So, I continued on the canopy aft channels this weekend. First I spend a couple of hours making them nice and straight, and adjusting the flanges to the correct angles. I used the roll bar template table I built earlier on…

After that, I dug out the F-704 splice plate, that connects the two channel halves.
\n\"Canopy<\/a><\/p>\n

The channels have tooling holes, so I marked these onto the splice plate, to make sure to have enough edge distance when laying out the rivet pattern.

…and good thing I did, the outboard center ones would have been two close to these tooling holes.
\nI chose to make 4 rivets in these rows instead of 3, problem solved. \ud83d\ude42

I aligned\u00a0the splice with the channels, and drilled only 4 of the holes in each channel for now, and only to 3\/32. If adjustments are necessary, it will still be possible when enlarging the holes to final size.
\nUpdate: I made the mistake of fitting the splice plate upside down here, and had to make a new splice plate.. :-\/<\/strong><\/span>

Som spacers are needed, to keep the right distance between the roll bar and the canopy aft channels.

I used double sided tape to hold them in place.
\n\"Canopy<\/a><\/p>\n

Clamped in place.

When trial fitting the WD-725 side weldments, I noticed that the aft angle was keeping the weldment from laying flush with the channels…
\n\"Canopy<\/a><\/p>\n

…so I had to file them flush.
\n\"Canopy<\/a><\/p>\n

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

The right side weldment was still not laying perfectly flush.
\n\"Canopy<\/a><\/p>\n

..so I noticed that Van’s hadn’t aligned it properly when welding. \ud83d\ude41
\n\"Canopy<\/a><\/p>\n

Here you can see how bad it is, compared to the left one…
\n\"Canopy<\/p>\n

I had to cut the vertical weldment, to align it properly. Hopefully I can get Bo to weld this for me too.. \ud83d\ude42

Meanwhile, I am going to drill the canopy hinges again. This time I made drilling bushing from a piece of 1\/4″ cobber tubing
\n\"Canopy<\/a><\/p>\n

Worked perfectly!
\n\"Canopy<\/a><\/p>\n

Then I drilled a 1\/4″ hole in a wodden block, and clamped it to the canopy hinge, using the drill bushing for aligning it perfectly.
\nIt turned out perfectly, but I still have to enlarge it 3\/8″ for the bushings… Ill sleep on it first. \ud83d\ude42
