bubble alumina

[dtec1]

hey guys i had asked in another thread about this stuff being able to stick to the walls got a good answer from ray how ever i ran into another problem and wanted to see if any one else has had the same problem or any one with some advice. i drew a diagram FIG.1 was what i was planing to do but after all the other layers i went to put in a thin firebrick as the floor to mark out where to put the bubble alumina and now that the chamber has narrowed the brick sits to high. the burner in my forge sits on the side (not up on the top at a tangent as it should) yeh i guess i could move it but that would require alot of work as everything is 1/4 in steel (project for another time) even if i sliced a lil off the sides still to high and they are the hard "split brick" firebrick that are only a lil over a inch thick i think 1 1/4in. the best would be if i could thin them out even more but i dont know how to go about that my ban saw is broke the table saw blade isnt tall enough tried putting on a belt and disk sander and i would be sanding for weeks to thin it out. tried a angle grinder but i dont have masonry grind wheels i tried metal grind wheel didnt do anything (ill try and pick up a masonry one tomorow maybe). the only other thing i could think of is if i turned the brick flat and not on its side so the table saw blade would reach through and cut off little 1/4 in (around) slices and do what is pictured in FIG.2. and embed them into the top of the bubble alumina. however even if i stacked them tightly next to each other there would still be cracks where they meet going down to the bubble alumina and eventuly other coatings and i dont know how long the bubble layer would last with so much flux seeping through the cracks. no point in doing that if it will only last a couple sessions in that case i need a better way. ANY one with any advice on this wether you think "FIG2" would work or not or any other optiopns i havent thought of would be greatly appreciated THANKS
