There will probably be comments on these techniques and they are appreciated by myself and the rest of the viewers. So chime in if you have some ideas that would improve the process of making gear blanks.

Especially since we will bore anyway.

Please SUBSCRIBE 🔔 We have developed useful content to help the machinist community with gears and mechanisms. With our free resources centered around skills/tools/knowledge, you are now enabled to make any high quality gear you would ever need. Gears are at the heart of all interesting mechanisms.
The history of gears is surprisingly interesting - the process of milling and hobbing gears plus the transmission of torque and movement all find a place here. We will open the "Secret Gear Case" to YT as well through this channel - a personal mission
