Cutting glass questions

[drfu]

Does anyone have great tips on how to make a three sided cut on a glass terrarium. The cut will go down either side from the top of a rimless tank down 6" and then accros 6" to make an opening. This is going to be a turtle basking area attached to the top of another aquarium.

Some notes.
Terrarium is a one piece curved 3 sided piece of glass, rimless, it is not tempered.
Own a Dremel, have a diamond point carving tool for cuts.

Picture with green panters tape is the area i want to cut out. Thanks in advance for any tips/tricks on how to do this since i cant simply score, snap of a piece.

i don't have an answer for you, but curious as to what exactly your plans are? You're making like a walk-way for the turtles to go between two tanks?

Yes, instead of doing the standard in tank floating docks/basking area, i want a separate tank attached to the side where they can go up a ramp, have a separate basking area with some sand substrate, separate heat lamp/uvb bulb and relax.

Safest thing would be to Drehmel the whole thing out (probably take a few bits). You can Drehmel out the vertical sides and then use a glass cutter to connect them--being careful not to run your score line below the drehmelled out sides by even a millimeter. It would be to your advantage to score multiple lines with about an inch between them to give you leverage with flat pliers to snap each subsequent score line. Of course make sure you do all off this scoring with the tank well supported with the working side down.
