Firebox question

I have a 20” Horizon offset smoker. My question is about the firebox. Should I be using this grate to build my fire on top of? Or should I remove the grate and build the fire on the bottom of the firebox? What are the pros and cons?

Keep it. It's there to promote airflow around the wood. Nice hockey rink
Exactly. You will find both schools of thought on this. With the rounded firebox and splits, you can shovel out ash from underneath the wood if you go with no grate. However, I agree that more air will flow in a firebox of this size when using the grate.

This should be an interesting discussion.

You need a gap from the bottom of the fire to the bottom of the firebox both for fuel air and the ability to remove ash on a long cook. You also need a damper in the upper firebox to control airflow of the hot air through the cook chamber.

I had a cheap offset. To me that grate is worse than the original grate in my cheapo.
I made a fuel basket that held a lot of splits and charcoal. It spaced heat away from the bottom and the sides of the firebox .
Ignore the angle irons. I had a brainstorm to make an upper shield to direct more heat into the cook chamber. Tossed cheapo before completing the concept

Not sure what happened. I'll try again

I don't have a photo of it inside the firebox or the added air vent
