finally, the trimming and adjusting of the windscreen has come to an end. The sides now nicely fit the sides of the fuselage.
I added painterstape on the rollbar and positioned the windscreen in place for drilling. Used some duct tape to make sure it stayed where it's supposed to be.
Mesaured the distances for the screws. Actually reduced the spacing a bit and added some more screws than required on the plans.
drilled the first hole.You can see the marks the painter tape makes where it touches the plexi.
Important: make sure you angle the drill correctly so it's perpendicular to the plexi. The touching point is sometimes at an angle. If your holes are not perpendicular, you'll end up with problems later after tapping the hole and trying to insert the screw.
Each time marked the location of the mark.
then used the same technique as with the slider drilling. Put a wooden popsickle stick under the plexi and drill the hole with acrylic drill in the plexi. Then replace the wood by eventual washers and drill with the regular twisted drill through the roll bar.
