Seems very unlikely since it is so expensive but it's worth a shot. How much do you need marve? Last time I priced it I was shocked. The stove I had was a 6" so I bought 6" and 8" pipe and used screws as spacers. It was a heck of a job involving a LOT of swearing and took quite a while but it met code... of course, it was in a camp and I wouldn't recommend it in a home.

BTW, if anyone does what I did and, use regular screws and a drill. If you use self-tapping screws, grind the bit after you start the screw.... or be REALLY careful.
