Again I am using the pneumatic cutting wheel. This
time I am cutting the pipe nipple that will hold the burner tube in
the side of the furnace. The cut is a 8" radius pipe notch.
Here is the tank with the corresponding hole for the tube. It is cut
on an angle that is tangential to what will be the 8" inside
diameter of the furnace.
Here is a picture that otherwise shows very little. I
am just surprised that I got anything at all. In this picture I am
welding the burner tube in place.
