I have a glass cutter..........?

[dmward99]

Hello all I have been reading your site for a while ( will be joining soon :D )and was wondering if anyone out there had a glass drill to drill holes into tanks?My dad gave me what he said was a glass drill bit to drill holes in my tank but I have no clue as how to do this.If someone could drill a few holes into my tank and has the drill they are welcome to use the bits to do some drilling of their own tanks.Since I am not sure if this is a glass drill bit I can snap some pics of the bits for anyone interested and you tell me which way we can go with this.Email me at dmward99@yahoo.com

Hey thanks for the reply Gary,I was wondering if you think the 1 inch hole(which will be my overflow from my main tank to my sump) would be enough to handle my 4-3/4" return lines?I was looking for a 2" overflow hole or very close to it.What do you think?

The amount and sizes of your returns may have no relation to your return requirements. My question would be what type of pump and/or flow do you expect or want on your return? In general a 1" overflow can accomodate 600gph, 1 1/2" 900gph and 2" can handle up to 1200gph. So... if you were looking for someting like 900 gph, you might want to shot for two 1" bulkheads. To be safe, say if one got blocked, 1 1/2" might be a good idea. Overdoing it a little to be ahead of potential flooding is a good thing to take into account. The flow rates are best estimates that can decreased by disturbances and irregularities in the plumbing... 45's, 90's and so forth.

I think I like the sound of a 1.5" size hole for the 900GPH flow rate.Thanks both of you for your help.Although if I am not able to get that size hole drilled I may take the 1" hole offer.

Keep in mind the flow rates are based on the inner diameter of the bulkhead, not the hole in the glass.

 

Depending on the bulkhead manufacturer, you may need a 3" hole in the glass for a 1.5" inner diameter bulkhead. Confirm your bulkhead sizes before drilling

Great thread on RC about glass drilling.......
