Anybody install an in-pipe damper with a Leyden

I am new to this forum and new to this Leyden wood stove. I am also new to secondary burn chambers. I am not new to burning wood though. I might be trying to do something that this stove can't do. I have had a fire in this stove maybe 8-10 nights so far this fall. It seems to get the stove to burn with the internal damper closed in the secondary chamber, I need to have a really hot fire. This puts out way too much heat for these 40 degree nights. If I leave the bypass open it burns out too fast. I was wondering if a damper in the pipe above the stove would be a way to find a happy medium until the nights get cold enough to really let this stove run.

I can already tell the cast iron heats differently than the steel stove we had previous to our failed attempt with a pellet stove!

I don't really think I have an overdraft problem. What I am trying to achieve is just a small fire with low to medium heat. I was thinking if I put the damper in, and left the bypass open it might burn like my old steel stove did and just kinda mull along, with just a couple sticks at a time, without being too hot or too dirty. Then when the nights get colder and we need the heat I would just leave the pipe damper open and run the stove the way its meant to be run, hot bed of coals and the bypass closed.

Thats exactly what I am talking about. Maybe I'll try it and post the results of how it works. This time of year its nice to kindle a little fire in the evening and put enough wood in before bed to last four or five hours. I'll be out less than ten bucks to try it.

Yeah I have. I just can't seem to get it where I want. Im thinking if there is a damper in the pipe, I can leave the air inlet open further and it might burn a little better? Maybe, maybe not. Draft is draft I guess. Same result no matter how you control it.

Same thing here. With the air control closed there isn't enough air, but with just the slightest crack its too much. Thats what got me thinking about the damper. I figured someone might have tried it. If I remember the harmon oakwood is set up just about the same as this leyden. I'm sure I will be happy with this stove, just want to find what makes it happy.
