I was wondering if this bump key could be improved or if I could get some tips to make a better one. I made it from a blank key and a dremel tool.
Here are the links to my pix.

looks like valleys one and two could be a bit deeper (one and two are closest to the shoulder). We've also found that the peaks really don't have to be that high to successfully bump a M1 key.

If the key, however, is bumping -- don't change a thing!

What I always do is filing slowly according to the correct procedure and always make valleys deeper and wider. It will be good most of the time and I am learning all the time by practicing more and more.
