Hi, Go to yotube, look up videos on your brinkman smoker. A lot of great mods. I totally tricked mine out.
The best mods. I put in weber vents in, got them on line. I have 2 extra if you need them.
I use a wood stove rope liner around the top to fill in the gap , it seals well. I have also used aluminum foil
I drilled holes in the wood pan and put a grate in the bottem to get better air flow, A must !
I also drilled holes in the top and side to slide in my temp guage so I dont need to open the top.
I made handles out of u bolts to put on the 2 grilling grates
I put aluminum foil over the water bowl, less mess to deal with.
last but not least I mounted the legs on the out side, I set my wood pan a some 1 inch paving block
when I add wood I just lift the smoker right off and add wood and set it back back over the fire.
Good luck , Tom from Maine
Where can you find the Weber/whoever vents online for purchase?
