Well, I'll grant that it wasn't easy<BR> - but, where there's a will, there's a way - and so, I figured out a way. What doesn't work:<BR> Aquarium silicone, glue gun, super glue, silly putty and caulking. What DOES work?<BR> Determination mostly - more specifically: melting the pieces together for strength and sealing<BR> the seams with <I>Funtack</I>. I melted the lexan sections together with a soldering iron and then<BR> filled in the gaps by lining the inside seams with <I>Funtack</I> which is a product designed to stick<BR> posters on a wall withouy leaving a sticky residue. On a side note, the silly putty worked for<BR> a while - until stuff started growing in it and quickly stared to disintegrate.<br><img src=angle.jpg>", "");
