brick in door it may have already been said, but here is my spill.... i was able to place fire brick in the door of my shaver 165. i laid 4 on their sides and 2 vertically on top of each other to fill the cavity. the top bricks had to be cut/grinded to fit, which is fairly simple. to get the brick into the door cavity i cut the two top brackets (i was able to leave the bottom ones intact) that hold the heat shield in place. after they were cut i simply pried the shield open (1/2") and slid the brick in. the spacing was perfect for the cavity/brick and after a few quick tack welds is was good to go. there was no need to place any supports under the brick on the bottom portion of the door. additionally the hinges are holding every thing just fine. i felt that this was quicker for me than the concrete board and i have a 2" thick fire brick that will never neeed replacing. like others i added an additional layer of R13 all the way around the unit as well as the digital thermostat and blower modfication. i will try to get a few pictures up in the near future. any thought or concerns are WELCOMED?????
