Question about forge liners

Forge builders-
I am making a gas forge which I am lining with Kaowool. Lining the inside with the Kaowool should not be a problem since the inside is arched and I anticipate that the Kaowool will be self-supporting. I'm just not sure how to line the doors. I would like to use three layers of the Kaowool on the doors, but I don't know how to secure the Kaowool to the vertical surfaces of the doors. Anyone have any suggestions?

forge liners

Rob, I have also set about making a forge, and I have had the same question. I have seen posted suggestions using a rigidizer for the Kaowool. The idea being that you can dip the layers of kaowool in the rigidizer and slap them on the door. I am open to alternate ideas.

I was stumped when I read

I was stumped when I read this question. So I did a little web search. Couldn't find much but here's the link to a web site that talks a lot about forge design and building. The author says that he just pushes the installation in place and it stays.

Thanks for all your efforts

Thanks for all your efforts Gerald! Much appreciated. It is not really clear what holds the Kaowool onto the door (mentioned on Ron's website). I was hoping that I could sort of cement the wool in place somehow, but I'm not sure how well that would work in the long .run

Rob, If your door is a 3"

Rob,

If your door is a 3" deep metal pan (5-sided box), the standard way is to do an accordian fold with the Kaowool and stuff it in there with the "corrugations" running vertically. If the door is subject to a lot of slamming or banging, then you'll want to jam a couple or three 1/8" or 3/16" stainless steel welding rods through the door sides and the Kaowool so that they punch through all the folds and keep them from popping out.

If your door is curved or spherical, then you can hold the Kaowool in with SS wires through the door. Or use Plistix or ITC-100 or other refractory plaster to rigidize it and "glue" it in place. Mechanical fastenings are really the best however, due to expansion and contraction with heating cycles.

Rich- Many thanks for the

Rich-
Many thanks for the suggestions! I can picture how this will work. Great! I also spoke with Larry Zoller. He was very nice and quite helpful. He had some similar suggestions.
Thanks again, Rich!

If you used fiber board,

If you used fiber board, maybe you could sheet rock screw from the outside.

I'm playing with building a gas forge myself. I made a crude prototype and am still using it two years later. Need to set aside the time. right after everything else :-)

Rob any chance you could

Rob any chance you could post some pics of how you are putting the forge together?
I have never worked with Kaowool and would like to see the results.

I have an old mankel that needs a liner job bad...

Jim- This will be my first

Jim-
This will be my first time working with this material as well. I will post some pictures as soon as I get to the point of something worth photographing.

Special Waterglass

This product is advertised as "an exellent adhesive for attaching Kaowool,Cerakelt, or other ceramic fiber to metal or other surfaces" Might be worth a try
