More drilling tonight. I’m going slowly, but so far everything is working out nicely.
Match drilling the side rails takes some care. Because the aluminum rail is pressed up against the Perspex, and there are no pilot holes, the Perspex drill bit doesn’t completely exit the Perspex before contacting the aluminum rail. Switching to a regular drill bit and drilling through the aluminum rail requires drilling through the last few millimeters of Perspex with a regular drill bit, which risks a crack on the backside of the Perspex. I don’t expect to find any issues, but I’ll carefully inspect it when I disassemble in a subsequent step.
The wooden structure inside the cockpit is providing great support for drilling the canopy rails.
