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
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=
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
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.
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
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.
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
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.
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.
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
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
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?
I really like it, but the center pin is hokey, with threads on a turning surface. Should have turned the center pin from scratch, so the nut would tighten at the proper time, I know the outside circumference is kept true, so probably doesn't matter really.
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?
Good video... nice mix of chat and speed-up/music. Too many good ideas on UA-cam presented with really bad videos... happy to see this isn't one of them.
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.
That will cut a nice convex radius. What if you put another insert step on opposite side for of the one you made and then just turn tool holder around for concave radius. Has anyone tried that?
Awesome video. I have been wanting to make one of these for my small lathe for quite some time. Yours is the most straightforward design that Ive seen. One question though. How did you affix it to the lathe carriage? I saw the four bolt holes. Do those line up with holes on your carriage?
Ahhh Ok then your carriage has T slots in it. Mine doesn't. It's ok though. I can use what you've done and just modify it. I won't need a base plate like yours. My carriage has a round boss on it already that sticks up like the one you machined into your round part I'll just mount right to that with a thrust bearing underneath or something along those lines. Thanks for the reply.
Just to Clarify I never saw You Smoke Anything I swear - Hahaha! It was just a general statement about turning Videos I've watched ! Was wondering if it was Dull cutting tools or something Else?
Only one question. what material is used to create this ball turner? I really like this project and i hope to see more of these in the future. Keep doing great things

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.

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
I like the way you have centered that plate in the chuck.

Dear David: Thank you for give me the idea. It is just what I need. Regards from Mexico.
Cleanest design I've seen yet
Excellent demo and very helpful to necessary "balls" in a model early locomotive I am making. Thanks
That's the best thing about ball-turner builds... using the ball turner to do it's own handle.
Liked and subscribed...BEAUTIFUL VIDEO. Quality of production up there with clickspring! Well done. Look forward to watching more of your videos.
glad i found this little gem. nicely done.
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.
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
Thank you for the time and effort to make this video, I appreciate it, I would like to build one for my machine,
Complimenti per il capolavoro che hai fatto.
Made one of those for myself. Works great

very nice elaborate yet simple, also one can add scale to measure radius
Thanks for the comment!
Excellent! Enjoyed that thanks😀. Another project to add to the ever growing list.... 😪
Thanks Shaun!
Shaun Whiteley good. Idas
Thank you David, I have been thinking of making one myself and this is just what I needed.
David you are genius 👍👍👍
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.
Very nice... Short and sweet!
Very nicely planned and completed.
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.
I thoroughly enjoyed watching your video.Highly educational.Thank you
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.

Tanks sir are u great man best teacher (Arshad Hussain)
Liked and Subscribed - nice video, thanks for sharing the plan source, great special effects with the CAD model. Well done!
Many thanks from Canada, I'll make me one, that's for sure...

Thanks for the comment, and good luck building your own version!
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.
Really nice build! I need a ball turning tool for my Schaublin.
Thanks for the comment!
Excellent work sir! I'll start making mine soon. Thanks for the video!
Thanks Stacy. good look with the build!
Good job. Thank you
Well thought out little project---good stuff
Thanks Ian
Good ideas abaut machining job.
Really nice job, and beautiful shots.
Subscribed obviously.
Thanks for subscribing!
So you had to make a part to finish itself. clever.
Excellent presentation - thanks- going to do it.
Muy buen y gracias por este video.desde chile
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.

Great job !!! Very good idea ...Thanks for the share ...
Brilliant work sir
Really cool tool - I love it!

That will cut a nice convex radius. What if you put another insert step on opposite side for of the one you made and then just turn tool holder around for concave radius. Has anyone tried that?
Ótimo trabalho amigo, parabens.
WOW... Thanks for sharing!!!!
Good idea. 🙏
Great job and video You got a new subscriber.
Thanks Tom
This was awesome!!!!
What if the tool holder would be a large ball resting on a magnetic cup?
Awesome video. I have been wanting to make one of these for my small lathe for quite some time. Yours is the most straightforward design that Ive seen. One question though. How did you affix it to the lathe carriage? I saw the four bolt holes. Do those line up with holes on your carriage?
Thanks joedell71 - that is correct. There are 'T' slots in the carriage that line up with the four bolt holes.
Ahhh Ok then your carriage has T slots in it. Mine doesn't. It's ok though. I can use what you've done and just modify it. I won't need a base plate like yours.

Good job.
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!
Nice work! Subscribed.
What is your method for initially setting a radius? Measure off lathe centerline to tool tip?
Meant to say, "measure off pivot point to tool tip"?
Great job
Can I ask why I see some tools smoke while cutting or facing and others are not
smoking at all? Oh! Great Video ! Thank You!
It probably just depends on how much cutting oil I was using at the time.
Just to Clarify I never saw You Smoke Anything I swear - Hahaha!
It was just a general statement about turning Videos I've watched !
Was wondering if it was Dull cutting tools or something Else?
Excellent job! I may borrow some of your ideas if you don't mind!
Thanks George. Good luck with your own builds.
Only one question. what material is used to create this ball turner? I really like this project and i hope to see more of these in the future. Keep doing great things
It's all mild steel - EN3A and EN1A
Thanks David
Gud job sir thanx for upload
👍👍👍👍👍👍👍👍👍
Awesome man
I cant get about the tightening at bolt of the center..
What is tip angle and material. ?
