Turning Accurate Conical Features.......5 different ways !!! Take a Look 

You are a born teacher. I’ve said in here before that I’m a welder / fabricator of 30 years and for the last few years I’ve took a new role in the same company as a Toolmaker. I work in a small team with a couple of good guys but your videos are so informative. Thank you!

Glad you are back on your feet. Enjoyed the reminders of different ways to skin a cat as it were. I have forgotten a few of those in my 74 years but also a couple of new ones. Have you tried a hermaphrodite caliper....that is what I have used instead of a caliper to mark a point. Something about using a caliper for marking makes me grit my teeth ;-)

All good methods to get you close Joe . I have used your other method before to get them dead spot on , taking into account the radius of the tool & tangent point . 👍

Joe, thank you for demonstratibg these tips. I suspect that many of us will be trying at least some of them before we forget them! ;)

You are a Master of your craft, and I love watching you work. Thank you for the excellent videos.

You make this look so easy! It does take practice but I am persistent! Thanks for the info!😊

Thankyou Joe, loved it! So good to see you back at the lathe again! 🙂👍

Hey Joe, great to see you back on your feet... I spent about 6 months on the couch after a motorcycle incident a couple years back - don't take walking for granted anymore 😆

Great job Joe, on taking a task that can be difficult in practice and making it manageable. There's a lot of info in this one- Reminds me of hitting the diameters/angles in cutting a chamber reamer. Thanks!

D-d/L= Taper , now you can do anything! D big diameter...d small diameter....L = length

Very well explained techniques and enjoyable to watch. Good luck from Spain!!

You have some great videos. I've been a toolmaker for 18 years (self employed 11 of those year) and I still learn plenty from you.

Joe, you've just blown me away with those simple (when you know it) methods of producing the required taper on a part. The bank is going to be full!

Like your video on the different methods! Want to mention I had seen a video from the UK where an eBay China gear down motor (one of the 2~3 rpm 12 vdc jobs) was used to drive a shop-made socket which fit over the compound knob (on my old SB 10K). Provides very smooth drive this way. I added a reverse to the one I built so it moves in both directions and simply used some pipe PVC for a handle which holds the motor, wiring, switch, etc.

Great to see you back - thanks, content is superb.

Thanks Joe, you always give great technical advice on how to measure and turn things. I would have to say of the half a dozen people that I watch on here on machining yours has always given the most information on how to get to exact spec. Not being negative to anyone that takes the time to make and upload these video's but I would say you and mrpete222 have given me the most information on how to do thing as a hobby machinist working out of a shed. That said I wish I had known the little nub trick about a week ago when I was making a new handle for my quick change tool post, I left myself without a way to get an accurate measurement and had to blend it in which obviously means I would not have hit a spec'd measurement if it would have been that critical but I try even if it's not important so when it does become important I can do it.

Another great way of showing us how to do things.

Another trick from out of your sleeve and up mine! Thank you! Woody

Thanks Joe. All good info.

The 6th way is to use a CNC lathe. Great video Joe.

Great tips, learned a lot of tips I wasn't aware of especially for saving time.

Thank You Sir for the video. Always enjoy them.

Hey Joe have you ever had an apprentice? Just curious because it seems like you enjoy teaching. If anyone had the opportunity to apprentice under you I'm quite sure they'd learn a lot ....

SNL Coneheads skit to follow 😉 Great video, Joe!

Thanks for these tips Joe. These will really help!

thanks for the upload joe, much appreciate. greetings, ben.

Hi Joe, thanks for this video, really useful for us guys just starting out! I’d really like to see you make a collet to fit an unknown spindle taper, buttress thread and all!

Great video Joe! I learned something as always. 👍👍

I’m not a fan of using calipers to scribe lines either!sets my teeth on edge when I see other RU-vidrs do it.

always great information Joe 3.14...cheers from Florida, Paul

Thanks Joe from New Jersey

Thanks for the video Joe.

Nothing like learning old school!

Thank you Joe great tips

Great info Joe, thanks man...

Interesting and much appreciated.

Many thanks for the tips!

Thanks Joe great video

As usual a jersey boy leads the way lol nice job joe thanks

I've had chamfer tools ground to various angles for years.

Thanks Joe 👍👍😎👍👍

Hi Joe Hope you are well. Very interesting to show so many ways to achieve the same result. Are your subjects inspired by work /jobs you have done or a project that has dropped on your desk so to speak for you to carry out. Thanks again.

You're the man...

It always seems a bit weird to me counting on a line you scribe with a vernier caliper, the line itself is about 1 2 thousands of an inch thick? So it seems that 1-2 thousands of an inch is the most accurate you can get. Maybe I'm wrong though.

Joe... You ever do crankshaft journals? It seems to me I need a crank machine, but a four jaw chuck in the tailstock on a bearing might do... What do you know on that?? Thanks, Mark

No. 5? Not your style Joe. No. 4 seems to work for me fine. Same for internal conical features. Thank you for sharing Joe, much appreciated as always. Stay safe and be happy. Best, Job

Love those tips! Enjoyed watching, thanks.

Thanks Joe. How's the leg healing?

2:40 that's what she said

*ATF has entered chat*

In this video and in some of your other videos you will show a way of doing something and mention you prefer not to do it that way but you don't give any details on why. I am interested in the reasons you have behind your decisions.

👍👍

Please put a microphone on your tshirt .

Scratching a layout line on a part, is what cheap calipers are for.

Good knowledge, thanks joe!

*ATF has entered chat*

Instead of scribing with caliper could you scribe with tool giving exact known position on dro?

Blimey!! This was a brilliant lesson. Just yesterday I was battling to get this right.

You're really an excellent teacher. 👏 I learned a lot from you... Thanks sir 😊.

Absolutely magical Joe, I have learned so much from your presentations, this is a superb shop Gem for a newbie like me. Kind regards from your 71, year old apprentice.

10:40 is exactly what I was looking for

That makes my brain hurt 😮

Hi joe greetings from australia, love your hints and tips ,you make it so easy to do, very uncomplicated. Just wondering if you ever have done anything for us on setting up to turn parrallel, or maybe how to make our own test bar to fit into the headstock morse taper. Thankyou for all your efforts , it is really appreicated. Before computers this information was really hard to get other than word of mouth, that wasn't allways right anyway. Just can't thank you enough.

Great lessons! Questions…lathe tool dead sharp, or is there a nose radius? RPM/Feed for turning the aluminum stock?

It would be a shame to miss the opportunity of this mans knowledge of the craft , so when he puts it up there for free even ! jump at the chance as I have , you will be better for it . I am 73 and just enjoy this.

As always...Simple, Elegant, Doable.

Another great video that I have saved for quick reference. I am at the age where if I don't use something frequently, I look back at notes to make sure I have the procedure correct

Thank you. I find your videos very informative and enlightening.

These are very good workable tips. Thanks Joe

I guess you have all the angles figured.

Always a learning experience

Thanks so much for that step by step turning angle; My question is how can i set my tool position in an event where am using a swivel tool holder , Secondly how can i set my determined angle and by which tool

As always great tips ! 👍

Useful video again Joe. How do you go about putting radii on tapered features, like say on the end of a location pin that blends on the taper?

Wow - that was entertaining and DENSE - I'll watch that again about 10 times- thanks so much

Great to see so many practical techniques to get this done. You are such a treasure.

great video on different methods getting a taper. As new hobby metal lathe user, this was helpful. However, i wish you would have went more in depth on how to create a smooth taper during the sliding action. Ive recently cut some tapers but have trouble cutting them smooth because my finger action to move the slide is not smooth is my guess and I have to keep stopping. Maybe i just need to do it more times to learn the smooth action of it.

Thanks for sharing 🙏

If you use a cutting insert with a known radius on the cutting edge, with a little bit of plane geometry and trigonometry, you can calculate for the theoretical sharp corner of your cutter insert and you can with normal measuring of diameters and lengths, turn accurate tapers and cone shapes easily within .001" without using any guess work and/ or scratch lines, using those offset dimensions. This is for manual hand turning as , I am sure, CNC machines will calculate compensations for the radius size on the cutting insert. You can even estimate these offsets with no calculations if you accurately draw it @ 100 to 1, so eg., a .006" radius on the cutting tool becomes .600" on your drawing and measure the offsets x and y with a scale to get a sharp corner dimension. As Joe emphasized, you must know your start, stop positions with the carriage accurately and with repeatability., setting carriage stops and 'zero" cross slide, and compound positions is everything.

Always more to learn and be refreshed - thanks Joe, great stuff.

Many years ago after working in a machine shop for sometime, I realized why I should have paid more attention in trigonometry.

Great practical shop ticks and tricks as always. Joe, thanks for taking the time to post this information.

My old metric starrett calipers have an attachment to turn them into a depth mic that I use a lot. I used that scribed line trick to turn a bunch of barbs in peek plastic with a form tool recently. I have one of those compass with the hooked end for registering on the faced end. Pretty handy really. A lot of the stuff I picked up over the years is very old, but still useful.

very good video joe

Many thanks for sharing your expertise.

Thanks Joe, another lesson learned. Good to see you on both feet 😉 Cheers Neil

I just got into cat skinning and only know of two ways as of now. I would be happy to learn of other cat skinning methods as I am a noob.

Very much ado about nothing!

Thanks for all the great techniques Joe. I have a rotary table with an unknown center taper. What techniques would you suggest for determinig that taper?

I don’t like scratching lines with callipers either, so I bought myself a cheap marking calliper from one of the Chinese websites, it even came with a carry case & spare scribe. For around £10 (under $20) I find it really useful. Unfortunately it’s not digital, but it doesn’t do me any harm to keep my hand in with analogue measuring equipment from time to time. Great to see you back again Joe, I really hope you’re not pushing yourself too hard. Take care.

You're not an engineer Joe , you're an artist. As a turner for over 40 years in all sorts of materials from steel , bronze , and currently , plastic , it's a pleasure and an education to watch your videos.

The challenge with using the compound slide is you loose your digital readings. I made up a block with a vertical hole and a large flat face on it. This then bolts to my tailstock on the operator side. I have a heavy piece of rectangular key steel that I have drilled a hole in one end. I set this guide bar to the desired angle using my readout and a DTI. Easy calculation to do. If you do it over 6 inches or so you can move the saddle along six inches and the toolpost in the desired amount and set the keysteel at zero at both points. I dont use the compound slide because it voids all the tool settings using a DRO. Then to simply machine a taper use your power feed and a DTI. Keep the needle on the DTI on zero or any other preset number and the lathe will generate a long uniform taper. Ideal when you need to make matching tapers as on a propeller and shaft. The initial work required to make a block and have it easily attach to the tailstock does take a bit of time but once you have done it the time is paid back easily. Almost like a copy lathe.

I'm not a machinists these tips will be put to good use,thanks for your efforts🤗😎🤗😎

Another great lesson now put in time and space from a true professional! Thank you Joe!!

That was a great set of tips! Thank you. I'm about to make some sets of bevel gears so I'll try these methods out and see what I like.

I never trust angles on a compound. Thus I calculate the diameters and go for that method

Another great video Joe! Just watching at the end there reminded me that I recently learned that there are two ways to measure depth on a vernier! Blew me away.

I never trust angles on a compound. Thus I calculate the diameters and go for that method

Thx! I'm assuming similar operations are available on the Mill as well?
