To complete the canopy latch mechanism, I dug out the following parts.
First I marked centre lines and optimal vertical locations for the bolt holes on these blocks.
Then I clamped the latch weldment in place with the blocks installed, to mark the final position of the bolt holes.
The vertical position is determined by the slot in F-705, made about 7 years ago.. time flies! 🙂
The first mark was quite off center, so I had to adjust the hook arm a bit to get the position right.
After getting the position right, I backdrilled through F-705 a few mm, then finished the holes in the drillpress. After that I bolted the whole assembly in place.
Finally I trimmed the control rod to length, tapped 1/4-28″ threads in the ends and installed it.
This is closed position…
…and this is open position.
