Got a question. Sounds like a lot of knowledge flowing here. I just bought an old Timberline, but the firebrick in the back and on the sides is broken. It looks like the back and side bricks are about 9" x 13" x 1-1/4". I can't find replacement brick anywhere.....Any ideas?
My father bought 2 of these stoves when I was a kid growing up (and my family still has them). I thought they were great then and still do! Did I get taken for $300?
 
I have an old Timberline myself. My firebrick measures 9"x4.5"x1.25". I think you could fit some new brick into the areas you need it, then trim the remainder to fit. I think the thickness of the brick will be the defining factor, as a tile saw should cut through it without a problem. There are others here with WAY more experience than I, hope they can chime in for you. BTW, I modified mine to secondary-air, w/baffle, and am still playing with ideas. If all goes well, I'll post the results for review. If not, a video of 10lbs. of tannerite going off in a Timberline stove.
 
Dave, I've been looking for bricks recently too. 4.5" wide is the only size I've seen. Best deal = $15 / 6 @ Northern Tool. I don't burn 100-lb loads, so while I'm at it I'm going to reduce the size of my firebox from > 5.5 to < 4.5 cu ft by adding more bricks and stacking flat instead of standing on end. Some think it's a bad idea, but many think it will burn better for smaller loads.
 
Beetle, I'd like to hear any details you'd care to share. I'm thinking of adding a baffle by setting a couple of steel plates atop my thick brick sidewalls. Air could be ducted to the upper firebox with a piece of angle iron placed over 1 of the ~2.5" intakes. I have no idea if this air would be sufficient in amount or warmth to support secondary combustion. I know it wouldn't work as well as a stove designed for secondary burn, but I'd be happy if it would work for a short burst while I tended it. Anyhow, if your stove has excess capacity, you might want to try stacking bricks for a thicker lining goining higher up the walls. Consensus seems to be that this would yield a hotter primary burn and distribute heat to the top of the stove more than the sides. Both of which would seem to be beneficial for supporting secondary combustion. :)
 
Den, I got the idea from "Pen", and "Glfporshe". Type in a search for "fischer secondary air". Pen built up a firebrick baffle that seemed to work well, and Glfporshe did the full mod. I did this also, but am having flue issues right now, so I can't report on the results. My box was 3.0 CF, and now is 3.6 CF, to the bottom of the secondary tubes. You'll need a decent welder, grinder, and a drill press or mill would help, but it's not difficult. Because my capacity is larger now, I'm adding more brick to the sides, under the air-supply tubes. By baffle plate is 1/2" plate steel, with firebrick on top of it. It should stay nice and toasty in there. take a look at what the other guys did, and you'll get some ideas.
 
Thank you one and all for your replies. I guess I'll have to cut and fit the standard size in.

I would like to hear how you make out with your stove. Beetle-kill, I hope the tannerite doesn't have to be put to use. Please include pics. if possible, of your stove revisions or the tannerite.
