I think this is the only diy bender that has a wiper die. Usually only see those on the big commercial rigs. Too bad you can't get enough pressure on the pulling clamp so you don't need the nut though your nut fix is impressive itself. Excellent work.

Love the work. I've casted Aluminum, but have never played with bronze, if you were not using scrap but 99% pure metal powder and melting in a vacuum would you go with an aluminum bronze or a 4-5 % tin bronze used in springs and turbine blades? I think it's called alpha bronze where solid tin meets with liquid copper but there is some black magic involved with the mixing that I never grasped.

brilliant using the balls to keep the outside crushing away grease may help them last longer also making them out of aluminum bronzes will make them last even longer.

Put some grease at the square tube that holds the round tube. That way it slides without making that noise. Great DIY

i was pulling too much pressure to the slider die in this clip. less slider die pressure eliminates the fricktion sound sound comes from brass mandrell inside the tube

Does that pressure die move forward simply by friction against the main bending die?

tube is pulling pressure die. it was tightened too much in this video. when its in right tension sound goes away and it runs smooth

main die is steel and made By using radius cutting tool in lathe. long follower die is steel and machined in lathe using linebore bar in chuck and part was in tool post. wiper die is bronze casted in to die and hand fitted. mandrel is bronze. made By using ball turning tool in lathe.

I would like to know what is the radius/diameter of your bending tool. Is there an equation like R_tool = x*OD_tube ? where x is a number or something. Or is there a table. And what is the difference for steel and aluminum? Thank you.
