Let's sort all those parts before continuing.
The thing is, the instructions are not as clear as they could be. I really needed a few read through's and a bit of reflection before I finally understood all of it. But that may be just me being a bit simple...
On the parts, their quality and the fact that everything was present, only one little problem: one "clamp" marked "R" (for "rear") was missing, but was replaced with a perfectly similar "F" (for, you guessed it, "front") piece.
All acrylic parts are perfectly cut, no problems there. Just the protective film... Hate it!
These are the wing holders. A little problem here: I'll need to add some washers between the parts, as the screw is a tad too long (three times out of eight) and the nut won't tighten the pieces together.
Actually, for acrylics (or "plexiglas" as we call it here), I use MEK as glue. It acts a bit like TETC on kit plastic, slightly melting it and so effectively welding the pieces together.
But it's some very nasty stuff: Irritant, highly flammable and... carcinogenic! I use it very sparingly and only in a well ventilated room.
Ahhh! Whatta mistake to make! See the two slight lines between the butterfly nut and the vertical brace? That's where the high vertical part should have been. Only saw the difference AFTER gluing and believe me, once MEK has taken hold, there's no way to separate the parts without breaking them. I'll manage, the problem isn't very big.
