Brilliant demonstration of the method described in Ivan Law’s book. I’m just about to try it on my Myford Super 7 lathe, with the Myford dividing attachment . . . . Kind regards, Steve A.

Hi, is this method also good to do small bevel gears? Example: daa= 13mm and M0.8 cutter? Thank you

@@prof-rieg I'm strugling with this formulas... Can you help? The question is i need a bevel gear for 2 shafts at 90º transmission. I found at Aliexpress a bevel gear that is advertised as 15T M0.8. And here starts the problem. By the formula you use "d" should be 12mm (0.8x15=12), but is not. Also "dai" by formula should be 13.13mm, but is only 8.41mm. Also "daa" should be 20.13mm (for "b=3mm), but is only 13.13mm. What am i missing? I bought from Aliexpress this bevel gear and they work very smooth, but unfortunately they are not hardened and i would like to do by my own same gears and then do some heat treatment to make them hard. I already tried but i can't make them so smooth as the original one. At Aliexpress the seller have a draw. If you could take a look and give some help i would aprecciate a lot. Here is the link to the bevel gears: www.aliexpress.com/item/1005005119203188.html?spm=a2g0o.cart.0.0.55bc38daDI7KNO&mp=1 Thank you for your attention and also for this great lesson!

@@prof-rieg Hi again, it seems not... I did an experiment with all this formulas you presented. I put them on an Excell sheet in order to get the results you show. It worked fine and now i only need to play with "m", "z" and "b" parameters from your draw. In this way i can get a general view of all gear and the relation between measurements and how they behave when you change one of those parameters. Very usefull to draw a gear respecting this math. But now and for the gear i need, with "z"=15 theeth, "m"=0.8 and "b"=3mm i get a result for "dai"=13.1mm and "daa"=19.1mm. And here is the problem! Because the gear i need must have "daa"=13,1mm and "dai"=8.4mm. This means if i use this method to cut this gears it will not work. The gear i need is sold at aliexpress and i bought 1 pair. They have a precise fit and run very smooth, but the problem is, they are not hardened, so i need to do by myself this gears. You can see at aliexpress this gear where ths is also the corresponding draw. This is the link: www.aliexpress.com/item/1005005119203188.html?spm=a2g0o.cart.0.0.391138dakGBFy6&mp=1. Now i gess there is another way to cut this small gears. I saw at youtube some people cuting bevel gears using diferent angles. It seems they use complementary angles. They cut the piece on lathe with one angle and then use a diferent angle on milling machine. Example: on lathe cut 48º21´ and on milling machine 41º18´. The total angle is 89º39´ very near the 90º and seems to work very well. So, i would like your help if possible, about this method of cut bevel gears using complementary angles for gears with sizes out of those rules you offer. Do you know how this process work? How to calculate the best complementary angle? What is the math behind this method? Thank you a lot and have a nice day

I too prefer the sound of the machine some of the other comments I don't even know where to begin other than somebody didn't have anything better to do human beings are a petty worthless lot to begin with those with the least intelligence or the most intelligence often make the most trouble especially if they have no practical experience. Sometimes it's best to know only enough to be motivated and productive that's where the most fun can be found. Learning comes from making it over because of some minor detail you are not aware of and therefore overlooked.

Can't the crap music, I'd rather hear the machine like any machinist would comment; this says most about what is happening!

Music, loosely called, is atrocious! Very distracting, even hateful.
