I found this (picture) when winterizing this fall. I managed to get the wheel to stay in the window track enough to close it tight. Regardless, I'm wondering what my fix is. The entire window seems riveted together. Do I get a whole new mechanism and drill out the rivets and replace it?
I could also drill out the post and 3D print a new wheel. Then size an appropriate screw/nut and fix it that way.
Leaning toward the 3D printing, but it's all packed away for winter, so I can't get any measurements. Maybe I should have the mechanism on-hand and fix it quick in the spring. Then I'll have time to design/print the wheels for "the next time".
Thoughts?
Is it a common failure?
