Making Stovepipe Round

brin · Post by **brin** » Mon. Nov. 03, 2008 9:26 pm

Back again........I got a damper for my old caboose stove setup. Problem is this, stove pipe is resting on stove.
about 5 sections plus goes thru the insulated roof jack, all screwed together. No way to dismantle the pipes.
I think I can reach up thru the smoke exit and hold the damper while put the control handle on, BUT the 6" pipe is not round. It is more of a heart shape if you know what I mean, and I don't think the damper will function unless it clears the pipe all around... Anybody know of a way to reform the pipe and make it round like it is supposed to be?
Maybe a tourniquet of rope and brute force twisting might do it? That's what I'm going to try unless someone knows an easier method.
Thanks in advance.

Not sure if I follow you but cant you put the damper up a little higher in a round section of pipe? (there has to be a way of getting the pipes apart....Someone put them together.) Brace them with 2x4's , disconnect a section below the brace, insert the damper & reconnect everything.

Not seeing how to brace round pipes.
I can only see disaster in the making if I attempt to disassemble this towering stack (they were a bear to join together in the first place)
There is no way to lift them off the stove because they are fastened at the roof level and also setting on the stove.

The stacks weight is being supported by the stove?

I hope not nor should it be!

Can you slide the stove to a point where the pipe would come off the stove?

If there are screws in the upper sections of pipe they should hold everything together when you pull the stove away and with the amount of pipe you have it might be able to give (bend without damaging the pipe) enough to get the stove from underneath the pipes.

In any case:

Make a temporary brace out of 2x4's screwed into the stove pipe using the screw holes already in the joints.
Cut the stovepipe with a recpricating saw, below the brace
put the damper in & then reassemble

How do you re assemble where the cut was made? A new section of pipe?

If the pipe is installed, a real big C clamp and some notched 2X4s at the widest point. You will have to go past the point of round slightly as it will have some spring to it. Just go a little and back off, if it isn't enough, squeeze it again. You can do it with your foot if the stovepipe is on the floor.

I solved my problem. I WAS able to raise the chimney enought to unhook sections and moved it to the rear and rested it on a 2x4 cut to the proper length, being careful not to bump it! Installed the damper on the work bench and now can sit back and wait for cooler weather when I will need the heat.
thanks for all the suggestions.

this is a great forum!
