I am a student in hvac and AM doing a project with 3/8 copper tubing. I have to take a 10" peice of 3/8 tubing and bend it into a circle using a lever type bender solder it and pressure test it to 110psi. I am having trouble making the circle. Is there any tricks that may help with the bending process to make my circle look more like a circle rather than an egg. This is just my second week as a student . thanks for any info
