Best glue for acrylic to glass?

[Beza]

I dunno, I think that in this case there would be an extremely high tendency for shear on a butt-joint held by something like silicone, which allows flex. I was thinking of a solid bond by something like an instant glue, backed up by a big bead of silicone.

The problem is the stupid butt-joint, which is the weakest connection available. The braces that normally are on these work because they are a single molded form, and they hold on 3 different axis. Acrylic has tensile strength with torsion, and the torsion is going to be a weak spot. I might have to go with glass on this one, or use a thicker piece of acrylic with ridges cut into it. Sigh.
