How I drilled my 20gal tank, fully setup with fish already in it.

Please note I have created a copy of the old thread due to not being able to edit the old one and inserting the pictures back into it. The old thread is here http://archive.reefcentral.com/forum...hreadid=234382 please ask all questions if they haven't been answered in this one since it does have teh pictures and the other one doesn't.

Materials required are:
Dremmel of some brand
2 dremmel bits #7134 and #7103
paper towel or tissues
scotch tape
a spray bottle with the pump handles like some bathroom cleaning stuff comes with(but buy one that is clean don't use an empty cleaning bottle)
sharpie marker
and the bulkhead you are using (I used a 1" bulkhead)

Additional notes:
You might have to buy a new collet for your dremmel to fit the small shaft of the drill pieces but I just wrapped scotch tape around the end of it till it was tight in the dremmel tool.


How I did it:

I first got everything I'd need together in one spot.



Take the gasket from the bulkhead and trace the inside circle onto the glass. then take the round tipped bit and start in the middle and move the dremmel around like you are making a tiny circle, this will help incase the dremmel bend. If you bend the dremmel since the hole is bigger then the bit you won't crack the glass.



Keep going till you go all the way through making sure you spay water on the bit with the spray bottle.



Once the hole has been made switch to the tapered dremmel bit. Start in the hole and work upwards pushing and pulling the dremmel in and out of the hole moving it about 1/4 an inch in each direction but make sure you spay it with water. After getting to the top of the circle you made with the sharpie use the marker as a guide and cut through the marker with the drill bit. Make sure you tape some tissue or paper towel to catch the water that is running down the side of the tank from cooling the bit down.



Keep working your way around the tank.



When you get to the top be careful and don't push as hard, do it slowly and just apply as little pressure as possible and it will pop out.



Bulkhead installed





And my fish tank finished.
