good info. this is farther than we've ever gotten in these how to bend brass tubing threads.
If it's brass, get the trick instrument makers use: fill pipe with soapy water, plug the 2 ends (rubber plug if possible) put pipe in freezer for 36 hours (to make sure all of your water is frozen solid), remove from freezer and bend it: voilà...a perfect bended tube with no kink!
The pipe bender you have should work You need to heat up your brass tubing first. Heat up the entire length you want to bend to red hot and let it cool down on its own, dont quench it, Once its cool then use your bender. Use firm constant presure and let the bender do it's job. Dont just squeeze it like your tighteing a pair of pliers. No need to put anything in the tube. The real trick is having a form to press the tube into. The form has to match the radius of the tubing. Ive made my own jigs from hardwood and rout a 1/4" radius into the jig, In this case you start the tubing at one end and press it into the form till you get to the end of your bend.Hi everyone
I am going crazy trying to get 1/4 inch pipe to bend at a 90 degree angle without it crimping. I have tried a pipe bender, pipe bending springs,filling it with sand, heating it then try to bend it all of the above in one go and all with the same result: kinked bends. How can I get a 90 degree bend without the middle of the bend caving in on itself? I need to essentially make a U bend. It has to be a tube to run the power wires up through the middle
edit: forgot to mention it's brass tube Im trying to bend
If it doesn’t work, can you show a sketch of what you’re trying to make?Well, I am reporting back on the ice method - didn't work. The ice just cracked and got forced out the ends. I am thinking the radius is just too tight for the metal. However, after reading Sawduster's post, I realised I didn't heat it up enough to red hot, so maybe that's where I failed on that attempt, so I'll have a final crack at that. If it fails, then I will have to resort to a solid rod and shrink wrap the wires to the sides which is not preferable and it also means I won't be able to detach it from the base for transport.
