Introduction: A Car Key Made From a Ratcheting Wrench
A classy car should have a classy and unique car key. I took a 12mm ratchet spanner and tried to replicate the form of the original car key. With only a few basic tools like an angle grinder, rotary tool and few metal files I successfully managed this quite precise job to came true.
How I did it - you can check by looking DIY video or you can follow up instructions below.
For this project you will need:
12mm ratcheting spanner / wrench
Angle grinder with cutting and grinding discs
Vise and clamps
A rotary tool with cutting discs, sanding drum & engraving bits
Small metal files
Metal polishing and buffing pads with polishing compound
Permanent marker, ruler, and sharp scraper for marking
A bit of patient and precise work:)
Step 1: Modifying 12mm Ratchet Spanner
Cut ratcheting wrench to needed length. After that flattened to needed thickness with grinding disc.
Step 2: More Shaping
Used caliper to mark proper width and with rotary tool + drum sander bit shaped to needed witdht.
Step 3: Replicating Original Key Pathern
Covered flattened surface with black marker and scraped original key outer shape by using the key as a template.
Step 4: A Bit More of Copy/paste
When the outer shape was more or less done, I moved to the pair of grooves on the flat surface. Measured and marked with the caliper on a black surface. After that used a rotary tool to cut 1mm dept grooves.
Step 5: Finetuning to Perfectness
With a rotary tool and engraving bit finetuned every single groove and bump to perfect match.
Step 6: Finishing Till Perfect Shine
Sanded with scotch Brite pad on a palm sander. Later on, finished by polishing with two different metal polishing compounds and buffing discs.
Step 7: Final Result and a Test Run
The result was mind-blowing - shiny, unique and what is most important - it turned the car!
