Or, you can cast your own version of a round kiln shelf, with the exhaust opening built in :D

This is what I was thinking about and use the same cast o lite.  Let see what happens with the cast first.

I don't mean to look for used Kaowool, ask about pieces trimmed of Kaowool from working on furnaces. Sure a lot can be used in other furnaces but it doesn't meet code here. I don't know about Ecuador but some pieces are just too small to be useful, it's a practical matter.  Seeing as you did it the easy way and just bought a roll the suggestion is just for the information, maybe someone else can use it. 

If you do it soon enough cast refractory can be cut, sometimes easily. That can be a little risky if you don't let it set up enough. Masonry grinders, cut off blades, etc. work just fine. I have a couple masonry hack saw and hole saw blades.

Actually yes, I misunderstood.  I have not bought the roll yet.  Will call a couple of friends and ask just in case.  Appreciate your help.  Looking forward to try making a decent job with the cast.

If you do end up with remnants to small to be rolled around the casting and inserted, remember that they can just as easily be stuffed between the cast cylinder and the forge shell.

Here the cast!!.  Actually it came out better than I thought for a first timer B)

The molds are still reusable.

If I have to do it again would try to use some type of funnel to pour the cast, as it was not easy.  First I calculated the volume and add about 10% more, then got the weight.  As per the instructions measured 2.75 oz of water /pound and got ready to use 3oz just in case.  After mixing with 2.75  and then 3.00 oz realized it was way to hard to pour it in that shape, so I add a little bit more and got it better.  Guess I was l lucky the amount of mix was just enough to complete it.  Next time will put 15% more instead of 10%.

I used car wax on the outside and the burner tube as release agent but did not put nothing in the inside.  To my surprise it came out very easy, being opened on one side.

I am planing to cast a small flat portion at the bottom to use it as a kiln,  but I am not sure if it is a good idea.  Suggestions??

Just leave it on a flat surface with some was paper plastic wrap, etc., and use the cylinder for a form, to fill its bottom with a refractory disc.

Yes this is the idea, I guess the should bond together. 

What makes me think and have to decide is the size and position in reference to the burner hole.

Ideally, you would cast a disk the same diameter of the  outside of the cylinder. Just let it sit outside the cylinder, trapped in place by the insulation; this way you don't change the position of the burner hole, which looks ideal at present.

Life has been very busy these past months, very little shop time, some delay but project keeps going.

It now needs to be fired.  There is no loose  Kaowool except for the burner port.  I do not want to have loose fibers of ceramic blanket so I need to rigidize and plaster  it with the same Kastolite. It should work ok.

I also need to think on some type of doors for the openings.
