New baffle change for Grandma Fisher

I've been beating this around for quite some time so today I did it.
I put Grandmas baffle in a long while ago and it was only 1/4" (it's what I had at the time) It served the stove well and helped emensly with more heat and longer burns.
Over the years the plate warped and it was a royal pain in the a$$ to clean the ash behind it, so I got a idea one day…. I make the plate thicker, longer to slow the burn down even more, and a diverter out of angle to push more heat to the sides and not up to the flue. Will it work???…. It should. I also cut some spiffy corners out so I can knock out the ash from behind the plate…. If all goes well, …. This should increase my heat and use less wood, (in theory)… I still have plenty of space (sq in ) for even flow to the flue so I guess it all will come down to the test this winter…..

 

That piece I put in new is 3/8", I'll get another 20+ years out of that! I have quite a bit of plate lying around now, I almost used a piece of 1/2" but I think the 3/8 will be fine.

 

I almost can't wait to try it out but winter will be on us soon enough.

 

Haven't fired it off yet, but I may this week if it gets as cold as they are saying… I'll keep you posted.

 

Update for all you who either added or considering the baffle, I fired her off last night for the first time this year. "As" I expected I got a little burb back in the house, "not enough heat to cause the draw yet" After my stack temp got up over 200* it started heating like a dream!!! Much more heat going to the surface of the stove and when I opened the doors, it fired heat right in the room!!… It's still early in the experiment but it's looking up!

 

I understood, My thought there was to try and stop as much flame going to the flue as possible "longer burn" My only concern with the angle turned the other way would be a burb in the smoke. As it is, I'm getting a small amount on light off with this configuration. This baffle is longer and has the angle so I think I'm "just" pushing the limits of the air box area, Mathematically it has the correct area but I would'nt go any bigger with this one. After about an hour, the old girl was "cranking" out heat!

 

Ok Guy's, "UPDATE"! As you all know I made this baffle a bit longer and added the angle… Well The pro and cons are on the table now! I've burned a few good fires now and I have been cold iron for a few days and did my usual light offs tonight after work a bit ago. "the cons" I never used to get a "burp" of smoke in the house on initial light off, now I do … I'm going to have to either live with it or trim it back about an inch… "the Pros" "ONCE" its fired and burning, "no problems what so ever" even opening the door to re-load. and most of all it is KICKING A$$ with heat!!! I think for now I'm going to live with the con and figure out a method to at least not get that initial burst of smoke in the room. My thoughts here are it was a 90% success so I'm happy.

 

No, Once mine is up to temp, I don't get any burp because of the heat flow. It's only on initial light off and only until the flue temps get hotter. Once I'm above 200* I don't seem to get it.

 

Are you meaning on my Grandma bear Fisher?
