Its useful if you ever need to post a paper across a room...
its simple and really cheap...

I also take NO responsibility for the information i am about to show...
It is for information, and entertainment purposes ONLY

Step 1 Cut your tube

Okay, cut the top and bottom off the tube just before the mounting brackets so you are left with a 2 foot piece of tube. And then file off any rough bits, inside and out of the tube.
