STILL the best machining content on KZfaq...

I'd go for a "Loosen Lows, Tighten Highs" T-shirt

Oh Adam..... That use of the Dead center for indicating the bronze center hole in the jaws.....that blew me away! I've never seen that done before..... But it's brilliant!!! 😉 And don't worry about sounding 'nasal' old buddy....... I think all of us would watch your videos even if you just used sign language -- they're that good!

This is Why i watch you Adam The skill and Professionalism and attention to detail cannot be taught from a book, It has to be hands on real work experience and you even admit when you fail... This is the definition of a master craftsman. God Bless you and Abbie. ❤🙏🏽👊🏽

Adam eye-balls it and says 'probably 10 thousandths' then measures it at 11 thousandths :)) a master at work

When you stated that you were excited about trying out that giant acme tap I could picture your flex arm going, "Oh Jesus!".

Using the dead center to indicate off of was one of the coolest indicating tricks I have seen you do. Thanks for showing that!

In my experience, making tons and tons of nuts for propellershafts, if you run the tap in dry, it'll fit the first time... Bronze doesn't want to be cut, so if you lube it, you're helping the material win and not the tool 😉 sharp tools and no lube is the way to go 👍

Love that Fex Arm. Done a fair amount of rigid tapping on my mill but that little bit of wiggle room and the hydro drive - seems like the bees knees.

"Loosen your lows, tighten your highs!" - a great title for a Country n' Western song.

29:00 I suspect that the power tap generated a good amount of heat expansion in the bronze and the tight spots on the lead screw occurred when the bronze cooled and shrank. Running the tap through a second time by hand on a room temperature part cleared out the few thousandths of shrinkage due to the part cooling.

Your video is always excellent. The scene of you loading the hydmech is great! Perfect lighting and focus. Sound is good, strong and clear. Never seen better on broadcast TV!

That dead center technique was really cool!

That pic sure as heck looks like the pipes I made in high school metal shop....41 years ago! :~)

Bronze always closes down after cutting, we used to allow +,002" on diameters to allow for this.

Wait until you start learning your CNC lathe..... And find out that, with power driven cross drills in a couple of the turret stations, you can make this entire part in one operation! Right now you're just curious about CNC..... But just wait and see what you can do -- Mr Manual Machinist, it will blow your mind. 🤗

I just love videos. I love watching them on Saturday afternoons just relaxing

Clever use of the centres for dialing that nut in. Respect!

Fun watching the new shop full then empty then full. :}

24:05 That sounds like when I try to open the bathroom door slowly at night. Thanks for the in depth walk through all of this. I know you're slowing yourself down by bringing us along, but it's appreciated. I have some brass to drill some holes in at home, and the reminder about brass wanting to grab probably saved me a nasty surprise with a drill press. I'll probably hand drill it to make sure it doesn't grab.

Your Dad's shop keeps providing! Nice video Adam.

Good stuff Adam! The lighting and video footage in the new shop looks amazing. :)

I am sure I echo all your followers in wishing you a very fast recovery. Get well soon.

GreT to see you working between the two shops. Great convenience. Good work on the bronze parts too.👍

Thanks for taking the time to show a few different set ups for indicating a part in the 4 jaw. I find that helpful.

cool trick indicating with the dead center!

Matches up with our original sample when it’s Just a block with a hole 🤣

I absolutely love to watch bronze or brass chips fly! Great video! Spring pass on the tap did the trick. I guess the whole world really is a spring.

it was very cool that you used a piece of material that your dad had handled for this project,excellent content as always.

Since I am new to machining, I really like videos like this where you show all the steps for indicating an irregular shaped piece in a 4-jaw chuck. Great video! Thank you!

Ya gotta love it when a plan comes together Maestro.🙃

That big acme tap is gonna be something else! Great to see you using your new machines to work on fixing the vintage one.

I know 'how' to operate a lathe and milling machine but I'm still little more than an amateur machinist even after almost 60 years a mechanic, I have to say I'm impressed with the way Adam used the dead center and live center to indicate the work! Very cool trick!

At 29:00 when you were manually tapping the hole my dog was really concerned with the squeaking. He must have thought something was in pain.

I love that technique for centering on a small hole. Definitely going to have to remember that one Thanks for the tip.

Nice work! If it was me I would cut those radius features first, then turn the remainder in the lathe with a 4 jaw chuck. Gives you more to grip for the milling operation.

I never saw that "dual center" centering trick before. Simple once you see it done, but still very slick. Nice! I was very surprised to see how much tweaking you had to do to indicate & center the part just flipping it around 180 degrees in the 4-jaw chuck after drilling the first through-hole. That's a mini-lesson right there. Oh yeah, and at long last, one of the charter members of Adam's vast tap handle collection finally makes an appearance. Bravo!

That's gonna be a beautiful piece when complete. Too bad that the 1st acme rod went out of whack. Everything is coming together Adam. Can't wait to see that BIG lathe actually make chips...Great Vids👏

I remember bronze "shrinking" after boring or tapping. I'm not surprised it was tight. Lovely job on that thread. Looking forward to seeing the rest come together. Thanks for another excellent video.

Squeal! LOL nice work Adam.

Great vid. Get well soon have a speedy recovery.

Nice, Fun & Interesting to see the new equipment and old pieces like the lathe tool holders working together.

Your hand tapping near the end got the dog's attention!

...nothing like sharp tools and new machinery! :D

I guess sometimes taps need a spring pass too :-) I expect the power tapping warmed up and expanded the bronze ever so slightly, making the threads on size for that temperature, but then when it cooled to natural temp it was slightly tight again. Edit: Sorry - looks like lots of others commented the exact same thing.

Sir, you are an artist.

I've had several sinus procedures done so I feel your pain.

To keep a twist drill from hogging in brass and bronze put a small flat on the cutting edge no larger than 1/32" parallel to the center line of the drill. This will make the cutting edge 0 degree rake and will stop the pulling.

Now that's a proper sized tap :)

That’s an ABOM size flex arm, so impressive how much torque that has!

Tapping bronze by hand would make a great coyote call 😬

I've learned a lot about machining from you and others on the you-of-tubes. Making things helps me deal Combat Related PTSD (Creative Therapy), and then I sell whatever I make on Etsy (as per my Better Half's "request" (LoL)) The only problem I have being Medically Retired from the work force and not having the funds to stock up on materials such as Brass to keep making things. An I'm sure there are tools that would help as well, but it is what it is. Please keep making great videos that I can learn from; and maybe I'll be able to practice what I'm learning one day.. Take Care and Stay Safe. "Go Hard... Be Humble..."

Que trabalho perfeito amigo Adam!!! Grande abraço daqui do Brasil a todos aí!!!

Great video, Adam. Your explanation and instruction are great. I enjoy seeing you indicate a part. The threading is a nice piece of work with that two-stage tap. I am looking forward to seeing some CNC action as well. Thanks for sharing,

Wow! The trolls are out in force.

Glad you are well Adam

24:49 a rare sight, a genuine Abom Smile

It took me three attempts to make a bronze lead screw nut for the cross slide of my Colchester Clausing 13" lathe. The third attempt was my forth time to ever cut threads. My very first time cutting threads was last month and they were external. I posted a seven part video series on the nut. The videos explain my struggle. Part 4 shows how I made the second nut work Part five shows how well a 6 TPI nut works on the 5 TPI lead screw. Part 6 shows how I discovered my mistake and Part 7 shows the result of making the correct thread pitch nut. I mentioned your channel as I was indicating the nut on the four jaw because your video on the subject is how I learned how to indicate on the 4 jaw. Thanks for sharing your knowledge.

Double Boost (John Mills) uses a trick for quickly getting it very close, before indicating with the dead centre. With the chuck jaws opened wide, he places the point of the tailstock mounted live centre in the drilled centre, pressing the workpiece against the face of the chuck, and brings the jaws in until they just touch the workpiece, leaving him close to centred.

Sorry your sniffer is stopped up! Glad you got it hoovered. Hope it comes back 100% right!

all the years I've been Machining, using that dead center and indicator to Center up that hole I've never seen before.. the way I was taught to do it on an offset hole like that in between Jaws was to just use a plain 60° dead center ( or whatever degree Center you have as long as they're mating ) open up the Jaws on the Chuck, use your tail stock and quill to pinpoint and press your work up against the back of the chuck then bring your jaws down to meet your work evenly ..once it's tight, remove your tail stock and dead center that should put you right on the money.. that's the way I was taught.. I wish I had a shop because I'd get up and go down into the shop and test it to see which one's better.. thanks for the tip Adam.. another useful tool for the Arsenal..

I avoided wanting this one because I thought it would be boring. But what I found out is, I was the most interesting video you have made and I want to see the rest of the project. Good job showing the indicator. Please show more content of indicating and getting parts straight.

Wow. this is wonderful. Talk about a "machinist's fit." I have watch Abom79 since SNS 2. This is the first one, that I remember, where Adam shows the indicating gauge up close at 22:50. Note that the needle is moving much less than one thousandth. Adam also guesses that he is out by 10 thousandth but it actually was 11 thousandth. This exemplifies why Adam is "Adam Booth Grand Master Machinist" and the rest of us are trying to be.

I have to say you make some excellent videos

Excellent work as always 👏👏

If this were food, I'd be drooling. 😎

I really like how you found center at 10:00, that's cool.

I think the sound of that hand tapping called all the dogs in my neighborhood!

thanks Adam

Get well soon! Big Guy !

awesome job Buddy

Don't be blaming Abbie I learn something new every time one of your vids airs Thanks A&A

The Precision Matthews machine looks exactly like the Colchester machines I used as a student. I guess you can’t improve on excellence. Our training workshop had machines made in the early 1970s. Stavros

Россия смотрит !!! Ваша работа завораживает !!! Мира и добра !

Man that tap used up some torque but the machine kept up no problem. Thats a lot of power concentrated in that little bitty hole.

saw the thumbnail and thought damn Abom is crankin out 90s weed pipes now?

Speedy recovery and thank to share it with us!! Amazing job as usual!

I love the sound of brass or bronze being turned on a lathe.

Muy buen trabajo maestro 👍

I was getting quite excited to view the cutting of lefthand thread on the lathe. The tap was an alternative method. Nice relaxed video.

Always learn something new regarding setting up and taking measurements. Thanks very much for sharing.

This could have been a good candidate for thread milling on your cnc mill

Would have loved to have seen how you counter weight the chuck in order to increase speed.

The sound of turning that tap by hand could be used to call coyotes

Learned something. Centering the square stocks center drill hole with a 4 jaw. Thanks!

Thanks for this video..verry good work

So long since I used inches and fractions. Thanks for sharing

my guess with the tapping is that: the powertapping with the flex arm causes allot of heat and makes the brass expand, due to friction of the relatively highspeed tapping with the constant rpm from the flexarm, making the 2nd pass necessary because of shrinkage after the first tapping.

Thanks for sharing buddy

Excellent teamwork as always Adam 🙂

Good work 👍

That was a fun one to watch Adam!

Ooo nice I need to make a new one as well thanks!!!

Thanks for sharing

Nice thank you👍🏻🇺🇸 know cool to see all other things going on , but nice to see some work getting done !

Great show Adam

Good job thanks for sharing

Cool saw

The up close tool shots were really cool to watch, and I don't think I have ever seen an acme tap quite like that, I have used them that only had the acme cutter before but never both

That flex arm is the coolest thing ever. I don't even do any machining and I want one
