Reposition the lid bale to the back so the lid lifts up from the front and pushes straight back just like a Ranch Kettle lid does. When the lid is in the open position, it will be sitting in the back between the two tables - just like the original One touch Platinum lid did.
You might have to cut the back corners out of each of the those side tables to give the lid enough clearance to swing back in place. Also, you may have to add a handle to the front, down low to allow you to lift, raise, and push the lid back.
Personally, I think Weber ought to mount the 26 on a four wheel cart just like the current Performer Silver model and have a swing up/fold down table in front of it. I wonder if there is anyway to alter a Performer Silver cart to accept a 26 kettle?
