Mrpete222 I'm a little late to this party, but I really like your videos. I'm an old retired guy, I worked in an Air Force Precision Measurement Equipment Laboratory (PMEL) for 33 years, the last 12 as Flight Chief for the laboratory. My career involved highly precision measurements in the mechanical/dimensional area of the laboratory. I have a great deal of experience in measuring what the machinists produced, but I have no experience in how those parts were produced. I recently acquired a Bridgeport mill and have begun the journey into the science/art of machining, sort of the other side of my career. I won't live long enough to acquire the knowledge of true machinists but I'm going to do the best I can. Videos like yours are a HUGE help, thank you for posting!

Mr. Pete, You are the shop teacher every guy wishes he had!

Mr Pete, It never ceases to amaze me how you continually produce videos that are informative, interesting, and thought provoking. I guess it comes with many years of experience and a natural teaching ability. Your growing class is very lucky to have you as our youtube shop teacher !

Retired and still teaching! Excellent, Mr. Pete.......thank you.

I love waking up Saturday and watching a great Mr Pete video!

Thanks you. I found this very interesting and easy to follow. I still can't believe I get to learn from so many fascinating people all for free.

Always a great start to the weekend, a new Mr Pete video! "Turn this off if your sick of it" LOL, I have never turned off a Tubalcain presentation. Great video Mr. Pete! Thanks for sharing, some great info there! Looking forward to part 2.

Since I have started watching your videos I have found myself acquiring all sorts of tools, files, granite plate, dial indicators, indicator stands. I don't have a mill but the accuracy I have available to me now has greatly improved the machines I build. Thank you Sir!

Nice job Mr. Pete...your experience shined brightly in this video.

You were shocked it was that close? I bet when you park you car the lines are within .001's of each tire. You have the accuracy gene, Mr. Pete, and your enthusiasm about that is why we love to watch your vids.

I used the same layout method to machine the carriage stop V groove for my lathe .thank you mr pete for validating this method.

A good knowledge of trigonometry is the sure sine of a good machinist. ;-)

I'm addicted to your videos Mr. Pete. I refresh KZfaq several times daily in hopes that you have posted another...... My wife thanks you though 'cause it keeps me off the streets! LOL. Thanks as always.

Thank you Sir, I am glad to see the manual way still works just as good.

Well done, Mr. Pete. You made it easy for someone with no machining background and who hates math with letters to understand how to perform this operation. Thank you.

You are truly a national resource. I enjoy ALL your videos. I wish I had tool auctions where I lived.

I'm with ya. As always. You're never boring. Thanks for all you do.

Just goes to prove that there is no substitute for years of experience to work quite accurately with layout lines which many of us do .As you have rightly said many times , more than one way of doing a job and getting the same good result.

Man i respect people with this skills. Cnc takes away a lot out of the old school. I respect yr craft.

Mr. Pete, Thank you for an other wonderful vedio. I am learning much from your clear examples of how to do things in the machine shop. You are a great example of an excellent teacher. Sincerely, REA

I haven't seen this yet, but you SIR, have read my mind. I was about to do this today! THANK YOU!

Nice job on your layout to get that good of results! Thanks for all the great videos. Now to get of the computer and head to the shop.

Dear Tubalcain, your explanations take me back to 1965 Advanced Grade Eleven Trigonometry, where we all thought, what use was it beyond land surveying? ( most of the class were farmer's sons!)...only when I was in the Service did I see the applications ( navigation, bridge building, engineering in genera)l...now, at 71, I fully appreciate Pythagorean principles...thank you!!! Doc AV

This video is a condensed master class in layout, accuracy, and craftsmanship. Invaluable to any maker in any medium.

Extremely interesting video. You show how easy it is for the guy at home to get a good finish without over thinking the job. Thanks. Kevin from Australia

First V block I cut back in the mid 90's, remember using the layout method and it worked well. Still have that V block and still serves me well to this day.

I missed this when you first posted it. Just saw it now and it was worth the wait. Glad I hung in there to the end!

Thank you sir for the practical explanation. You and Joe Pie have helped me so much with this type of machining.

Hooray our shop teacher has returned. Great job.

Mr. Pete, may your teaching moments never end. I have done what you did with the same results. And I think pretty much about the same amazement that the fastest method was as accurate as the longer method. Thank you sir for all your years dedicated to the teaching of a great skill to a bunch of bone headed students.

And THAT is how you are able to do very accurate work on any random worn out mill with no DRO. Clickspring uses this method almost exclusively in his popular videos. It was so informative to see both methods compared side by side to prove the accuracy and show the importance of laying out your work.

Do that pretty often at work too. Suppose to be more accurate to use the math but if you can scribe accurately, you can machine just as good. And saved a lot of time too. Tks Mr Pete.

We used to learn & remember the trig numbers for the common angles: 30,45,60. If we did not remember we would calculate, so that for 45 deg, we would create a triangle with two equal sides of length 1. Then by Pythagoras, the hypotenuse was sqrt (2), which was remembered by the simple rhyme: "I wish I knew root 2" by counting the letter we got 1.414. So cosine (45) equals 1/1.414 = 0.707 and sine (45) is the same 1/1.414 = 0.707. I had not thought of that for a very long time. For sqrt of 3 we had: "O pleased was he who knew root 3", again counting letters gives 1.732. Remarkably pleasing to remember that. Thank you for such interesting & useful videos as I do need to make some stops for my mill.

Hello Mr Pete from way down under, across the pond !!! Thanks a stack for showing and sharing this via both methods. You have given us ideally the choice to decide on the best method (which would suit us), to get the job done. This is superb. Have numerous such projects we could now tackle to get crackin'. Much appreciated. And keep them rolling. All the best aRM

Great!! I'm gonna use this today on a project I have been working-on. Thanks!!

That was a great video. I made a rudimentary v-block about a year ago via some sketchy layout. I had no idea how to check the accuracy of the milling until now.

GREAT JOB MR. PETE. I LEARNED SOMETHING NEW. THANKS FOR SHARING.

Great video, timing was perfect as I have a project where I have to cut a v-groove. Thanks

Math aside Mr. Pete, and I am a big fan of the numerological arts, laughably, I was taught this as the proper way to do it. That, AND I never knew any better, or to look for another path. I think the tolerance of our machine tools more or less set me on a path to discover alternate course of action to find accuracy.... Thanx, G.

Watched this 6 years later (again) on using a 45 degree end mill (beginning minutes) to make a 90 degree V groove. Would like to see you actually use that 45 end mill some day. Don't ever think we don't go back to view your old videos, they are all precious lessons from the shop teacher! I will probably buy a 45 end mill to experiment with in making some v-blocks and a drill press vise jaw with a LEVEL groove as my current jaw was found to be way off in being level to the base. Maddening how things are assembled with such in-accuracies. Thank you again for all your efforts.

Sir, you have applied trigonometry to its best. I never miss application/method/knowledge given by a "Guru" like you. Thanks for this wonderful video. I really enjoyed it to the fullest. Best Wishes Sir.

thanks for the last part of the video. it shows us guys with a math skills of intro algebra not to be scared to layout and get the part close like you just did. i'm not a machinist but i took machine shop in high school and now just bought a small mill to tinker with for my motorcycle parts. i'm an ex certified welder now truck driver with welders, 2 lathes, and now a small bench mark mill at home. thanks for your videos!

Hi Mr Pete, been watching you videos for a long time ,and I have enjoyed everyone of them ,and I also enjoy all of your commentary...we both talk the same language...keep up the good work.......

Wow I wish I lived next door to you !What a great video and a great way to teach.thank you

Lyle, I loved it !!! Thanks much, Cliff

Great video!!! Thanks so much for sharing your knowledge.

Absolutely great Mr Pete.

Mrpete- you ARE the hands down the BEST teacher EVER!!! I absolutely loved this video To see the same result with the lay out lines as you did with the math was amazing- as always 2 THUMBS UP my friend!

Came out great. I think the use of an accurate scribe makes the difference.

This was super interesting to watch, really appreciate it. I know virtually nothing about machining, but am curious about at least learning the basic operation of it. Great video, very cool. Love your teaching style too.

LOL his milling videos have helped me very much. My popa, helped me as well but sadly he died before I was 13. But thank God for KZfaq and kind hearted people like this man's heart okif giving. I do many projects for myself and family and I've learned a lot just by doing but people has this man's year's of knowledge are really a blessing to have and being able to watch and learn even more. Thank you Sir God Bless you abundantly abundant. LYBIC Rebel..

That was really interesting! Thanks for the demonstration. Definitely a good watch!

Lyle thanks for sharing. Learn something every time.

Love this stuff Mr Pete, keep it up

Great job Pete!!!!

Hello, Mr Pete, thanks again for teaching another machine shop tips. It came to my mind what my woodworking teacher tell me long time ago. If you trace a precise line on the work why would you want to sut it. The line is the end of the cut. Have a nice week and I wait to see the next part.

I knew you would pull it out of the bag.....great job mr Pete.

Shocked? I wasn't. Yup, you are that good! Thanks for another great instructional video.

Good work! My first time to watch your video, and I already subscribed. I have a small home shop, lathe and mill, and already I am learning more from you. Thanks, and I look forward to watching more from you.

Thanks Mr. Pete, always a pleasure! It reminded me of SOHCAHTOA the great Indian Tee Pee builder that didn't have trig tables. Love to hear you tell that story! Also the Machinery's Handbook has a terrific section in the beginning for all kinds of geometry calcs. Looking forward to the tap holder build with the 45° W...should be interesting set ups.

mr pete your teaching videos are not boring, just wish i was as good as you.

Hi Mr Pete its Steve great video need to watch part two Thanks

Very good as usual MrPete!

Thank you! I'm working building 90° jaws for press brake. The the v point section ended up approximately 3/32 off the center. So once I re mill it. I will be starting the v notch plate.

Well described! I enjoyed and understand the process. Thanks for some well needed education!

"You can knock me over with a feather".😅 Always great content. Thanks Mr. Pete.

Great to watch such a detailed video

Could have used this video two years ago when I made my bench block. I got the job done, but it took much more work than needed.

thanks mr pete this is in current collage assessment your video is been very helpful

Just what I needed. Thanks ! 👍

good job mr. Pete..thanks for sharing.

I’m actually a tool and die maker apprentice and this is a gem. My leads show us a lot when they can because I also work on different metal stamping dies for wood connectors so I mostly do a lot of grinding on blades, punches, etc. as well as general die service, changeovers and troubleshooting on the manufacturing floor for the other leads so I do alot to say the least. When I have some downtime I practice on the drill presses and lathe machines from videos I watch as well as poking my leads brains. Haha. But anyway, insightful video and I will be trying to make my own v blocks.

Excellent teacher, thank you 😊

So easy to follow these videos and try it out on my own. Thanks

another great job and video Lyle !!

Really good information I learned alot! Thanks!

easy listening simplicity to follow, thank you for the video

Great video - thank you for sharing your knowledge!

Hi I don't mind the math, but the second method/option was pretty impressive. Excellent work. Ben

another nice video,Pete ol school. keep them coming

I'd touch off and do the math, which I enjoy, then my worn out Bridgeport ways and some dumb mistake would put me off center no matter what. But thanks for another great training video! I love knowing how I should do it, and always enjoy your teaching--ALWAYS.

GREAT JOB MR. PETE !!!

Thanks for the math lessons as well the machining lesson.

A Great video, Thanks Mr. Pete.

Awesome video. Thanks for sharing your knowledge..

Great Video Very helpful Thanks for sharing

Great Video... I find them all useful.

Well done, thank you for sharing.

Great Video !! 🤗

Wonderfull teacher actually learn something thanks

Nicely done sir!

Thanks Pete....big help.....

Awesome video, very helpful... thank you..

thanks for the col vids and proof the eye can be accurate

Great video, Mr. Pete. I've heard your second method referred to as, "Using the Mark 1 eyeball." Apparently, yours is in good working order.

woww mr. Pete, you have the eyes of an eagle..

Thanks :) I have been thinking how to do this.

cant wait for the next one!!

Excellent instruction

Top class video thanks
