SNS 337 Part 1: Knuckle Boom Pin Boss
HTML-код
- Опубликовано: 28 сен 2024
- This week we have a pin boss to machine for my buddy at the welding shop. This goes into a knuckle boom that is used to pick up trash. Part 1 will cover getting it set up in the lathe including use of the steady rest plus indicating it true and ready for boring.

You're at an unusual angle at the lathe save your back. That crane was a smart buy!
That is one very nice looking crane. Thinking how many different ways & mounts could be made to use off lathe.
Good on you for looking after your back. You know that straining your back can recover, and you think everything is OK again, but it is not. You may forget hurting your lower back but your back never forgets. The damage is permanent. So good on you.
Right from the first Abom79 video, Adam, you have shown the indicating process in *detail*. It is one of the best features of your videos. Thank you.
Yep! The logic of it is inescapable, repeatable and dependable - much like Mr. Booth.
And doing it twice to boot. Kind of surprised me that he didn't leave the bar out from the chuck jaws right at the start knowing that the tailstock end would need to be bumped around.
I really like how you explain what you are doing and why - so clearly. You remind me of my high school machine shop teacher who was a super guy and a true master of everything in the shop. He was calm, patient and a gentleman - and man, did he know his stuff - just like you Adam.
Please don’t ever apologize for your Sky Hook. Using your brain instead of you back should never need an explanation. I wrecked my back playing college football and everything I can still do requires thought, planning, and as much assistance as I can manage. Do everything you can to avoid back issues. Anybody that gives you flack about that can be ignored.
As a young man I worked for the Chrysler Co. here in Australia as an engine assembler and would fit crankshafts to the Cyl blocks all day lifting them by hand because it was quicker than using the clumsy hoist supplied.
40 years later and I'm now paying for that choice with a fragile lower back.
So to all those young "bucks" out there I say don't be a hero. Just because you can lift it doesn't mean it is a smart thing to do.
Cheers Eric
Sounds like you have had your fare share of opinions lately. No need to defend your way of doing things! Love your videos, keep up the great work!
It's not 'defending' it's educational discussion - which we all learn from - so is really appreciated.
Hello Adam
For me this videos where you take the time to explain how you do stuff is the best. Now i can benefit from your tree generation skills the next time i set up a large piece in the lathe. Thank you again and hope you will keep take the time to explain basic skills fo us hobbyists. Cheers
Just wanted to pipe in and say I appreciate the video we’ve got a great community of viewers here, something to be really proud of Adam.
Using the "Sky Hook" is smart!
If all of us with back issues had worked smarter from the beginning we wouldn't have so many back problems now! 👍
Adam........We can all see that you are a strong and fit young man you are also a Master Craftsman and I am so pleased to see you are not afraid to use mechanical aids to ensure you don't get problems when you reach my age(65) please continue to look after yourself and don't make apologies for using the skyhook its the most correct thing to do. It just shows how well you think of the trade you are in. Well done mate.
Abom, brains and friendliness packaged in a gentleman.
Always enjoy your videos. Mostly because of the way you explain what, how and why you do specific setup and operational tasks. Something I don't see from other channels. Thank you very much for sharing the vast amount of knowledge you have gained over years of skill development.
I do like the step by step explanations. Everything logical and for a purpose.
Thanks for explaining your thought process when you were bumping in the end. I've seen you do it a hundred times, but it never quite clicked how you measure a high and then roll it to an easier position to adjust it.
Also not great to bump towards the indicator. Precision measurement devices don't tend to like repeated shock forces applied to their mechanisms.
I'm repeating some other comments.thanks for talking through your thinking and methods.i learn better that way and need to keep seeing basics in different applications to grasp it proper. Cheers.ta.
Even in France we are watching this very good channel : C'est un cours parfait pour faire du très bon travail tout en préservant son dos. Bel exemple en prenant une pièce simple, mais avec la majorité des gestes du tourneur.
Those little jib cranes are amazing for swapping out chucks too. Real back savers!
Adam, your comments on how to set up a 4 jaw chuck with stock on the lathe are the best. I have never touched a lathe, probably never will, but I've learned so much from watching you about how to think about mechanical things. Thanks.
I have 4 different back injuries from poor working posture and lifting, I live with constant pain 24/7, I've had 6 operations so far (2 of which were surgery) and heading to my 7th procedure in a few days, I'd say the sky hook was your best investment yet. Kudos Adam, much love.
Yes, Adan, take care of yourself. We all actually get older, and eventually something gives way. The Sky Hook will push that day back by decades. You are one smart cookie to take care of yourself like that.
Those old Monarchs run so quiet. That’s such a sweet sound. What beautiful machinery.
I really like watching a craftsman ply his trade. I especially appreciate the verbal explanation as to why you are doing what you do. I'm way too old to ever use any of these tricks, but I love learning about them anyway.
Your planned, deliberate and methodical approach is wonderful to watch. No surprises because there SHOULDN'T be! A-B-C-D BOOM. done. Joyous to watch a true master. Thanks for making my Saturday morning Adam!!
Good the see the family photos return at the end of the videos. Nice job.
Good video - like the sky hook. Too bad it doesn't have a wheel on both sides - hey there is a little project for a rainy day! a SHAFT EXTENSION AND A WHEEL.
I really appreciate the extra "what I'm doing and why I'm doing it" approach.
Agreed!!!
InstaBlaster.
really great to see your method and thinking when setting up I found that really interesting. Great video as always!
Skyhook, work smarter, not harder.
No more power lifting for Adam! lol An old friend of mine said people get old. That is why we invented hydraulics. :-)
I agree adam about the skyhook. 28 years of tormenting my back. Last 1.5 years 3 back surgeries 2 fused and 2 laminectomy. Do anything to save your back.
Me too brother, 3 back & 1 neck surgery later and I'm done with doctors and neurosurgeons!
Saving your back is smart.. I'm 35 and I'm saving mine as well.. it's like when you see people using there hands to pound on stuff.. I was tought to never do that on the account your hands will be crippled later on..
Great videography again.
There's a second person there running the camera? Who IS that masked videographer??!?
@@mdouglaswray It must be Abby.
I normally watch on Saturday night, but went to bed early last night, so today I get a Abom79 double treat at lunch time
I'm 68 and worked on heavy equipment much of my working life.. I am now getting shots in my lower back for pain so trust me, I know... Cheers from Louisiana
You should get a second sky hook to remove the one mounted on the lathe
I really enjoyed how instructional you were on this SNS. It made for a richer episode. Makes me think I could actually machine a piece like this. 👍
The backs weakest range of motion are those slight forward angles of lean. Under load and you are asking for it. Abbys filming is so steady that I was surprised when the go pro started moving. Lol
Not a machinist myself, but really enjoying the video's. Keep being amazed at all the things to take into account before even starting the first cut.
I like that sky hook. Wish we had those 30 yrs ago. Many a machinist had back issue lifting those heavy pieces. I know I would have used it. I don't blame you for using it we only get one body in a lifetime so you should save it when you can.
Great work if you don’t take care of you, no one will for you! We do harm ups at work, i thought it was silly and halfway did it. I then saw someone go in cold and tore a bicep! It was about 30 lbs. we had to work a man down and he lost pay with doctor’s bills. He company eventually paid for it after an investigation. Your a one man army all you man. Thanks for sharing.
Very educational. Thank you, Adam.
That crane is a great idea my safety supervisor told me when your leaned over and lifting every 10 pounds is equivalent to 100 pounds of force on your lower back so that piece would be equivalent to 450 pounds of force on your lower back
Thank you Adam I always love watching your video I am from South Africa
Aangename kennis.
Knuckle Boom Pin Boss jam nitty gritty, you're machining with the guy from the big bad city.
Shout out to your wife on the awesome camera work!
the right tools make the objects precision
That Sky Hook is a great idea. I have had to sell my sawmill recently due to back issues. If you keep up this practice of avoiding unnecessary back strain then believe me, it will pay off.
You are very sensible to look after your back, I injured mine over 30 years ago and still have to visit the chropracter every few years. That episode went far too quickly love your channel.
Adam, Excellent presentation, you would have made a great shop teacher in another life. Thank You for your thorough explanations of your process and reasoning for each step in the process you make. Hopefully we can get more manufacturing back in the USA and grow the machining trade back where it was back in the 50's and 60's. Being a third generation machinist you have a wealth of knowledge that most people would never gain in a life time. Working for motion also provided some diverse projects for you to learn from. Work Safe & Take Care
These videos are so helpful. I work on a ship with a lathe and I know how to use it all thanks to you abom
Great job of explaining what your thought process is Adam. Thanks
Yo that skyhook thing is nice as! Good stuff
Your explanations remind me of my High School Machine Shop Instructor. Set up and ready to Rock and Roll.
Knuckle Boom Pin Boss sounds like an awesome band name.
Thanks for sharing with us Adam, Fred.👍👍👏🏻👏🏻
Love the explanations. I needed a refresher on steady rests anyway. Haven't used mine in a couple years.
I love when the steady-rest comes out!
Have to agree with others on back pain,,,I would like too have a Sky Hook to assist me, but affordably has me using a HF boom lift. Think my back surgeon will thank me too (@@). Lov too see big iron being turned,,,Now that I have moved up from a SB 9 to a LeBlond 17, can't wait to mount the 12" chuck and turn some dies for our Pexto 617,,, :)>, Thx for sharing Adam,,Bear.
I absolutely love this channel.
Thanks for the great content, Adam.
Hello Adam,
Nice work setting the part up in the 4 jaw... good to see you are protecting your lower back...
Take care.
Paul,,
In my business, a “‘hey man’ job” is know as an “oh, by the way”.
Or “just one more thing” as you’re walking out the door at the end of the day!
I'm with you on the lifting issues. With that big lathe you are lifting things relatively far away from your body. Instead of just up and down forces on your back there are rotational forces on the back. Those are the ones that usually get you.
Thanks Adam for sharing your time and talents. By the way using the sky hook is working smarter not harder.
Never to basic for me a non-machinist. Thanks for explaining how it is done.
I love all your videos. Great narration, awesome projects, plain ol smarts.. Keep it up 👍, with ❤️ from 🇨🇦
Great content thanks for sharing
"Hey Man"... take care of your back. Also your knees.
I like the skyhook, I just think you need an mini shop size gantry crane.
You are awesome!! Thank you for explaining everything!!
I love the sky hook!
Oh pardon me,hello Abby.
Knuckleboom Pinboss was my nickname on the high school bowling team.
James, that was just to your face; when you weren't around we always called you KnuckleHead Pinboss ;D
That you for showing us how you center work.
That sky hook is clever. I wonder if you can use it as a mounting point for the camera. 🤔
Saturday is always great your videos.
No need to explain using the crane. Anybody with any sense, no matter how strong, should understand why it's better than manually loading heavy objects like that. It's basically another set or 2 of hands 👍
Then again...considering what I've seen in the last 12 months, maybe you did need to explain it. 👎
yea he spend more than half of video explaining stuff.. i want more cutting, less talking. it becomming more of that laterly video he posted.. less and less. ugh
@@koford Beg to disagree, everyone gets different things from these videos, I'm sure. As someone who is not a master machinist, just seeing the work-piece spin around shedding chips looks pretty but isn't very educational (or interesting / entertaining). I very much appreciate his dialogs.
@@koford What do you learn from watching chips flying? The tips and techniques that Abom explains are a gold mine for anyone starting out with machine tools, definitely the most valuable part of his videos.
@@ferrumignis Most of it already been explained multiple times by Abom.
@@koford Not everyone has seen every video, there is always new stuff to learn. What's so fascinating with watching chips fly? You see it once and you know what it looks like.
Skyhook: working smarter not harder.
I firmly believe that the older geared head Monarch Lathes are the best lathe I ever operated. Solid, reliable, accurate, smooth operating, finely made machine!
garbage trucks are surprisingly heavy duty machines that almost everyone encounters but never gives a second thought about what's going on
Ecuador,saludos👍
Awesome job and video.
But how do you lift the sky hook ;)
nice mini crane, ooh! sky hook
Adam, have you ever tried 00 grease for steadies? I find it works a lot better than way oil, especially on Aluminum.
Also using the same indicator means you don't have to worry about any discrepancies in calibration between the two indicators.
If you have an indicator with that much discrepancy, get rid of it.
I would love to see abom would machine a line bored tube where the outside is still rough forged and the ends are saw cut. I machine that kind of material every day in my job and would love to see how he would set it up to make the inside run true in the lathe.
Enjoyed the setup and use of the Skyhook. I am curious about how you place and remove the Skyhook each time you need it. What picks it up to install it on the lathe?
Be Careful and Stay Safe.
Bob
Agree with saving your back. How much does the Skycrane weigh? Just wondering about moving it off and on.
You get a second skycrane to move the first one :D
He has a cart that moves up and down to transport it.
Skyhook is about 25lbs
Work piece is around 40lb
The work-piece without the hook would need you to use 1 hand for lifting while leaning to tighten the chuck - its the ergonomics not only the weight
I learned the importance of looking after your back recently when I felt some funny sensation when stupidly trying to life something that I should have had more assistance with; it's taken 2 months of avoiding heavy lifting for my back to return to normal so I can actually get proper sleep. I forget (I'm almost 50), that as you get older you will be more susceptible to injury. Sometimes in our workplace I think EGO plays a part in causing the guys to try to manage a certain amount of weight without proper technique and assistance, and sometimes, just moving something by lifting it yourself seems to be the 'quicker' solution, so it's sometimes a question of convenience, which is what I did (and look what resulted); Silly really, because if you put your back out, it's going to affect your ability to work and the your overall quality of life in other areas.
How do I find the indicator holder you used, "Rotodial"? All I found on the net is for phone systems
www.roto-dial.com his caption is not accurate in the video.
Once u have a bad back always a bad back anything to help abom I know from experience
Good Evening Adam, I really enjoy your channel, in this video can tell me specifically what is the tool holder you are using that allows you to use the CNMG insert on the short, I have been unable to locate this tool, any help would be great.
Wonderful more please
How much does the sky hook weigh? Seems like it would be heavier to load than the part
23 lbs.
The "Tool Post Mount Sky Hook" weights only 23 lb
it's called working smarter not harder things that come with age
Is it just me, or does the detent on the Skyhook sound like a dolphin?
Have you considered upgrading your steady rest, from brass pads, to roller bearings?
I guess it'll depend how much he uses it - it didn't look very worn - so he's clearly happy giving it a squirt of oil. It'll outlast him !
roller bearings add another variable to account for in machining tolerances
@@bengrogan9710 You mean through out of roundness ?
@@millomweb In any roller bearing there will always be some small degree of play to allow the rollers to move freely
any additional layers allow that play to build up and it only takes a few tenths of play to allow for chatter in the finish of a surface
@@bengrogan9710 Except for the fact the rest clamps against the work - offering a means to remove all that play.
ur a smart man coming from a bad back
What about making one of those tail stock chucks like cutting edge engineering made?
That tubing is almost as big as my lathe😂
Why is the thread from the steadyrest left handed?
So it can go righty-tighty, like a vise.
Oh I see what you mean now. The threads are in fact NOT left handed, that's why you have to turn them CCW to make the jaw move forward.
Its a two part "screw". The thumb screw and the brass part. As he screws it out (left turn) the brass parts gets pushed out. That is because normally when you unscrew a screw left turn a screw would come out of its hole. But here it stays in position and the opposite side goes out. Hope its understandable. Bit hard to explain.
@@waynejohnson1500 thank you i understod it well
