70 Ton Friction Press Shaft Part 1 : Rough Turning
HTML-код
- Опубликовано: 18 авг 2022
- This will be a multi-part video about a shaft I machined for Blacksmith Tools. This shaft is for a 70 ton friction press Andrew is working on. The original shaft got bent during it's move so it needed to be replaced. In this video we'll get it all roughed in using our Precision Matthews TL-1660 manual lathe. The next video will show getting the shaft finished to size including the threaded sections. Last video will show the keyways being machined.

This is the classic Abom79 video. A long shaft, journals, keys, threads, all the elements of a true Adam Booth machining video.
A bread n butter special 🙂
In sweden you would get fired on the spot if you did what a79 did. Safety will always be #1.
And yet people will still bitch in the comments...
Mr.Sycho, what was done unsafe?
@@edwardkawecki8101 The lathe hasn't been leveled to within 1/10 thou (just like he did with the counter weight on his Kubota). Obviously not safe.
13:50 The people who complain about you sharing the process of indicating seem like the same sort who would complain when Bob Ross paints another happy little tree in his masterpieces (missing the point entirely). Thanks for sharing your craft with us, sir. It's inspiring to see an artist at play.
Bob Ross always repeated every sentance
And yet everyone loved watching him paint, and still does to this day
@@Abom79 Bob was great. Bob was great.
I predominantly listen to your vids and MAN that new shop is quiet. No sirens, road noise, Dodge Chargers, etc. It must be a dream for you!
The thing I like the most about his videos is that he is explaining what he is doing. It really makes a difference
This may sound like a silly suggestion, but for those of us who have no legit training with stuff like this, can you do a video that covers your process that you use to clean up at each end of the day? I know it may seem boring to lots of people, but I think it's also one of those sort of questions that nobody asks but many wonder about.
Among those things, it would also be interesting to know what you do with all your swarf.
I just realised, Abom is not just an awesome machinist, he is also a very good camera operator and video producer. There are no bad or uninteresting camera shots, everything you could wonder about is explained, and it is professionally edited.
Are you trying out sarcasm, satire, or idiocy? Maybe you've a case of SFB?
Anders - I agree! It's pretty obvious he has taken his production seriously over the years, constantly improving.
Well another peaceful breakfast watching Mr Abom79 work his excellent magic, while enjoying 3 eggs sunny side up and a garlic knot. Love ur knowledge and skill.
Yea the old Adam is back! Boy I can't believe how much I missed these real machining videos. Adams shaft turning experience is amazing. Thank you Mr Booth. Keep them coming.
I love the indicating. That is why I subscribed. That is why I joined Patreon to support this channel. I can _not_ express how much I enjoy seeing every single second of "indicating", in real time. Never ever stop showing _all_ of the indicating. Watch the needle at 14:50. Not a quiver. That is amazing.
Awesome! Thanks for the Friday afternoon video, it goes perfect with a Friday CEE video!
You do the dialing in so... robotically, it's relaxing to watch, it's like watching a "precision" CNC machine operating. (hint,hint) LOL I remember the big stuff, you always get that part done so well, no matter the size. In 1972, I got to watch the giant ships crankshaft lathe/grinder in a Sasebo, Japan shipyard, it was programmed and run by punch cards. I had tea with the operators in their luxury work station, very formal and proper. None of those guys could do that that work on manual equipment, there was a 70 year old master machinist that ran things, he was an apprentice and worked on the Yamato battleship.
It really is satisfying watching you indicating and setup a part to work on. It's even more satisfying to practice at home and see how all i've learned from watching your video's is working out really good for me. Thanks for that!!!!
I subscribed back when you had very low subscribers. I think less than 100k. I am still here, but I miss your garage shop videos. Super happy that you are on the up and up and got the new shop. However if you were to do an "Old shop thursdays" series I think you would do well and a lot of us long time subscribers would love it. Think on it.
Was actually just thinking about the indicating. Hopefully taking some classes in the fall(!!), but right now I mostly watch for entertainment. The indicating makes the process feel complete. It's kind of silly but I feel like I want to "make sure" the part is going to come out to spec along with you. 🤣😁 If the classes work out I'm sure it will be even more helpful when I try to do this myself. Enjoying the videos as always.
Just occured to me that Fireball should offer a laser etcihing option on those tables. A couple of full-length scales across the top would be handy.
14:39 When I was at the power plant (on construction and assembly) Part of my job as running this tired old lathe :) .. I put the 4 jaw on it the first job I did, and never took it off :) ... It also kept almost anyone else from using the lathe :)
:) 😀
I certainly am part of Team-"show the indicating". It’s very satisfying.
Yes I agree Adam - I love watching indicating 🙂
New video, yessss! I thoroughly enjoy your content. It's relaxing. Even the intro music.
Your work habits and methodology with the details of indicating, measuring and work holding is exactly what keeps me coming back. Thank you!
Adam I love your work I am a 72 year old mechanical engineer retired from a plant engineering career I have done it all as a jack of all and master of none from drafting welding matching if I lived in GA I would love to work with you as your apprentice for free just to learn your abilities you are very talented my friend!
Oh wow that shaft is the perfect apprentice/resumé type piece if you're looking for machining job, especially lathe focused. Long shaft, all sorts of features with keys, pins, threads etc.
I like seeing the indicating, not because i work in machining but because I don't - get to see a craftsman in his trade and i like to see the details.
For me, the setup, indicating and tooling are some of my favorite parts. There are so many ways to approach different situations, seeing some of the thought process is very helpful for me when I approach new projects. Thanks for sharing.
Man, do I love machine tools and workpieces shining brightly!👍😀
For roughing harder materials like your pre-hardened 4140 or even superalloys, I like to use the Iscar IC chipbreakers. Usually 80 deg geometry (cnmg or wnmg) or even 100 deg (cnmg). For finishing, I like the Kennametal CNGP KC inserts. (CNGP KC5010 is my go-to on Inconel 718)
Good ole Aboms machining. That's why we are here! Its always a pleasure to watch you work with the 4 jaw. Any chance you would put some of those insert numbers in the description or link them in your store? Thanks again!!
Put the centre in your lathe and run an indicator along it while its spinning. If the needle isn't bouncing at any point along the length then check the tapper angle. Maybe the piece you pressed in caused a slight deformation in the taper
I’ve always wanted to see how I’d do centering something in a 4 jaw. You make it look easy but I bet it would take me the better part of an afternoon to get it done 😜
Don't hurry and it will come to you, it's not hard to do at all.
It takes a while at first but it's a fun Challenge and before you know it you'll be doing it in no time
I've also found that his indicator in front technique is just a little trickier. I always set it up on top and just adjust the top jaw.
Loooove the fireball table!!!!!!!
Seriously! He did wonderful designing that table and I love how he goes through all the features he wanted for it in his video
That new lathe is unnaturally quiet, its a true beast...
I’d dipped out of RUclips for a while so have missed a lot. Great to see the new shop up and running. I’m also firmly in the “show the indicating” camp.
At age 17, I had the opportunity the understurdy a crankshaft grinder as part of my training as a motor mechanic and seeing you do those indication, gives me such great pleasure. At almost 60 years, I find the indicating technic very nostalgic and therapeutic. Thank you bro Adam.
Fast forward is there for the impatient. Play is there for those who are along for the whole ride.
It's awesome and somewhat reassuring to see someone actually DEMONSTRATE how accurate the human eye is using a simple scale and being able to differentiate and resolve 1/64th inch, or for the machinists among us, 0.0156, 0r 156 TEN THOUSANDTHS of an inch.. YES, I can split those hairs THAT fine, just by eye, it just takes a bit of practice, and time on the job.. Awesome stuff. Git it!!
Finally someone giving the tape measure and a keen eye the respect they deserve. Been taking some precise tape measurements for years!!
I miss the videos of you making those huge shafts at your old job
Physics. Gotta take into account bending moment, force of cut, etc, etc, etc. Amazing how well you manage all those variables.
Adam, everyone of your vids is a learning experience! Wonderful work as always.
Eric
Great content. When I think how I came to your channel, a This Old Tony video that had a funny cameo of yours, I feel so lucky to have found your channel. I enjoy watching the indicating and setups you employ. I’m not a machinist but really enjoy seeing you make and fix things. Your delivery is a big part of why I enjoy your content.
Adam, you are a very good teacher. I really appreciate the time and effort you put into your videos and sharing your knowledge and expertise.
Big stuff (-! Abom79 was the first RUclips channel where I saw big pieces being machined.
Nice video. I like the way you explain about different types of inserts and why you choose one over the other. And I agree with other viewers about the quality of the video production. Top notch!
I think a lot of the talk about inserts is related to product placement.
Abom79, everyone knows you’re a leading indicator! 🤪
For me the most comfortable way to measure a shaft like that would be to get out the ol' 61"-62" micrometer and measure it (I don't trust v blocks on a table like that so I would hold the shaft in one hand and the mic in the other)
Yes that's the way to go for sure😁
Great stuff, that FT table is outstanding, I thought you'd chop the sticker end off to keep in your scrap pile 😀
Nice work, Adam. I've never seen a follower rest in use until now. I am glad you are enjoying using the new PM lathe. Thanks for sharing.
The old 10 thousands ground eyeball measurement method! It does work. Just expect to be using a magnifier in your later years Adam.
That follow rest seems a good choise. New stuff is not worse always.
Awesome setup
great to see you in the new workshop. cheers Trevor from oz
Appreciate you booth. Always learn something good from you
Just got my espresso, time to watch some Abom! Best start to my weekend so far!
Another great show. Thank you!
I was told 65 years ago by my Father ..3 jaw chucks are for holding hex stock...I always use a four jaw...Made things easer dialing in a four jaw... mark your chuck with Dykem on # 1 and #2 ...Helps not getting confuse witch jaw you loosen.......Robbie
It's good to see paying work come into the new shop, I hope many more jobs come your way, and as always great video
“Stickers don’t smell good when you machine them.” LOL!
this comment isn't just for Adam its for anyone doing longer skinnier shafting.
if you need precision you should really be checking the deflection of the steady when you set it up. a job this long will have a small sag to the middle. so just touching the rollers to it will have it a little low. putting your DTI magnetized to the job and indicating against the chuck you will see how much the shaft is being moved by the steady. example if the back roller is a little high and front a little low all 3 will still be making contact but the shaft will be pushed slightly forwards meaning you will cut a slight taper to your workpiece, the same as if the tailstock were misaligned.
also any vibration on the steady will be amplified in the cut. so be sure to get a better surface finish than you need on the bearing surface also be sure to oil the bearing if it galls the shaft it will quickly ruin your whole weekend.
That is good to know as i am new to all of this.
When you mention indicating against the chuck, will that show sag when you turn it from top to bottom?
Reminds me of your all "classic" videos.
Man, I really enjoy watch you indicate. Probably, because I'm not the one doing it. Haha!
Enjoyed watching this episode
19:00 - to help with fine chips going everywhere issue. Collect all empty cans, card board, old shims just anything really that can be cut into a sort of L shape. Put it in with your tool holder, clamp it and manipulate into a position that’ll make the chips follow a curve downward path into the chip pan, you’ll have very minimal chips find their way out of the machine
Boy thats some tough material can tell by ear watching those chips being made. Awesome job
Yup, pre-hardened 4140 is tough all right.
Coat the live center's shaft in dykem and insert it into your talestock to see where it is touching. The plug you pressed into it might have bulged the end of the taper preventing it from seating.
I'd use Prussian Blue, but I think we all are thinking along the same lines.
That new lathe is great!
When I saw those chips flying everywhere I was wondering if you had some kind of plastic shield attachment. Surprised how much better the different insert did.
Your ausio with that lovely lathe is now awesome!
Cool job! Looks fun!
I learned how to 4 jaw indicate in high school. The shop teacher showed me how to run the lathe and whenever he wanted anything important set up in the machine, he would only let me indicate it in. Then in college for heavy diesel, we had to take a machine shop course. That was way back in 78 and 80. I still to this day use welding and machine shop techniques when doing projects around the house, on vehicles, tractors and equipment.
Nice to see you flinging some chips in the new shop.
I love your setups, I transfer the principal to wood work on my lathes
Just saw the repaired press in action..works like a champ.
Really enjoyed this one.
Wonderful closeup shots Adam!
No complaints from me,thanks for the video and tips🤗😎🤗😎
11:00 you have some super equipment😍. Very nice new shop.
Did that button you pressed into the end flair the end of the taper just hair perhaps? Just enough to unseat the the small end and reduce the contact area.
Oooo, that'll do it.
Man, that welding table is nice.
Awesome. Thanks for sharing!
Great job so far Adam, looking forward to your next video!! Oh, and I'm glad to see the old faithful on your wrist again, no one actually knows if the last one was american or swiss made. Good choice.👍👍
Nice table!
Great video.Thank you.
Thanks for the honest eval.
Thanks for sharing 👍
Holey table Batman!
Really Enjoyed!! Well said! Well Done, Cheers!;-)!
Thanks for sharing buddy
Great video, thanks!
Love the indexing! Also, wow that is hard stock. I’ve never seen chips fly like that in your vids.
I’d send that live center back Adam.
Hello to Abby,stay safe and take care! God bless!🙏🎚🇲🇾🇲🇾🇲🇾
Like all the info thanks for sharing
Nice, true work.
Thanks for the sharing
This is going to be an interesting job. My first thought, though, is "Could Keith Fenner straighten this?" I've seen several videos of him straightening marine shafting. Maybe he could look at the old shaft as a backup.
26:32 - I love how you let the shaft rest and de-stress overnight. It’s very considerate of you to let it chill out like that and relax. Did you find a pillow for the head end? 🛏
No, he didn't. But he has another shaft for your tail end.
Psychos is a total AH TROLL !
@@edwardkawecki8101 No need to be a racist.
Muy buen trabajo maestro bendiciones en este día y muchas gracias por sus concejos tan útiles.
Excellent.
i have watchified many a bum and other turning vids and this is the first one i have seen that features the follow rest
You've watch many a bum? hobby?
Ha, surely you mean abom... but the rest in question is rather a forward rest. A follow rest is behind the cutting tool and a carry rest travels right at the cut, both ahead and behind with all the hassle in adjustments that brings.
@@colinfahidi9983 there are lots of bums where i live.
@@CothranMike or is it a rest that follows along the carriage?
The JBL speaker...yeah baby! I love those things.
That would have been a nice job for the CNC lathe. Unbelievable finish you get. Sweet.
I have a slight knowledge of what you’re doing but I really enjoy watching your video’s very cathartic.
I know don't leave the key in the chuck.
