Is your Dad a member of TechShop? Maybe he works for the big blue oval (if he does, you know what I mean), or maybe some other company the uses security badges?
Here is a great gift for Dad... Make him a retractable badge holder that he can actually use! Who doesn't need a tape measure from time to time?
Tools: (all available at TechShop)
Bench grinder with wire wheel
As with all Instructables, read ALL of the instructions first, before starting your project.
Step 1: Modify the tape measure
Clip off the end with a pair of shears or scissors.
We will be making a loop to hold the keychain, so in order for the spot welder to work, use a wire wheel on a bench grinder to remove all of the paint in the areas of contact (spot welders work by making electrical contact).
