Thank you.

I do not understand your comment.

Thanks

You're welcome. :D

Hello! Yes!!

Hi, 16 holes in 20-division plate

Hello If your dividing head has the standard 40:1 ratio, then for 50 holes you must apply the formula: m = 40/50 and simplifying it is: m = 4/5 Now you must multiply the numerator and denominator by the same number until you get in the denominator a number equal to the number you have in your discs with drilled holes. If for example you have a disk containing a circle of 20 holes, then you must multiply 4 by 4 in the numerator and 5 by 4 in the denominator, thus obtaining m = 16 / 20, which means that you must place yourself in the circle of 20 holes of the dividing head disk and open the arm sector 16 holes. This means that you do not make a complete turn of the crank handle but a small section.

Hello friend, thank you very much for your comment.

Thanks. Greetings from Colombia

You are welcome!

Thanks for the good comment.

Hi, I have a video with the theoretical part of your recuest. I hope to translate it into English very soon.

@@easymetalworking ok

Hello! You should use a milling machine and a boring head for mill.

Thanks

you're welcome

well, it took a little research

Hi, I have that information but in Spanish. - for helical gears: www.metalmecanica-facil.mahtg.com/calculo-de-engranajes-cilindricos-helicoidales-sistema-milimetrico/ - for differential indexing: www.metalmecanica-facil.mahtg.com/division-diferencial-en-el-divisor-universal/ I hope that it can help you.

If any part of the video worked for you that's fine.

Thanks.

you're welcome

¡¡¡que bruto!!!

Well, try later.

Thanks.

You are right, this topic is simply to show an easy way to directly convert millimeters to known fractions of inches.

USA uses both metric and inches. If I had to buy a part from Europe but the measure was in inch/fraction I would need to convert to get the right size part. That is exactly why I watched this vid. Math is fundamental the more skills you have the better engineer you will be.

Thanks

Please explain how it become 64 I didn't understand It´s simple, you take the number 12.7 and it you must multiply by the 5.03937 constant, so then you obtain 63.999999 a value that it´s practicly equal to 64.0 by aproximation.

@@easymetalworking okay but what if you multiply 10mm by 5.03937, it doesnt give a number that you can just round up??

in that case, you should round down, that is 50

Hi, this is not my voice, it´s a robotic voice, and I used it, because I don´t speak english. I hope that you can understand me, and I´m sorry if I was bothered whit this.

sorry im wrong bro.i dont understand why i said that..lol im shock,. just multiply it by 2.like 2*2=4*2=8*2=16*2=32*2=64*2=128.

Really, the constant is 5.03937 / 128, a value in inches If this fraction is divided, that is, the numerator against the denominator, the result is 0.03937 in. which is the equivalent of 1 millimeter. Now, if you have a value in millimeters and if you multiply by 1, nothing happens, the value in millimeters does not change. What I do in my method is multiply a value in millimeters by a special 1. This special value is a fraction that is in inches (5.03937 / 128). With this I get a fraction in inches. The value 5.03937 came from looking for a number that fulfilled a condition: Find a number that is equivalent to 1 mm. in inches (0,03937) and that at the same time has the denominator 128: With what is a simple equation: 0.03937 = X / 128, if X is cleared, then: 128 (0.03937) = X solving: 5.03937.

@@easymetalworking I hope you read this and help me to convert 5/16-18 inch to millimeters

5/16-18 is equal to 7,93 mm. 1,41 mm. Pitch.
