its just a 3x5 rectangle hole in the door blowing under the fire.i had a striaght tube on it,but it didnt seem to help.

Did you ever figure out any of the other things?  I remember you were on a couple weeks ago and
Couldn't get any heat out of it.

If your fire burns better with the door open it's not getting
Enough air in the right place to give you a good burn.

Pictures of your setup may help you get some good advice from the experienced fellows on this forum.  I hope you get it figured out, that must be frustrating.

SSR FIRST WELCOME  to the sight  the way it sounds is the desigh is like a shaver  my stove is blowing sparkes out the stack to i have a 145cfm fan , but what i found out is shaver has only a 75 cfm fan although like there stove the blower is on the back  so it sounds as if your stove is blowing straight in and up the stack , mine blows to the front of the stove so the air has to come all the way back then back up the stack , do you have a flapper over the blower opening as to shut it down when not running    ,, at the worst like  i  thought if mine did not work out  you could could cut the stack off to all most in side top then weld a plate from the back comming to the front this would bee like a would master stove

i think your chimney is to long and your air under the grates is your problem.1st air under grates is probably meeting cloged ash and cant get to coals.i would also try to make a nozzle like manifold for air that blows 4 to 5 '' above grates where the coal bed is.the chimney being that long is sucking out the heat .shortning chimney in firebox will make it worst as heat will flow up and out to fast. your chimney being 14'' in firebox is ok but could be longer.with that much cfm from fan .

the chimy  is just like shaver and dose work but i think the air comming from the front going to the back then straight up the stack what i said about cutting the stack and adding another plat would be just like woodmaster stove

[Scott7m]

The air needs to be Under the fire for the most efficient burn...

If your grates are plugged rake it around a little, but IF that were the case the air couldn't get to the chimney to roar out anyway. 

You really need to get us some pictures on here so we can be of more help, sounds like this project has been trouble from the start, maybe with pics we can be more help

[beeman]

this is what i was thinking dont you just love pict even if they are bad

[beeman]

this is the though

[ssr]

this is the fan mount on the front door

[ssr]

here is door opening and fire box.

funny i can build a 6 second twin turbo malibu shaped like a box,but i cant get a fire blazing in my boiler.aint life strange

Is there grate directly under the chimney? If so put a plate over it. The air is probably blowing straight under the wood and right up the chimney.
To test it you could just let it fill with ashes in the back and keep it packed all the way up to the grate at least 16" from the back.

Most boilers that blow the air under the grate have the fan at the back so it is blowing past the chimney not directly up it.

What do you guys think based on the pics?  Does anyone see anything tharpt jumps out at them? 

In regards to a tall chimey, there are members here with like15-20ft chimneys and they make em work fine, only thing I've ever saw a tall chimney hurt was make a small air leak a bigger problem

If your air is blowing in under the grates that's good, I assume you stir it around some so it dont get plugged up, that could cause that if it was totally clogged in the front and only open directly under the chimney...   

Natures comfort has the drop chimey like yours that I'm familiar with.  There air enters directly under the chimney and is allows to come up through only 3 slots, it works.  So I dont know

Your firebox material looks really thick but you said it's only 1/4". 

As far as the fire getting hotter when u open the door does tell us it needs air and that your air is going to the wrong place, I'd check to see if your grates are clogged

[Scott7m]

Yup, I think rsi is right, the plate of steel would be the fastest thing to try
