[Greetings everyone,
This is James Avery...hehee I'm back into the group. Been out for various reasons.
But, Here's what I know is the best deal with drilling tanks.
1. Always use a tripod or a drill press to drill them unless they are like a 10 gallon...
2. You can use a round pvc pipe about 3 inches high and glue a rubber seal to the bottom.
3. Place the rubber sealed pvc onto the area you want to drill the hole.
4. Put antifreeze in the pvc area...(that's why you want the seal on the bottom of the pvc.)
5. Place your drill bit down and turn it on very slow. You can put a bag of sand or something like that on your press handle so you don't have to hold it. This will way it down and grind the glass to create the hole.
6. Now you have a hole. HAHA!!
Be very carefull when creating holes. Almost all tanks doesn't have the bottom tempered. I really don't know any that do. But you know as soon as I say that, some numbnut will do it. I do know that oceanic tanks are tempered all around except the bottom. I think the oceanview tanks aren't tempered except when you get into the larger ones like 100 gallon...Not positive though. And all DAS tanks aren't tempered or at least the chief there at DAS told me that.
A really good place to see all this happen is
www.wetdryfilter.com Tell him that James Avery sent you if you purchase anything. I don't get anything from it except kudos.
Thanks,
James Avery
Hope to see everyone at the next meeting.]
