I am trying to make my first part an intake and could use a little help. I need 2 one for a 19" and another for a 21" rubber mount Dellorto
1) Steel or aluminum
2) 1" or 3/4"
3) Bending --> I bent 1" aluminum with a standard EMT bender and the radius is huge. Also, it bowed the radius in the bend I would like to keep it round. Advice on how to get tighter bends would be great
