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

[heriberto2271]

wow its something usefull in the tool room. its simply amazing but its aplicable in larger pieces ?

best regards

[fly2000jtb]

You dont seem to need cutting oil?!? Is it al or steel? very cool I want one too! Thanks for posting the web site to get them Joseph T fly2000jtb

[Dividedhead]

@fly2000jtb I use carbide tips, quite forgiving... They will and do cut very well on steels and brass bone dry. Ali usually I use oils to prevent the welding of the material to the tool tip.

They are not too hard to make as long as you have access to the tooling? You may, as I did need to alter the design slightly to fit your own requirements? But it should be ok....

If you want to ask more details etc visit MadModder (address in annotations at end of vid) lots of smart guys on there! :-)

[x19710]

This is awesome!! i've got to give this a try! thanks for posting video, thumbed up!

[Dividedhead]

@x19710

Thank you.

Glad you like it. Happy it's inspired you a little too :-)

[110samec]

I like the music.

[Dividedhead]

@110samec Good stuff :-)

Sorry if I randomly went on.... Just I've had a spate of not very nice comments on some of my videos recently. Hence my semi-negative spin on the possibility of the comments meaning.

Music is by Solas. From the album "Another day" Just in case you were wondering?

Ralph. :)

[110samec]

Nice background music!

[Dividedhead]

@110samec It's so hard to determine inflection from written words. Sarcasm or not? It's the exclamation mark that throws me.

An Interrobang might have been of more use if intended as a jibe ?! (i.e. ? meaning "uhh" and ! meaning "what") I suppose this day and age if it were intended as a nice comment a :-) smiley might be better?

Anywho, either way I like it and that's why it's there....

Hoping that it was meant in a nice way? :)

[miketheknife2]

great job and thanks i just got a mini lathe and this will get me one more step it the right direction.

[Dividedhead]

@miketheknife2 Thank you, glad it has helped you along the way :-)

[aflatminor]

Hi David- a fantastic job there mate..

If i could just offer one tip- before you start to polish with the emery cloth, spread an old rag over your carriage as the carborundum will eventually wear the slides..

Cheers for the the vids, most educational..

[Dividedhead]

@aflatminor Who's this David character?

Anywho, Fair point on cleaning the ways, usually takes place at the end of most working sessions (usually).

Glad you like my efforts, Not perfect but will usually do!

Ralph.

[aflatminor]

@Dividedhead

Ha!! sorry, i didn't have my reading head on!! (thought the first part of your username was David!!)

Again- smashing vids..

[grieske]

Nice work!

[Dividedhead]

@grieske Thank you. Glad you like it  :-)

[PhantomMigKiller]

You betcha....!

[Dividedhead]

@PhantomMigKiller

Did I miss something?

Is that a reply to a question/statement or a term used to indicate you like the video/tool/work ? :)

Just not sure?

Either way.... I'm going to take it you like it and run with.... Thank you. :)

Ralph.

[PhantomMigKiller]

@Dividedhead It means- "Nicely done!"

[kiotikid]

Nicely done! What would be the approx. maximum diameter workpiece that could use to form a ball or do a radius cut?? Thank you for your consideration! KK

[Dividedhead]

@kiotikid

The largest I have turned with this is a ~50mm diameter hemisphere(see hemispherical press punch video)

I haven't gone larger than that due to the height of the tip above the rotating turret and the stability of the tool tip could become an issue too?(bigger lathe,larger tool)

Convex cuts are a strange beast.. It's hard to get the tool in to make tight shapes. I.E. a ball socket. but sweeping convex cuts of ~150mm can be made(see radius turner demo' video)

Hope that helps?

Ralph.

[Axbent]

I like this flute music who is it?

[Dividedhead]

@Axbent In the end credits!!!

Solas.

[Axbent]

@Dividedhead where? ;)

[butkatrello]

I ;ike the irish jig

[Dividedhead]

@butkatrello So do I.... Who'd have thoought :-)

It's by Solas, jusy in case you wanted to know :)

[bubblewrapboy99]

You should put a nut on the shaft so when you are done you can just back the nut off and whatever your turning will just unscrew with no problem at all.

[Dividedhead]

@bubblewrapboy99

Good call! Nice to know people are thinking while watching :)

That would work well with this shape and any where the back was left alone.

I'd have to make something else entirely for the turning of balls/knobs etc as the cutter goes all the way round to the arbour. (see other video)

Still, you've given me another thing to add to my "round tuit" list, a release mechanism for the balls!!

Thank you for the comment.

Ralph.

[jacktheripped]

this kind of cone is clled an ogive. it's curve is a section of a circle. to make a real nice cone the ratio of length to diameter should be 3:1 or greater up to 5:1, any more than that there's no benifit to aerodynamics.

[Dividedhead]

Hi, I have ogive in the video tags but never put it in the title?

I never got into the mathematics of the whole thing, this was just to prove I could make such a shape to someone who said it wasn't possible.

Nice to have such stat's in the comments though, as this is what most people looking for "nose cone" would be interested in.

:-)

[turtlemann14]

i like, i need something like this for lens crafting (acrylic rod)

did you make or buy?

[Dividedhead]

Hi,

I made it with plans from Steve Bedair's wedsite.... I'll put a link in the description.

I just altered the tip type for my own needs.

Some info on that in the comments on the ball turning vid' I made.

This will certainly cut plastics.... But you might need some sharper tips? Carbide is generally quite blunt and might heat the surface up and give a rough finish?

[turtlemann14]

i find that a carbide bit works just fine as long as there is plenty of clearance ground into it, mid range 1500 to 1000 rpm and cutting fluid

[Dividedhead]

Fair enough.

I wasn't sure as the formed tips are quite blunt (close up). Unless you have the sharp aluminium cutting ones. I've never used them, but the edges look like razors!

The tool isn't that hard to make if you have access to a milling machine as well.... you need the mill' for 3 parts. The slot, the cutter holder "L" shape and the seat for the cutting tip. You could saw and file the "L", but the others are IMO best with a mill'.

[turtlemann14]

indeed and thank you. i will look into making one

[wackedoutdude]

Another awsome vid i never go to pub now i would rather be watching stuff like this and saving money i hope to buy a mini lathe one day.

[Dividedhead]

Thank you, glad to see it's inspiring to some.

The pub gets up to 2 visits a week from me and that's only to play pool and erm, play pool!! :-)

A good second hand machine (peatol) is where I started off about 4 years ago now.....

Saved up for a larger lathe and a milling machine and then slowly lots of tooling too.... it's amazing what you can find out there, lots of older gents selling tooling they can no longer use.

Good luck.

Oh, more videos coming soon too , Xmas hol's and all :-)

[wackedoutdude]

weve got a harrison m300 at work and im just in the process of making a verical attachment for milling slots am using the compound slide that weve got spare of a harrison L5 and the only reson im making it is so i can make a ball turner like yours. Or thats the plan.

[Dividedhead]

Tried a vertical slide once.... We didn't agree!!

So I purchased a mill! :-)

Lucky to have some spare funds at the time.... Just stopped going out for a few months!

You will not regret making this tool, you can use it for styling as well as the intended functions.

Not too sure about your fixing points etc there are a few versions pictured and written about in the forum I post in..... Madmodder ( d o t ) Net.

Take a look around, you might get some more ideas?

[wackedoutdude]

Mill is better my old work had a cincinatti milacron and that was awsome. But im trying to use what ive got and for now a milling slide is better than nothing. Ive got a few handles ect to make so a ball turner will make it easy and it looks the part. But 1st i need a mill to make one hence the need for a milling slide. Im having to drill and tap the cross slide to mount it. Who is the artist for this music mate?.

[Dividedhead]

Good luck! The handles will come thick and fast once you have made this tool.

The music is by a group called Solas.... in the end credits!

No one ever reads the credits!! lol!

You are aware that videos of the build and the finished item are expected! :-)

This being a videos site and all.

Ralph.

[dtiydr]

Good work there!

[Dividedhead]

Thank you.

Glad you like it  :-)

[jeetendrag10]

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

[Dividedhead]

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.

Ralph.

[slome815]

I love conventional machines, but I learn CNC in college, and I can say it is really easy.

Even for single projects it is really easy to just write a quick program in G-code and let the machine do the work. And you can really make some shapes that are nearly impossible with conventional machines.

[Dividedhead]

I realise that many people do love the CNC machines.

I however am still inclined to think that you lose something in the "bespoke" department.

With CNC you have to plan such shapes beforehand.

You do not just let the metal guide you to it's final shape!

(I rarely follow plans 100% accurately!!)

I feel that Manual machinists and computer aided machinists will never see the others side fully.... Agreeing to disagree will undoubtedly be the final outcome!?

Good to hear others views though.

[slome815]

Don't understand me wrong, I love conventional machines. I own a Myford ML7 and it 's the best machine I ever bought.

A CNC machine is very usefull though. The biggest problem with a CNC machine is the price. Learning to operate a cnc machine and learning how to program it is easy.

[MechanicalFinger]

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 !! "

Mechanicalfinger-

[Dividedhead]

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!!!

Ralph.

[ricksullivan]

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.

[Dividedhead]

"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.

Ralph.

[ricksullivan]

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.

[Dividedhead]

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! :-)

Ralph.

[PopeBuck]

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

[Dividedhead]

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!

Ralph.

[Dividedhead]

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!!

[BigCockvanHugenDong]

wow, awesome tool, great design

[Dividedhead]

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.

[123kkambiz]

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.

[Dividedhead]

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.

[fly2000jtb]

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.

[Dividedhead]

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 :-)

Ralph.

[fly2000jtb]

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

[Dividedhead]

To see my latest modification to this tool go to w w w . MadModder . net and search (tools)

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

[Dividedhead]

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

Thank you Steve, the design works wonders!!

[fly2000jtb]

forgot to ask what site address is steves plan for the tool on? the tool holder you are using to make the ball and nose cone? Thanks for the response if you do, Joseph T (fly2000jtb)

[Dividedhead]

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.

w w w . bedair . org

Have fun :-)

Ralph.

[fly2000jtb]

is the metal aluminium?

[moto9ll]

well done! i looked over the plans and photos to build one.....i dont understand how the screw that holds the column together doesnt vibrate loose..if you rotate your ball turner clockwise does the screw tighten up? and will it loosen if turned counter clockwise?

[Dividedhead]

Hi, Thank you.

The plan on Steve's site shows the hole threaded inside the turret. This does not go all the way through.

This allows the screw length to be adjusted by use of a file or emery paper so that when it is screwed tightly into the turret (so that it is hard up to the top) it allows a little clearance between the base and the screw head so that the turret rotates easily.

I hope that reads ok? If not I will gladly answer a PM with much more detail.

Ralph.

[UKnick80]

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)

[32006210]

fuckin' greattt , i like it

thankssssssssssssssssssssss

[pitbike2006]

wow did you make that tool or where can i get one

[Dividedhead]

Yes I made it but the plans are free. If you watch to the end you will know wehere to find them.

[nakkadu]

Square

[nakkadu]

Oooooh.......it's round!

[Dividedhead]

Acctually it's an 'Ogive' and therefore somewhat conical. You facetious git!

[Dividedhead]

Glad you found it!

I assume you mean the nose cone rather than the thrust end of the rocket? In which case making it a bigger arc and longer workpiece would probably work?

The term 'spin' ... spinning is a different art altogether, this is turning. just so you know :-)

[forcetoregister]

Cool. I was searching for something like this for while. I'm into rocket engine building and always wanted to see a rocket nozzle being turned on a lathe. This looks close but I'd love to see you try to spin a nozzle.
