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).
Step 2: Making the loop
If you mess it up, no big deal.... just cut it off and try again. (You have 10 of tape measure to work with!)
Wrap the joint in electrical tape (ours just happened to be green).
