Brief Description: Oil Heater 22 Heater Outlet Duct Part 1
The top of the heat exchanger needs a place for the now hot air to exit. Time to make another duct.
I used the blue foam again as its pretty good to carve. Pic 2 is my sculpture in place. Pic 3 and it is now covered in two plys of BID after I again microed the foam in another cure cycle.
