I love PVC pipe and tubing. You can build awesome projects with it like Trebuchets, Steady cam systems, Light stands, Green houses, and tons more. Its a grownups (and kids) big erector set. But some things are too big to glue together so you want to disassemble them. Problem is sometimes your project just wont stay together without some glue. Using PVC glue is messy and smelly.
Now some have asked why I did not just buy some metal spring pins or clevis pins. There are a few reasons. Metal on plastic tends to wear down the plastic and make sloppy joints. The metal spring pins are too tough to push into a tight fitting hole and hard to drill to add a key ring. Plus you can make hundreds of these for pennies where as hardware can end up costing you a lot more money.
Here is my quick, easy, cheap and light solution to this problem:
(the next steps show you what I show you in the video below)
Step 1: First gather your supplies
You will need:
Key rings, you can get 50 for a couple bucks at a stationary store
1/4" poly tubing. You can get 25' of this at a hardware store for less than 5 bucks
1/16" drill bit
3/32" drill bit
Utility or hobby knife
