If someone had asked me to buy a left-hand ACME tap before I’d watched this video I’d have thought they were pulling my chain! You learn something new every day.
They're not cheap. Not as pricey as the two start!
I found my 14th edition Machinery Handbook in an old building I was cleaning out. Talk about a score.
You Lucky Son of a B.... ;-) That is awesome! :-)
That was an Awesome Score!! Lots of info.
Nice find!
The videos from your Motion days are interesting but a man can only spend so much time watching you whittle pump shafts. Now that you are doing projects for views things are becoming veeeeery interesting Colonel Hogan.
Thanks for mentioning that. I hope others can understand that as well. While the heavy machining was awesome, it was repetitive and I had been showing that for over 5 years. In time as I acquire more machine machines I'll be able to show my own heavy work in my shop. It's all part of an adventure!
I Know Nothing!! ;-) Rouse, Rouse!!
I love it when brass and bronze are turned on a lathe, such beautiful yellow and red materials
A shame the chips are like little needles that work their way into everything... especially your skin... 🙄😭
@@peterfitzpatrick7032 ...that's a POSSIBILITY- but it's not a CERTAINTY!!
Shame about all the metal splinters you get for the next week!
Aren't they wonderful Richard? I love those metals, too. Soft (compared to steel) but indispensable.
@@peterfitzpatrick7032 Coveralls. There. Problem solved. Right Dale? :-)
there are few channels on youtube that inspire me to get out in the shop and build something like yours does. because of you i now know how to use a lathe, and bought a 1953 Wells Index mill i'm learning to use. I can now build/repair just about anything i want. thanks Adam, keep up the great work.
Anybody else find this relaxing? I'm sitting here with a cup of coffee my Sunday morning watching this video saying to myself life is good
Interesting explanation of why you didn't use a pilot drill in brass. Never heard that before.
I learned that today also.
Having just spent a week in the hospital following surgery I want to express my gratitude for your videos, again and again, Adam. I have watched them all, but they are so packed with information and interesting observations that watching them a second time is no less rewarding. I would have gone even more crazy than I am in the hospital if I had not had your videos to keep me intellectually engaged and fascinated. Best wishes and thanks very much!
That chuck is a thing of beauty.
I'd rather listen to that squeaking tap than most modern music. Beautiful Work both Visually and Audibly! Thanks Dude!
I love watching brass and bronze machining, it looks like it cuts effortlessly, your macro close up shots are amazing.
I love watching brass being machined. Brass like this has a beautiful color to it and being a softer metal, it's simply fun to watch it being formed.
Hey Adam, you may want to try some of the shooting earmuffs. The electronic ones are pretty nice for stuff where there is noise at some points. I was using some to cut down some brass and when the machine is shut off I can hear just fine but when the noise level goes up they cut out the sound and protect your hearing. The more expensive ones are nicer and you can get the ones that actually work as a bluetooth headset as well and go in the ear like some earplugs. Will be nice if you want to listen to something while you work but also have the ability to hear things going on around you at times. Can pick up a cheap pair at some of the big department stores or sporting good stores to test out and see if it's something you like. I enjoy them as when you want to hold a conversation you don't have to pull plugs out but when the noise level goes up you don't have to think about putting them in.
I had to check my subscriptions all the brass chips I thought Clickspring had a new video out.🤣 some nice machining today 👍👍
@@jimmer411 LOL your right on that Clickspring has better content IMHO. 🤣
I think your camera work in this video is better than usual but I can't put my finger on why exactly
It's because he changed the music. :^)
When I saw the title I thought maybe I would be seeing a process that I used to perform. As a power plant machinist we would quite often be required to thread valve motor operator stem bushings. The bushings were supplied by the motor operator manufacturer as a blank since they didn’t know what valve it was to be used for. Most if not all large process valves use a double lead left hand acme thread for the stem for speed. Being a power plant, all machining was manual since CNC was not cost justified for one off work. We used to single point double lead left hand internal acme threads quite often. Usually around 1-1/2” dia with a pitch of either 4 or 6. An extremely tedious process to say the least.
Nice work Adam. Looks like your shop is working out great for your self employment. I am very happy for you and Abby.
Thank you, everything has been doing good.
Hello Adam, I teach a machining course to second year mechanical engineering students at Ohio State University, but this semester of course we had to call things off due to the virus. Just wanted to tell you that I came across your videos while looking for material to show my students since they can't get back in the shop this term. Great stuff you're doing here. I'm sure my kids will get a lot out of it. Many thanks!!
Very cool! I’m always honored to hear that some of my video are helping those in the educational field. Are there any specific subjects that would help out or they would like to see?
I obsess over countersinks too. I've started making my parts with a short counterbore on top of the countersink so the head is flush but the hole isn't bigger than the head diameter. Easy on a CNC, but you can do it on a manual if you use a countersinking bit the same size (plus a few thou for clearance) as the screw head.
I been watching your channel for 3 years so proud that your back in booth's machine shop your family built a name keep it go thks for your time showing us the projects
nice job, still doing a full watch through on your videos, on sns 57 now, decided to skip ahead to watch the two new ones u put up today to see how things have changed. keep it up sir. hope yall stay dry from this storm raining on us over here on the mississippi coast
Manually tapping acme threads really makes me appreciate my Haas SL30. Great work as always.
Thanks Adam I always learn from your video's. I Appreciate it !!!
Adam, you are a natural man working with metal. Been watching for a year and a half an have never been disappointed. I admire your interaction with your family and do enjoy seeing you celebrate family time with food and drink. I am a 71-year-old man and envious of your talent. Cannot get enough. Question: Please share the older intro music with us. I would like to know who the artist is. Thanks, Chuck.
Talk about excellent filmwork. Geez. Can't get better than this!
Planning and effort in the production of this one is one of your best yet. I know close ups are a pain but it really adds a lot...Dave
Good to see even the best use Polish products :) best greetings frm Poland, amazing videos!
I love turning free machining brass and bronze. It's the best and looks great. That's a nice piece he sent!
Always good to come here and learn something.
"He needs more precision on his wood lathe".... you are so funny!
That was funny.
I love that indicator in the mill, better than a fidget spinner!
I tap a 1/4 2 start acme in 360 brass. It screams and is very unnerving although being careful has made the tap last!
God, we have an order for 1000 1/4-16 4 start acme threads in 360 brass. Fucking nightmare.
That internal Acme thread looks beautiful! Real nice piece there Adam, good job.
I just made my first acme nut this week. A 2-2 LH two start stub acme.
General rule of thumb for step drilling is: For "Hard" materials, your lead drill should be about 3/4 or larger than the diameter of your finish drill size. For "Soft" materials, your lead drill should be about 1/4 or less the diameter of your finish drill. Do this to prevent the drill from "grabbing" and pulling the part out of the chuck, or the drill out of the tailstock.
For example, when drilling steel, if you want a finish hole of 1", use a starter (or lead) drill of no less than a 3/4" diameter (or larger) and finish with the 1" diameter drill.
When drilling brass, if your finish hole is 1", start with a lead drill of 1/4" (or less) and finish with the 1" drill. This works everytime.
That was the easiest internal acme thread cutting I ever watched. However, it did sound like you were out bird hunting for constipated ducks!
Quack, Quack! I know. Gotta love it! Those (actual) bird calls are interesting designs. I suppose you could drag the lathe into a blind but...nah, that would be impractical. But you would kill two birds with one stone. I know... ;-)
That boring bar is exactly what I need to make the socket rings I make! (I asked you about them a while ago) I am getting my ankle replaced next week and will be laid up for 6-9 months, so I will look into getting one.
Nice job Adam...thats what seperates the masters from Abom79.
Only a matter of time before Adam starts saying "focus you f***!!"
cozmium ave.
I'd pay to hear him say that😂
We really do need an "Abom After Dark" channel.
Might find that over on the Patreon feed...LOL
You're damn right! haha
Good tip for two lathes with shared tools: Machine the top slide mounting surface under the toolpost (or make shims) to match the heights for the tools. Did that at work for two lathes as they had a tiny 0.5 mm dfference in height and it was always fiddling with the height adjustments when borrowing tools. No more of that :)
Great results, Adam. Press on!
I love your detail and care you put into your machine. Your very clear in your explanations. lot of fun watching you Adam
Don't half ass it. Higbee the thread lead-in on the back side of the nut. Haha. Jk. You're the man Adam.
"I got to grab my earplugs"
Haha me too. Watching this on the Hi-Fi.
If only Adam had a volume control on his lathe. ;-)
As a professional armchair machinist, my finger is always on the volume button.😂
Good for you. Spoken like someone who wants to make it to retirement with his hearing intact for the most part, and all of his appendages still working. Very professional. Good safety practices even in a single person shop.
I this very same job for lathe we have. I started with a piece of bearing bronze and turned the od to an interference fit with the quill. Made the nut about 3" long and pressed it in. No need for hardware.
Really liked this video Adam, great "flow" to it. Thanks.
Super job ....vous êtes très méticuleux et d'une incroyable patience
I think you're shop chair looks a little worn, maybe it's time to put a new seat on it, I know you have a new one laying around somewhere😉
Still enjoy your videos very much and learn a lot, I can make threads on my lathe now. I had a little tough time but I'm back again, I have gotten back to my old trade as electrician and found a good job.
Hi from Henning 😊
I’ve got that awesome seat cushion put up in a safe place and safe. It’ll get mounted one day and the frame fixed up properly. 👍🏻
A very big LIKE to your efforts for this video
That alligator wrench is cool
Wow! You can really see that tap twist on itself as you turn it. Great camera work.
Greetings from India. Please do a bit video about the Starret Anvil Micrometer used in this video. Tons of thanks for the in-depth explained machining techniques . Thanks !
Nice work... for those that of us who do not have a tool sharing relationship with Keith Rucker... McMaster Carr sells pre-tapped nuts in a large variety of sizes, left and right hand. I have bought round nuts from them and machined them to suit.Adam, out of all of the major TH-cam machinists... I would think that you would win the "guy with the most tooling" award. Too bad Ontario is a long way from Florida! :)
This is great close camera work, Adam. Well done.
Beautiful work Adam. For the absolute best finish without chatter on countersinks do the final cut while the spindle is stopping (coasting down). Chatter cannot occur while speed is changing. Old machinist trick taught to myself by me...(:-))
Thank you for showing @ 28:36 ! I wondered how you were going to figure that.
y using the wrench like that to tread puts pressure on the tap itself, especially on longer ones it will simple bent them has they are treading, i usually also every 2 3 turns i turn just a bit backwards to help realease some chip and reduce the pressure on the tap. Really nice professional job has always pleasure to see
Dang, I learn more in 10 minutes watching you than I do in months watching other guys videos.
One of the scariest jobs I ever did was tapping Acme threads in some stainless steel parts. It was a production job and we had quite a few to get tapped. If I remember correctly we were using a 3 step tap. I was sweating bullets getting those things tapped. We made it but just barely. The taps were missing a few teeth by the time the job was done.
I didnt even know you could get acme taps!
Always enjoy watching and I also like it when you tell us how you plan to do the work. Looking forward for more, thanks. :-)
I like the camera angle at 8:00
The brass is so beautiful.
Thank you Adam always enjoy your videos from South Africa
Absolutely Gorgeous.
Your becoming very good at these educational videos. Well done
My third year apprentice exam piece had a 1 inch whitworth thread and nut, a 2 inch acme thread and nut ,and a
1 and half inch spline , all on the one piece. A pulley had to fit on the spline. Oh and I have the twentieth edition of the machineries handbook.😁
I love seeing the parts "coming to life" as you make them but they're even more exciting in person and work flawlessly. I just feel bad all your hard work is hidden inside the tailstock!
Oh, to have such cool tooling and machines!
Enjoyed that.
As far as that acme tap goes, I would just set the chuck on the table of my tapping drill press and gun it at the lowest speed while blasting air and coolant all over the place...If I was to break that tap and Keith is coming after me for it, I would at least rather go out in style!
PS: I am willing to bet that with a proper tap holder, rigidly held part and some flood coolant, it's way safer and gives longer tool life than wrenching it's tears out as long as the motor has enough meat or a low enough gear, as the smooth action of a high quality tapping machine allows tapping things that you would otherwise mangle by hand, such as small interrupted threads at an angle etc.
Hey Adam, next time you're doing a substantial amount of work with brass/bronze/aluminum bronze/etc... try using a boring bar and run the lathe in reverse... blow all those nasty chips away from you. An old time machinist showed me that trick for making bushings. Nice job on the video, cant wait for the lead screw.
Remember the argument you had with your math teachers; "I'm never going to use this in real life. Why do I have to learn it?" Thank you Abom for demonstrating why Calculus, Trigonometry, Geometry, and Algebra are important.
Your comment about problems with doing the tap manually makes sense.
Kinda neat how the chuck works as a slack then spins off the tap a small angle, suppose not worth paying for a lathe 3x the size you need for but it definitely helps out and absorbs inertial moment.
Good idea on the gloves the boss lady doesn't want to be smelling the tap magic in the salad dressing.lol
I really enjoy the new machining videos. Some really interesting projects. I will admit though I miss the occasional heavy lathe video.
Absolutely love the real-up-close shots of the work! :)
360 has a sound that identifies it in an instant.
As does the cinnamonish smell of the TapMagic Alumnum. It does have something about it that triggers the spidey-sense that it might not be all that good to be in contact with or breathing too long. To further add to the concern is the lack of ingredient info on the can. Been wondering what's in it for 30+ years. Still using it though.
Nice piece! Looking forward to the rest.
Well done old man. Sounds like life is treating you well...
I loved the close up shots and would like to see more.
Adam, really enjoyed your video sure would like see your project finished and installed thanks for sharing.!.!.!.
I'm a little surprised you did the bore in a second op. That 6 jaw chuck must be very repeatable.
That's good info on the wrench and power tapping. I had a 1"-40 thread for a lathe tool height gauge that went cattywampus power tapping it with a wrench just as you describe. When I followed up on the second try, I just turned the tap by hand and it came out much better.
Great piece.
The tapping squawking was freaking out my cat.
Easy machining stock is always nice. Great looking nut.
I went into a trance watching this and went to blow the chips of the boar bit 😂 love the vids! They are so immersive
5:48 Whenever I see brass turned on a lathe, one thing springs to mind: Clickspring!
Hey Adam, thanks for the video as always. Not sure how often you find yourself using tools between your two lathes, but back when I had two machines with different center heights, I machined a spacer to raise the lower toolpost up. Initially just superglued a block to the top where the height adjustment nut contacted. Kept me from adjusting tool heights constantly, could save you a little time! All the best, -Jerry
Nicely done!
Thanks for the video. 👍
Excellent selection of intro music I've learned a lot from you and continue to learn thank you for your videos
I know practically nothing about machine other than watching, leaving the lathe head unlocked helped prevent stripping the threads and/or snapping the tap?
You can't lock the lathe spindle. You put it in low gear to provide resistance. If you apply more torque it will turn. Big tap with chunky threads needs a lot of torque to turn.
When I was a kid many, many years ago, I used the father's (a toolmaker and engineer) tools when I had a fairly simple job to do. I was once about to drill a hole in steel when he took the drill bit bit from me, and handed me another saying "Use this drill bit, the one you have has been backed off for brass". He said you sharpen a drill bit at a different angle to normal for brass. Could you confirm this (or refute it) and tell me what angle should be used on a drill bit reserved for brass? Love your videos. Keep up the good work.
I'm not Adam, but you're correct. You don't want a sharp edge as they bite into Brass and try to pull the bit into the work. Simplest way is just to grind the back clearance off the bit. It's even more important on a mill or drill press as you hand control the quill and the bit can easily bite. If you are silly enough to hand hold the brass workpiece it will spin and cut you, you're not going to be able to hold it unless it's a very small drill bit.
Hi Uncle Phil. Thank you for your reply. I wasn't sure just what my father meant by 'backing off'the drill bit, and I have left my run too late to ask him now. Cheers buddy.
If it quacks like a duck, you might be hand tapping a Acme Thread.
Cheers, Gary
It woke up my dogs and they had to check out what animal made the noise. 😆
Adam I have worked in Brass. ... You Sir make mine look .....amateur. thank you
always enjoy
Love those close up video shots....👌
Adam love your videos and I know this not your design but here is some food for thought, that bearing is made for a radial load or centrifugal forces not an axial load. The design should incorporate a thrust bearing for this type of axial load.....
Nice content, can't wait to see more of the same.
I ALWAYS had trouble with the counter bores. It is such a delicate balance. I was doing them on a drill press, and probably got impatient. And I found out about having the wrong angle tool. Ugh! Childhood.
the video quality on this is great did you get a new camera the focusing showed so much detail not only with the acme threads but the surroundings as well. beautiful job thank you!!
That tap could have a good second career as door squeak sound double in a cheesy horror movie :)
