->A much higher complexity level
->Requires more time
->Requires more esoteric building materials
->Much harder to circumvent/guess
->User changeable code
This instructable will take you through constructing a wooden dial combination lock. This particular lock will in fact be used to secure a minibar fridge (replacing the one I have already built) due to some issues with the misappropriation of foodstuffs at my workplace.
This is a moderately complex project that can be completed inside of 9 hours if you move quickly and don't make any major mistakes. Workpeice precision is a must in this project, and you should assure that you have access to some moderately precise tooling.
During the course of this project you will also be creating the dial in virtual format using openoffice (marking it by hand would be a disaster) and then printing it to transfer it permanently to the dials on the finished product.
Openoffice with fontwork installed
3/4 inch pine
1/2" internal diameter compression type spring
Nail gun nails
Step 1: Initial prep
Cut the following pieces:
3 9x12" boards
2 3x12" boards
1 3x32" board
9 3,1/2" disks
4 2,1/2" dowel
2 5" dowel
