Oh what shall we say about the lowly Pipe Bender. The all purpose pipe bender is a pipe dream. I don't know why anyone would want to dream about pipes anyway. But what we have here is a matter of using a round pipe versus a square or rectangular tubing. The terminology can be confusing. For instance, when is it a pipe and when is it considered tubing? To make it worse the term " tubing" can be applied to both round and square or rectangular cross sections. You may ask which is stronger? Some engineers say that a square tubing is just a pipe that has collapsed on four sides. So why even bring pipe into the equation? Why not just use all square and rectangular tubing so you don't need to bend any pipe? The answer is the same as always for us simple men. It is a challenge. It is a challenge to take a foe stronger than yourself and show who is superior. Or maybe it just looks better to have smooth cuves as opposed to obtuse intersections. At any rate bending pipe is a skill well worth mastering. But as I said at the beginning, there is no such thing as an all purpose pipe bender. That is unless you want to spend a lot of money. We want to have enough money to buy the other items we may need so here is an example of a very basic pipe bender capable of doing the few bends required in this project. It is available from Northern Tool and is a 12 ton hudraulic pipe bender. It has a bending die for 1/2", 3/4" 1", 1 1/4", 1 1/2" and 2" pipe. It sells for about $130.00. I have this model.
