The right side roller was more challenging. It's mostly because the aluminum angle at the
aft end of the side rail wasn't welded on quite right, so it makes that latch sit a bit too
far aft.
I decided to sand a shim down that would tip the top of the canopy latch roller aft and the
bottom of the roller forward. Tod do so, I riveted a little angle to the piece I was sanding
so that it didn't get sucked down into the gap between the table and the sanding disc. Note,
I've prevously sanded the end of this block to the correct angle so that I end up with a
tapered shim over the mounting length.
Here's the piece of (now tapered) material from which I will cut a shim. You can see that
it goes from full material thickness (.040) to zero thickness over the length of the mounting
surface of the roller bracket.
So, since the bracket will now be sitting at a slight angle, I made another shim to go between
the roller bracket and the nut so the bolt isn't in bending when the nut is tightened.
Not perfect, but much better engagement with the latch.
However, another problem is that the slot is positioned slightly too far forward. Here, I'm
extending the slot by 1/8".
All done.
Last thing for today...I sanded down and polished the welds on the sides of the brackets.
I'm going to be using some delrin guides to guide the canopy when it closes, and therefore
want a nice smooth surface where these guides will interface.
