[metal] how to shorten the quill?

[mattkime]

I have this guy, and as i feared, he's a bit too long. http://store.velo-orange.com/index.php/c...clamp.html



Unfortunately common stems are too short for my needs so I'd like to cut this guy. My plan was to carefully draw the diagonal line, score it with the dremel, and then hack saw it. Maybe smooth the edges with the dremel. Oh, I'm working with aluminum.

What do you think? Am I getting myself into trouble?
