That's not practical at all! How many time did you loosen the three screws to advance the cutter to work piece? 100 times maybe!! Because the center of rotation has to be fixed right under the work piece all the time.
@@thewarlordscalling6537 You are correct that the center of rotation moves when you advance the cross slide, but you are not correct that it matters. The swing of the tool covers 180 degrees of the ball's circumference, and you advance the tool (and its center point) until it is directly plumb with the rotational axis of the part. Other ball turner designs require that you start on center in both directions and advance just the cutting bit. This one operates more like a hand graver that is constrained in its movement. David didn't invent this, as he mentions, and he's only one of countless thousands of home shop machinists who have made one over the years. I assure you we aren't all so foolish as you believe. You simply didn't understand the way this is used differently from other designs (especially the variety which is based on a boring head mounted on the tool post).
It's almost painful to watch such a small lathe and machinery, but when aligning that rectangular stock... fuck me, that is one master trick. Perhaps the finished product is a masterpiece. I'll be machining a super huge one for my lathe. Thanks for sharing!!! You've earned my humble subscribe
Thumbs up hell no that deserves a lot more than just a thumbs up for your first time making one I thought it came out really professional looking that tool post would sale for over $ 80 easily
I worked in a production machine shope when I was young. Always wondered how a steel ball could be made! They only taught you what they wanted you to know there! Thank you for teaching me! =KL=
Hey this is so terrific i built one at the Rockinham mens shed. I turns out a really nice knob for a handle. first one turned out great. So good Terry and David will be making another one. I only took 3 weeks to make it approximately 6 hours
New here, nice to be on this channel because you are making some great machine tools. A ball turning tool post for the lathe is a great and very handy accessory to have.You did a great job thank you for sharing this even if it was done nearly the same as you share with a small deviation, Lance & Patrick.
That is amazing thanks for sharing, a great jig to get all around the ball aswel whereas I have seen some that are too big and would crash with the chuck if not careful
put a relief cut down side of tool holder or grub screws will burr it up never get it out make another tool holder with two carbide inserts facing both ways you can cut concave and convex
copied the idea and used it to make many bead roller dies. I did engrave a scale on the sliding tool post and mating base for quick setup for specific inside or outside radius. Thank you for posting.
VERY cool idea with the post/center out of the tail stock to center the 4-jaw. Why is it that when I see someone else come up with an awesome setup....It is always...GENIUS! why didn't I think of that?...Anyway, have fun, thanks, G.
fascinating video with many great practical tips (loved how you used the rod to center your square work piece..). I'm desperately looking for info as to how much clearance one should leave between moving parts.. can you point me to any material on this topic?
Well done, although can you possibly detail sizing and the reason you’ve scaled that way next build video? It would allow viewers to visualize actual finished dimensions much easier and determine whether or not to build one myself
How is this held in the cross slide. Could I add a part that would fit to a t-block. That way you could just advance the tool into the work and this would be faster, or is my thinking cloudy on this.
great video, I never had much use for the ball turning attachment until you said about the compression fittings. Thats something that would be invaluable with the projects I do, so a ball turner is now on the list of stuff to defenitely make, lol.
Thanks Virginia. The radius is limited by the distance between the bar stock and the bottom of the tool holder, which in turn is governed by the size of the lathe you make the tool for.
hey david, nice work, i really like it! theres one thing that might be unclear: when you make the tool holder, you take the height of the lathe center and mill it to that exact height... but, if you place your insert on top, it will be above the center? a solution would be to take 2 of the inserts you want to use and shim the tool holder in the toolpost up for marking the thing, that would give a dead on result when the insert is mounted?
Great video, you wouldn't have a list of material sizes for reference would you.. looks like something I will be building in the near future. I appreciate your efforts making this video, thank you.

LOL! He didn't have to adjust them at all. The base plate is bolted to the cross slide.
What an idiot ^^^ smh
Learn the basic principles of how the lathe works before inserting your uneducated analysis.
Looks like I'm the only who seeing the sense of your argument.f u feed using the crosslide then you lose your centre.u must advance the tool only

Great music choice. Calm, catchy, no lyrics.
Almost like a video where some industrial machine being advertised showing all of its functionality.

Dear David: Thank you for give me the idea. It is just what I need. Regards from Mexico.
Cleanest design I've seen yet
Hey this is so terrific i built one at the Rockinham mens shed. I turns out a really nice knob for a handle. first one turned out great. So good Terry and David will be making another one. I only took 3 weeks to make it approximately 6 hours
I like the way you have centered that plate in the chuck.
Thank you David, I have been thinking of making one myself and this is just what I needed.
Excellent demo and very helpful to necessary "balls" in a model early locomotive I am making. Thanks

I really like the design of this radius tool! I'm just stating a hobby shop in one of the bays in the garage of my new house.
I like it! It works on the K.I.S.S. method and any time you can use that method you're gonna be money ahead. Thanks, JD
glad i found this little gem. nicely done.
Very nicely planned and completed.
I thoroughly enjoyed watching your video.Highly educational.Thank you
That is amazing thanks for sharing, a great jig to get all around the ball aswel whereas I have seen some that are too big and would crash with the chuck if not careful
Liked and subscribed...BEAUTIFUL VIDEO. Quality of production up there with clickspring! Well done. Look forward to watching more of your videos.
Excellent presentation - thanks- going to do it.
Liked and Subscribed - nice video, thanks for sharing the plan source, great special effects with the CAD model. Well done!
Complimenti per il capolavoro che hai fatto.
Well done video, look forward to making something similar but for making custom dies for a bead roller!
put a relief cut down side of tool holder or grub screws will burr it up never get it out make another tool holder with two carbide inserts facing both ways you can cut concave and convex
Very nice... Short and sweet!

Excellent! Enjoyed that thanks😀. Another project to add to the ever growing list.... 😪
Thanks Shaun!

EXCELENTE TRABAJO SALUDOS DESDE MANIZALES CALDAS COLOMBIA
Excellent work sir! I'll start making mine soon. Thanks for the video!
Thanks Stacy. good look with the build!
Very nice - both the project and the video. Thanks.
Thanks for the comment. It's much appreciated!
That's the best thing about ball-turner builds... using the ball turner to do it's own handle.
Unblivabal sir thnqu so much.I am from India.and your work so good.
Brilliant work sir
Really cool tool - I love it!
Thank you for the time and effort to make this video, I appreciate it, I would like to build one for my machine,
David you are genius 👍👍👍
Ótimo trabalho amigo, parabens.
Great video. Inspirational.

Muy buen y gracias por este video.desde chile
very nice elaborate yet simple, also one can add scale to measure radius
Thanks for the comment!
Thanks for sharing your idea 👍👍👍
Well thought out little project---good stuff
Thanks Ian
Good job. Thank you

Great stuff!!!
sweet ,I think I'll make one......thank you for sharing.........
great job......subscribed..and liked....thanks for sharing,
Seen a different design of ball turning tool but I think this one is better as chatter is to be taken into account when turning tougher materials.
congrats!! good job!!
Great form turning
WOW... Thanks for sharing!!!!
Many thanks from Canada, I'll make me one, that's for sure...
Muchas gracias wro
This was awesome!!!!
Excrllent work thanks man!
Great job
Very nice idea
Great work
I like it.
Very nice job
muito bom .
Awesome man
Tanks sir are u great man best teacher (Arshad Hussain)
Gud job sir thanx for upload
Really nice build! I need a ball turning tool for my Schaublin.
Thanks for the comment!
thank you , what have you done in 0\38 munite
?
Good job.
Good idea. 🙏
Great job and video You got a new subscriber.
Thanks Tom
Since you seem to like to make your own tools you may want to look into tubalcain tap follower. Makes things way easier to tap.
Good ideas abaut machining job.

Thanks for the comment, and good luck building your own version!
muy bueno me suscribo a tu canal saludos desde argentina un abrazo grande
Excellent in its simplicity thank you for sharing this with us. Can this tool do larger simple curves?
Thanks Virginia. The radius is limited by the distance between the bar stock and the bottom of the tool holder, which in turn is governed by the size of the lathe you make the tool for.
What bearing did you use to tighten the M10? bolt to the rotating body?
Excelent 👍
Very good sir
very good
Very good ideas and How to make radius inside the job give some this type of ideas because I am also a lathe machine operator.
Nice
hey david, nice work, i really like it! theres one thing that might be unclear: when you make the tool holder, you take the height of the lathe center and mill it to that exact height... but, if you place your insert on top, it will be above the center? a solution would be to take 2 of the inserts you want to use and shim the tool holder in the toolpost up for marking the thing, that would give a dead on result when the insert is mounted?
Thanks Sharky. I milled off the thickness of the insert.
So you had to make a part to finish itself. clever.
DOPE!!!!
Grande😉
thanks u sir
Just watched all your videos and they’re great! Planning on releasing more soon? I see it’s been 5 months :(
Thanks Mikeyzs - new video now published!
very nice
Thanks!
thank you mate ...quite impressive though
Great video, you wouldn't have a list of material sizes for reference would you.. looks like something I will be building in the near future. I appreciate your efforts making this video, thank you.
Thanks Roger
Take a look at this link bedair.org/Ball/ball.html
Thank you for your video. I will definitely try it soon. More grease to your elbow.
awesome..will this fit on any lath
Thanks Norman. The principle will fit on just about any lathe, but it really needs to be scaled to suit.
Hi can you tell me where i can buy mini lathe like yours please
