Pegasus Posted January 18, 2005 Report Share Posted January 18, 2005 This may be of interest to those contemplating adding a sump. Quote from Chris (one of our members on another site) Hi i found these guys on ebay about a month ago and decided to give there diamond coated drill bits ago considering they were cheap and didnt i have much to lose. Here is there link search.ebay.com.au/_W0QQg...propertyZ1 Since buying them i have drilled 5 sheets of 6mm glass with the 22mm bit and it is still going strong. All you need is a pedistal drill set on about 250 rpm some water and about 10mins . Ive decided to buy another set just to have as spares. Even their delivery was quick. Here is a link to some pics www.geocities.com/hxkings...5478262930 Hope this info is helpfull to anyone else who wants to drill a few tanks.

spinedoc Posted February 11, 2005 Report Share Posted February 11, 2005 I have drilled my sump using patience and a very cheap system. I purchased a standard set of holesaw drills from mitre 10 ($6) and a $7.50 pottle of valve grinding paste from Repco. I selected the size of drill and mounted in my hand held drill (no fancy drill press). To keep things lined up I drilled a hole through a piece of 25mm pine and then clamped it to the glass with another piece on the reverse side. The hole in the wood was lined up on the glass. The tank was positioned on its end so the working surface was on the top. The hole in the wood acted as a well for the grinding paste and keeps the drill lined up. I set the drill to reverse and about 30 mins later I had a very smooth edged hole in the glass. The teeth on the holesaw were ground down about 50% and would easily cut more holes as the metal acts as a medium for the grinding paste to do its work. PM if you want details. I found this much cheaper than purchasing diamond drills for one hole. Different if you were drilling lots of holes. Cheers Quote Link to comment Share on other sites More sharing options...

Joshie Posted August 17, 2005 Report Share Posted August 17, 2005 For $10 odd dollars do they require the tank pulled apart or will they drill with it assembled? Quote Link to comment Share on other sites More sharing options...
