Step 3Drilling & sanding

Drilling & sanding
Let's put it together, I used chewing-gum like material to fix it in place.
And drilled about 40 holes. It is better with some vertical-fixed drill for better quality. And take it slow
with plexi-glass, or train few holes on dummy piece.

Even if you did carefully drilled all holes like me, there may be not-matching edges (foto3) after putting together. It will look better if you shape them to one line. First use 180 grid sand paper if you end with big gaps like me. Then use 250 grid. Finally you can play hour or so with number 400. Until it's looking perfect.
