With this simple technique, you can heat bend custom fittings in any kind of PVC pipe. The secret to the process is using a controlled heat source and spreading it out. In a word keep: it moving, keep it rotating. (OK, that was more than "a" word) BUT Before getting into this, I have to plug Techshop an awesome resource for the toolhead like me at techshop, I can have access to pertty much any tool I can imagine. I have quite a slection at home, even more at work, but none of my tools compares to what I can have access to at the Techshop www.techshop.ws Step 1: Heating the pipe PVC pipe is created by a process called extrusion.Extruded products are all around you: Spagetti, macaroni, aluminum door thresholds, vinyl window frames, plastic bags even plastic water bottles (which start as extrusions before they are blow molded) all these are extruded. In the case of PVC pipe, chips (or beads) of rigid PVC plastic are heated up to a molten state and forced through a hole correspondng to the shape desired - in this case, a pipe. As the pipe is extruded, it is held in a straight line until it cools into a solid length of pipe. PVC is a thermoplastic - which means that it becomes soft when heat is applied. You can use this little tidbit of knowledge to heat and re-form the pipe to a new shape without compromising its physical properties if you are patient. The best tool for heating the pipe is a heat gun - available for around $25 from your local hardware big box or online (search: 1500 watt dual temperature heat gun). You can also take your piece of pipe into the kitchen and use your stove top - just make sure your wife isn't home. What doesn't work so well is a propane (or MAPP) torch as the heat is too concentrated and charring the PVC is highly likely. Save the torch for making your PVC diggerydoo but that's another instructible. The key to the technique is constant movement - move the PVC pipe or the heat source back and forth over a 12" or so area and keep the pipe rotating all the while. After 3 or 4 minutes, the piece of pipe will start to sag. Keep it moving and rotating and begin bending it while rotating it - all the while keeping the heat on. http://www.instructables.com/id/Bending-PVC-pipe-Just-because-you-can/ Step 2: Finishing the bend Once the PVC pipe is good and soft, lay it down on a flat suface and bend it while rotating (or rolling) it. Do not bend it quickly or stop rotating too soon or the pipe will kink. Once the bend is the correct angle, hold it while it cools. As long as you don't overheat it or kink it, it'll hold pressure just like a straight pipe. Remember: your heat gun is also your friend when running PVC pipe (or conduit) and you have to make that ~12 degree angle in order to get it into that next fitting - even if the pipe is already in the trench. Just remember to keep the heat source moving - but please don't try drying your hair with it Related Instructables How to Bend PVC 002 - Forms (video) by pvcbendit Bend PVC Pipe by Thinkenstein How to Bend PVC 014 - In Depth - Bend Clear PVC Pipe (video) by pvcbendit How to Bend PVC 013 - Bend Clear PVC Pipe (video) by pvcbendit How to Bend PVC 007 Part 2 - Minimum Inside Bend Diameter Continued (video) by pvcbendit How to Bend PVC 001 - The Basics (video) by pvcbendit . http://www.instructables.com/id /Bending-PVC-pipe-Just-because-you-can/ Food Living Outside Play Technology Workshop Bending PVC. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 http://www.instructables.com/id /Bending-PVC-pipe-Just-because-you-can/ Intro: Bending PVC pipe - Just because you can Have you ever. bending it while rotating it - all the while keeping the heat on. http://www.instructables.com/id /Bending-PVC-pipe-Just-because-you-can/ Step 2: Finishing the bend Once the PVC pipe is good and
