This is how to bend a pipe without a pipe bender.If you want to bend a pipe without kinking it carve a couple wooden plugs for the ends. Pound one plug in and start pouring sand in the other end. Fill the pipe completely and then tap it against the ground to compact the sand. Keep adding sand till you can get no more in. Pound the second plug into the pipe. It will compact the sand even further. Now you can bend the pipe without kinking the walls. I use the receiver hitch on my truck for the bending part. When you are done drill out the plug and dump the sand out.
