But if the sand simply squeezes out the end of the pipe during bending, then it fails at its purpose. I believe you'd have to close the ends of the pipe to keep the sand in place.<br /><br />The purpose of heating the sand (not to the melting point of the PVC please!) is to ensureRobert Salnickhttps://www.blogger.com/profile/17236481906016930762noreply@blogger.comtag:blogger.com,1999:blog-2729582016304811211.post-22633770077197515842016-07-13T22:22:25.949-07:002016-07-13T22:22:25.949-07:00The simplest method that I've seen described i...The simplest method that I've seen described involves filling the PVC pipe with sand. Some people are advocating heating the sand. That seems like a bad idea to me -- if the sand is hot enough to melt the pipe, it will also fuse with it. The better idea seems to fill the pipe with unheated sand, using it only to add internal reinforcement against pinches/collapse, and apply external heat Yodahttps://www.blogger.com/profile/11955078083178330883noreply@blogger.comtag:blogger.com,1999:blog-2729582016304811211.post-30533558710888676872016-07-13T07:18:22.521-07:002016-07-13T07:18:22.521-07:00Yoda -

I didn't show the details of the sink fittings that the tubing fits into: a seal is made to the outside of the tubing. You can get an inkling in the first picture.<br /><br />Also, you'd want to do a decent job of bending the pipe - I think you'd have to heat it uniformly (in a oven?) and then cool it in Robert Salnickhttps://www.blogger.com/profile/17236481906016930762noreply@blogger.comtag:blogger.com,1999:blog-2729582016304811211.post-70030539287787700472016-07-13T00:28:07.203-07:002016-07-13T00:28:07.203-07:00Undoubtedly a clever fix. While reading that blog...Undoubtedly a clever fix. While reading that blog post, I wondered about someone other than a metalworking expert replicating the results. Then I began thinking about PVC/CPVC pipe, and if appearance is a concern, then some silver spray paint as well. While it does offend the "Stainless Gods", it agrees with the KISS and practical DIY principles, etc.Yodahttps://www.blogger.com/profile/11955078083178330883noreply@blogger.com
