chris im drilling a hole for a 1 1/2in bulkhead on the back of my tank. im emptiyng as much water i can out of it.

drain the tank to just below the drilling point. you'll need to pump/spray water over the area that you are drilling. Very easy, I did this on a 180 reef tank, the thick glass of the 90 gallon is very forgiving glass. Have fun!

thanx for the tip superedge. where did you get your bit from? did you ever here of putting ice cubes in the bit then putting the bit against the glass then drilling?

I just recently heard of this, but I would not rely just on an ice cube for cooling AND lubrication. got my bits from http://www.richontools.com/catalog/c89_p1.html

I drill tanks, I would never attempt to drill a tank that has anything in it... one puts stress on your glass and 2 the MOST IMPRTANT PART!.... when you come threw you are putting glass fragment and dust into your water that your precious corals and fish are living in.

as for the Ice cube part, if you drain your tank properly and empty it. Then when you order you diamond tipped coreing bit, get some proper glass coolent/lubercant and make yourself a dame out of putty, and you are ready.

i have heard of using one of those toilet rings to drill a tank. put the ring down and press and then fill with water and start drilling.

Why not fully tape the inside of the tank where you are drilling. This will catch any dist, and keep the glass from falling in the tank. Then blow air/vacuum from the outside, wash it out. When all clean, remove the tape.

Sure there is some risk, but, IMO, I am sure it would be fine.

Thats two contradicting statements in one sentence.
I would rather empty the tank and then drill it.

Look, I'm a rookie at this stuff, but I am *cringing* at the thought of anyone doing this...

i drilled my tank on its side i wouldnt ever do it standing up..thats asking for trouble..espicially if you crack it...water will be EVERYwhere.... plus drilling my 55 took about 10-15mins each hole.....depending on the hole...going slow....

cliffs: i wouldnt do it
