Machining Round Stock to Square -- A Time Saving Technique !!! 

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.

@@joepie221 Well said my friend!!!

Probably counting footsteps, breaths that he takes, pressing the on and off buttons etc. Clearly someone hasn't got much else to do. :)

@@joepie221 If I lose count, I just add six for good measure. I lost count of how many times I lost count. (Does that make it exponential?)

@@joepie221 I reckon I know what he's applying 70 operations to but he didn't need to come here to be abused - he could have stayed at home - and abused himself! 🤣🤣🤣

Thats good to hear. Knowing how parts are made does make an engineer better. I know the guys on the floor notice.

Thank you very much. I believe we can all learn something new from each other.

Good luck.

Its good to use the material on the shelf if you can.

My pleasure.

@@joepie221 My benefit. I think I'm getting the better end of the deal. ;-)

Welcome. I hope you'll hit that sub button.

Someday I'll show how to plug a square hole with a round plug. It can be done.

Thanks. I'm on the mend.

Thank you.

Glad you like them.

If only for a moment. I have a bunch of mini machines to complete and a beautiful Stuart vertical twin. I have to get better.

I'm faking it. I have a long way to go to be back.

Thanks. When needed, its a real time saver.

Thanks Neil. Unless I want to scuba dive in circles for the rest of my life, I'll do exactly what the doctor says. Its coming along well.

If a spot is that tricky, it’s time for a DFM review.

@@Amerikanin2numarali_ustasi Thank you - VG

@@troglokev No Manufacturing ... Just playing!

@@crjpetersutube yup you the only one who can manufacture we all are players of VG

Thanks for checking in.

@@joepie221 You are a master of time management and accuracy my friend.

I appreciate the trust and referrals. Thank you.

Thank you.

Thanks very explaining the tip to avoid burrs!! Good luck from Spain!!

Thanks Guys.

Hi David, thanks for checking in.

Hi Bear. Nice to see you drop by. Best wishes to you and the misses for a smooth treatment.

Not looking goog Mr Joe. The cancer is like a CA Wild Fire, hopes are to put it out, but as of today, no looking good. We leave in in His Hands now!

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

Mission accomplished :)

Thank you, I will

Cheers back at ya from Austin Texas.

Its a drive by. Not 100% yet.

Thank you.

OOPS !!

Correct, but a symmetrical offset initially would then yield a grip rail with uneven side heights and increase the potential for it to jump out during later cutting operations.

.70711 is just easier to remember.

Glad you enjoyed it

Thanks for watching!

Every time the machine is on you should pay attention.

Three points of contact. Text book work holding. No need for a v-block.

awready then

Imagine this part 24" long with irregular ends.

@@joepie221 24" wide vice needed then :) Great vids, I learn a lot....Thanks

You bet.

Thanks Chuck.

It felt good to cut something other than a bagel. :)

3d printed soft jaws is the future. Why tie up a $50k machine when a $120 will do.

If I put all caps in the title, the video will be on something that will keep the viewers from injury.

@@joepie221 Emphasis where worthwhile, as it should be :)

CNC, servo/stepper drive rotary indexer or very creative manual setup.

The grip rail can be off center a bit and not hurt the final position, but if the net/net is close, indicate the material once you flip it over and use the grip rail.

sin 45° too :) I once had a friend ask me (during a dinner) what the distance the throw would be from third base to first. I said...."well...take the distance from base to base and divide by .707" His jaw dropped lol and he asked how the heck would I know that.....basic trig! There are definitely trig tables (charts) and there is one in the Machinery's Handbook if I recall correctly.

I milled the one face just shy of truly tangent to show the result. It was .007 away from a true corner. This would have been the biggest square possible from that blank.

@@joepie221 thank you

Than you have to blend the original 2 sides. I'm not a fan of that.

0.70711 is half the square root of two - try your metric calculator on that 9-)

yes, since 0.70711 is a decimal value of 1/√2. This is taken from the special trangles method in math which is irrespective of measurement, where there's 3 angles. One 90 and two 45s, so the hypotenuse is √2 and each side length is 1; that's the special triangle. Knowing this, we use Sin(opposite/hypoteneuse)=angle so we find the hypotenuse; 1/√2. That's why, some nerd shit, but useful!

It's a pure number, unitless. So it works on all units

Yep.

As shown.

@@joepie221 yes. The students who struggle with trig respond well to this choice of words. Just trying to help other viewers/hobby machinists.

I like the brown ones best.

@@joepie221 they're all out there. The Darwin awards club are giving certificates in cereal packets. And what's worse is they breed. Regards from Canada's banana belt. 🤔🇺🇲🕊️🇺🇦🍌🇨🇦👍🐒🐒

It depends on the material your milling. 2 flute endmills are usually used for softer and gummy materials like aluminum, brass, plastics, copper, etc. 2 flutes allow the cutter time to clear a chip otherwise the chips pack up in the endmill and cold weld to it which causes all kinds of problems.

Softer the material = the fewer flutes you need + higher RPM, harder the material = the more flute you should use and lower RPM.

sin(45)*diameter = cos(45)*diameter so go ahead and choose for yourself.

You keep the monel. I've done my time with that material.

Not if it's steel. It looks to me that it might be a hydraulic cylinder gland.

It looks like one, but its a drop from another job I ran.

Love that punch line.

Make the square first then nest the part in a V block and remove the corners.

I can plug a square hole with a round plug. Yep, I said that.

@@joepie221 I had no doubt! Keep up the good work! I think I'm learning something! Woody

Also known as 1/(SQR (2))

Toe mato, toe mayto......

Knowing why is just as important as knowing how. Keep an open mind and always listen to the FOG's.

@@joepie221 I want to build my own mini 4 stroke engine so definitely need the know how I've already done much research. sorta on a time crunch because of cancer... not imminently terminal as its controllable with chemo. Also 70711 is now imprinted on my brain

@@joepie221 fog?

@@NewsNowFortWorth f*** old guys

@@NewsNowFortWorth Fu#king Old Guys

Thanks Paul.

Correct.

@@joepie221 Which reminds me: as much as you love to teach trig, you ought to do a collaboration with 3blue1brown. He does some wonderful math videos. Maybe Ruger could get some animation time with the pi brothers 😁

Bang for the buck 3/8 or 1/2 depending whats on sale.

Hex size across the flats X 1.155 for round stock required.

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

I agree, it was quicker too, and more importantly, it was SHINIER! 😜

That was funny.

👌

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.

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.

Good luck.

I've seen the dovetail grip rail used with success on some very heavy stock. It has great grip integrity.

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.

Good luck Harold. Thanks for the purchase.
