we used a hf bender to do a couple things and are using one to build a cage if you are patient it can be done but it wont be totaly as smooth as a true bender but we also didnt have $600 plus to buy a bender.. we were lucky to get tubing you know. i think this has been discused do a search.. some tricks to use a hf bender. take your time be slow. you can sleeve the material with another tube to slow down the kinking and the little dimples that the rollers cause. we also took a old bmx tire and cut it up and wraped the tube and that also helped alot. all in all if i had access to a real bender i would use it. but i didnt , so we used hf one on my buddies rig, hf fabricateing rules..
