- Go to 9 minute mark for the machine work footage.
This week I have some footage from work. First job is a Heli-coil thread repair job in an aluminum housing, fixing an oil drain plug hole.
Second up is some shaft couplings I machined from 11" solid 1045 steel round stock. These are some custom sized couplings that had to be machined to the sample size. I do some heavy rough turning, taking 1/2" passes using my Iscar tooling designed for heavy stock removal. I'll finish up on the mill with some drilling and tapping.

what SFX software do you use to make those big chips?

Sorry to hear about how contractors treated you poorly. I have found that contractors are allergic to Vibram soles and the application of them to the posterior region of their body. I truly enjoy your channel. I'm an amateur machinist and subscriber and feel like a kid at Christmas when you post. God bless, my friend.
Work is letting you record again? That's good of them. I missed the work vids - but I understand that it's their call.

Adam,
You have stated many times over the last couple of years that you really need flood coolant on that machine. What is the problem with your employer buying what you need?? You're already saving them a bunch of money by using your own boring bars, carbide, etc. The bottom line is that they need to step up and get you what you need. You've already been giving them free advertising on TH-cam the last two or three years...
Regards,
Shawn
Shawn McPeak If you really need flood coolant, just head down to Texas.
Robert Storms says Mr. STORMS lol
It´s just the same as in every workshop. Save money here save money there, just most of the time in the wrong place.
Also could be pretty hard do set up flood coolant on a machine that didn´t have it before.

Shawn McPeak it's not always financially realistic. Many shops around the world struggle to keep the lights on these days. Even the large established companies feel the crunch.
Wow! Chris really hooked you up! Must be few hundred bucks worth there.
More like a few thousand. Quite the yard sale find.
Stock removal at its finest...nice to see some footage from motion
man I never find stuff at garage sales like yall do...
Adam, thank your work place for us!
Amen- My machinist-bone is satisfied for the next 5 min....
Love the heavy metal removal. Always impressive. Hope the new contractor does all that you need done, and on time!
Great camera work on the flanges, just like being there...Dave
Work clips! The old pacemaker sure is a mule. She cuts pretty straight? Thanks for sharing, Abom
.600 wow, I feel like a man taking .200.
video has been on for 9 minutes and already has over 200 views....getn popular boss.
travnturner We had 4K in the first hour according to the analytics. 👍🏻
I talk for myself. I always keep my phone near just to ear the bell ring saying: "new video from Adam". kkkkkk
You are the only channel that shows a commercial shop, we can all learn from the pro's and take those lessons back to our home shops, thanks for sharing.
With so many donated/extra inserts and tooling to spare, I'd love to see a series on more Abom sized common mistakes/machining don'ts!
I see so many people on you tube that are afraid to make a heavy cut.You and keith fenner aren't afraid to make that sob grunt. Time is money.
Loved the footage from work! That lathe is quite a machine.
very good you lathe machine work I'm farhan I work Saudi Arabia
helicoil tip when there is no install tool .. drill and run the helicoil tap thru a hex nut.. sometimes one side larger than the actual thread size.. you can now preinstall the helicoil winding into the nut and then hold the nut in front of the opening to wind it into. i use this a lot on 3.1 and 3.4 gm engines while installed on the rocker arm hold down bosses. just a quick tip..
I got a kick out of you Machining with that toothpick in your mouth. Joe badass. One of my mentors used to do the same thing. It brought me back. Thanks!
J P Must have been after lunch, just a minor habit I have.
Awesome video Adam,
Have you ever thought of putting some of those massive pretty blue chips in a bottle and selling them?????
Thanks for sharing.
Steve,
What you don't want is for one of those big scalding hot blue chips to spring off and hit you in the neck! You can always tell a long time lathe operator by checking out the burn scars on his arms.
4 words - limited edition framed prints. Just sayin...
yep , i still have a scar from 30yrs ago 2'' below my belly button , was to scared to rip open my shirt in case it dropped to the family jewels !
I have a few side projects that could use them.... Been thinking about that-
Steve W. How would you season them?
They look like some parts I make at work keep up the great content.
Glad to see you posting work videos again, I like the home shop stuff but stuff you do at work are something else
Hope that you're enjoying the making of these videos as I enjoy watching and learning from them.
Good video Adam
Heavy cuts oh yeah! I guess it bogged more with the .500 cut than the 600 cut because it was a much larger diameter part at that point or did you change feed rate?
+bcbloc02 I believe for the .600 cut I backed off to the .022" feed. I'm actually afraid of something breaking, like the keyways inside the gear that the feed rod slides through. I want to push the machine harder but fear of something messing up.
In that high feed testing video I did way back when I took .188"DOC at .60 feed rate. I actually did it again with .100" feed rate but the tool pushed back in the holder from the force and only wound up taking like .140"DOC. Still I think you should be safe up to .040"feed that is about the max rating for an 643 sized insert with an RN chipbreaker anyways.
Abom79 you dont kno what it will take till you break something thats why they make shear keys
I just love my Saturday evening SNS. Cheers!
That's got to be the best 5 bucks yard sale box of all time!!!
We enjoyed Adam ! EPIC HEAVY TURNING .Awesome share man .. Thumbs up man..
Watched in my new 55" TV. A different experience, but I don't think the AndroidTV TH-cam app doesn't play at HD level. I may have to try via the web bowser app; although I may be limited to 720p with my internet connection. You had some great footage from work.
Nice episode as usual! Am I the only one who half expects a kitten meow or lion roar (or something) at the end of the final music? Like the music at the end of the movie? Lol...
Why do people dislike this? It's not a lot but still. The title isn't misleading, they're not being forced to watch, I don't see anything wrong (safety & technique ect.) If they don't like it don't watch it. But I enjoy watching and learning from this.
+Tyler Davis As mentioned in other comments, some people feel entitled to watch videos with nothing but machining content in them. I can't please everyone, but I can make the videos I want to make.
Abom79 Thx.
Awesome stuff Adam! I love my LNMX tool for heavy removal, thanks for showing it way back when!
Thanks Motion
Yes on travel videos, they are fun to watch.
Building watch, more to come,Yes!
Liking the info inserts into the footage (you got todo what you got to do!) and the next episode teaser. Thanks for sharing big chap. Kindest regards. Joe.
I just purchased that exact same broach set. Minus the metrics. It looks new and only 1 cutter had been used.
Keep these great vids coming brother. Been watching for years now I am gunna be commenting more 👍👍🇺🇸🇺🇸
That was an interesting project; looking forward to the rest and the teaser of coming up projects. Also, I'm looking forward to the travel videos, Greg.
You say using Armstrong technique. I do it with the handraulic technique. 😁
Awesome machining. I really like when you describe what's going on, like the doc with lathe. Thank you! :)
Pacemaker vs. LNMX: PACEMAKER WINS
Pacemaker vs. Giant Freakin' ISCAR Hog-It-Off Insert...
~>XD
Iscar have a range of unconventional insert geometries. Their lathe inserts in ISO geometries are OK but their in-house lathe and milling inserts are behind the game.
Heh. I was mainly just making color-commentary. Adam gets to do things I can only daydream about. ~:)P
Great video!!! Thank you Adam!!
16:41. Damn. Turned the toolpost. Which I'm sure was Abom torqued. You could tighten the clutch lever on ours with a 5 foot pipe and it wouldn't do that, and that's probably a good thing. 26:00 I've never heard the pacemaker bog until now. Is it a 20hp machine? You gotta respect that Pacemaker for being able to work hard for 75 years and be ready to do it again, day after day. What a great machine built by great men who loved both their job and their country.
The Metal Butcher I don't know exactly the HP. I've never gotten down in where the motor is. I think it's a 20-25 HP MOTOR.
when did the boss let you start filming at work again
Dang...that's one nice chipload there! Really makin' her work hard!
What a great gift, the broach set - wow... and all those inserts too! Wish I could find a viewer who is that generous!!
250 off one side - you are indeed the deep cut master! Big rigid machines sure help!
Nice results Adam.
love how the chips turn blue
$5 for a box of carbide? Holy crap that’s a steal!
Hi Adam,
Nice Job! That Iscar rougher was sweet. That insert had nice chip control. Was most of the heat in the chips or did a lot of heat transfer to the part?
Steve
I enjoy all your video productions every single moment
I like the box you throw up with the feed and speed rates.
You know, if that mist is killing your microphone, it probably isn't doing your lungs any good. When those misters came out, we bought one, I used it once and said never again. I figured it was bad enough that my hands got soaked in soluble oil when running the turret lathe, I didn't need my lungs getting coated when running the mill.
445supermag modern cutting fluid shouldn't bother you much
I have never liked helicoils.Keenserts are better but, I like to drill and tap fine thread allen head cap screws. I can make them as long as I wish. I would make several of the most common sizes that I used at work.Run them in with Locktite 272.Cut it off flush.When possible,and time was not a problem,welding up the hole then drill and tap
Very enjoyable Adam, nice chips!
Now THAT's some major chip generation ... actually, more like chunks.
Dang that box of carbides and mills is easily over $1000 worth of tools! Wish I could find that many for $5 🤣
Love the channel you Ave and Cody's lab are my favorite.
have you heard of hexagonal turret lathes? we have 4 of them at my shop, 2 of them are warner and swasey 4A, one is an older model warner and swasey, and then a gisholt 5L. we mostly do rough cut trepan drilling, of continuous cast iron, but id like to be able to do more with the machines we have, for replacement parts, as certain things are hard to come by for these old machines. any ideas on what i can do with these machines?
Cannot be the USB-connection, if there is only one channel: Possibly the microphones itself gave in to the moisture and then started to dry up.
Has the idea of putting heat sink compound between the insert and the insert holder ever been tried. Seems like it would transfer the heat away from the insert better. You know the white paste they use for heat transfer on some electronics. Probably too high a temp and the compound would just burn up.
78F is "nice and comfortable"? Man.. I have a 71F melting point..
It's been way too long since I watched a video.
...too bad there isn't another way to remove all that excess metal without turning it all into chips(!)
Listen to that Abom Torque Load.
26:02 I could swear I saw the lights dim, dam..
Really like the little box you put in @ 26:17 .
Beautiful machine work on those couplings. On your countersink or chamfer bits, i noticed it looked like you were using a multi flute tool. I have a couple of those but also some single flute ones. I find sometimes the single flute ones don't cut an even chamfer... but the multi-flute ones always do. Any thoughts ?
Ramsey Customs - turbocobra I like the consistency of the multiflute chamfer tools. Most of what I have is uni flutes though. I don't like how they pull the cutter off center.
helicoil ......like helicopter.....not heeliecoil ....lol....yeah , i know , who cares ..haha..
Lol you sure don’t like breaking chips when tapping do ya? 🤣
iscar recommends up to .259 i think a side but i never have pushed it to that im kind of a wimp lol
Very nice chips there, good to see! :)
You need a load meter. The first cut on the second was probably a 35% overload judging from the musical note of the gears. One musical half tone is about a 5% change in RPM: roughly no-load to full-load on the nameplate for an induction motor.
I loved to make chips back in the day but it was hard to max the envelope without popping a breaker or toasting the motor. Fortunately we had load meters on all the big machines so it was easy to dial it in to 95 to 105% full load motor Amps. Didn't have to figure musical pitches or watch for smoke.
I counted it a good day when the helper I shared with Schmidt at the next machine broke a running sweat keeping up with our chips.
Leonard Schmidt. Took a while to recall his first name. Good guy. Good worker.
G55 the 5555 to to
What about a keyway? Not needed for the application, or do you not have the tooling?
Awesome job as allways Adam !! That was some serious cutting on that big lathe. More and more guys start complaining about the travel videos, so maybe it would be a good idea to start off a second channel with travel and coocking vids so you get them of your back. Iff you planning on do so, let us know here on the 'main' channel coss i love those videos of you and Abby !! Cheers

I like that blue of the chips. I wish I could get a truck that color.
Get one of those chips on you and you can smell roasted machinist.
Why can’t I find a box of inserts for 5 bucks.
You like pushing those big machines,cool.
What magnetic dial indicator holder do you use?
Did you have a falling out with the original contractor?
MAN! That is what I call a coupling. Do you have a picture of what they mount to? We use a lot of helicoil brand inserts where I work. We only use that brand. Have tried others but the quality isn't the same. Ours aren't quite that big though. Mostly 4-40 6-40 and 10-32 . The small aluminum valve bodies we do take 4 each. We built a work station with a mechanical arm and an air powered insert tool. It makes the job so much faster. Used to do them all by hand.Tell the boss thanks for letting you film again. Tell him we aren't greedy but once in a while we like to see em!
185 M.P.H. and 400 miles wide. Hope you will be OK. Stay safe. You and Abby are always welcome here in Ohio ! Take care.
Hearing the Pacemaker lathe actually start to bog down and groan! That was absolutely INTENSE! O_O Sounds also like she gets taken care of like a fine racehorse for her age so that she's ready to come out at the bell and deliver the K.O. when these large-by-huge jobs come up that require lots of heavy hogging off! These couplings definitely tested her! Big, BIG thanks to your employer for letting you film this particular job!
Old school engineering, brilliant stuff. I did all of this as part of my Centre Lathe Turner apprenticeship at ICI Billingham 40yrs ago (1979 to 1984) believe it or not.
I'll be thinking of you when Hurricane Irma makes landfall on Florida this weekend, I hope that you, all your friends and family stay safe and that you do not have too much damage to you homes and businesses.
Stay safe Adam, you are one of the USA's National Treasures!
as a retired mold maker /toolmaker /pattern maker.I WANT TO THANK YOU, for all your interesting and informative information, on how you do things. You make it a joy to watch, and to know,there are still young people,who enjoy doing machine work, and do it right
Perfect chip form ... C's & G's & 6's & 9's !!! Good material for that kind of cutting ! Good job and GOOD video ! Thank you.
....and a cliff hanger...LOL
Hi Adam , why would anyone put a thumbs down , Best they show there work and lets all see ,,, Great stuff buddy ,,
From Australia to the USA ,,, Hoorah !
It feels like your working at night. Shop relatively deserted.
How do you tapered. Bores on coupling
How many abom torques does that lathe have?
I tell everybody dont dip you carbide in water
Adam Abby . I hope you are safe. David uk
Because Helicoil (R) is a registered trademark, you will come across taps that use the "STI" (screw thread insert) designation instead.
You need to try Time-Serts for common sizes. Far superior to Keen-Serts or Heli-Coils. More expensive initially and an extra step, but worth it.
The lathe has a fast brake for how big that Chuck is!
I've been playing around with carbide inserts for the first time on my little South Bend 9. I managed to get some pretty blue 9's and 6's after some playing with feeds and speeds! So satisfying.
Thanks for the video!
5 bucks. For all that. Incredible, steal of the decade! Always impressive how tough those inserts are.
