Hey Joe, your super troll has called this video a hoax and claimed it has over 70 operations as shown. I watched it a bunch of times and can't see where that number comes from. Care to comment?
With pleasure. First, super trolls, regular trolls, average trolls, below average trolls, or the lowest life forms online....Maggots, don't deserve a reply. Or any type of attention for that matter. I'm not sure what universe my secret admirer is living in, but 70 operations is a bit exaggerated. Perhaps its an unconscious demonstration of their inability to count. Who knows? I had actually forgotten about my maggot admirer, but do appreciate them watching my channel. Thanks for the heads up. I needed a laugh. By the way, to anyone reading this.....if anybody can count 70 operations to complete this demo part, please let me know how you arrived at that number.

Hey Joe, i am a certified electronics technician holding a degree in Electronics Engineering Technology. In my field, it is a must to know trig functions. We use the sine of 45 deg. Very often, because the rms value (voltage in your shop) is .70711 x peak. However, i have always been interested in machining and spent as much time as possible in the shop with some very good machinests. Since retiring, i now spend a lot of time in my small home shop working with my mini lathe and mini milling machine. Thank you for all your great info. I use it often and you are truly a blessing to me.
If your stock is longer, you can turn a reduced diameter (inscribed circle to the finished square) on one end so you just touch this diameter region when the square is finished. If the finished piece is a rectangle, turn 2 diameters, each determining 2 opposite sides. Saves trig, saves a lot is you have no readout.
hi Joe, you among others have inspired me to go to college at 41 to do a diploma in advanced mechanical engineering. I could've just learned the basic machining but instead opted for learning the theory too, including the physics, maths and electrical. thanks and get well soon

As a general rule. My go to end mill is a .375 3 flute carbide.. my machine does most of its work with that size(unless bulk removal is in order, or smaller is required) so you using your preferred size instead of a bigger one is perfectly understandable.
Always wanted to be a machinist, got to be a salesman, and later a steel fabricator, instead. I envy your wonderful knowledge and skill, and thanks for lesson. I'm 82 and going to buy a mill unit.
I've had lathes and mills for about 28 years now to do my own equipment repairs and every time I watch Joe I learn something new. I really enjoy watching your videos sir.
Been using this method for a number of years now. It actually came about as a result of the cost of square shaped stock in some of the harder materials I generally work with being needed in larger sizes. Being that most of my work is in a larger 50 taper machine, I will also go as far as dovetailing the grip rail in heavier pieces (500-800 pound) to make sure they stay put. I even go as far as cutting the grip rail in the 12 foot lengths before they go in the rack on certain materials just so they are ready to go when needed. Glad to see someone else had the same idea and is able to share it with others!
Hint: Pythagorean theorem. The magic factor is 1/√2. 30°, 45°, and 60° angles all have simple formulas for sine, cosine, and tangent, and it's worthwhile committing them to memory. They were pounded into me in 8th and 9th grade and stick ever since. tan 45° = 1 sin 45° = cos 45° = 1/√2 sin 30° = cos 60° = ½ cos 30° = sin 60° = √3/2 tan 30° = 1/√3 tan 60° = √3

Your videos on different techniques are all awesome, but I particularly like the ones on setup tricks like this.

Hi there. Yeah Keith from Michigan. What a kicking process from round stock to square. I primarily round material for the Lathe projects. The ability to change via to square, great Joe 👍..
This brings me back full circle to the first Joe Pie video I ever watched, the "the best mill tip you'll ever get" on squaring stock. I've used that tip countless times, but until now, hadn't made the connection to how it could be used on non-square'ish stock. Thanks for another informative video.
My heart breaks for the Ukrainian people. I'm limping around with a busted foot but have no room to complain by comparison. We are all truly blessed. Thanks for checking in.
It's pythagorus - hypotonus squared equals sum of the squares of the other two sides. Using the diagram shown near the start of the vid, the diameter of the stock is the hypotonus, and each side of the required square bar will be the other two sides. Make each side equal 1 unit, then the diameter will be the square root of 1 squared + 1 squared units. Which equals the square root of 2 = approx (1.414) So dividing the diameter by 1.414 will give you the size of each side of the square. Or instead of dividing, multiply by the reciprocal of 1.414 (mathematicall the same operation) which is 0.707. Or you can multiply by either the cos or sin of 45 degrees (both are .707, because both adjacent and opposite sides are the same length, and cos and sin of 45 deg can also be derived by pythagorus in the same way).
In your diagram, the diameter of the stock is also the hypotenuse of the triangle. If you assume the length of the sides are 1 unit (inch, mm, mile, furlong - doesn't matter), then the length of the hypotenuse is the square root of the sum of the squares of the sides - 1 squared is 1, so the hypotenuse is the square root of 2, or roughly 1.41428 units long. Flipping this on its head, if the hypotenuse is 1 unit long, the sum of the squares of the sides is 1. The square root of 1 is 1, so the squares of the sides are each 1/2 unit long. This means that the sides are the square root of 1/2, or 0.70711
Correct. The hypotenuse will always be the round stock diameter. Also, There are several ways to calculate the max square size. I though just cutting to the end and presenting the most useful value would be the easiest to remember.
Excellent video/information! This has became the go-to channel on YT for machining tips & tricks- Hope you continue on the mend & are 100% soon. This is the kind of video that is worth rewatching several times. Thanks again!

Great trick! Thanks for sharing. I hope your recovery is going well, and you are back to 100% asap. Also, I used another trick of yours the other day and it worked flawlessly. The one you showed about picking up an internal thread on the lathe where you but your tool into the thread with the boring bar loose, then use an indicator on the the end of the shank to see how much it moves so you can put your tool right in the correct spot. So slick, this was a large specialty nut for a valve where I work, with a buggered up thread on the end. Worked great, thanks for sharing all your knowledge!!
I've been using grip stock in all sorts of operations since your earlier vid about it, this is another useful addition to the armoury, like the earlier tip about five-face squaring in a single setup that I now use all the time. Pure gold and a bonus break-edge tip as well. Useful as always.
Superb,the grip rail seems like common sense itself... now you've pointed it out.😅 Cheers Joe,brilliant tutorial as always,helped me so much in my baby steps into machining.Many thanks sir,& wishing you a speedy recovery!🏆
Love it when you show techniques like this, it's brain food for me. Or another slice of Pie 😁 Take it easy with the leg. It may be 6 weeks but if you push that tendon will pop. No consolation but the wife's still got her foot up too and she only has half your troubles. Best wishes Neil
Thanks Joe, been doing this most of my life, never saw this technique before, but it makes good sense. I've got one year of "machine shop" education, everything else learned by the seat of my pants. Quite often a logical tool path can greatly reduce times of work handling. Very well demonstrated.
Once again a great work holding tip - thank you. Some useful triangles for angles and proportion, thanks to old pythagoras: 1-1-sqrt(2) 45 deg this exmpl 1-2-sqrt(3) 30/60 deg 3-4-5 90 deg the old favourite 5-12-13 90 deg tricky spots!
Alternative: It's square root of 2 divided by 2. Length of the cube side = a. Diameter of the round stock = D. So a² + a² = D² 2 * a² = D² a² = 1/2 * D² a = sqr(1/2) * sqr(D²) = sqr(1/2) * D = 0.7071 * D
I love this channel! I always learn something new or at the very least learn a better order of operations. Thank you Joe, your knowledge it is invaluable!👍👍
Great tip Joe. I thought about doing something like that some time ago, but I got cold feet and did it the conventional way. Wishing would a continued speedy recovery
Always great to watch! think its great you are passing on all these trade tips. I always have a smile on my face as I learnt so many of these things off the older tradesman while I was an apprentice and young toolmaker. Keep up the wonderful work! I hope your videos inspire more people to take up machining as a hobby and also keep the manual skills alive in the trade. As a model engineer building live steam models I'm always referring fellow hobbyists to your videos, thanks for providing a great resource Joe!
Talk about going off at a tangent! Yes Diameter x .707 ... knew there was something of the Jas Bond about it - - all these 7's and 0's but the Man with the 'Golden Gun' - just spot on the target, just has to be: .... our Joe. Thanks for that tip - 3 or 5 sides at once included.
I just use .707. Unless I use 1.414. But another magic number for the machinist is 0.866 (sine cosine 30 degrees). I use it for making hexagons. Also multiplied by a diameter it is the distance between jaws of a three jaw chuck.
Great videos as always Joe, was wondering if you think you could do a specific video request in the future. Id love to see your take on making precision located holes using spot drills versus center drills and maybe explain the best practices to actually make a precision located hole using a drill bit or what it would take to make a precision hole if drill bit or spot drilling is not sufficient a little metrology would be awesome to see the difference between all methods including probably your methods. There are very few videos on youtube demonstrating good techniques on precision hole locations that i can find. Appreciate you and the time you put into sharing your experience.
The trick to finding the largest square is that a 45-45-90 degree triangle has a known relationship between the hypotenuse and the two identical legs. The hypotenuse is the length of a leg times the square root of 2. So by using the diameter as your hypotenuse you just have to solve for a leg and that's where you can either divide by the square root of 2 or multiply by .70711 (relationship/ratio between a leg and the hypotenuse). I hope someone finds this explanation of the math behind this useful.
That was cool, and it totally makes sense mathematically. I like the shortcut trick for handling the part less too. Hope you're back to feeling good soon.
It's both the sine and cosine of 45 degrees. :D Like knowing pi out to five places, knowing co/sine of 45 out to five places (like you've got there) is just one of those things we wind up memorizing because it's so handy. :D
@@DiffEQ Can you please share with us a picture of your mill that will repeatibly hold tolerances better than 1 part in 100,000 ? (and your temperature controlled workshop)
Came here to say this. I have a plumber friend that always uses 1.41 x a distance between two points. Or 1.5 to be safe. He uses this to get a total length of pipe between those two point but running it one leg, then a 90 and the second leg. Again just a trig function because the hypothesis on a 45 degree iso triangle in relation to the other sides.

I hope your videos inspire more people to take up machining as a hobby and also keep the manual skills alive in the trade. As a model engineer building live steam models I'm always referring fellow hobbyists to your videos, thanks for providing a great resource Joe!
I appreciate the trust and referrals. Thank you.
Also can be defined as diameter divided by square root of 2
Very nice JP, thanks for the info.
Talk about going off at a tangent! Yes Diameter x .707 ... knew there was something of the Jas Bond about it - - all these 7's and 0's but the Man with the 'Golden Gun' - just spot on the target, just has to be: .... our Joe. Thanks for that tip - 3 or 5 sides at once included.
I just wanted to say thank you! I really appreciate you sharing your experience!
Another interesting and entertaining video. Thanks Joe!
I just use .707. Unless I use 1.414. But another magic number for the machinist is 0.866 (sine cosine 30 degrees). I use it for making hexagons. Also multiplied by a diameter it is the distance between jaws of a three jaw chuck.
Hex size across the flats X 1.155 for round stock required.
Hey Joe. Thanks for this useful tidbit for sure. It is a keeper need to know thing. Indeed !
Thanks for checking in.
@@joepie221 You are a master of time management and accuracy my friend.
Your great. Tks!! You always show us the tricks to improve our work. Can't think you enough!
Happy to help!
Great videos as always Joe, was wondering if you think you could do a specific video request in the future. Id love to see your take on making precision located holes using spot drills versus center drills and maybe explain the best practices to actually make a precision located hole using a drill bit or what it would take to make a precision hole if drill bit or spot drilling is not sufficient a little metrology would be awesome to see the difference between all methods including probably your methods. There are very few videos on youtube demonstrating good techniques on precision hole locations that i can find. Appreciate you and the time you put into sharing your experience.
Oh gosh, you could go hog wild with that and do a setup with machinist's buttons.
I was gifted a set of them, but I've never actually used them.
Thanks Joe. I have a project coming up where I need to make a square bar out of some round stock so this has saved me a ton of work. Thankyou Sir!
Glad to help.
The trick to finding the largest square is that a 45-45-90 degree triangle has a known relationship between the hypotenuse and the two identical legs. The hypotenuse is the length of a leg times the square root of 2. So by using the diameter as your hypotenuse you just have to solve for a leg and that's where you can either divide by the square root of 2 or multiply by .70711 (relationship/ratio between a leg and the hypotenuse).
I hope someone finds this explanation of the math behind this useful.
That works, in my head it was multiply by sqrt(0.5) which also gives the same answer.😊
omg i just want to mill and cut stuff do i have to know all this lol?
@@NewsNowFortWorth nah, just crank the rpm and make some chips
Very Smart and quick way of doing this. Thanks for sharing, Joe!
Great tip....positively Joe. Hope you continue to mend faster than planned!
I hope so too! Thanks.
Another good teaching piece. Thanks Joe. Hope your foot gets better.
Thanks very explaining the tip to avoid burrs!! Good luck from Spain!!
Thanks Guys.
Ah yes.Another arrow for the quiver.😃Always something to learn.Thanks,Joe.
Thanks so much Joe, hope you are healing well! take care bud.
I'm almost half way there. Its a slow road.
Thanks Joe, clever as always.
Great tip Joe. I have a project I am working on and will give this a try. Thanks get well soon.
Good luck.
Hey Joe, Good to hear your voice. Great tip I will use this technique a lot thank you sir. Be Safe
Hi David, thanks for checking in.
Thanks I always learn something from your videos
Great tip as usual. You need to write a book of machining tips and tricks, I'd buy it.
Maybe one day!
Another Gem! Thanks for the Tip!
Genius Joe. Thanks.
Outstanding Joe! Thanks for improving my knowledge base.
That was cool, and it totally makes sense mathematically. I like the shortcut trick for handling the part less too. Hope you're back to feeling good soon.
Thanks. Its a good tip to at least see once.
Awesome technique Joe, thank you!
Great job sir, this is real industrial thinking sir thumbs up
Cool trick. I usually used a saw to cut lots of material off.
In where I live we have LOTS of rounds stuff, but hardly any square stuff.
A the unit circle; such power and simplicity
Geometry makes things easy.
Perfect timing Professor Joe! I was just pondering this exact thing.
Perfect!
Cheers for the tips! Hope the leg gets better soon.
It's both the sine and cosine of 45 degrees. :D Like knowing pi out to five places, knowing co/sine of 45 out to five places (like you've got there) is just one of those things we wind up memorizing because it's so handy. :D
i know. Joe said "a function of 45 deg" he could have literally guessed either sin or cos and he would have still been correct!
Or half the square root of 2, though the 5 decimal olaces is a bit reckless.
@@olderasdirt Reckless??? I'm not sure you understand the meaning of that word.
@@DiffEQ Can you please share with us a picture of your mill that will repeatibly hold tolerances better than 1 part in 100,000 ? (and your temperature controlled workshop)
Came here to say this. I have a plumber friend that always uses 1.41 x a distance between two points. Or 1.5 to be safe. He uses this to get a total length of pipe between those two point but running it one leg, then a 90 and the second leg. Again just a trig function because the hypothesis on a 45 degree iso triangle in relation to the other sides.
Reciprocal of the square root of 2 - electrical a.c. to d.c. conversion
It is actually the sin or cos take.your.pick of 45
Yep. Pythagoras.
A^2 + B^2 = C^2
A=B on a 45° triangle
2A^2 = C^2
A√2=C
C=A/√2
Great tip, thanks for sharing.
Triangles never lie unlike parents squares and um "other" polygons
Tat is a great little shop gem...
