Decided to get the dust off the scrollsaw and cut some gears. Always thought a bank vault door gear setup looked neat so I though Id make a lock setup for the furnace room / storage room in the basement door. Grandkids love it. Gears are cut from a combination of 1/2 & 1/4” Baltic Birch and 1/2” MDF. All in all with the changes made along the way and 'screwups', I cut 280 gear teeth for this.https://www.lumberjocks.com/assets/pictures/projects/2283341-97x65.jpg?1602118955Next to last gear layout.https://www.lumberjocks.com/assets/pictures/projects/2283342-97x65.jpg?1602118970
Final installation on the furnace room / storage room door. Clockwise turning of the wheel causes the latch hook on the right side to lift from the lock pin assembly. Counterclockwise it re-locks the door again.In the event my wife needs to get in the storage room, she can just lift the locking hook (it's on a friction bolt) rather than turn the handle.
Enjoy.. POP
