Linn, a maker and the proprietor of the YouTube Channel Darbin Orvar provides amazing tips and tricks on how to work on a varying number of projects from electronics to woodworking, using step-by-step videos made in her shop.
In one video Linn recently posted, she shows us how to bend PVC pipe easily using only heated sand and a little duct tape. This video was a second place award winner for the Instructables 2017 PVC Contest.
In order to heat the pipe without kinking, she’ll need to add sand to the inside of the pipe. This fills the pipe and provides resistance so that the pipe does not kink. She places duct tape over the end of the pipe to block the sand from leaking out. She then measures the amount of sand needed for the particular pipe segment she wants to bend.
This sand is put into a (sacrificial) pan and heated on a burner until hot, then put back into the pipe. After a short period of time, the pipe heats up and Linn then bends the pipe using a shaping jig she created. The shaping jig allows her to get the curve she needs.
This method can be a bit more challenging for larger diameter pipe, such as 1-1/4” and up, but is still a great solution for smaller diameter pipe such as 1/2” and 3/4”.
