[QUOTE="Tathradj, post: 572747, member: 2436"] A piece of paper then wrap it around the bottle over lapping. Line up the straight edge of the paper overlap then using a suitable sharpie pen, Draw a line around the bottle. Second one is a jig made out of 3 x 4 timber set at a right angle. Drill a hole centered taking into consideration the amount of material removed when cutting. stick a pencil or similar in the hole then rotate the cylinder. Use a thin cut off wheel on a grinder. Don't take a large bite with the grinder. You will be fine. That is the method I use. Mild soapy warm water and rinse the day lights out of the bottle before cutting. I also use the exhaust trick if not sure. Have not been caught yet and do not plan on it. :poop: :bomb: [/QUOTE]
