Step 2Drill some holes
iImage Information

Now you want to take a tape measure, and mark off six inch increments from the end of the smaller pipe. I suggest making six marks. Make sure they are measured properly because you'll be using these marks to know where to drill. You can make the marks closer together if you like, but six inches seemed like a good distance to me. Don't make any marks on the last two feet of the pipe because you will not be drilling any holes there. You're going to want to choose your drill bit based on the size of the screws you have. You want the screw to be able to be removed easily from the hole.
