Yes, I cut a piece of sheet metal, sandwiched 2 strips of metal top and bottom to channel the draft door, riveted them to the drum, then drilled vent holes through the sheet metal and drum at the same time. Then I inserted the draft door.
The vent holes are 3/4" ea and I left a little space there for a 4th hole just in case 3 were not enough.
The drum will chug along at 250F for hours with only a partial opening of just one vent hole as shown in the previous photo. You would open all three vent holes only during start up to bring drum up to operating temp or if you need to do high temp cooks.
Hope this helps
