Lathe Ball Turning Toolpost Build

[@ammartamimi9864]

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.

[@WyldStyl3]

LOL! He didn't have to adjust them at all. The base plate is bolted to the cross slide.

[@trevaFtrev]

What an idiot ^^^ smh

[@timsretired4835]

Learn the basic principles of how the lathe works before inserting your uneducated analysis.

[@thewarlordscalling6537]

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

[@intjonmiller]

@@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).

[@smartcrow7630]

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=

[@juanm6139]

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

[@DavidCambridge]

Thanks Juan!

[@theantichrist6524]

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

[@tonycstech]

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

[@theclothingcutternetworkda2840]

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

[@jdwisdom9433]

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

[@1DIYGuy]

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.

[@oscarmorales4182]

Dear David: Thank you for give me the idea. It is just what I need. Regards from Mexico.

[@stevebark4873]

Made one of those for myself. Works great

[@petersmith3703]

Excellent demo and very helpful to necessary "balls" in a model early locomotive I am making. Thanks

[@tszabon]

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

[@mannycalavera9181]

Cleanest design I've seen yet

[@427med]

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

[@chuirios365]

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.

[@KirksAuto]

Thank you for the time and effort to make this video, I appreciate it, I would like to build one for my machine,

[@thecorinthian4663]

Thank you David, I have been thinking of making one myself and this is just what I needed.

[@250-25x]

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.

[@DavidCambridge]

Thanks Gerry

Complimenti per il capolavoro che hai fatto.

[@ActiveAtom]

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.

[@meerajshree]

very nice elaborate yet simple, also one can add scale to measure radius

[@DavidCambridge]

Thanks for the comment!

[@markhobster8113]

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

[@munavversaiyed7354]

David you are genius 👍👍👍

[@edgeeffect]

That's the best thing about ball-turner builds... using the ball turner to do it's own handle.

[@omarnezali9415]

Good job. Thank you

[@mohabatkhanmalak1161]

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.

[@wayfastwhitie455]

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.

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.

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

[@girliedog]

Excellent in its simplicity thank you for sharing this with us. Can this tool do larger simple curves?

[@DavidCambridge]

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.

[@dennisrkb]

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?

[@MagnetOnlyMotors]

Great stuff!!!

[@shardakomalkar585]

Awesome man

[@SharkyMoto]

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?

[@DavidCambridge]

Thanks Sharky. I milled off the thickness of the insert.

[@YOURFISHINGCHANNEL]

very good

[@PaulHigginbothamSr]

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.

[@DavidCambridge]

Thanks Paul

[@josetadeumantovani5706]

congrats!! good job!!

[@tomkovacic2736]

Great job and video You got a new subscriber.

[@DavidCambridge]

Thanks Tom

[@jimmurphy3868]

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?

[@marciocunha1579]

muito bom .

[@normoloid]

What if the tool holder would be a large ball resting on a magnetic cup?

[@jimturner9697]

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.

[@stivenjaramilloalvarez136]

very nice

[@DavidCambridge]

Thanks!

[@mohdshanu3272]

Nice

[@npalen]

What is your method for initially setting a radius? Measure off lathe centerline to tool tip?

[@npalen]

Meant to say, "measure off pivot point to tool tip"?
