All
I have a source for some free ceramic flu liners 7 X 7 inch, and want to know if this will work or not for the heat riser. I have not seen anyone using these, and was wondering why? they seem like another option to a 1/4" steal pipe.

thanks for the a reply in advance

I too am wondering the same thing. Also could they be used for the tunnel and feed tube?

it will work for the heat riser but not for the burn tunnel. the burn tunnel needs a bit of roughness to mix properly. this is a primary reason the all steel welded jobbies dont work so well.

I am not the ex-spert here but 7 x 7 I beleive would work on a smaller sized rocket! On the few I have played with my burn tunnel works best just under a 2/3rds ration. Meaning I would "try" my burn tunnel around 3.5" high around 4" wide? with that sized flue. it's a little smaller than standards that I have seen. you will have to insilate around the out side if you use ceramic in my under standing. Make it with what you got I always say!
