I might help the hot spot but it could change the temps on that end a little more than 5*.....if you can place a plate in there temporarily you could tune it a bit before setting it in stone.
Actually, no. A shadow plate is typically located a few inches below the baffle plate. The idea is it deflects some of the direct heat. Putting it above the baffle plate just acts as a heat sink. It will work for a while while it heats up but is then just adds more mass to radiate heat.
By heavy,I was referring to flat plate around 0.25 inch or so.
Well my 13 x 18 shawdow plate made it to senstive when looking it set to low and blocked to much throat gonna try a different way maybe 4" pices and turn them once i get them up in the top or pull them in from the top
So to small of throat will make it difficult to control .
You betcha it will. Too small or too big on any of your openings can wreak havoc on temperature control. It's all based off of volume so you need to be pretty close to the recommended size.
