Morse taper turning

[@colinwarner7762]

Hello Alan, another great video, thanks so much, Colin.

[@enotsengineering]

Glad you enjoyed it

[@dalejones4186]

Hi. I absolutely love this channel. I am new to metal working and your ability to teach both verbally and visually is the best. Few people can do both. Thanks for the videos and the work it takes to do them. I am learning so much. Thank you.

[@enotsengineering]

Hi Dale Thanks for your comments, it takes me longer to do the film and editing than making the parts.

[@BillyTpower]

I totally agree, great content, wish they were longer, i could watch for hours

[@The007Weasel]

Hi Alan, as a hobby machinist I've had exactly the same problem as you showed for using the compound slide method......run out of travel, BUT have always tried to leave my tailstock offset well alone, after spending many hours struggling to adjust it to schieve parallel cuts.....and the best I got is 2 thou taper over 6" length. But your really neat trick with the set-up bar & DTI at 12.40 is a fantastic idea thanks, which should reduce re-adjustment to just a few minutes, and be spot on too.

[@bernardmauge8613]

this way of checking is only good if you use and absolute straight tube with no surface imperfections. I am not moving my tail stock until i get a test bar the length of my bed.

Excellent machining going to be a beautiful looking tool

[@tomherd4179]

Video is great, thanks. I have a question somewhat related. Do you have any ideas on how to “hold” a 2MT dead center in some sort of vise (??) so a hole can be drilled in the end that goes into the tail stock?

[@enotsengineering]

Hi Tom I had this question some time ago and the answer was given by one of my viewers which was. To hold the big end in a chuck and use a steady on the small end.

[@tomherd4179]

@@enotsengineering That sounds like the best approach so far, and I have the rest as well to do it. Thanks !!

[@davedigs]

good project i have the same problem with the revolving centre but if i use the lantern tool post its ok i ended up buying a small live centre with interchangeable heads its been really useful

[@enotsengineering]

Hi David I hope mine will be as useful

[@Mobile-ct1yf]

Why did you not set with a sine bar and then use your automatic feed on longitudinal cut get a better finish then file and polish to finish

[@enotsengineering]

Hi. At the time I didn't have a sine bar, but I did show a way of using the DRO to set an angle in another video. see kzbin.info/www/bejne/f4CskKd_hshomtE

[@Jaxter1137]

Thanks I learned a lot from what you showed. 🤪

[@charlesbradshaw1285]

But surely your tail stock offset is only correct for a distance between centers. ie. the same as that when you set it using the sleeve?

[@enotsengineering]

HI Charles. Yes that's right, If you have a setting piece close to the same length as the part you're making. Then it"s a good guide to start turning the taper making small adjustments to get the correct finished result.

[@BillyTpower]

Hi Allan, as un trained machinist, I'm easily confused about to0l geometry. What i don't understand is that if it's important to get geometry right when i'm grinding the tool then why do experienced guys like you and hundred others do things like change direction of cutting using the same tool, i am missing something obviously . if your tool is ground to cut right direction then how can it be used in left direction. This is very confusing , i'm not referring to cutting to fit in tight corners, I mean straight cutting in the middle of the workpiece .

[@enotsengineering]

Hi Billy It depends on the type of cutting tool being used. If you grind a tool by hand you may grind it to cut on the left hand side of the tool only which is normally the case. But if you are using an insert some insert tips are symmetrical like the triangle inserts and have cutting edges all round so you can cut to the left or right just by adjusting the tool holder to face the other way.

[@BillyTpower]

@@enotsengineering example of wht i'm trying to relay is the same tool at two different angles.... 08:18 05:25 07:50

[@enotsengineering]

Hi Billy. The tool used has a cutting edge on the RH and LH side and a rad to the tip so you can use either side. a bit like a thread cutting tool.

[@BillyTpower]

@@enotsengineering ah ok I see now

[@davidcolwill860]

Just a thought. Could you rotate the QCTP through 180 degrees and use the same toolholder but with the tool sticking out backwards. This has helped me in similar situations. Thanks for sharing.

[@enotsengineering]

Hi David Yes I can see that would have worked on this job as it was held between centres and was a longer bar, so no chuck to get in the way. Good Idea.

[@bernardmauge8613]

Thanks for the tutorial. I am a novice and am learning about cutting tapers. For clarity you should film the position of the part to be cut in relation with the compound and or the carrier. I got lost in your demonstration. What is obvious to you is not for me anyway.

[@enotsengineering]

Thanks for the tip!

[@ke6bnl]

is that a dead center that you put in the end with the MT?

[@enotsengineering]

Hi Ed The morse taper I was making had a small revolving centre fitted in it.

[@Δημήτρης-η4ρ]

When you aligning the tailstock back to center I think that if you mark the exact position that you took the mesuring on the test bar and mesure the same place when you flip it would have a better accuracy, any way i have never seen this method for setting the centers, it is offcourse alote easyer than rollie's dad method.

[@enotsengineering]

Thanks for watching

[@davidcuster4618]

What is the polishing tool you are using?

[@enotsengineering]

Hi David Its an emery stick. see my video on how to make one. kzbin.info/www/bejne/mpbRhmatn7GtrZI Alan

[@Rolingmetal]

I think your compound was probably long enough.

[@fabrizioleonetti1806]

non se capisce che dici

[@enotsengineering]

Hi Fabrizio Se non mi capisci, vedi i sottotitoli.

[@fabrizioleonetti1806]

non sono in italiano

[@enotsengineering]

Qualcuno può tradurre i sottotitoli dall'inglese all'italiano
