From my experience low rpm fans dont do well..

The small high rpm ones work well, your getting plenty of air, building pressure, it's just going where it needs to be.. 

Why I'm not sure yet

Something I just thought of that isn't likely the problem, are you sure the blower has a 115v motor on it? If it is 230v it will turn way too slow.

I'm thinking that if he has embers flying out of the chimney, it has plenty of positive air pressure in the box, maybe too much?

But opening the door makes it burn hotter which means it isn't getting enough air. That is what makes me think it is blowing the air right past the fire and up the stack.

Is the grate removable? If blocking under the grate doesn't help I would try taking it right out and see how that works.

like i said before i put a reostat on the fan motor so i could slow it down or speed it up.that is kinda nice to have but if i slow it down, it does build even less heat

Maybe some pictures of your setup would give a little more insite to what the problem is.

have you tried cleaning the box out and starting from scratch, if you do and it rips it will prove that the air under the grate is meeting resistance with the ash,and finding  a out somewhere besides the wood coal area.how many fires have you roughly burned so far?
