I'd like to cut an overflow into the side of a 75 gallon glass tank, like theses pictures I took from the net:
Then I would install an external overflow box. I have drilled holes for bulkheads in glass tanks before, so that is no problem, but this seems much more delicate. It seems people who do this use a diamond rotozip bit and a dremel tool. I have also read that all the edges should be rounded or stress points will be created and the panel will be likely to crack after holding water for a while. Thus one needs to make a wooden guide for the dremel tool. Have any of you done this sort of thing before? If you were successful, could you give me any advice and would you be willing to come help me do it in exchange for friendship and beer? Do you think I am better off just having a small internal overflow box with some round holes drilled to drain the water to an external box? Any opinions would be appreciated.
Thanks,
Gabe
