Greetings from the Oregon Institute of Technology machining class! Your videos have helped me finish my projects faster, thank you.
Greetings from Illinois. thank you for watching and I am very very glad that I helped you in some small way with your technical machining. I had a friend that taught Shop in Portland many years ago
@@mrpete222 We had to machine a live center, 60° treads, acme treads, but the Morse taper was by far the most tedious. We didn’t get to internal treading but we would have if the campus didn’t have a scheduled shutdown as a safety measure after Thanksgiving. I’ll definitely recommend your channel to my professor for future students. Happy Thanksgiving!
thank you, it brings back memories of when i was a small lathe operator. job loss due to foregn competition . but i used to be able to hold a half a thou on the diameter on turns up to 8 '' in length, not to easy on an old worne out swayback .one never knows how much one will miss something untill you do.
I have learned as much from your videos as I learned from reading many old machinist books found on google books. I wish I could have been in one of your classes. In my high school in Savannah Ga we had no shop class. If you are looking for more topics, a video on cutting dovetails would help many of us. Thanks a million!
Great video and looking forward to viewing others. Reading books and magazines maybe one approach, but viewing a video is like having a mentor right then and there....with a replay and rewind function to boot.... :) Keep up the good work!
Thank you from Brisbane Australia. I am not a machinist so your video is extremely helpful. Now all I have to do is what you did.
regards
Robert
Thanks for watching
@LowCountryCamo WO! That's deja vu!! I was just checking my email before going to my shop to start the introductory video on cutting dovetails. First a lesson in how to measure them & then a project cutting one.THANKS FOR WATCHING & FOR THE KIND WORDS> pete
I always enjoy watching videos's like this, I wish I had a half decent lathe and milling machine. haha
Great accent, very clear instructions.
+Andrew wood Thanks for watching--get yourself a lathe!
Mr. Pete, thank you for your great videos.
Hey Mr. Pete,
In school we were taught to dykm the peice, measure an inch in your calipers and mark anywere on the peice. Then measre the diameter of both of those marks to tell what the taper per foot is.
you never cease to amaze me! i love this stuff!
Another excellent video set explaining the set up and use of the taper attachment. I have one on my lathe but never really used it for any precision turning, I will be much more confident to use it now. Thank you for taking time to make these great videos. Sky cam seems to be working well for you. Any chance of doing a set on machining chuck back plate, a common enough problem for those wanting to add a 4 jaw or six jaw to there home set up please.
Great video as always Mr. Pete, thanks for sharing!
Tubalcain, I just watched your acme threading video. You were talking about your Starrett acme thread gage. You said you could buy cheaper ones from China but they were probably stamped from old Schlitz beer cans by a barefoot boy in a hut with a dirt floor (I laughed out loud, that was funny). I'll sound like a fool if I am wrong but the caliper you are using in this video sure looks like a Chinese one.
Nice instruction - thanks. Looking forward to getting my first lathe put together and start doing some machining.
Thanks for watching
Wish you were my shop teacher Mr Pete!
@johnpaulharris or beter yet, put a dial indicator on the work zero it, use the carriage stop to move 1" along the taper accurately, then check the dial indicator reading and it multiply by 12 for one side or 24 for both sides and you should have a very accurate inch per foot measurement of the taper.
Great video Mr. Pete! Could you please do a vid on your variable feed setup. I would like to do that to my 13" southbend. I cant decide on what type of motor to use. Thanks
I don't know about cat making money but cummins must. I have a cummins engine in my crane and the oil filer cap went missing. I checked with the cummins parts supplier and the cap was $82.00. I went home and made a cap with some 3" delrin and turned it down on my Atlas lathe. Added some RTV and I put a screw thru the top with a chain so it won't bounce out.
Hey Mr. Pete. I saw your other video on dovetails. I have been searching high and low for the TRIG tables you have. Wondering if you can make me a copy or suggest another resource. Thanks Tony B .
Hi Mrpete I am a novice to lathe work and I love your videos. I am trying to figure out how to turn an internal MT#3 on a 12" Atlas lathe. I don't have a taper attachment and the compound doesn't have the 3.19" of travel needed to cut the length of the taper. My only other thought is to offset the workpiece in a steady rest, which I don't have yet. How would you do it?
You might want to try buying a MT#3 reamer and going from there.

There are many for sale on ebay.. search trigonometry tables
I'm not a machinist but I have a question. Is my thinking correct? You needed to run your boring bar upside down to use the lathe as it was already set up. The taper started out wider and narrowed as it went deeper (in). Why did you not run the boring bar up right and cut your taper starting with the narrow end and getting wider as you went to the left (in). Would that present other issues avoided by running the boring bar up side down? I suppose it gave effectively the same results either way. I find your videos very educational. Thank you for making them and sharing your vast knowledge in detail. Cheers.
rick dees You feed large end to small, because the boring bar has to be able to enter the work. If you did as you ask, the boring bar runs the risk of crashing into the mouth of the work as the bb gets deeper. However, it IS possible to run as you suggest, provided you account for the smaller opening and adjust your bb accordingly.
In order to match the external taper exactly, with out disturbing (reversing the taper attachment) you simply run the lathe in reverse. This requires that the tool be turned up side down in order for the tool to cut properly.
ola ,eu sou torneiro e ferramenteiro
esses videos do machine shop são muito bons porque eu também faço reparos de elementos mecânicos
Wow--I've never done that
can you explain the boring tool position in more detail
@@tonyferster Cutting on the back of the work means the taper angle is = cutting the OD taper on the front side. Means using lathe spindle in reverse.
If he used the front and bored normally, the taper angle would need to be changed from + 1·5° to - 1·5°.
gracias por compartir tanto conocimiento y oficio en verdad me sirvió de mucho usted vera yo trabajo en la industria metalmecanica de argentina MUCHAS GRACIAS
I use a Morse Taper gage for the #2 and #3
@ragnarokzero1988 although you would have to have the taper attachment removed of course
@tbonaviso We are lucky he has time to teach us something. If he was standing at the photo copy all day we would get no more videos. Go to your local library.
Please show how the mechanics on taper bar that moves the cutter in the y axis, How does it work with the cross feed?
Thanks

I think the nut that connects the cross feed to the drive screw is removed so the cross feed is free to move and is then able to 'drift' with the taper attachment as it is fed along the work.
T=up
A scientific calculator also works
or just get a calucator with sin, cos, and tan, much better
