LeBlond Lathe Cross-Feed Nut Part 1 

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.

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.

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.

Absolutely impeccable work on that radius cut

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!

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!

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.

Why is watching this stuff so mesmerising ? I bet you find the same thing when working on lathes. Looks addictive !!!

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 !!!!!

Been a IT server admin almost all my life, but these vids bring back fond memories of my days in high school machine shop.

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.

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.

Using one lathe to fix another is a noble deed.

You whittled the new part from that block beautifully, the radius looks perfect.

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.

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. John in Salem, OR

I love watching people that have developed a great skill set like you Adam. Thanks for sharing.

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.

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,

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

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.

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.

Hi mate. Good to see you making things in your own workshop again. That's where it's at.

I could watch you work on the lathe for days

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.

Getting the material for a project is an art; I enjoy the actual making of it, too! Looking forward to part 2, Greg.

THE MORE I WATCH, THE MORE I LEARN. THANK YOU FOR THE VIDS.

What a smooth operator.

That material sure shows just how much better it is for turning compared with rough old basic CI... nice chips and finish.

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.

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!

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 RU-vid. 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.

I was just writing a comment about that radius, and saw that some people have been faster then me...... Really nice job, man.....Congrats !

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

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

WoW Adam great work on the radius cut. Gees I have so much to learn.

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.

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.

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...

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.

Am a tool maker but your work is off the hooks love it keep the good work going bro

“Within .005 out of the gate”..... You rock, Abom!

giving you a sub for doing a viewers job in your own time. top bloke.

I enjoy watching your projects and your explanation of what the process is easy to understand thanks.

I've been watching RU-vid craftmen videos for years, and I've never been impressed enough to comment. Until now.

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.

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?

it is so relaxing to watch you work. i don't know why

Easy job and nothing difficult here. This is what I would call a apprentice-job.

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!!

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

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

I had to pause the video and marvel at that radius cut for a few minutes...

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.

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

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!

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!

I love the way ductile chips. Great video. Nice blend with that rad tool.

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 walked into a machine shop 42 years ago..text me if you have any questions..lol your stuff is gooood

nice work Adam can't wait to see the rest of it

I can watch you work for hours! Nice job, nice video! Thanks!!

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.

Thx for the video Adam hope all goes well today loading those drill presses.

lol, machine shop Bob Ross "That's okay, it's your workpiece, you can make that any radius you want."

Just beautiful work Adam, those radius cuts were magic!

that tool made a really nice radios at the base . mad skills dude !!!

Glad to see a new project series! My favorite type of content from this channel

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.

Nice work Adam ! Thank you.

I like this shop. Most interesting work this man does. Keep it up

14.45 'waddaya think?'.......i think its bloody lovely adam!!

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.

Beautiful work Adam. Thanks for sharing.

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 just watched Keith Fenner free hand a radius! Just playing with you, great work Adam.

Beautiful radius cut

Very good workmanship mate looks great 👍

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.

Got buy me a bit height radius level,,,old eyes aren't what they use to be,,,another master piece as well, Bear

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

That stuff machines real nice for sure !

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.

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.

Skilled hands, nice work Adam. Thanks for sharing

Great job and awesome presentation!

Always amazed at how quiet your Monarch is Adam, wish my Atlas 12" was that quiet! Nice work on the part, lookin good!

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!

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.

Nice video. Reminds me of some parts we used to make in a CNC. Kevlar reinforced internal guards on that machine to prevent anything catastrophic. Those parts spun at 5000rpm, .300Doc, with a glowing red ceramic insert. Was quite awesome, cast iron, high production, but awesome nonetheless. Wish I could find video, must have lost it somewhere along the way. Love your vids man, keep Rockin'!

Beauty! Great discussion/demonstration ......are you going to machine the spiral oil groove on the ID?

great video I just love the sound of the monarch

Very Nice Job so far Adam, Regards Frank

Wonderful work Adam ! Really enjoyed man.. Thumbs up

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!

Nice work Adam
