Thank you, appreciate that!
Have a look at my post, when I measured temps after adjusting the preload. But like I said, I'm no expert, and I don't know how the temperatures differ from the bearings to the housing.

Thanks, my temps are definitely lower.
After the 30 min run I took a .025 cut at 900 rpm (a bit fast for 1.25 diameter stock) The finish was very nice with no trace of chatter or harmonics.
Well the gear experiment was a bust.
@jcdammeyer can Alibre Pro design gears?

If you use F360, would this work for you?

GF Gear Generator | Fusion | Autodesk App Store
A basic gear design application for enthusiasts and professionals alike. With the 11 different variants, you will be able to implement gearing mechanisms into your designs as easy as it gets!

So long as it doesn't require the paid version of F360.
What's wrong with the gear you printed?
The bore is too small and it's too thin to drill it out. So thin that I doubt it would actually hold up.
How did you generate the STL file for it?
I found it on Thingiverse.
I did this gear back in March of 2022 so it's been a while since I played with making gears. It's a python script where you fill in parameters and it generates the gear. I also have the gearotic program written by the guy that designed MAC2/3
The gears worked out quite well as 3D printed.
I don't recall why this Project #42 was put on hold.
I'm on the fence about upgrading to Design Pro but my desire to make patterns and now this has me strongly considering the upgrade.
My free version of 360 has a gear generator in it. Seems to work quite well. It was something you had to add in to the tool kit. I don't remember the details of doing that, it's been well over a year since I did that.
This was for my shaper. The 3D printed version worked quit well but I gave up on the project after realizing the internal thread was a square thread. The plan was to get @Tom O to make it out of brass in on his CNC mill.

Isn't that always the problem. Spend hours figuring it out. Use it for that project. Then a year later barely even remember doing it.
Here's the python code for creating the gear. I'm sure if you go into the Alibre Help forum there will be information for more or different kinds of gears.
Python:
# Gear Generator Script
# Used as a demonstration of how to create a custom utility
# for use with Alibre Design
Units.Current = UnitTypes.Millimeters
# default settings
NumberofTeeth = 20
PitchDiameter = 30
PressureAngle = 20
Thickness = 3
Win = Windows()
ScriptName = 'Gear Generator'
# create dialog window and show to user
Options = []
Options.append([None, WindowsInputTypes.Image, 'GearGenerator.png', 170])
Options.append(['Number of Teeth', WindowsInputTypes.Integer, NumberofTeeth])
Options.append(['Pitch Diameter (mm)', WindowsInputTypes.Real, PitchDiameter])
Options.append(['Pressure Angle', WindowsInputTypes.Real, PressureAngle])
Options.append(['Thickness (mm)', WindowsInputTypes.Real, Thickness])
Values = Win.OptionsDialog(ScriptName, Options, 170)
if Values == None:
sys.exit()
print "Working..."
# get user inputs
NumberofTeeth = Values[1]
PitchDiameter = Values[2]
PressureAngle = Values[3]
Thickness = Values[4]
# get current part
MyPart = CurrentPart()
# get the plane to create the gear on
GearPlane = MyPart.XYPlane
# create the sketch then extrude it
ProfileSketch = MyPart.AddGearNP("Profile", NumberofTeeth, PitchDiameter, PressureAngle, 0, 0, False, GearPlane)
Gear = MyPart.AddExtrudeBoss("Gear", ProfileSketch, Thickness, False)
print "Done"
