Default Blanik L13 Windscreen Replacement

Also, does
anyone with experience with this particular job have tips or tricks?
There are about 80 srews around the frame. That's alot of drilling. I
know we need special bits.

Be vary careful transferring your holes (sucks to do something
perfectly wrong...)

Buy the special acrylic bits. They have a special point that doesn't
allow itself to screw into the plastic faster than the tip is shaving
away the base of the hole, keeping it from punching through before the
hole is there (important, otherwise it WILL crack)

Drill at a lower speed and let the bit do the work.

Let the bit do the work. (seriously, don't push it along)

Take your time.

Good Luck! (it gets more tense with each hole...)
