I took a break from the canopy latch handle and went back to the latch itself. I trimmed the lower ear as specified in the plans for weight savings. After taking this picture, I used the touch-up paint that matches the powder coat to cover the bare metal.
Next, I drilled the bushing blocks out to full size and temporarily bolted the latch into place.
Finally for this evening, I fabricated the idler and linkage. The upper hole in the idler will connect to a pushrod whose other end is attached to the canopy latch handle. Here’s the mechanism in the latched position.
And here’s the mechanism in the unlatched position.
