LeBlond Lathe Cross-Feed Nut Part 1
ฝัง
- เผยแพร่เมื่อ 28 พ.ย. 2024
- We begin a viewer submitted project of machining a new cross-feed nut for a 15" Leblond lathe. The original part was broke, so I use a new piece of ductile iron and start machining away a new part.

Seeing the thumbs down 153 shows proof that if you were making GOLD BARS to give away, there would still be people giving thumbs down after they got the gold bar.
Keep up the great work you are doing , love your videos.
You are a master craftsman and natural teacher. Thank you for giving me something to watch on Saturday night and keeping me out of the bars.
+Courtney Harrington Your welcome!
I quit drinking some 18 months ago and between Adam and the Keith twins and Mr Pete and the gang I have never been so greatful for something to keep my mind busy. Learning by stealth ;)
@@Godshole not for nothing, but good for you.
Aaron, thanks for the comment. Another year on and still going strong. It's not much of a struggle to be honest but I don't miss the hangovers and chaos at all lol
@@Godshole I Forget the date ,but this is much better than my old life !
I am a gunsmith and naturally work with much smaller parts, but using the same techniques. To see you encountering some of the same issues I do from time to time (with scratch / deflection passes) helps me calm down some knowing what I am experiencing is somewhat normal. I appreciate what you do and how you demonstrate it. God bless.
We work with a lot of stacking tolerances, especially in mating a rifle action to a barrel, and the bolt to the receiver. The quality of our work is judged by how tight we can manage these clearances yet deliver a smooth, usable action under field conditions that can still put 5 shots in 0.250 or less at 100 yards. Some of my mentors can cut that figure in half.
Adam, I just want you to know how much I enjoy, appreciate and look forward to every one of your videos. I am a 75 year old DIY guy and find you illustrations, tips and suggestions far better than any book I have or have borrowed on shop methods.
Adam, you are doing a great job! Thank you!

Been a machinist for almost 40 years Abom... I respect that you left that measurement error in the edit. Amateurs never make mistakes: The real pros own em. Rock on brother!
ABOM, that radius cut and clean up was awesome.
Absolutely! So clean!
My dad was a machinist for posey Iron works in Lancaster PA for years ! He worked on things that weight tons!!they had a boat yard in Port deposit Maryland where they bilt liberty ships in ww2 ! They started making brick machines!! He retired in 63 !!!!!
Absolutely impeccable work on that radius cut
This is one of my favorite video series because I have an old LeBlond 15” lathe with I believe is the exact same part. So I hope mine never gets broken!
Why is watching this stuff so mesmerising ? I bet you find the same thing when working on lathes. Looks addictive !!!
I'm not a machinist, but I love watching you work. And your commentary is excellent. Feels like if I had the tools I could duplicate what you just did with out any problems.
I don't know but I enjoy watching threads being cut. You're a down to earth man and a good lathe Smith in my humble opinion. Unfortunately I have neither the space or a lathe to indulge my interest, but a guy can dream. Keep up the good work it is appreciated.
Wow... this is a guy who knows his stuff... quite impressive to see. I my self am a young mechanist who just started workin in the oil field, its just inspiring to see these videos because I learn a lot.
Thanks.
Been a IT server admin almost all my life, but these vids bring back fond memories of my days in high school machine shop.
Home after surgery, love these 4 vids. Lots of work and editing and very much appreciated. Glad I didn’t miss it.
Always have steered clear of the 4 Jaw but watching you use it makes it look completely necessary. Thanks So Much.

Top notch work ! Way back when I was at my first big machine shop an old timer showed me how to do threads 'upside down and backwards'. Put undercut at shoulder, start there and machine away from spindle. No problems about crashing at the end of cut.
I love watching people that have developed a great skill set like you Adam.
Thanks for sharing.
You whittled the new part from that block beautifully, the radius looks perfect.
The small stuff is just as much fun to watch as the big stuff. My indicator is showing that you are a true master! Keep em comin
Using one lathe to fix another is a noble deed.
its like 3d printing parts for your 3d printer
Hey Adam, Another great video. Anyway those marks on the raw stock are most likely draw marks. I am thinking this was produced with the continuous cast process. The material is melted in a big pot which has a section for mounting draw dies. The die block is equipped with a timed coolant system and draw bars. The material is allowed to cool in the die then pulled a short distance and the cooling starts again. The fingers/chuck of the puller leaves those marks as the material is somewhat soft at that point. The shorter the draw, the finer the grain usually. Years ago I worked at ITT Blackburn and this is how we made our silicon bronze for all sorts of bolts, connectors and all.
+Dennis Sampson That's how I figured it was made. The bronze stock looks the same way.
Hi Adam I know that this is one of your older SNS but I find. Your craftsmanship is. Like watching a old painting master. your every cut from the roughing to the very finest is like the rush strokes on a canvas you only have to look at a old painting to see what I. Mean watching you work. Is to me the same , just to watch you finishing a project with those very fine cuts is so mesmerising, please. Keep them coming ..I have never seen. You so happy my very best to both you and Abby,
Using the correct materials. Like your style Adam. Saw a guy making a fly wheel out of tool steel once (what was on the metal rack) the old engineers were very good at specifying the correct material's for the application
That material sure shows just how much better it is for turning compared with rough old basic CI... nice chips and finish.
I could smell the smoke in my memory !
Great job on the radius, precision eyeball at its finest.
Always a pleasure to watch the chips fly. Your information and craftsmanship and patient explanations always inform and entertain. I’d bet that piece broke under twist load while the lathe was braking to a stop with a dynamic heavy load in the chuck.
Back in the mid 1990's, I worked as a lathe operator for a couple of years at a shop that had a Lablond lathe that was on a Navy destroyer in WWll. It was a really neat lathe. They didn't really know how to properly operate it. I had to make a live center for the tail stock and upgrade the tool holder system so I could do the knurling that we needed. It was a quiet running, belt driven system. I think that it was around 12-14 ft. long.
Getting the material for a project is an art; I enjoy the actual making of it, too! Looking forward to part 2, Greg.
Very nice job Adam I really enjoy the way that you explain everything in detail and so precise about everything that really makes the video interesting.
I am one of the hobbyist. Thank you for all the details on this project. Learning a lot that I can use as I try to develop my skills on my Atlas lathe.
Hi mate. Good to see you making things in your own workshop again. That's where it's at.
THE MORE I WATCH, THE MORE I LEARN. THANK YOU FOR THE VIDS.
I could watch you work on the lathe for days
Adam: Really like watching your machining. You have been a GREAT help in knowing which turning tools and inserts to purchase. Have a WWII southbend lathe and just getting started getting it into proper shape after watching others such as yourself on TH-cam. Just purchased the turning tools and inserts led by your examples. Recommend more demos of the basics. Also recommend posting places to purchase the higher quality lathe cutting accessories. Purchased two of the cheaper SHARS turning tools that came with inserts similar to what you recommended. Can always purchase higher quality lathe tools in the future. Keep up the GOOD work.
Hello Adam, I love to see you smiling! It makes me feel good when you are smiling, I know you are happy with the work you have been doing.
All the best, Edgar
Abom79 - Love the video. I am a newbie on the lathe and appreciate the talking all the steps you are making! You are a very good teacher! I might learn a little from you! Keep the videos coming! I appreciate you sharing your time with us! Thank you!
I've been watching TH-cam craftmen videos for years, and I've never been impressed enough to comment. Until now.
Thanks Jeff
I was just writing a comment about that radius, and saw that some people have been faster then me...... Really nice job, man.....Congrats !
Adam, I am going to have get you a Round Tuit, they are so handy - guaranteed to assist in any project.
To use, just hang it in a prominent part of your workshop and every time you come in to the workshop you will see it and be prompted to do another job that you have put off/forgotten/misplaced - you know the drill. Love your videos, mate, you are a master, and I have learned heaps from you!
lol, machine shop Bob Ross "That's okay, it's your workpiece, you can make that any radius you want."
“Let’s just add a happy little chamfer over here”
Hi ABOM, I'm Brazilian and I'm a big fan of yours, Thanks for the techniques and videos, I've learned a lot with you
“Within .005 out of the gate”..... You rock, Abom!
giving you a sub for doing a viewers job in your own time. top bloke.
Sure like that lathe. It has some pretty awesome features and it is quiet. Love to hear metal being sheared by a sharp tool. Sweet radius.
I don't want to gush and Ooh and Ahh, but I will say that radius is second to none. It's what separates the Men from the Hobbyists...
+weshowe Go ahead, I won't tell anyone of you did.
Man,I love doing work that way. It's the only way,the right way. With good tools and know-how anything can be done right,right?
Am a tool maker but your work is off the hooks love it keep the good work going bro
I had to do this same job for my Boyl & Emmes Lathe . But I did it another way I bored and threaded the part and made an Alu-bronze bushing that threaded into the piece and had the same threads to the outside and it worked great Good job Adom
Great work, Adam! When you are done it will look like an OEM part! Thanks for the video and allowing us to watch over your shoulder.
Have a good one!
Dave
We have to love so many aspects of your work. I realize that also the quiteness of your lathe, its just so smooth. Thanks for another greate video and lecture.
WoW Adam great work on the radius cut. Gees I have so much to learn.
That radius was a thing of beauty. I always worry when you reach over the chuck like that to do some filing, that shirtsleeve has to be close. Be safe brother!
Glad to see a new project series! My favorite type of content from this channel
I enjoy watching your projects and your explanation of what the process is easy to understand thanks.
Great job. I had to make the same part for my LeBLOND when I bought it. I brazed it together and was able to use the machine to make a new one. I only had 4130 and no way to make the helix easily for oil inside so I bushed it with bronze.
I walked into a machine shop 42 years ago..text me if you have any questions..lol your stuff is gooood
Very nice! I like how you chose to radius the section at the bottom of the treads. Should be much stronger at that fail-point than the original piece.
I don't know the first thing about machining and such, but man I love your vids!!... Love the way you make things so clear, even for the dumb metro operator that I am!! Also sold to the family owned company thing... That's just super cool!... Thanks for sharing!! Keep it up!!
You asked what I thought.
I think you have considerable talent, and I think you should pass along your knowledge. Teach part time at a vo-tech.
your a better man than me adam. i would have had to make a test nut to fit the old part that's the difference between a pro and a hobbyist.nice work
it is so relaxing to watch you work.
i don't know why
If you will send the broken parts to me I believe I can repair it good as new. I was so impressed with your Lisle drill grinder I bought one on ebay. You will never know how much all your good work is appreciated.
I love the way ductile chips. Great video. Nice blend with that rad tool.
Just beautiful work Adam, those radius cuts were magic!
I just recently found out vermont gauge is about 20 mins from me, im in upstate ny on the canadian border, your guage pin set reminded me of that lol great vid as usual love going back and watching the oldies sometimes.
Easy job and nothing difficult here. This is what I would call a apprentice-job.
Thx for the video Adam hope all goes well today loading those drill presses.
14.45 'waddaya think?'.......i think its bloody lovely adam!!
I had some steel recently that is supposedly to be “construction steel”, but it does not rust. When I turning it, i broke two inserts and it would constantly smoke. Any idea what the problem could have been? They were offcuts from the end of a long bar and slightly deformed. I only worked with mild steel so far.
I can watch you work for hours! Nice job, nice video! Thanks!!
I had to pause the video and marvel at that radius cut for a few minutes...
I know precision is always very important, but an undercut and the outside dia of a thread don't need to be measured with a micrometer, a vernier will do as well. Sorry if i'm critical, but after being a lathe operator for 35 years, i think i can say this. This is so old fashioned, there are special thread micrometers to use, not needing loose parts to see where you got cutting.
When I got my first play there was 10 in Logan that I restored to like brand new I had a 3 jaw Chuck but it turned out to be so bad that they could really use it. The scroll was wore out and every time I tighten the Jaws it would be wildly different run out. So for the first six months that I had the machine I had to use 4 jaw chucks. And I am so glad now that I did that. Even when I did not have to dial it in tight I would anyway I pretended that it was absolutely critical that I get it perfect every time and doing that helped me a great deal. Now I can indicate my work with my eyes closed.
What a smooth operator.
that tool made a really nice radios at the base . mad skills dude !!!
I like this shop. Most interesting work this man does. Keep it up
I have a Sheldon 10" circa 1945 war production and my nut was broken when I got the machine. I was able to nurse it through machining a new one out of a trailer spindle stub that had burned up bearings.
im going to agree with ww0yrr 100 percent, everything you show us is outstanding and precise, i enjoy every video you create and look forward to all your future ones
Awesome Adam holds up this complicated little broken thing and says, “We’re gonna make a new one. Then, he drops down this huge bar of steel… The rest is history.
Looking Good Adam. Was good to here you say you forget something if you don't use it every day. I have the same problem. I'll have to think which way the travel is on my old LeBlond lathe. I really Enjoy and learn a lot from your channel. Thanks.
It will be easy to track the feed style for your machine if you create a label saying what does that machine do and affixing it to the compound.
I just watched Keith Fenner free hand a radius! Just playing with you, great work Adam.
Made a newb mistake tonight figured id post my shameful moment on here to see if anyone else has ever forgot there chuck key in the chuck and tunred the lathe on just to have your key thrown at your face... yes it happened haha love your videos. Be safe
nice work Adam can't wait to see the rest of it
Got buy me a bit height radius level,,,old eyes aren't what they use to be,,,another master piece as well, Bear
Beautiful work Adam. Thanks for sharing.
looks a lot better than the original
О о о ..!! НА Русском ! Спасибо !Учусь у Тебя Abom чистоте в мастерской !
..!! In Russian ! Thank you! Learn from You Abom cleanliness in the workshop
A local machinist friend of mine will thread with the cutter upside down, and reverse direction to keep from having to quickly stop machine in threading situations like this. Thoughts?
I've seen Keith Fenner do that on a number of occasions as well. He's got a ton of great videos also
Skilled hands, nice work Adam. Thanks for sharing
I think that relief for the thred cause that cracks you should make that tread without relief and that could be done anyway. Sorry if I bothering and thanks for sharing us your jobs.
mohammad Almrayati would be stronger if it was a radius undercut
Turning cast iron in a Monarch....somewhere, my grandfather is very happy :)
As a demo operation it was excellent. A lot of unnecessary precision went into the main shaft considering the original was a cast blank thread machined and faced. The whole operation should have been made welding the shaft to the face before all of that excessive machining.
It's going to interesting to see how you put the spiral oil groove on the ID. good stuff.
Pressing a button through it like rifling a barrel might work well. Alternatively if his lathe can do 3/4 TPI or less it might be a long enough spiral to use a boring bar and a threading insert.
Measuring over wires is a lost art. Nowadays they have thread pitch inserts for your micrometer. Which tells you exactly what the thread pitch diameter is. The old school way is to measure the mic over wires then you calculate what the thread pitch diameter is based on the wire diameter your using.
Ill contact you about building my crankshafts for 383 small block stroker Chevy Engines. Oh and not to mention performance suspension components lol. Im sure if I dod go the route and discuss that matter you'd knock them out the park. Ya sure do quality work my friend. I usually only mention this if its true. I just recently noticed your videos and knew right off ya been at it a minute or two. Keep it up bud! The industry needs folks like yourself!
Abom is a master but your better off getting your crankshaft custom ground. Grinding is the only way to go with a crankshaft.
Always amazed at how quiet your Monarch is Adam, wish my Atlas 12" was that quiet! Nice work on the part, lookin good!
+Makin Sumthin From Nuthin Yea it's an awesome lathe
I hear that's pretty common with Atlas lathes because of their straight-cut gears. Maybe it'd be a fun project to replace them with helical gears, if you have the equipment.
Nice work Adam ! Thank you.
Wonderful work Adam ! Really enjoyed man.. Thumbs up
Looking at the surface of the fracture, it looks very much like a stress fracture that has developed over a longer period of time, and not one that has been caused by overloading. This has some implications on the repair: stress fractures indicate an engineering or material flaw which should be corrected before building a part that will eventually fail again. In the case of the bushing, a ductile steel that is surface hardened only in some areas to improve wear resistance could be one approach. Also, smoother transitions between the various cross sections could help, as well as larger corner radiuses and smoothing-out of any tool marks...
That part may have see 30 + years use , maybe more than 1 shift a day at times , and was much larger grain cast .
