm afraid shipping from you to me would be too much. I'll be on the look out for your video when you post it for sale. Maybe I just make a trip out there to pick it up!
It's funny how we can get it attached to a machine. If you have room to store the little lathe it might be worth it. One day you're going to retire or sell your business and you might want to have a small lathe in your home shop/garage.
I've come to the point that letting things go is much better for the business. I have a lot of years ahead of me to worry about retirement toys.
@@TopperMachineLLC fair enough.
Morning Josh,
Love seeing you talking abt upcoming projects and videos. Never even crossed my mind to thin the Anchor lube to use in the mister. What a great idea !!!!! I definitely need to try it like that. Can see Ill soon have to order a full case. Lighting, camera and sound improving all the time. Very very professional. Cpl small parts giving me a fit, frigged em up and having to redo, that happens as you know.
Don
Thanks Don. I've had to redo my share of parts. Worst are the small ones for me. I'm far better on big parts. Especially when it has a lot of money in material. You don't want to mess up. Lol
@@TopperMachineLLC These two are being a royal PIA to do...ugggggghhh...taking lots of time and patience.....
Everyone thinks you can just weld anything without any consideration of heat affected zone or brittle fracture. Unless you are desperate for the space I think you’ll regret letting that lathe go. That said I’ll be watching to see if I need to drive over there and relieve you of it. 😊
EDIT: Very interested in the thinned out anchorlube - hell of a neat idea. 👍👍
I think it will be ok to let it go. I don't do much small stuff so size isn't an issue. So far misting anchorlube has been great.
Someone will be glad to have the Green Machine for sure!
That lathe would be great for the next person starting out. I’m not sure I’d know how to run one that didn’t have at least a turn of backlash!!
You were correct. The weld could have caused a catastrophic failure. My machinest would have made a new part.
It sounds like some interesting videos coming up soon. With it getting warmer over there now, you might be getting back onto the sawmill shed soon? That will be a big project and hopefully you can fit in in somewhere between all the work coming in.
I sure hope so. It needs to get done.
Naysayers are retreating 😮.
Good machine tools are expensive, one man job shop can manage with 2 lathes if the jobs dont range from very small to large?
But as you state, tired and inaccurate equipment need to be gone, tgats my 2 pence worth Josh.
Nice insight 👌
Very true
Nice Blue angle plate you have against the wall. Is that a new score?
I've had it for a couple years.
I know I heard your video about that as well because I watched them all but you had made the comment in this video about being low on content for us because you have all the secret projects going on that you’re not allowed to show so I was thinking, maybe you could do some on your crane so that you would have content that you could show us Just an idea no problem I understand pain jobs have to be first. 😊
The crane is a personal project so it gets pushed back during paying jobs. It is just fill in work, but will make great content when there is time.
I like your thoughts about Anchor Lube. Is it a plastic allowing water dilution? Can you tell why it conducts heat away from cutter? I like your fix on the trunion
I'm still experimenting with thinning, but I've seen great results
Josh
a question about anchor lube ( here in the UK there is only one supplier ) I have heard that its a water based product and some people have found if not cleaned up after use it can cause black marks on steel ( some have said the etch deep and are difficult to remove
I would like to hear your view on this Joe Pie did a talk about this issue
as I have a very small hobby workshop cutting oil filled the place up in a nano second
It will stain, but the benefits far outweigh that. Just clean it up right after. I have not seen black staining, more white to gray.
@@TopperMachineLLC thanks for your reply
Morning
Don’t even respond to the internet experts . Just do your thing and keep going .
We ask question it generates videos lol
Anchor lube better have a good source of fairy wings and unicorn horn ! Thanks for the video
It sure has impressed me.
@@TopperMachineLLC used it back in the mid 60s... dilute 1 to 1 max was the rule, tried it in a greater dilution as a mist as you do now and discovered it needs a surfactant as an addition, cut it with a jet dry type product (actually photo dry) and it worded well. Problem was it did rust, or stain via capillary action so make use of way oil and/or wd40 for protection before and dewatering after. It was a pain in the butt to clean up when this thin as well. Usage as a flood coolant was never considered since the lathes were WWII vintage and no one had shown them love or upkeep in the job shops I frequented then. You can imagine the places that flood coolant could get into on a lathe! And as a mist it was very controlled and contained since it was not my equipment. Folks thought I was strange then, and still!
One thing to strongly consider before selling your smaller lathe is that having two lathes can be a life saver in a job shop as more chances of having an open lathe as the other may be set up with a, or for a job. Example work for the crane Connor is doing in the background on one lathe.
I've weighed the options. I have 3 lathes currently and only use 2 at a time. Honestly,there isn't enough work in my region to justify all 3. If things ever change, I can purchase another one, but the floor space is far more valuable right now.
@@TopperMachineLLC Got it, I didn't know you had 3...yep shop space is also a premium for sure.
Do it right the first time!!
Just a quick comment, mainly for the algorithm, I turned my 3rd worn lathe into a welding rotator. I would have done the trunion the same way, I hate welding anything that has been exposed to oil and grease over the years. Cheers
What ratio of Anchor Lube do you use with the mister? Have you had any issues with flash rusting since switching?
Stay tuned. I'm still experimenting, but will eventually do a video on the results
In regards to the small lathe. It has been my experience that I regret selling machines I never regret keeping machines. Just saying very faithful subscriber take care.
I get it, but I am a business and need to look at it from a money aspect. I regret selling some equipment in the past, but the benefit was worth letting go.
@@TopperMachineLLC Of curse I understand. You have to do what is best for you.
@@TopperMachineLLC Now, if you could find a smaller Hardinge precision in good order😉
@@alan-sk7ky had one. Kind of useless for what I do.
@@TopperMachineLLC 😃
Any time I'm considering selling a machine, the decision usually revolves around what can I do with the space gained or am I replacing it with something objectively better.
Exactly. Space is the big factor.
Josh, what is that big green beast behind you, next to the vertical shaper?
And yes, it will tug at your heart to say goodbye to your faithful old steed. I hope it gets a good home.
That is the radial drill. I've had it in a few videos. It will be sad to say good bye. I've had to do it with a few machines now.
Keep the little monarch it is payed for it self time will come when the new machine breaks then what do you do build a set of risers to raise it up to a comfortable height??
It is really too small for my work.
Is the wall behind the blue angle plate by the slotter the north exterior wall?
No, west wall. North is behind the planer, radial drill and right side of slotter.
intersting about the anchor lube. do you have a sponsorship with them? several other machining youtubers have switched to them too, it seems.
I do, but I'd use it without their support
That's great. Do you have the sponsored content tag on your videos that use it?
Yes.
Another benefit is that the bushing acts as a sacrificial bearing surface. Once it wears out, R&R and good as new. Can't do that with a weld. Cheers.
Exactly
100K subscriber what is the prize?? clean up the shop, paint a machine. play with the drag line digger? i would do all for FREE! if i lived nearby but Nevada is a long way away! congrats on 100K!!
You're still welcome to do those things. Lol. Thanks.
I didn't think there was any other way to repair that trunnion, other than how you did it. Welding would have been out of the question, because the part was too small and too complex to repair that way, with the risk of damage. Bushing it was the only way to repair it successfully. Had I been in a position to do that repair, I would have done it the same way. Of course I don't have the equipment for that, but if I did ......
What is the bore size of the small Monarch you may sell?
It's either 1.375 or 1.625"
What are you using to thin the AnchorLube?
Water
I saw nothing wrong with the way the repair was done. If the price is right I'd be interested in the little Monarch.
If you do decide to part with the little Monarch, ballpark price?
Not sure yet. It will be fully tooled.
I’m just curious when you might get back to making the stuff that you showed us a few videos ago for your track crane that you’re repairing I guess it’s for yourself that Connor was working on and you said he wasn’t gonna be with you much longer because he’s graduating but I figured maybe you might be doing more of making that those parts that’s another video group that you could put together I would be interested in all the things you’re doing with it Well just an idea
The crane is a personal project and paying jobs take priority over that. I am working on it, just at an as time permits pace.
Just fix them how the way you do Josh.
Keep the lathe as times you will not be able to break the big one down..
I have 2 big ones, and this one is really too small
Do it your way and politely hear the sideline chatter. There are scores of techniques for every repair/build out and an experienced aficionado like yourself has the edge over most others.
My shop needs lights, bad, bad, bad, bad.... a few people have fell between the cracks, as people do, but looking forward to the day, we can work without flashlights, lol
WOW the simple fact that you had to make an entire video just to explain yourself makes NO sense. YOU ARE THE EXPERT so people should be taking advice from you who's been doing this stuff for more years then most folks watching you. Well done but it's pretty sad that people think they know more than the Expert.
I do these follow-up videos mostly to cover what I missed and answer questions. But you are right.
I am going to do what I seem to do best; open my mouth and put a foot in it. Here goes: EXPERT--- X in math, science, and engineering is an unknown quantity, SPURT is a drip under pressure.
Can't get rid of the first lathe, set it off to the side and when things get slow do a rebuild of it for the chanel!
Real estate is far more valuable than sentiment.
😎👍😎
.
Ok can’t believe you actually have to explain yourself.
I'm basically just explaining why I do it this way. There are many methods, but the way I do it has experience behind it and I'm willing to share that. Also, it clears up questions that weren't answered in the video.
Emotional Attachment..... totally see that. Maybe you should re-watch some of your video's where you discuss how "machines are a consumable". Might help you get over that emotional part.
You like projects...ever considered rebuilding it? That would be interesting. Although I'm guessing it won't give you the return on your investment when selling....but that might also make you want to keep it again.
This is the only machine that has that attachment, being the first one I ever bought. It will have to go away. I don't need any more projects.
If there’s no stress on it then why did it wear out the way it did
Years of rocking motion and lack of maintenance
Comment about trunnion repair. Why did you make the sleeves before you knew what was required to clean up the trunnions? TOO much heat, it does not require that much heat to make steel grow, too much heat can change the chemistry of the steel. A retired heavy equipment mechanic w/50+ years in the trade
I measured it and knew how much I was taking off. I knew finishing the OD of the trunnion would be simpler than the ID of that tiny sleeve. It was a tight fit, I needed to make sure it was going. Never had a problem with heating them that much. 25 years doing these exact repairs with 100% success rate.
You shouldn't have to justify why you do things the way you do. I wouldn't even give the haters the time of day.
I do these follow-up videos to help the non haters learn. I often miss things in the video that I can cover more directly by replying to the comments here. Maybe the haters will learn something, but I doubt it.
No need to justify doing it right the first time!
There’s always 1000 ways to fix something . You’re method is just one way and is the you choose . If it works what difference does it make . Just saying
Absolutely
Thanks for the video. I think that it is great that you know when you can weld and when you can not. I think that welding is the answer for everything but I would have got this one wrong. Sorry man but welding is just glue to me. I am glad to see that you done some upgrades. Your shop is small so you have to make the best use of the space that you have. Good job on the video and good to see you.
Not every job is a candidate for weld. Or duct tape for that matter.
@@TopperMachineLLC you mean duck tape is not always the best answer? Tell me it ain't so, Josh...
Sometimes it takes electrical tape.
@@CothranMike Well, I guess todays video has all kinds surprises.
@@TopperMachineLLC What ever you do, do not tell the guys on the PBS "Red Green" show where Duct Tape is the always the answer. 🤣🤣🤣🤣
