Before I drilled the hinges to final size for the bushings, I wanted to make sure the weldment was in the exactly right position.
\nI trimmed the sides of the canopy skin, to match the fuselage side perfectly.
\nHere’s the right side marked for trimming. It only needed a tiny trim to fit perfectly.

The canopy still matched great, so I\u00a0removed the canopy weldment, and used the lock pin and bushing to mark the wanted bushing location.

First I drilled it to 8mm (5\/16″)

Then to 9mm.

At last I reamed it to final size.

…and installed the bushing. Did the same to the other side, then refitted the canopy weldment and rechecked position and gaps.
\nIt hadn’t moved at all, so I’m very pleased. \ud83d\ude42

My buddy Bo already welded the WD-725 side weldment, so I could continue with laying out the rivet pattern iaw. the plans.

Before drilling pilot holes, I checked the position of the center holes, which will hold bolts for the canopy lock hook.
\nThe line on the channel, marks the center of the lock hole, and the line on the weldment is from the plans. As you can see it doesn’t line up.
\nI will recheck everything tomorrow with fresh eyes.
