[highlight]^^^ Checked on the net, the emblem is nigh-on impossible to make with the files and sander, casting could be the only solution.
Take a photo from the net, cut out a profile in wax, and then detail with small piercing and cutting tools needles, scalpels etc.
Make a female cast over the wax with clay.
Heat the clay to melt the wax and let it drain off.
Melt aluminium and pour it into the clay mold.
That 's the theory, I suppose one would need quite a few tests before you can get anything resemblong the original piece. [/highlight]
