I have been following you from Morocco for five years, and I went to the institute to study this profession and got a diploma that allows me to practice it. I am now working as a machinist and a lathe in a company in Morocco. I would like to thank you because you were the reason for me entering this field.
Good luck on your journey! I hope it brings you much prosperity
I've always admired his workmanship too. In a way he is like a friend.
RIGHT ON! Congratulations!
Abom have all the luck to have this all complete machinist tools...
That’s great to hear! The world needs quality machinists!
I wouldnt know anything about machining if it weren't for your videos, thank you for what you do. God bless.
Abom and a 4 jaw………….. goes together like eggs n bacon 👌🏻👌🏻
My grandfather worked at Cushman back in the day and I asked him the same question a long time ago and he told me that the holes in the back of the chucks face plate are for 1) balancing, bc the last you want is an unbalanced hunk of iron spinning on your lathe and for 2) they help to reduce the overall weight and 3) Harmonics.
It turned out great Adam! 👍👍
I'm glad you responded because I was going to. Weight, balance and harmonics are the reasons for the holes.
Great time to outfit that chuck for soft jaw covers. CEE just did a video on his method for getting tapped holes in hard jaws for that.
When I was in the Navy, "work it may, shine it must!", civilian life "work it must, shine perhaps". Grandmother said that cleanliness was next to godliness, looks very good!!!
Glorious, Adam. Absolutely glorious. Well done. Thanks for sharing. 😃
Hi Abby and Adam, I really like how you have sped up the video for the mundane long cleaning process , keep up the great job you guys.
That 4 jaw cleaned up nice and it looks good on the Pacemaker.
As a hobby machinist/landspeed racer, I appreciate your passion for the American traditions. Watched this resto series start to finish. Length is perfect for the task accomplished. Gonna have to have one of those t-shirts to wear at Bonneville this year. Thank You
Walter Schultz is the gentleman on Practical Machinist that makes the custom L series wrenches.
Those CRC products are the real hero of this story. Unbelievable how well those chemicals work together.
Anybody else ever put a scotch bright pad on a square pad or orbital sander. 😍😍Works wonders especially for those who have hand pains like me.
The 4-jaw chuck is really looking good on the lathe. Great work sir!
Watching you remove the chuck reminded me of something...
My Mom was a machinist at a company that made open pit mining cranes.
In the early 90s, the company was moving some of the machining equipment around on the shop floor to make room for new machines.
One large lathe they moved needed a chuck to be replaced (not sure why). She was tasked with helping in the swap of the chuck.
One day after she got home from work she told me that they had a little surprise at work.
When they removed the old chuck, on the inside wall of the lock nut, they found "JW - 1967" written in black marker.
She told me that "JW" was a coworker that used to work in the shop and had retired about 10 years earlier.
Moreover, JW had passed away a few weeks before they removed the chuck.
It was not clear how long the chuck had actually been on the machine, but apparently JW had touched that machine at least in 1967.
I was born in 1968... so that graffiti was likely older than I was. 😀
She said it was like JW was waving back at the shop from heaven.
What makes this more strange to me now... Mom passed away in 2018... almost like Mom is waving back at me. 🥲
I JUST LEARNED MY PACEMAKER HAS A BRAKE!!! Thanks Abom! I just saw you use it and couldn't believe it. I have only used lathes with a foot peddle bake and just assumed the pacemaker didn't have one.
can't wait to see some heavy metal machining again.
14:20 The holes also reduce inertia; less load on the lathe motor when getting up to speed, and less wear on the brake when stopping.
Adam, thanks for your videos. Between the music and your voice, it makes for a peaceful Saturday.
Adam, I have to say (after taking a break from your channel (after watching you from day one)) that you have come a long way. From your couple of minute videos from motion to this. Very impressed. As a kindred spirit for the best and tidy may I say your new shop looks amazing. I’m looking forward to reviewing the various aspects of the new machinery. Keith Fenner turned me on to these videos back in 2012. I believe you and Matt over on Diesel Creek have really evolved. The attention to detail, including your screw ups (as one should) editing, etc make the viewing worthwhile. Abby has been a great addition to your channel as well. Finally, I ALWAYS forget to put the damn gloves on. Always! Ugh. Thanks for your efforts. G
Just to hear you get excited with this big 4 jaw chuck on the lathe, priceless!
My girlfriend and i enjoyed it alot , well done ☆☆☆☆☆

It was kind of fun seeing you a bit out of your comfort zone installing the chuck on that L taper spindle nose, since I have seen you only working with Camlocks. (I don’t know about the Pacemaker at Motion Industries though)
For me it is the other way around, i have worked only with L-taper fittings and never ever with the Camlock system.
Therefore, and with all respect, I have 2 suggestions: there is no need to hammer the chuck loose from the cone. System is designed to turn the nut back against the bearing housing in order to push the chuck loose. In that position there are still a few threads engaged, so no fear that the chuck drops of the spindle on the bed.
The other one: when putting a chuck back on the cone and after tightening the nut by hand, release the tension from the hoist and then tighten the nut with the hook spanner. When the hook spanner is the original one, an extension is not necessary. The “Keith Fenner method” by jumping is the usual way to do the tigtening.
Again, no offence.
For the Colchester (Clausing) L1 taper is it said to give the wrench two sharp blows with a mallet. They also say not to use a cheater bar of any sort.
Been watching abom for number of yrs,its
Changed alot from slinging big chips and lots of machining ???
My grandfather was a tool and dye maker at the Ford trade school in Windsor Ontario. He made model A's and model T's. You and my grandfather would have got along well.
I sure appreciate your attention to detail and professionalism.
Thank you
Awesome!! Can’t wait to see chips flying off that baby!
your crane always seems to make jobs look easier, bet you are glade you have it
Nice to see that lathe spun up. Thanks for the video.
It's good to see that you enjoy CRC products as much as I do.
I can see the old machines pride starting to shine again Adam.
I have a 1927 P&W 13" Model M. Runs great. I'm 5 years younger than it, and wish I ran as well. . Love your channel and new shop.

Lightening it also reduces the moment of inertia, meaning it spins up and down more easily, saving wear and stress on the gear train and clutch.
Same reason "performance" cars are fitted with lightened flywheels, means less mass to spin for the engine and quicker acceleration?
@@ZanderKaneUK Exactly. Also why you sometimes see small-diameter multi-plate clutches in place of single large ones.
ONE OF THE BEST MACHINE SHOP VIDEOS OUT I LOVE HOW CLEAN EVERYTHING IS I HATE DIRTY EQUIPMENT AS WELL UR VIDEOS ALWAYS TURN OVER VERY WELL AND UR A VERY BRILLANT INSTRUCTOR AS WELL EXPLAIN EVERYTHING OUT WELL love watching ur videos from down under ossie AUSTRALIA
If each hole is 2.00", approx 2.500" deep, that's 7.856 In3 of steel per hole. Times 24 holes is 188.544 In3. Weight of steel is roughly (depending on grade/alloy) .2833 In3, so they removed 53.51lbs of steel. That's a lot of rotating mass saved.
Great job man, I like to restore old hand tools like hammers and axes sometimes my spare time, it's always awesome to see an old tool come back to life.
Thanks for that. Gives an idea of just how much steel comprises that big block of ironmongery. The momentum at max rpm is nothing to sneeze at.
your smirk after you got that chuck mounted.... excited to see some big jobs back in the shop! congrats, that chuck looks great
New shop looks great. I love hand files.
Well done job, nice! Thanks for documenting on film
One “Abom torque”….. your best line ever brother!!!
Thanks Adam. Mr. Booth you are indeed...... The Master!!!!!
G'day Adam. Lots of hard work cleaning the chuck assembly, which turned out really well. Also I like the way the job material gets indicated which you make look so easy. 😉 great video, waiting for the chips to fly.
Great job Adam. The chuck looks great. I wonder what the blank they start with weighs? You are correct, the holes are there to reduce the finished weight and also to balance the chuck. Some of those are just slightly deeper than others. Much the same way you drill out material on a flywheel to balance it. Looking forward to some production videos from the American Pacemaker.
That chuck cleaned up nicely.
First rate work as usual Adam. Watching the edges of the Chuck running true reminds me of my light-weight aluminum wheel head on my potter’s wheel! Best wishes to you and your sweetie!❤️
Lighting holes are used in so many products within machining parts, Your videos are so well explained on why you do what you are doing Thank you so much for sharing things you do as you move forward putting your new shop together
It's called "drilliun".
@@fernandofert9960 lol
Good job Adam, looks great. 😃
Oh wow old school lathe at the new shop, cool 🙂👍
Another job well done, thank you
That was satisfying to watch.
Take care of your machines and they will take care of you. Love the old school machines.
I feel kind of guilty for watching all of this job.
I’ve got a ton of work around here I need to get done.
When someone asks why I’m late getting things done I blame you.
I was a Millwright for years; I find it interesting how different skills have different names tools.
Well done...That's slicker than socks on a rooster!
Wow Adam and that 4 jaw looks better on the pacemaker than the 3 jaw
Thanks for a great video
Have you thought about drilling/tapping your chuck jaws so you can bolt on soft jaw plates? @CuttingEdgeEngineering does that and it makes a ton of sense.
Man it would be great to see and entire restoration on that machine. We had a few of those machines at the valve shop I used to work at in Mobile, one of them was off the USS Alabama. Always nice seeing new life breathed into old machines, they dont make them like they used too!
Yep, I miss restorations. It's the most interesting content for me. I was glued to the shaper restoration he did a few years ago.
Looks beautiful 🙌🏻🙌🏻
What a beast of a chuck
Really liked that silent intro. Another great video.
Congratulations ! You are really a perfect "desparate house wife" when you clean something ;-)) The next time you will come in Paris I give you the key of my appartement to clean it !!!
Big Big !!! Nice! Love it.
Congrats, Adam. She's a beauty.
Great video Adam. Saturday night fun
AMAZING!
3:02pm. Yes Sir! Evaporust & a parts washer…….. sure came in handy when restoring my 46 Gibson “A” Tractor 😃, I’m liking that speed em up feature on your video’s; especially during assembly. Now to figure that out in real time when I’m tuckered out and ain’t done for the day yet. I’m liking the tool you made to Turn the jaw screws quick also ! Well done Abom 👍😃😉💪
Very nice job Adam!!
Very satisfying.
100 percent cleaning and checking Great job.
Man, Adam, great to see you working on a 4-jaw again. So natural, must be the muscle memory!
That’s why I love my vfd on my koping first time I popped that L2 taper like you done after that I just used the jog feature on the vfd it works like a charm
The 4 Jaw looks great. Big lathe big chuck.
Outstanding job dude! From where that chuck started to what you ended up with (after a significant amount of effort on your part) is fantastic.
Really looking forward to gearbox and clutch "cleanup". Lets see it cut some chips! Love your work Abomb. It's inspiring.
yes ive got the same 6inc thread on my colchester lathe , as does ol keith fenner , break it lose then give it one more twick at the end to break the taper !!! good videos
I enjoy restoration videos
One tip for polishing and metal cleaning get a cheap vibrating palm sander and put a sheet of scotchbright in it add some oil and push it around a couple times and it's clean in seconds also works great on the welding table 👍👍👍
This is exciting bro! Big lathe, 4 jaw, abom. I am actually getting a bit of nostalgia from watching this video.
Looks Sounds Good - Thanks
I love this intro format
I remember when there was not a machine in your new shop.
Air-conditioning, Ac getting pulled so on and son.
You've come far Adam
kinda trippy seeing this in the new shop instead of the home shop like in the past.a little better lighting here lol
I wondered about the lightening holes in the rear of the chuck as well. I suspect some are used for balancing.
Like your new watch maker's lathe. Well, compared to your old day job. :)
So nice when a company steps up and makes the customer happy. And they didn't just drop off a battery, they sent a tech to do a proper job.
Great Video
beautiful hunk of machinery .
Good job👍
This was a pretty cool restoration. I really liked that you didn't have to seriously get at it to make it like new.
congratulations, I hope that your business goes well for you both. Uncle Terry
Thanks for sharing
Man what a beauty!
Make the CNC mill a vise=gripper type holder. Have your CNC mill take out the wipe-down rag and wipe down the machine every night.
Amazing that they left that chuck rusting on the floor while they used the 3-jaw. Lucky for you it was still around!
Your videos is so relaxing to watch. And all the love and effort you put in your machines and tools. Its just amazing. Nice work Adam!
Please don't be insulted, but I nap very well watching. I try to give a thumbs up right away so I don't forget
Pure Excellence!
I’m starting to think OCD is a must for a good machinist. Lol. Looks great Adam.
Adam, with the greatest respect mate...with you bouncing twice on the extension that will definitely be adequate Abom Torque 😄👌🏼
Amazing transformation... 🙂
Good stuff
Great stuff, looking forward to "abomb sized" chips.
Been a while, but love the new lease shop the way you have it laid out. I too need to make time to clean up all my chucks. Be happy when summer comes, tired of fighting with humidity here in TX. If you make the Fly Wheelers this year, have fun and hi to all the other creators from Bears Rod Shop 👍👍
That pacemaker sounds smooth
A clean chuck is a HAPPY CHUCK ! Apopsicle stick works wonders on threds and cracks
