Designing a prototype for future manufacturing. I have referenced 4-5 different formula pamphlets etc. over the last week or so on Spur Gear design and ratio calculations. I have made an Excel spread sheet with the pertaining formulas embedded in the cells for personal improvement of understanding and future simplicity, yet have no way of verifying formulas etc.
- I'm looking for some help with comprehending the formulas.
- Looking for some (known) values of existing spur gears so I can (verify) my own knowledge of the formulas against them.

Is there someone willing to spend some time working with me on this?

Thank you for your help. Small Bio
