Duckworks landing light

Hi Guys

I'm about to fit a pair of Duckworks landing lights in the wings of an RV9a, and I would appreciate any tips on drilling the plastic: holes sizes are from 3/32 upwards, and I know you should use the correct drills but they start at 1/8 (so it looks like a standard bit for the 3/32), the holes go up to 5/32, plus some countersinking - advice welcome

Cheers - John

What he said

Take it slow as the drill bit will want to grab the plexi and crack it. I was able to do mine with standard drill bits. Just take your time.

Plexi does not like to be worked cold

P.S. I was also able to do mine with standard bits

block of wood on the back side where the drill bit will exit

This is a very good piece of advice.

I would mention that countersinking this thing for the dimples did not produce a product nearly as nice as countersinking metal. Getting a smooth and unwaivering c-sink was difficult. Take your time and dont look for perfection.

Good point Spike.

I found that by taking my time and simply hand spinning the countersink bit produced a much better countersink than spinning it with a drill. It took a lot longer but it looked much better.
