Edit: the interface where the burn tunnel bricks and the square opening meet the round riser is a point where the metal pipe could be exposed to high heat, I'd make sure that you use bricks cut and fitted so that no metal is exposed to direct heat. Some will cob a few bricks around the riser to hold it in place with friction, so perhaps a layer of fiber blanket cut to shape that the riser sits on would help too?

But for a riser she would need a 10" pipe for her 6" riser.
After reading Matt Walkers site, even 1/2" blanket will work, but the 1" works well for pipe sizing.

Holy crap though....300 feet? That would be enough for 100 RMH's!
As an update to my earlier post, I managed to find a business just across the border that offers a postal service to provide an address for people like me. Should be arriving in a week or so.

I did use hvac 10" on mine but it was the heavy wall trunk line pipe not the super lite transfer pipe.

Creating your own size pipe is sometimes easier and cheaper than buying larger sizes.

After learning earlier this summer about the radical difference between refractory ceramic blanket ( very hazardous) and non refractory ceramic blanket(Morgan superwool plus) not hazardous!
I purchased 12.5' of non hazardous 1" blanket.
Our friend and fellow rocket scientist Eric Hammond had a horrible experience working with the refractory blanket ! He hated it ! Worse than any fiberglass, he thought a full tyvek suit and respirator should be used.
Today I worked with non refractory blanket ! Sweet ! Easy to cut, like working with a nice thick blanket! Single edge razor blade slid thru like butter. If I had known the exact size I needed to cut it really would have taken five minutes to build my five minute riser.
For those wanting to build an 8" riser . I started out cutting a 31" piece , 10" x 3.14 = 31" for the true I.D. With 1" thick material I first cut back to 29" then 28.5" and finally 28" even. I did have a few spots on the seam where I stuffed a thin trim piece in but only from my less than perfectly straight cuts.
I used a stainless tie wire to make sure my stove pipe stays snapped together.
This riser is now ready to install ! How sweet it is !
