In this instructables I will show you how to turn an ordinary flat screwdriver into spanner slotted screwdriver, with a file(tool).
Step 1: The Idea
The idea for this mini project came with the need of a very unusual type of screwdriver.
Just the other day, I had to repair a child proof power-strip.The plastic covers for the holes were broken,the spring mechanism was also damaged ,but if I can take those out, I can normally use it ,like a regular power-strip.
When I wanted to disassemble it,I saw that very unusual screw. After looking up in Google,I identified it ,as spanner slotted screw-head (correct me,if I am wrong ,I am not 100% sure). I seen once this type of screw on a battery charging unit,it is not common.
I have a lot of tools,all kind of screwdrivers,but here I am with no suitable tool for this. No problem. I make one !
Step 2: Materials
You will need :
1. One regular flat head screwdriver ,that you will turn in spanner slotted screwdriver.
2. Files - I used two small triangular files ,this are really old,over 40 years and still useful.
- If you don't have this,a regular small square file can do the job
Step 3: How It's Made
I made the pilot line with the smaller file,and I started to file-it down. It is slightly off center,but it turned to be a good tool.
When I made some progress I changed the files,using the other for finishing.
It is enough to use just one file if you don't have any other.
The depth is 1.2 mm.
Step 4: Done
It is done. Screwdriver hack mod is finished.
The time taken to do this job: 5 - 10 min.
Difficulty level: easy project.
Now you can make your own special screwdriver,to unscrew this type of screws.
