Hi Tony,
Could you possibly have me confused with someone else? I have not had chatter issues with my over the top ball turning attachment. I think it was the original poster who was having problems.

tThanks for posting that link https://get.google.com/albumarchive/...99061223276003 there is some real interesting stuff there. I think we are of a similar age as I remember some of those press pages from my early twenties onwards, my favorite mag was Motorcycle Sport (which I still have a stack of) as they would contain more in depth technical articles. I have found alternative designs fascinating but lacked the technical ability to anything more than observe.
It looks like I have accidentally deleted video files from my Dropbox, and so the video link for this post was broken.
I am working through putting these videos up on Youtube where they should be safe. Here is the link for this one.

I use a 2” Criterion boring head for up and over ball turning. Micrometer adjustment is indispensable when turning ball precision ball shapes. I have adjustable stops on both ends of travel.
He's using the compound slide pivot, if I'm understanding correctly. Then all he needs is a block that puts the cutter on center. Swivels the compound, and that moves the tool in the arc necessary to cut the ball.
Though I'm with you on wanting more pictures and a video or two... ;)

Though just having resolved the dates, I'm way late to the party, and Tony already posted the video you asked for. Too much blood in my caffeine system. ;)
I no longer have the ability to use this ball turner, since I electrocuted my lathe I have no need for taper or ball mechanical turning devices. My electronic control and software takes care of it all for me. What am I talking about? Look here

So I now use a solid toolpost support without a compound.

Now you're taking all the fun out of it! ;) I have John Dammyer's Electronic Lead Screw for the import 3-in-1 machine my brother bought for me. If I ever get all the varnish that used to be grease out of it. :( I didn't take the CNC portion of the class, what would be a natural progression for someone intending to be a real machinist. I just wanted to be be able to use my little Chinese mini-lathe from Harbor Freight. And then the Atlas TH42 I bought almost a year after I started the class...
Hi! My name is Bill, and I'm a toolahaulic!
Did I mention that I now have 5 lathes, 4 milling machines, down to 2 drill presses, and a metal shaper? 3 or 4 bandsaws, a chop saw, 3 bench grinders, four angle grinders... Man, I've got it BAD!
No you are wrong, it doesn't take the fun out of it. It is much more fun using the lathe now.
Yes you do have it bad, I wish that I had the space. I am tool deprived.
1 lathe, 1 CNC mill, 2 normal drill presses, 1 sensitive drill press, 1 T&C grinder, 2 bandsaws, 1 shock dyno, 1 flow bench, 1 watercooled eddy current dyno awaiting installation, 1 linisher, much of it homemade.
Different strokes, as they say. I've got too much ADD to be all that interested in learning to program a computer. I did programming for fun for a few years when I was a young guy. Put myself online with a 300baud modem and a Heathkit H89 my FIL built using a TurboPascal program I hacked together out of someone else's material. I would not have been able to write one from scratch, as my brain doesn't work that way. Tried several times, in fact, never could get it off the ground. I was able to learn manual machining. For a student, I was even getting pretty good at it. I will need a lot more experience to get any better, though. Honest truth is that I really started way too late. And I don't think I have enough time (even if I live another 30 or 40 years) to really learn to program G-Code. Might, maybe, be able to learn how to do 3d design. Someday. ;) NO BETS THOUGH!
CNC or something more limited, like my ELS system, would be nice when I needed to make a part to get one of the machines working again. No doubt about it. But I should be able to keep my self busy for a few years getting to be good with the machines I already have. And don't worry about any comments I make about automating machines, it's just my eyes turning green with envy now and then!
