I am having trouble getting some small 48 pitch gears to come out nice. I am no expert by any means, and just fooling around - but the fact that my gears do not seem to be perfect is really getting to me.
I have spent about a year messing around a few hours here and there!
I have a small lathe .. have been able to turn out perfectly concentric stock to then mount in the rotary table/dividing head setup I have on a small mill.
From here it gets weird. I have dialed everything in with a test indicator, swept back and forth, etc.
The gears always seem to come out with either too shallow of teeth, teeth that get slightly wider at one end, or slightly deeper teeth on one side from the other. All of this causes them to run a little rough or with tight spots when setup.
Am I overthinking it? The gears are used in a differential i`m making for a robot - so the spacing between them is pre-determined by their pitch circle distance using charts from machinerys handbook. In the end, i haven`t turned out a gear large or small that looks great all the way around.
If I could find cheap 48 pitch gear stock i`d just buy it and move on.
