i just lucked into my solution to making gear templates

i just lucked into my solution to making gear templates. i was watching a video on the ETC news channel on youtube this when at the end they pointed their viewers that were interested to a video of a marble music machine built by hand by Martin Molin  also mentioning that he documented the entire process. the process documentation was the key as i clicked on a related video of him making the wooden gears. this video happened to have a link in the description to the program he used to make the designs which is something i have been looking for separate from a CAD program as i needed one dedicated to gears alone. there is the online version and the program version.
