I had to smile about the engineer comment. I was that engineer who couldn't understand the machine shop constantly asking if I really wanted it that size? It was during a previous life when I was designing wire and slick line equipment here in Aberdeen Scotland. Admittedly it was half a lifetime ago so I think I may have learned a bit since that time. Thanks for the pointer from the machinists point of view - and the memory.
I've contributed to the final part from both the shop floor and the keyboard, so I feel qualified to make that comment. CNC machines are a different animal, but manual machinists need tips like this to keep them sane. I also taught a course on design for manufacturability to University of Texas engineering students. I was amazed at what they didn't know. So were they. It always went very well. Thanks for the comment.
Hi, allow me to say that you are the ONLY one that makes videos where someone thinks: "...exactly this I wanted to know for years". thanks for sharing your knowledge. The day that you will come to Florence let me know, I will show you my city and we take REAL Italian coffe ;-) Take care and stay save
Stumbled on this video on 12th July 2023 just in time for making accurate angles on mating parts. Thank you, Joe for all of the incredibly clear advice you've given for so many of us over the years. Long may it continue!
At last someone succeeded in explaining me in a comprehensive way why I had to learn all that trigonometry back in highschool allmost 35 years ago. Thanks and greetings from Belgium.
Oh that was very clever indeed. To quote a New Zealand saying, “you really do know your onions!” I am super impressed. The only thing wrong with the whole approach is that I did not think of it..Bravo! Not only that but exactly the same trick will work with my mill. Double winner! Thanks Joe.
Beautiful. I LOVE it when practical trig shows up. I still believe most kids would get trig if they had a lathe and a mill to work with. AND a good, clear, teacher like you. Thank you!
Gee Joe, it is with great interest that I watch you channel. Even though I won’t ever need this information, for this ‘ol maintenance engineer I certainly do admire you and your approach/application to a situation such as this. 👍
That's great. Personally I'm a CNC guy. But watching these videos in you channel helps me on the manual lathe and mill for small projects around my shop. Keep them up. They are very helpful. Thank you for taking the time to show it step by step. You are a great teacher. Two thumbs up!!!!
Hi Joe, your content is a little advanced for me at this point. It took me a whole weekend to machine 8 levelling feet for my lathe my first lathe so small steps. However even being a novice your presentation was done in such a normal way without you needing to pull out the technical terms and language that for us novices make you sound like a brain surgeon and goes straight over the top of our heads, you have a way of conveying a circumstance that is understandable to many, thank you. Your clearly putting it out with a genuine desire to help not to stroke your own ego.
I love this one Joe! The way you break things down helps so much. I find I was over thinking this issue and your explanation on the board and then in the shop got me on track. God Bless you bud. I agree with the vast majority of your subscribers that your an excellent teacher and I feel personally blessed to have found you. I'm 46 starting again since being disabled and you truly inspire me. The classes I'm taking plus all the other videos have left me more confused. I understand you better than anyone and I really thank you for what your doing. I'm proud to call you one of my instructors. Tim Ditmore Matrix Gunsmithing Lake George, CO.
My biggest thank you for this video. I was in need of a morse taper 4.5 sleeve to fit a drawbar in my 1924 Oscar Ehrlich lathe, and with the help of your outstanding explanation I've just turned a perfect taper. Took me 15 minutes to dial in the compound slide, and now have a perfect fit MT4.5 sleeve.
I'm ashamed to admit this, but I'm still going to... I did not know this method. It's so simple! To those people who are having trouble grasping it, watching the video while standing in front of the lathe is a good suggestion that someone else mentioned. Thank you, Joe!
I'm coming to this video about 7yrs too late but you're a great teacher. In ten minutes you've explained what it took my maths teacher several weeks to explain to a disinterested teenager 😂 When you add a bit of relevance trigonometry suddenly becomes interesting.
Trig is always the answer... what an eye opener this info was when I began machining. It all started by asking what a Sine plate was for... Then the explanation, then Jo blocks, then confusion, then a million tests and now I use trig all the time. Thanks for the info.
Hi Joe, thank you so much for your videos. As a 65 year old I regret never taking any trigonometry classes. You break it down and make everything seem so simple
Joe, I used this technique last night in order to set my compound cut an precise 8-degree taper for an ER11 collet cavity for a holder I made. Worked like a charm! Here I thought I would need to go and buy a sine bar to do this but with a little math and your technique I saved some much needed dough! Much Thanks and keep up the videos. This is priceless knowledge that you are choosing to share and I greatly appreciate it.
Joe, I am not a machinist but I love watching this type content. I want to thank you for taking the time to create these videos explaining not only the how but the why. You have the heart of a teacher and the ability to convey in understandable terms the concepts and techniques involved. Michael
I really appreciate the rigor of your methods. Assuming the least, getting the precision measuring instrument as close to the parameter you are controlling as possible. Saves a lot of frustration, and a similar trick can be used in many situations.
I was a carpenter for 35 years back when we use to cut roofs, before premade trusses. (roofs are all angles). This is exactly how i use to figure angles/lengths,rises, diagonals . If you buy a construction master calculator, which i used for years, this will all be extremely simplified. On the calculator there are three keys called run, rise and diagonal (the three parts of a triangle). You can enter as fractions 1-1/4, or decimals 1.25, or metric 31.75 or whatever. The amount of weird angles on all the different pitched roofs with hips and gables and interrupted angles and so on are endless. Greatest tool ever invented for us dumb carpenters.
Some of these shop calculators require the user to convert the minutes to a decimal before they can proceed. 31 degrees 22 minutes is not 31.22 degrees. I've seen some of these lead guys down the wrong path and confuse them more than help them, but if you are used to using them, I'm sure they are a real time saver. I'll stick with my book. 40 year comfort zone.
I've been trying to get a 1.4 degree taper on a hardwood sprue using an old Lesto Scintilla with a removable cross slide, very tricky, but your method produced results on the 2nd attempt. After sanding smooth and a sawdust polish, the taper was measured at 1.409 degrees. Thanks for the time to make this video, its much appreciated.
I have been toying with the idea of single point cutting a rifle chamber using the info provided in these conical feature videos, leaving just a few thousands for the reamer to clean providing a perfectly concentric bore. I am not pioneering this processes, I just wouldn't have the confidence without you. Thanks Joe
Its great joe,in the beginning it was a little difficult, but as i stand by my lathe and repeat what you explained,suddenly it become clear to me. Thanks a lot for your time , and i hope you will go on to help us.Again Thanks Hans, from Holland
This was way over my head , but I enjoyed watching it , I can tell you know what your talking about, Loved your video on threading away from the chuck. I haven't ran a manual lathe in 30 years but I'm about to retire and I'm going to buy one just to play with. I will watch all your videos for a refresher coarse .
Another piece of simple trigonometry. No expensive sine bar, no even more expensive gauge blocks. Thank you! I learned trig a million years ago in a third world school. I had the world's worst math teacher. So I found the Barnes&Noble College Outline Series on trig and taught myself. Then I taught my buddies and that cemented it in my mind. Trigonometry is the machinist's best friend. Nowadays there are online aids to learning it, such as the Kahn academy, and whether you use a book or online, every machinist should learn it. At least the rudiments. It is not necessary to learn the identities -- just how to solve a right triangle.
The best video I've ever seen explaining how to get tight angles. Man whoever said I'd never use High School math in life lied to me. I use it all the time. Thanks for sharing. Best Wishes n Blessings. Keith Noneya
Excellent series! Your practical tips are gold for a hobby machinist like myself with just a couple machines in my garage and no professional experience.
Thanks Joe for the trig refresher. Even better, you demonstrated its application on the lathe. That tip is a gem for setting the compound. Thanks again.
Joe, I realize you did this video in 2016 but I just wanted to let you know how much help you've been to me while doing things at my work that I've learned from you. I'm very much a novice when it comes to machining but I'm just good enough to make things work the way I need them with the help from your videos and a few others. Thankyou again for all the great videos Joe you really help guys out like me a HUGE AMOUNT.
Great lesson on how to apply trigonometry to the cross slide and the compound using the graduated dials. This video was a breath of fresh air!!!!! Thank you.
I got a Hardinge lathe and made my own cross slide and compound so I had no graduated marks for the angle and needed to cut a backing plate for a chuck with the Hardinge 4 degree taper. I failed three times trying to use protectors and digital angle fingers and a few other items to double check the angle. I had one that would work but wasn't true. Only hit at the very back of the spindle nose taper. I just got done setting up using this method and I believe it's going to work great. Thanks for all the knowledge you are giving away and keep up the good work.
Thank you, Joe. I'm making an ER32 collet holder for a D1-4 spindle and this tip allowed me to cut the angle in the holder that mates to the lathe spindle. Thanks again
Thanks Joe for another excellent tips video. I am sure i speak for many people in that we greatly appreciate these, there are few places this sort of information can easily be found - especially for us home shop machinists that have not had formal training. Keep them coming :)
This is especially useful when trying to mate components machined previously. In the past I have had to make sure I did not disturb the compound slide setting between machining components which can be a nuisance when the operations do not follow each other. Keep up the good work, much appreciated.
This worked perfect to set 7.125 degrees to open up the taper on my D1-4 backplate. Thanks Joe, as a hobby machinist I have learned a lot from your videos. It took me ~10 times to get less than .001" error on the cross slide measurement, but I did get it. Then checked how true the angle was by checking with a .0005" test indicator along the original taper. Zero dial movement.
Hey Joe, good stuff. I really appreciate your videos like this one. You present well and it is refreshing to see tips from someone with current, relevant practical experience on TH-cam (in contrast to so many sloppy home-shop guys like myself). I practiced with this technique and was able to hit my chosen test taper spot on. Thanks!
I had some jobs come in once that had like that out to 3 decimal places. I managed to cut them and set up a sine bar to check them with and they were right on. A few days later the engineer came back and wanted them recut to a different angle. I told him I'd never had a print before with such precise angles called for. Turns out that they were just experimental angles on a prototype and were drawn on a computer which had put in all the decimal places. I had cut them on a cnc. The next ones I just did on a manual lathe using the numbers on the compound and they worked fine for him. Yeah, engineers mostly seem to have no idea what goes into making parts to some of their prints. Ok, enough of that rant. I never would have thought to do an angle with the method you've shown. Thank you very much and keep them coming.
This is some good stuff... I've used gage blocks and indicators before to trig out the angle, but never once did I thought to use the tailstock as a reference. This is gold for me. Thanks Joe!
Check the tailstock and stay near center and your angles will be incredibly accurate. Be sure your tool height is equally adjusted to center for the best accuracy.
You earned another subscriber! All your methods seem to be very, very good. I appreciate that you spend so much time explaining these so that anyone can do it. Thanks!
I use the same technique plus to make it easier to set the target angle. I clamp a 1m strip of wood across the bed at right angles. The wood is located to the right of the tail stock. The wood sticks out the front of the lathe. I then clamp a 1.4m length of square section steel onto the side of the top slide. The end of the steel rests on the wood, but is not clamped or attached to it. I now make a first attempt to adjust the angle of the top slide using Joe's method. I mark where the steel now rests on the wood by using the steel like a ruler to mark a line. After each adjustment to set the target angle, I mark a new line on the wood. This gives me a history of angle setting attempts. It is also MUCH easier to make very fine angle adjustments at the far end of the steel than at the top slide. It takes longer to explain than it does to do. It speeds up setting the angle to fine tolerances.
And my trig students in school did not think there was any value to learning the functions and their application. I am now retired but If I was still teaching, your video would be my teaching tool.
Oh my - so simple when you know how! so many thanks Joe for passing on this invaluable knowledge - Going to try this on my 70 year old Myford ML7 Also thinking of trying to make some angle gauges, we will see. Again many thanks and best wishes to you and you family.
Retired now, I worked for many years in Jig Boring shops. Just about every job that came across my desk involved tolerances in tenths of a thousandth. Angles usually were no exception. We came up with a method using the side of the compound to set the angle with an indicator in the spindle. First set the compound angle as close as possible to start with using the graduations. Then consider the side of the compound as the triangle's hypotenuse, pick an even number like 3" or 4" for the side, then calculate the other two sides of the triangle for the desired angle. set the indicator to zero just touching the compound. Use the lathe readout for the distances in the X (cross slide) and Y (long travel) axis to set the opposite and adjacent sides of the triangle. You will need to double the X cross slide number as it reads in diameter! Just as with Joe's method, it's possible to set angles within seconds of arc!
Thank you very much for sharing your knowledge and publishing the videos! I am just a bloody newbie and your videos have helped me immensely. Your videos are clear, concise and very well presented without any annoying babbling. Basically, you taught me via youtube. Thank you! Bernhard
We need more like him, with experiance and history to teach our youth. Because those who have potential will instantly understand what he is talking about and soak up the knowlege. And i'm not talking about machinist class, i talking about math class
Great video. I love it. When I need that kind of accuracy I usually indicate along a sinebar. Very precise also and rules out leadcrew inaccuracies. Works in milling machine too.
Pure genius, instead of dreading trying to cut an accurate angle I look forward to trying. I have to make some grinder hubs with internal tapers so will use this method. Thanks for sharing your knowledge.
@@joepie221 Thanks Joe, I'll make sure I pay careful attention to the tool height. Just to let you know I used the technique you demonstrated for turning very thin walled components to make a 10 thou thick acetel spacer that was missing from the seal set of a 30 ton press we bought cheap as it was leaking hydraulic fluid. The OEM part was only available as part of the full seal kit which was very, very expensive. So, thanks again. It just shows how useful sharing knowledge is.
Hi Joe, I'm new to your videos, I'm self taught what I know about machining and your informational videos are excellent, this last compound angle video is one awesome idea, just what I needed to cut some morse angles. What I want to say about figuring angles is get that construction master calculator and with the run/ rise/pitch/diagonal functions you can figure those angles so fast and easy without getting into fancy geometry stuff. Thanks again for making life easier when cutting precise angles.
Hi from New Zealand Joe. I've just binge watched your entire channel and subscribed. You have fantastic technical info and new techniques I haven't seen before. Hope you can make more videos for us. Don't worry too much about camera angles / steadiness and production values etc if this will put you off putting out videos. Your content is high quality and speaks for itself. Cheers Tim
When I was getting my engineering degree, we had a saying. "You can't land on the moon with whole numbers.". All joking aside, as a young engineer, I felt totally disadvantaged. Here I was, fresh out of school, expected to tell a machinist with 30 yrs experience what to do. I didn't have the benefit of an apprenticeship although it should be a requirement of engineers. I had to learn everything the hard way. I got some razzing but the company machinist understood. I am grateful for their teachings.
A college degree is an important thing, but nothing compares with the knowledge an experienced machinist has for making a product. A good relationship with the valuable crew producing that product makes everyone involved look good.
Nice one glad I'm not the only one who think that about the odd engineer. Very timely for me as I had been considering the very problem. Thanks for your time and passing on the knowledge.
Very clever approach. Just be aware that its accuracy relies on your tailstock quill surface alignment with the spindle rotation axis. Any wearings or dents on the quill surface might set your taper off.
Am I ignorant to think that this approach to cutting an angle doesn't rely on any alignment other than accurate measurements? I'm new to machining. How precisely can a 90 be measured. And if the 90 is true, you can make any angle right?
You just got me out of jail! thank you, I'm making a D1-4 to large 5C collet adaptor and was stuck with setting the angle for the short taper. Great video.
Thanks guy! I'm a home hobbyist and I got an RFQ that included an inside taper at 10.62*. I wasn't sure I could even quote the job 10 mins ago. Cheers!!
Thanks a million I tried this and got to within .0005 on the dial indicator of a 30 degree angle repeatably several times, tightened the gibs a wee bit and was finally able to get it to go to zero every time. My lathe reads 60 where others read 30. And yes in response the the comment below I did sweep the quill of the tail stock and it is dead on from one end to the other. Again thanks a million. Worth
Joe, that was amazing, thanks. I always put a sine bar against the tailstock and turn cpmpound until I got 0-0 on the indicator, this is much better! after 45 years I spent in toolroom and job shop, you amaze me!
Love your videos. Trig Math is easy for me, but I have never thought about using it for setting machines up. I have always focused on using 'traditional' methods. Well done (Chris - New Zealand)
Joe, thank you. I’m a self taught amateur hobby machinist. I’ve used any of your techniques building engines that actually run. The angle technique on the compound slide is especially useful. I’d never get angles correct otherwise. John
Great technique. I had to cut .4 degree angle over 8 inches. It was just to track a belt on a roller so the tolerance was open. Figured if I am to do it, do it right. This help greatly.
Wow. I am really loving your teaching methods. Great vids. I just got a 7x10in mini lathe to start working with, cause that's all my wife would let me get. I one day I'd love to have a big boy lathe and a shop of my own. Please keep the lessons coming. Thank you.
I spend a lot of time using trig (soh cah toa) for mill work. That is one great tip for lathe work!! Sure beats the eye loop! Thank you for passing on your knowledge.
What an elegant solution! I want to make an ER collet chuck. This procedure should help me accurately set my compound to the 8 degrees required for the collet taper. Thanks.
Absolutely Enlightening. Forgot to commend and Thank YOU most graciously for Showing Sharing and teaching us these innovative practical gems that are worth their Weight in GOLD. We can't BUY this. Thanks a zillion Cap'n. May Your SHADOW ALWAYS STAY LONG !!! aRM
Another useful video thank you for that. During the Coronavirus I have been in machine shop 101 using your videos as my guide. You a a great teacher. I have been making tools. Fly cutters, vise stops on and on. My problem is that I saw an adjustable stop that bolts onto the back of a Kurt vice that you have made. I want to make one but I need to see it again for some of the fine details. My problem is that I cannot find it again! I do not remember the topic of the video it was in. I have been searching for a couple days through your videos with no luck. I would appreciate very much if you could point me to the video where you show it. I'm 64 years old like a kid in a candy shop, this is fun! Thank you for what you do. From chilly Michigan.

Its super accurate.

Great lesson on how to apply trigonometry to the cross slide and the compound using the graduated dials.
This video was a breath of fresh air!!!!! Thank you.
Thanks for watching. Try it out.
I got a Hardinge lathe and made my own cross slide and compound so I had no graduated marks for the angle and needed to cut a backing plate for a chuck with the Hardinge 4 degree taper. I failed three times trying to use protectors and digital angle fingers and a few other items to double check the angle. I had one that would work but wasn't true. Only hit at the very back of the spindle nose taper. I just got done setting up using this method and I believe it's going to work great. Thanks for all the knowledge you are giving away and keep up the good work.
Good to hear. This is very accurate.
Thank you, Joe. I'm making an ER32 collet holder for a D1-4 spindle and this tip allowed me to cut the angle in the holder that mates to the lathe spindle. Thanks again
Thanks Joe for another excellent tips video. I am sure i speak for many people in that we greatly appreciate these, there are few places this sort of information can easily be found - especially for us home shop machinists that have not had formal training. Keep them coming :)
Glad to help.
Great tip. Practical trig application. Fantastic explanation helps demystify the complexity of such a complex part. Thanks again, Joe.
This is especially useful when trying to mate components machined previously. In the past I have had to make sure I did not disturb the compound slide setting between machining components which can be a nuisance when the operations do not follow each other. Keep up the good work, much appreciated.
This worked perfect to set 7.125 degrees to open up the taper on my D1-4 backplate. Thanks Joe, as a hobby machinist I have learned a lot from your videos. It took me ~10 times to get less than .001" error on the cross slide measurement, but I did get it. Then checked how true the angle was by checking with a .0005" test indicator along the original taper. Zero dial movement.
Glad it helped you. This is an incredibly accurate setup method.
My son asked me the other day what good is trigonometry, now I can show him, thanks
Hey Joe, good stuff. I really appreciate your videos like this one. You present well and it is refreshing to see tips from someone with current, relevant practical experience on TH-cam (in contrast to so many sloppy home-shop guys like myself). I practiced with this technique and was able to hit my chosen test taper spot on. Thanks!
Outstanding. the bigger the triangle you use, the greater the accuracy. thanks for trying it and thank you for the comment.
I had some jobs come in once that had like that out to 3 decimal places. I managed to cut them and set up a sine bar to check them with and they were right on. A few days later the engineer came back and wanted them recut to a different angle. I told him I'd never had a print before with such precise angles called for. Turns out that they were just experimental angles on a prototype and were drawn on a computer which had put in all the decimal places. I had cut them on a cnc. The next ones I just did on a manual lathe using the numbers on the compound and they worked fine for him. Yeah, engineers mostly seem to have no idea what goes into making parts to some of their prints. Ok, enough of that rant. I never would have thought to do an angle with the method you've shown. Thank you very much and keep them coming.
Thanks Dale. The longer the hypotenuse, the more accurate the angle. Give it a try. Be sure to watch the next video on how to inspect them !!
I cut a JT33 taper with this technique and it worked perfect! Thanks for the tip!
Awesome Joe !
So simple it hurts ?! Love your classes
This is some good stuff... I've used gage blocks and indicators before to trig out the angle, but never once did I thought to use the tailstock as a reference. This is gold for me. Thanks Joe!
Check the tailstock and stay near center and your angles will be incredibly accurate. Be sure your tool height is equally adjusted to center for the best accuracy.
You earned another subscriber! All your methods seem to be very, very good. I appreciate that you spend so much time explaining these so that anyone can do it. Thanks!
Thanks for the comment and sub.
I use the same technique plus to make it easier to set the target angle. I clamp a 1m strip of wood across the bed at right angles. The wood is located to the right of the tail stock. The wood sticks out the front of the lathe. I then clamp a 1.4m length of square section steel onto the side of the top slide. The end of the steel rests on the wood, but is not clamped or attached to it. I now make a first attempt to adjust the angle of the top slide using Joe's method. I mark where the steel now rests on the wood by using the steel like a ruler to mark a line. After each adjustment to set the target angle, I mark a new line on the wood. This gives me a history of angle setting attempts. It is also MUCH easier to make very fine angle adjustments at the far end of the steel than at the top slide. It takes longer to explain than it does to do. It speeds up setting the angle to fine tolerances.
great video Joe - your teaching techniques are wonderful
Thanks. Glad you found it helpful.
And my trig students in school did not think there was any value to learning the functions and their application. I am now retired but If I was still teaching, your video would be my teaching tool.
Its a hard fact that machining needs a strong base in geometry and trig. At least it makes it easier if you understand it.
Oh my - so simple when you know how! so many thanks Joe for passing on this invaluable knowledge - Going to try this on my 70 year old Myford ML7
Also thinking of trying to make some angle gauges, we will see. Again many thanks and best wishes to you and you family.
A very elegant technique! Good clear and concise explanation. Keep the videos coming Joe.
I'm learning so much. Many thanks Paul
Retired now, I worked for many years in Jig Boring shops. Just about every job that came across my desk involved tolerances in tenths of a thousandth. Angles usually were no exception. We came up with a method using the side of the compound to set the angle with an indicator in the spindle. First set the compound angle as close as possible to start with using the graduations. Then consider the side of the compound as the triangle's hypotenuse, pick an even number like 3" or 4" for the side, then calculate the other two sides of the triangle for the desired angle. set the indicator to zero just touching the compound. Use the lathe readout for the distances in the X (cross slide) and Y (long travel) axis to set the opposite and adjacent sides of the triangle. You will need to double the X cross slide number as it reads in diameter! Just as with Joe's method, it's possible to set angles within seconds of arc!
It is amazing how much you can learn in this trade. I haven't stopped learning yet. Joe, your videos are just great. Keep up the good work!!
Joe, I used this method today (to cut a precise outside angle) and it worked perfectly! Thanks!
Thank you very much for sharing your knowledge and publishing the videos! I am just a bloody newbie and your videos have helped me immensely. Your videos are clear, concise and very well presented without any annoying babbling. Basically, you taught me via youtube. Thank you!
Bernhard
We need more like him, with experiance and history to teach our youth. Because those who have potential will instantly understand what he is talking about and soak up the knowlege. And i'm not talking about machinist class, i talking about math class
Thank you.
this was like the clouds parting and the sun shining through - brilliant and thanks for such a simple concise way to hit crazy angles. awesome.
Thanks for the comment. Glad you liked it.
digging through your vids now, subscribed, learned more in the last 30 minutes than the previous week. from California. gotta get outta here...
Great video. I love it. When I need that kind of accuracy I usually indicate along a sinebar. Very precise also and rules out leadcrew inaccuracies. Works in milling machine too.
Merci from France Joe, this trick will be very useful to me. François
Greetings from Austin Texas! Glad to hear it. It works well.
Pure genius, instead of dreading trying to cut an accurate angle I look forward to trying. I have to make some grinder hubs with internal tapers so will use this method. Thanks for sharing your knowledge.
Thanks. Be sure the tool is extremely close to center when you do this. Any deviation high or low starts to flatten out the angle.
@@joepie221 Thanks Joe, I'll make sure I pay careful attention to the tool height.
Just to let you know I used the technique you demonstrated for turning very thin walled components to make a 10 thou thick acetel spacer that was missing from the seal set of a 30 ton press we bought cheap as it was leaking hydraulic fluid. The OEM part was only available as part of the full seal kit which was very, very expensive. So, thanks again. It just shows how useful sharing knowledge is.
This old post just became relevant to me now, glad I have a good reference.
Best channel on youtube on the topic, just second to none. Thank you for doing this
Thanks for the comment. Its a solid technique.
Hi Joe, I'm new to your videos, I'm self taught what I know about machining and your informational videos are excellent, this last compound angle video is one awesome idea, just what I needed to cut some morse angles. What I want to say about figuring angles is get that construction master calculator and with the run/ rise/pitch/diagonal functions you can figure those angles so fast and easy without getting into fancy geometry stuff. Thanks again for making life easier when cutting precise angles.
Hi from New Zealand Joe.
I've just binge watched your entire channel and subscribed. You have fantastic technical info and new techniques I haven't seen before. Hope you can make more videos for us. Don't worry too much about camera angles / steadiness and production values etc if this will put you off putting out videos. Your content is high quality and speaks for itself.
Cheers
Tim
Thank Tim. Great comment. Stay tuned and thanks for subscribing.
When I was getting my engineering degree, we had a saying. "You can't land on the moon with whole numbers.". All joking aside, as a young engineer, I felt totally disadvantaged. Here I was, fresh out of school, expected to tell a machinist with 30 yrs experience what to do. I didn't have the benefit of an apprenticeship although it should be a requirement of engineers. I had to learn everything the hard way. I got some razzing but the company machinist understood. I am grateful for their teachings.
A college degree is an important thing, but nothing compares with the knowledge an experienced machinist has for making a product. A good relationship with the valuable crew producing that product makes everyone involved look good.
Nice one glad I'm not the only one who think that about the odd engineer. Very timely for me as I had been considering the very problem. Thanks for your time and passing on the knowledge.
Thanks Will. This works great.
Very clever approach. Just be aware that its accuracy relies on your tailstock quill surface alignment with the spindle rotation axis. Any wearings or dents on the quill surface might set your taper off.
Am I ignorant to think that this approach to cutting an angle doesn't rely on any alignment other than accurate measurements? I'm new to machining. How precisely can a 90 be measured. And if the 90 is true, you can make any angle right?
Measure the part not the tool? Am i wrong?
Just made my second internal morse taper using your system. Works a treat. Thanks for sharing your experience with us. Good on ya mate.
Great to hear!
You're a great teacher man! Ive been in a pinch a few times and had a video of yours save me! Keep it up thanks!
Glad it helped!
You just got me out of jail! thank you, I'm making a D1-4 to large 5C collet adaptor and was stuck with setting the angle for the short taper. Great video.
Thanks. It works very well.
Thanks guy! I'm a home hobbyist and I got an RFQ that included an inside taper at 10.62*. I wasn't sure I could even quote the job 10 mins ago. Cheers!!
Thanks a million I tried this and got to within .0005 on the dial indicator of a 30 degree angle repeatably several times, tightened the gibs a wee bit and was finally able to get it to go to zero every time.
My lathe reads 60 where others read 30.
And yes in response the the comment below I did sweep the quill of the tail stock and it is dead on from one end to the other.
Again thanks a million.
Worth
Glad it worked out for you. Its a solid technique. Thanks for commenting.
Joe, that was amazing, thanks. I always put a sine bar against the tailstock and turn cpmpound until I got 0-0 on the indicator, this is much better! after 45 years I spent in toolroom and job shop, you amaze me!
Thanks Frank. Thats hard to do to guys with experience like yours.
Love your videos. Trig Math is easy for me, but I have never thought about using it for setting machines up. I have always focused on using 'traditional' methods. Well done (Chris - New Zealand)
Thanks Chris. It works very well.
Joe....I recently had to make an R8 taper and this video made setting up the angle so easy....Thanks again!!
Glad it worked. thanks for trying it out.
Joe, thank you. I’m a self taught amateur hobby machinist. I’ve used any of your techniques building engines that actually run. The angle technique on the compound slide is especially useful. I’d never get angles correct otherwise. John
You can get it within minutes this way. Super accurate method.
What a great review of my plane geometry class of 59 years ago... I loved geometry and still love it!!!
I can't understand your drawings but I understand your practical work on lathe & dial indicator method,thanks & best wishes for you from india
Love your lathe Joe, I had a 15 x 50 with taper attachment what a machine.
Great technique. I had to cut .4 degree angle over 8 inches. It was just to track a belt on a roller so the tolerance was open. Figured if I am to do it, do it right. This help greatly.
This is great I've been struggling with these taper cuts for awhile !! Thank you ...
This will get you extremely close. EXTREMELY
I cannot thank you enough Joe! Master Artisan in action.
Used this method to set to bore 1.5" taper per foot for wheel hubs on hydraulic motors. Worked great and very easy to set up. Thanks!
Wow. I am really loving your teaching methods. Great vids. I just got a 7x10in mini lathe to start working with, cause that's all my wife would let me get. I one day I'd love to have a big boy lathe and a shop of my own. Please keep the lessons coming. Thank you.
Glad to help
Well done, I was sent to class today. Just when I think I'm making huge strides, I have so far to go.
I spend a lot of time using trig (soh cah toa) for mill work. That is one great tip for lathe work!! Sure beats the eye loop! Thank you for passing on your knowledge.
What an elegant solution! I want to make an ER collet chuck. This procedure should help me accurately set my compound to the 8 degrees required for the collet taper. Thanks.
Absolutely Enlightening. Forgot to commend and Thank YOU most graciously for Showing Sharing and teaching us these innovative practical gems that are worth their Weight in GOLD. We can't BUY this.
Thanks a zillion Cap'n.
May Your SHADOW ALWAYS STAY LONG !!!

I'm glad to pass this along. Do the same when the opportunity presents itself.
NIce to see you use a box wrench, I see so many using open end wrench like they never been taught
You are pretty darn good at what you are doing! Keep up with those exellent videos!
Thank you.
Another useful video thank you for that. During the Coronavirus I have been in machine shop 101 using your videos as my guide. You a a great teacher. I have been making tools. Fly cutters, vise stops on and on. My problem is that I saw an adjustable stop that bolts onto the back of a Kurt vice that you have made. I want to make one but I need to see it again for some of the fine details. My problem is that I cannot find it again! I do not remember the topic of the video it was in. I have been searching for a couple days through your videos with no luck. I would appreciate very much if you could point me to the video where you show it. I'm 64 years old like a kid in a candy shop, this is fun! Thank you for what you do. From chilly Michigan.
I looked for a while, but couldn't find the close ups. Maybe a short video is in order.
hey Joe, watching this for a second time, always good and so simple best wishes, Paul
Thanks Paul. Its super accurate.
Thanks Joe, very informative as usual and as expected of your presentations. Hope you're recovering from your recent taste of winter.
As an absolute beginner/hobbyist, this was EPIC information! Don't worry brother, I hit the sub button.
Awesome, welcome.
