Turning a nose cone on the lathe (1st attempt)

by Lathe on Oct.04, 2009, under Lathe Videos

After being kind of chalenged I thought I would give turning a nose cone on the lathe with my ball turning tool a go… here is the result. What do you think?

    Thank you.

    Glad you like it :-)

    Good work there!

    Erm…. Yes, definitly.
    The lathe I had already, and the tool…..
    The only thing I paid for were the cutting tips!!

    It was made from scraps of steel that I had accumulated over time :-)

    I don’t know if you have seen any of my other videos? But this tool can acheive freehand shapes that (IMHO) CNC could not.
    CNC has to be all planned out and pre-designed. You lose some of that spontenaity!

    Thank you for the comment.

    Hi, Glad you like it…. The design is free from

    w w w . Bedair . o r g
    (I like people who share their ideas for free :-) )

    It is well worth making this tool IMHO.

    I’ve just watched your videos, your workshop is as messy as mine :)
    I’m quite intregued about the operation of the motor, what does the pipe that points to the eccentric do? …. I’ll go post a comment on there later.

    ” Keep making swarf !! “…I’m trying, but things keep getting in the way…late for work!!!

    to do spherical ,this tool is way more cost effective than cnc.

    That’s an elegant little tool. Brillant !
    I can already think of several specialty tool applications. impressive.
    Please check out my little engine. search for K1 air motor. ” Keep making swarf !! ”

    Cash flow prevents exploration into CNC….. I would have a go if it was made available.

    I’m not sure how easy I’d find it but it’d be fun to try.

    I actually have things that I would like to make for which CNC would be the very best option…. 30 of the exact same part!!!
    But I’ll just have to practice my accuracy instead! :-)

    CNCs are dead easy once you understand the codes. The trig math still baffles me a lot… but if you can do this working on an engine lathe, it wouldn’t be hard to translate it to a CNC. It is a neat and wonderful little tool that you used in the . My buddy at the shop said the same as you but caught on real fast.He found it easier than an engine lathe that he normally turns parts on..you could do it. I was Paliative care Nurse before and sussed it all out.

    “That’s impressive” That’s what I thought the first time I used it :-)
    It really is a simple build and very easy to use.

    5 years…. You’ve got some time on me! CNC….. The thought makes me shudder…. All those numbers!! Brave guy! :-)

    Happy that you liked the videos.

    Thank you, glad you like it.

    The tool was made and slightly modified by myself but as stated it’s a Steve Bedair design, I couldn’t have made any of the nice shapes in my projects without it!

    That is impressive. I came over here to this after watching you turn a ball knob. Now that I see you do it, it looks wonderfully simple.. elegant bit of machinery. I’ve only been working as a machinist now 5 years, came to it late in life.. and self taught on a CNC… but I value the craftsmanship that this takes. Enjoyed watching it.

    Thats some lovely toolmaking there mate!!! The cutting tool is a good design.

    To see modifications to this tool design and a mini version I made for a 7×12 mini lathe visit

    Give the site a good look over and if you have stuff to contribute then please do so.

    Go to Bedair (dot) org to see the plans for this tool and give the inventor all the credit.

    Thank you Steve, the design works wonders!!

    Thank you, as stated before the design is not mine, Steve Bedair is the designer….. I just built it to his design with a few adaptions of my own thrown in.

    I have to wonder what tool you were looking for with a handle like “BigCockvanHugenDong” !?!? :-)

    Ralph.

    wow, awesome tool, great design

    Hi,
    I made the tool but did not design it (design – Steve Bedair . org)
    The tool is set up for a cone with a much larger radius than the workpiece, it is aligned toward the rear of the workpiece and cuts only a section of a much larger sphere.
    This makes a cone (or – ogive)

    If you watch the video and think about what I have written above I’m sure it will become a little clearer?

    Thank you for the comments.

    Ralph.

    thanks for up loading the video, you solve my long time question of how to make sphere using late machine. if you made the too holder you are very talented machining shop owner, I am sure you mast have made different tools for making you job production easy.
    question, tool rotation is fixed, how you can make a cone or curve or eliptical cutting peace as their angle of rotation gradually has to change? I will be thankful if you answer me.
    by the way you are great talented person.

    same as wheel nuts really. the end doesn’t vibrate loose because the cutting force is trying to turn it clockwise (tighten)
    Just don’t try running the machine backwards (unless it’s a left hand thread)

    Hi, Thank you, Glad you like the vid’ :-)

    Yep, that’s me…. Just a little play on words!

    You tube would not let me have the name with the spaces in it??

    Good stuff…. The site is a great place to learn and talk to people with similar interests.

    See you around there :-)

    Forgot to tell you. I build steam engine scale models as well. I have a scale machine shop in my spare bedroom. Is your name at mad divided he ad? I must be putting it in wrong thats the only name like yours here. I joined the site fly2000jtb there as well Thanks again.

  22. fly2000jtb

    Thanks will do, and thanks for the advice too, cool video I forgot to say so last comment.

    Hi Joseph. The metal used for the ball is mild steel, It also cuts very well in stainless.

    The tool is also all mild steel, except the tip, which is carbide.

    There is a link to the Steve’s site from the contacts box on my channel (click on my name in the top right box to find my channel page) I have also listed it in the comments on this video page, you just have to take the spacing out of the address!

    But I’ll also put it here.

    Have fun :-)
