Ok, so I came up with my mod after checking out the stickys. So far after about 4 hours burn, I am only getting a couple of pellet spill through. in this case it's not over the top but in the 1/2 circle indent below the agitator bar. I suppose one could tighten up the clearance...but you don't want to get that close to the bar either. I didn't do the welding so it cost me about $53 bucks. But hear it is...1/8 x 1 inch weld/steel
