this is a quick instructable

with great results.

Drilling nicely straight holes

Using something tubular ie copper pipe , etc

But try and make sure the rim of the pipe is 3mm roughly

And that the pipe will fit the jaw,s of your drill

Step 1: What You Will Need

you will need

1)a drill

2)pipe cutter or a piece of pipe about 2-3 inches long.

3)sandpaper.

4)clamp or tape

and that,s it

Step 2: Cut the Pipe

with your pipe and cutter.

at about 3 inches or so down the length cut your pipe.

using the pipe cutter

the pic with just the tube is what you should be left with

now place the pipe or tube into your drill

using quite a coarse bit of sandpaper

tape it or clamp it down.

then with your drill at a 40-45 degree angle.

bevel the edge of the pipe using the sandpaper & drill,

while your holding the trigger down slowly move the drill left to right ,because you dont want to be going through the sandpaper.

once you have a nice bevel.

its onto the next step

grab a scrap piece of wood.

and start drilling away.

if the tube skates all over the wood.

go back to the sandpaper and change the angle slightly ,

down and up movements with the drill will get you there.

and there you have a nice straight hole.

thanks for looking,

and remember .
