Foam was first ripped down square with a band saw. Then I transferred the reference marking on to the foam.
Using either a carpenters square or here i just used a piece of left over poster board that has a square 90 degree angle to transfer those lines onto the other side
I then mount the poster board templates using removable mounting spray
Using those reference lines mount the other side in the same manner.
I then use a screw driver and a large drill bit to make an hole threw the center of my ducts, to feed the hot wire into prior to turning the power on.
I then begin my cut by moving to tool up then around the template. And back down before turning the power off.
. I'm very happy with the results. Smooth cuts equals smooth duct work, This shoot was taken before sanding.
I then glue the section onto the other previously glued sections using those same reference marks to make sure everything stays square.
Using my favorite sanding tool, 1 finger, piece of 400 Grit, and the same mounting adhesive, I sand any ridges down on the section i just glued a long fingers helps to reach that 2" ridge. Just remember to leave your back template on while sanding.T
Smoother then most injected molded foam air frames. Without going into building plugs,waxing, glassing the duct work.
