I was checking out my stove and wondering if there's any reason why I can't make replacement secondary tubes myself? I believe they are stainless, right?

the diameter of the holes, spacing and angle of the holes must be correct or the unit will likley not burn as it should. i'd be hesitant to do it unless i had the means to do it exactly to manufacturer's specs
 
Thanks Mike, that's the info I was looking for, just wasn't sure if they were that specific.
 
call me crazy, but I'd do it. Matching up hole placement and size shouldn't be too tough. If you have a chop saw and a drill press it seems very doable. My question would be which alloy and wall thicknesses would be acceptable. If I ever need to replace tubes I'll probably give it a shot.
 
While reviewing specifications on various insert options I noticed that on some units the size and pitch of the holes varied per burn tube.

do secondary tubes wear out? Do th holes erode?
 
I would try almost anything, unless the mfr provides the needed part at a very reasonable price.

My stove is 18 years old, has a channel iron-like secondary air inlet at the top with the drilled holes, and below that is a 4" x 1/4" steel bar which superheats to aid in secondary combustion and keep the high heat away from the secondary air inlet itself. When the steel bar first burned out, I tried to get a replacement from the mfr, thinking it was something special. No mfr response. So now about every 2-5 years I simply buy steel stock, cut it to fit, and replace it. I use stainless screws to attach it to the channel iron secondary air inlet. Been doing this for 10 years. Stove works great.
