If you are like me and have a bunch of unused old keys somewhere in your home this trick could come in handy.
Today i was going to copy a key with my dremel like tool so i put 2 keys in the vice.
It was a real pain in the vice ;) to get them to align properly, and I trimmed to much of the copied key down.
So i aligned the keys(the original on the a bit larger similar type of a key) on the table, took a spray paint , and sprayed from the 90° angle on them.
So you need:
1.A blank key or a bit larger but similar key with the same profile type.
2.Spray paint. (You will remove it from the original while it`s still fresh.)
3.Any fine grinding tool and a vice/vise.
Step 1: Painting
Paint over the aligned keys (original key up) at an 90°angle.
Clean the original key, and put the copy in the vice.There`s no need for waiting on the paint to dry off.
Step 2: Grinding
Grind the colored part down.
