I bought a larger 2.5 inch bit here. They are pricey but you could be the future resource for club drilling. Most people take the tank to Cappuccino Bay and pay maybe $30 [?] a hole. I have also seen comments about using a dremel and Harbor Freight diamond bits- cheap but takes all afternoon. Be aware that no one guarantees against glass cracking! Oh, and just as a head's up, you have to use the diamond bit in a little pond of water, so that pane of glass has to be turned up flat/horizontal.[/QUOTE]
thanks for the info...I will be making a border out of clay to hold the water.
