I have a couple of question for the reverse flow builders. I have been seeing a few builders not fully welding the reverse flow plate, just tack welding it. Is that a good idea? My builder fully welded all 3 sides of the plate to the box. Secondly, how long should the plate be in relation to the smoke chamber? I see some builder leave a smaller opening (less than a foot from the end of the tank) and others that have the plate stop 2/3 of the way down. Is there a correct way to measure the distance it should be? Thanks in advance.
