Project Information

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.

Next to last gear layout.

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

Download the program called : Gear Generator It's free and gives you the ability to create gears of all sizes, chains design to run on the gears, gears on gears (limit 2), rack and pinion gears, etc. You can make everything i do using it and be creative too.

I have actually bought that bit of software and have used it extensively…

My problem is that I'm not great with new ideas but get inspiration elsewhere and then run with that.

That is why I was asking if you had a diagram that has already worked out the gearing layout.

Sorry the only thing I have is the picture. I knew what the size of the backboard had to be for the width of the door, then pretty much started using the gear generator program to start designing gears. I started with the largest gear my printer could handle which was 8-1/2" diameter. Positioned that as the starting point and then started making gears that were smaller and smaller until I got the layout I wanted. The original idea was to have the setup be identical on both sides of the back board because I wanted to make vertical rods going up and down on each side like a bank vault door. Because it's a sliding barn door type door, I scrapped that idea and just used the gears to lift a hook style catch on the right side of the door only. Pretty much was a spur of the moment design (unlike most of my stuff that I blue print before starting anything). I'm adding a close-up of the hook that I didn't put on the post


Sorry that's all I have right now. The last couple projects I just kinda winged it. Not like me but Covid has given me the time to just be creative and not so anal.
