Unfortunately no one seems to have the involute gear cutter I need to cut some change gears for my lathe. I'm looking for a #6(42 and 40 teeth) 20 degree / 16 DP involute cutter.

I assume you tried Ali. Not the best quality cutters but they work.

I have a set of 20° Module 1.25 gear cutters. That's about a DP of 20 too. But the difference between 16 and 20 is very hard to see. How do you know yours is 16?

I ask because I had a bitch of a time figuring it out and in the end, I flipped a coin and ordered praying I would be right. I was cuz they matched all my current gears.

I could loan you the cutter you need if it turns out it's really a 20......

I can't find my old post from many years back where I made my calculation based on the gears already on my lathe. Maybe that post isn't even in the archives any more? In any case the gist of it went something like this. I reformulated the standard equations so that I could use the largest of the gear dimensions in order to reduce error in the calcs. This means using the outside diameter so that P=(N+2)/D where:
D= outside diameter
P= pitch
N= number of teeth

In my case my existing gear has 50 teeth and an outside dia of 3.25 inches therefore P=(N+2)/D=16. Works beautifully if measurements are based on a precision gear but if the measurements are made on a poorly made gear then the calcs amount to the proverbial garbage in garbage out phenomenon.

There are a number of websites that have tooth templates on them. I matched to those using a gear I had. It isn't much better than your method which didn't work for me very well either. I ordered 20s from Ali figuring I would just keep them if the 20 was wrong and then order the 16s. Based on an actual cutter tooth fit, my gears were indeed 20. So it was a good gamble.

Unless it got caught in a crash, your post should still be there. But ya, it can be a bitch to find old posts. @YYCHM does seem to have a knack though.

According to Google to convert diametral pitch to module divide 25.4 by diametral pitch to get the module. So in my case 25.4/16=1.5875. So my question is would 1.5 module cutters be close enough to 1.5875???

Yes they will be "close enough". These are change gears, right? So that last few tenths isn't doing anything for you. Just make sure theres enough play beween gear teeth and they will work perfectly.

Yup. And considering the errors we all make measuring gears, it might actually be better.

Personally, I think the best test is how well the new cutters fit an old gear. If the new cutter fits like it made the old gear, be happy!
