The other way I have seen this done is to fabricate a custom round end mandrel out of wood where the round is cut with a router on a circle jig, and then the correct radius matching the tube OD is cut into the cylindrical face of the mandrel using the router with a bull nose bit. Essentially building a tube bender but with large bend radius.<br><br>Sean<br><br>-------- Original Message --------<br>On Apr. 17, 2020, 18:49, Rick Patton via Personal_Submersibles < personal_submersibles@psubs.org> wrote:<blockquote class="protonmail_quote"><br><p dir="ltr">Well I fabricated a jig on my fab table using 3/16” X 1 1/2” flat bar, packed the 1” SS tube with sand, welded ends on it, said a few prayers and went for it. I first tried cold bending it but needed a much stronger jig for that so I pulled out my rose bud and hot bent it and it worked great! Now I have a lot of buffing to do to make it look pretty again.<br>
