This post covers the last couple of days.
\nThere’s a bunch of brackets that needs to be fabricated for the roll bar, like these F-632D angles:

They are made from 0.125″ thick extrusion.

…and these F-631C Angles, made from 0.188″ thick extrusion.
\n\"Fuselage<\/a><\/p>\n

Also made two splice plates, F-631E

These two F-632E angles..
\n\"Fuselage<\/a><\/p>\n

..and this F-632D angle. This one doesn’t look like much, but the angle had to be adjusted to 88\u00b0. That took a little effort to get perfect.
\n\"Fuselage<\/a><\/p>\n

To get the assure the proper height and width of the roll bar, I cut a template from some furniture plywood I had stored away.
\n\"Fuselage<\/a><\/p>\n

I added small angles in the corners, to fix the roll bar sections.
\n\"Fuselage<\/a><\/p>\n

I had marked the template centreline, as you can see the sections need trimming.
\n\"Fuselage<\/a><\/p>\n

That’s better!
\n\"Fuselage<\/a><\/p>\n

Both sides of the aft sections trimmed.
\nI didn’t really take any photos of it, but I spent 3-4 hours fine tuning the sections, so they don’t warp\/twists. This was a hell of a job, but I believe the end result of the roll bar\u00a0will be much nicer.
\n\"Fuselage<\/a><\/p>\n

The aft sections needed a 1\u00bd” hole, for access to the installation hardware. Here the centre of the holes a marked.
\n\"Fuselage<\/a><\/p>\n

I used a hole saw in the drill press for these.
\n\"Fuselage<\/a><\/p>\n

Then I match drill the aft splice plate to the sections.

Last thing I did today, was to start preparing the upper and lower straps, that will join the forward and aft sections of the roll bar. They need to have a radius on the edges against the sections, to fit properly.
