Well, I first found out about bump keys from an article that had nothing to show what one looked like except for a couple of rough line drawings and the basic descriptions of what they are. So, being the curious guy that I am, and having an old Kwikset key in my pocket, I decided to try my hand at making one. Here's the picture:

After making they key, I found this board. As you can probably see, the peaks are a bit too high, the cuts are probably not deep enough, and may be a bit too wide.

Just thought I'd share.

It is a good try for your first key, but if I were you I would Look at examples on this bored. The key is still a good first attempt.

Yup, It's not too great. Didn't have a triangular file in the shop when I made it, nor did I really have any idea of what one is supposed to look like. I'm going to go get a couple of key blanks this afternoon, as well as a triangular file, and see what I can come up with tonight at work.

Yep, you should make the valleys more deeper and wider to make these bump-keys work more efficiently. Working with triangular file will make these keys more productive. Well, all good luck for your future try.
