G'day fellas, I've just recently bought a pipe bender witht the intent of making some sidesteps. The problem is when I try to bend the pipe I end up with these crappy kinked looking bends, particularly if I try to have any significant kind of bend. I know that if you want a perfect bend you need a mandrel bender. But is this the best I can expect? this picture is two testers i did, and you can see how crap the bottom one is. the top one is ok but I think it is only because it was about 5mm wall and I packed it with sand. I think if I tried to bend it any more it would kink. Can someone help me and give me some hints? I'm stressing thinking I've just wasted my money on this bender when I should have just got it bent up in town.
