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

[@allanmanning5131]

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.

[@joepie221]

Glad you enjoyed it.

[@AlabamaTree]

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!

[@joepie221]

Glad to help.

[@geoffnightingale2846]

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.

[@skipgoryews1356]

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.

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

[@brucewilliams6292]

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

[@bobvines00]

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! ;)

[@drevil4454]

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

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

[@joepie221]

Many thanks.

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 ;-)

I definitely agree, Joe has some great tricks up his sleeve.

[@grntitan1]

A person should never get to the point where they feel there is nothing left to learn.

[@joepie221]

I'm sure we can all teach each other a few things. It probably just depends on what kind of work you do. I've always been heavily into custom, prototype and development work, with some repair thrown in. I've enjoyed it all.

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

[@tomherd4179]

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.

[@MegaLostOne]

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.

[@joepie221]

Critical isn't always required, but its good to have options.

[@matthewperlman3356]

Always good to have a wide selection of options to best fit a particular scenario. Thanks for the tips!

[@MichaelMoranGearHead]

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.

[@steventhompson3507]

I very much enjoyed a video that you put out Jo regarding turning precisely angled conical features. So your video on setting the compound to precise angles was usefull coupled with that last demonstration of what to do if you need to meet a set diameter externally as well rather than working to stock diameter. Bit of a faff to set up but it all worked like a treat. Precision angle jionting two precision diameters to each other over a precise distance. Really pleased thankyou.

[@joepie221]

Glad it was helpful!

[@rexmundi8154]

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.

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

[@outsidescrewball]

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

[@joepie221]

Greeting Chuck. A truly dead sharp tool ( nose radius ) is very hard to get a good finish with. I do break the edge for things like this, but only to remove the razor sharp edge. All the turning here was done by hand, so I can't comment on the feed. Feed for finish is usually driven by the nose radius of the tool. The RPM is never lower than 770 for aluminum and that can ( and will ) change with greater surface contact from a form tool. Since extremely sharp tools are hard to get good finishes with, its OK to establish gage or termination points first and finish with a radiused tool to get the surface finish desired.

[@TrPrecisionMachining]

very good video joe

[@NagashiChidorii]

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.

[@joepie221]

Learning to cut a long taper using the compound is an acquired skill. The very first thing you need to embrace is using 2 hands to do it. Don't try to turn the dial 360 degrees with one hand. That will influence the gibs on the compound and leave ripples on the part. Stopping will leave lines. Pass the crank smoothly from one hand to the other without pushing or pulling on the compound itself. Keep all your force true to the center of the screw and the taper should work out just fine.

[@donmathias1705]

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.

[@SlowEarl1]

[@joepie221]

[@jimmyboles3409]

Good knowledge, thanks joe!

[@mikemarriam]

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?

[@joepie221]

If possible, use 2 balls of different diameters and measure to the top of them once they rest in the hole, one at a time. Then trig it out. 2nd option. Set a stop on your quill and a controllable downward distance. Register an indicator in the taper and sweep it down the given distance. Triangulate it and trig it out.

[@mikemarriam]

@@joepie221 thank you for your response. I've tried the second method without much success. Nothing in the 18th edition Machinerys Handboook matches what I come up with. The first method seems much less subjective. I'll give that a try. Thanks again.

[@MachiningandMicrowaves]

@@joepie221 I hadn't thought of that trick, I often need to measure unknown very small diameter tapers. I just tried it on one I made using a 1.7 mm carbide boring bar. Using 4mm and 5mm balls and a depth mic it checked out remarkably accurately! Another one for the Little Black Book of measurement tips. Brilliant bonus info, thanks very much

[@glennschemitsch8341]

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.

Bad practice true, especially since the calipers are not typical sharpened to a point, so the line is all messed up or too wide. There exists actual marking calipers that have sharp pointy jaws with carbide inserts for just this purpose :)
