glueing plexi glass

Methylene Chloride, then re-inforce with silicon.

For that height, use 1/4" at least. I like Weldon 3 or 4 and a thin bead of Weldon 16 afterwards.

Most plastic shops carry it Rob. Maybe your local glass shop might have it if they deal in acrylic products as well.

I prefer using Weldon-4 with a syringe type bottle. For acrylic to pvc joints and problem spots Weldon-40 mixed and applied with a small plastic squeeze bottle or large syringe without the needle works.

If it doesnt have to look pretty I would use weldon 40... its a bunch thicker and fills in larger gaps better.however... if you spend the time to sand and fit all the pieces together weld on 4 will make a less obvious joint and a nicer looking end product

what prices have you paid for weldon? i want to make sure im not paying too much locally when i find the stuff.

I second Methylene Chloride. I built my DIY overflow and refugium out of it, with 1/4" acrylic. You just have to make sure the pieces are perfectly FLUSH. The solvent wicks into the crack and bonds them.

if you cuts are good and the fit is tight then use weldon 3 (Methylene Chloride) or weldon 4 which is just a tiny bit thicker than 3 but not noticable. if you have very small voids you can use weldon 16 as it is quite thick but it isn't as strong as Methylene Chloride. The trick is to make sure your edges are absolutly smooth, strait and square in order to get a good joint. Also you shouldn't need any corner reinforcement but it won't hurt.
