Drilled Hinges
2/3/05
Having too much time
on my hands one day, I decided to remove some weight by
drilling the rear deck lid hinges. Here are the steps and
the results.
The stock factory deck lid hings were stripped of paint.
The holes were laid out using a fine-tip permanent marker and circle template.
A real machinist would use dykem blue and a scribe.

Closeup shows hole pattern and center marks.
Layout marks were center punched, then drilled with a pilot drill.
The holes were enlarged with a step drill (most holes approx. 1/4", some holes 3/8").
A real machinist would use a mlling machine and metric drills.
All holes drilled, then deburred. The step drill is effective in removing burrs using the next step size.
Deburred, wire brushed, cleaned; ready for finishing.
The hinges were sprayed with a no gloss clear finish..for now
RS-type ducktail supported by drilled hinges and lightweight carbon fiber tube.
