Cutting Acrylic?

[babcock]

Anyone know the painless way to cut acrylic? I need to cut about a one inch trough out of a divider in my tank. It is at the top of the tank at water level. Would like to cut it without draining my tank. I would have to drain off almost half of the tank to make the water level drop at this spot. Any advice??

Please help
Thanks

Table saw and a good blade...

The divider is mounted in the tank so a table saw is not an option.

router with aq flush trim bit would be the best option if possible otherwise it'll be a hack job. probably better off draining the tank.

I have seen 2-3 foot drill bits (telephone companies use them to drill lines from 2nd floor to first floor to run lines). Perhaps you could attach a circular bit to the end of one of those?

You have sparked an idea. What about a hole saw? If I can get the drill bit started directly in the divider it should plow right through and make a nice trough? Would you gents agree?

That's what we use to cut bulk head holes. Make sure that it's a bimetal holesaw bit and low speed...
