Here's mine. It's too short and too skinny (3") and has a coupla 90's,
but it works fine.
Coupla things to try before stacking up pipe - I don't know if you're already doing this, but if it smokes when you first light it, make sure the stovepipe's warmed up before you light the fire. Burn a piece or two of newspaper right under where the pipe comes into the fire box, then light the fire. The warm air trying to get up the pipe is fighting with a big slug of cold air trying to come down, helps to give the warm air a little boost. Mine smoked me out a coupla times before I remembered this from our woodstove when I was a kid.
If it just does it when you open the door, be sure to open the draft control all the way for a minute to clear the smoke out of the firebox, then open the door.
I like the short pipe, I made a metal clip that snaps onto the rain gutter and to travel you just pull it out, raise it up to clear the clip, pop a 3" cap in the hole and put the window up and off you go. Holds up well, the wind was 24 mph gusting to 34 the other night all night long and no problem.
Looked at your album, I like that storm door idea. Haven't seen anyone do that before.
