Before marking the canopy latch hook bolt positions, I made sure to align the side weldments, so that the skin will line up with the fuselage upper skin. At the bottom…
\n\"Canopy<\/a><\/p>\n

…and the top.
\n\"Canopy<\/a><\/p>\n

I also made sure that canopy glas recess lined up perfectly.
\n\"Canopy<\/a><\/p>\n

Then I adjusted the pilot hole positions, so the latch will be centered in the latch hole.

Next was the side weldment forward ends.
\n\"Canopy<\/a><\/p>\n

I marked and drilled the holes in the attach brackets. Note that one hole is left undrilled on both. There will be skin rivet that would be too close, if I drilled those after plans.
\n\"Canopy<\/a><\/p>\n

I then matchdrilled the brackets to\u00a0the sides..
\n\"Canopy<\/a><\/p>\n

..then fitted them back in place.
\n\"Canopy<\/a><\/p>\n

Before match drilling them to the forward weldment, I reinstalled the canopy skin to make sure everything was still lining up.
\n\"Canopy<\/a><\/p>\n

After checking,\u00a0I drilled the sides to the forward weldment.
\n\"Canopy<\/a><\/p>\n

Now I could remove the canopy frame as one assy.
\n\"Canopy<\/a><\/p>\n

Tapered shims is required between the brackets and the forward weldment.
\n\"Canopy<\/a><\/p>\n

I used a piece of alu angle, to fabricate the shims.
\n\"Canopy<\/a><\/p>\n

Took a while to file down, but I got there eventually.
\n\"Canopy<\/a><\/p>\n

Cut them to length and width…
\n\"Canopy<\/a><\/p>\n

Fits nicely!

The side weldments needs to be shaped in the forward ends, to match the canopy shape. I still haven’t unpacked the canopy, so I’m guessing the shape for now, and will be fine tuning it later.
\n\"Canopy<\/a><\/p>\n

There was a bunch of countersinking to be done on various parts.
\n\"Canopy<\/a><\/p>\n

Also decided to put 2 rivets in the side weldment aft angles.
\n\"Canopy<\/a><\/p>\n

\"Canopy<\/a><\/p>\n

Fast forward\u00a04 hours, everything is deburred and ready for primer.
