What do you think of engraving the header covers?
This was my first attempt at engraving anything.
Actually it was more like skrimshaw. I used a little micro jack hammer that was designed for removing very small fossles from the rock matrix in which they were found. I am not sure if I will put them back on, so I had little to lose. If it works this well on chrome it ought to be a snap cutting aluminium.
By the way the headers don't have enough iron to hold my kitchen magnet, so I don't think rust will be a problem.
