minor nitpick: solid support is not the best choice of words here because it can be interpreted as referring to solid geometry, I would say stable support instead

Yes, a STABLE support and not from the solid.

All,
Thank you for all the help. Here is a summary of what I have learned and the changes I made as a result of your help.
  • Attach sketches to the part reference planes or Datum Planes, not to faces.
  • Instead of starting with an Involute Gear, start with a Part, then a Body, then an Involute Gear
I have attached the improved file. Note to change the size, all you need to do is change the number of teeth in the Involute Gear and recompute the Body. I have done this for values of 18 (default) and 14. Caution other values may break it.
All the other calculations are done automatically in the Spreadsheet.
I have renamed the parts and sketches to make it easier to see what I did.
I have attached the file for your enjoyment.
Tom

Small correction: If a Part contains nothing but a single object, it is useless. You can just start with directly with the body.

Looking at CrossBox-sketch:
- having less dimensions in favor of geometric constraints means less clutter on the screen and makes you often think more and better about the geometry.
- to center a rectangle I recommend to keep all horizontal and vertical constraints and add a single diagonal symmetry.

(You could even omit the construction rectangle completely, but using it could be sensible for the sake of clarity.)
