More commonly called R/F plate or reverse flow plate. Thinner metal works fine on cookers in the 16" to 18" diameter because the heat required to run them is minimal. When you rise into 20" and up the heat required to fuel them is more intense and the firebox box side of the R/F plate takes a beating. I have seen 3/16" plate turn into a roller coaster near the firebox on a 250 build. Between the heat and area to support it cant take it.cclark wrote:yes mdesmond that is the baffle plate....everyone here seems to think you need at least a 1/4" there. At first i was going to try and save some money and go thinner, but after listening to everyone, I am going to go 1/4"
Thank You TQ, it was a fun build.TuscaloosaQ wrote:Kam i just saw that thread on your build for son in law it was jam up wish I had found it a long time ago
