When I received my 590 in June (july?), I did a burn in and then a bacon cook to season it. With the bacon cook, I noted grease dripping out of the bottom of the barrel on back side. After some sleuthing, I found the leak. As you know, the factory caulks all the seams with red RTV, but the rivet holes are not caulked! And what happens is the rivets, do not completely seal the holes. So I caulked them and reported this earlier this year with pics. No outside leaks since then. Also, found that the way the grease got to the bottom, was that the pit was not level and was tilted to the back (due to slope of my porch), then down the grate supports and then down the back side of the barrel to the bottom. So I have since turned the pit to that it is level front to rear, and thus the grease drips mostly down on the drip pan. However, I would like to see the elimination of the leveling problem since grease still will make it to either the front or back grate supports. I have a solution to keep the grease from dripping down to the low side of the grates and thus down the front or back of the grill and of course missing the drip pan. But don't know how to get this done:
Grill grates should be curved down at the center, so that grease naturally runs to the center of the grates before dropping onto the drip pan. This would only require an angle of about 10 degrees or so to accomplish this. Would this be easy to do in a machine shop, or would the grills have to be actually constructed that way? Or am I just too OCD? These are thoughts that can only happen during the cold winter when I don't like to be outside doing more constructive projects. Comments appreciated.
