drilling old tank

[A.PROPHECY]

drilling old tank can it be donr or will the glass crack

also how do i do it lol

[Barrie]

extreamly hard to do as you need to put quite a bit of presure on the glass in order for the drill to go through

What size of hole are you looking at?

If it was small enough, you can buy a spade drill but again, the drill site needs to have a water bath to stop dust and keep the glass cool.

If you need further advice, contact me and I can possibly help( Im a glass merchant)

To make just one hole you can use a piece of copper tube and valve grinding paste. It takes a while but works really well with a lot lower risk than using a glass drill.

You need to make a mandrill for the copper tube (and find a copper tube the correct size). A battery drill will do the job as long as you can hold it straight and square to the glass surface. You water down the grinding paste so it's quite thin and regularly add more paste. You're effectively sanding your way through the glass...

It's a bit of an act to get the hole started but once under way it get very easy. How stable you keep the drill dictates how accurate and straight the hole is.

You will need water soluble grinding paste. I had to ring around a bit to find some. Most of it is oil based and will not work as well.

lol sounds like it will be easyer and safer for me to just get a new tank built with an overflow lol
