Thanks for the kind words Dan. I resisted the urge to do more than a test heat. Up close the stand has lost of little things I wish looked better but lack of free time made me leave well enough alone. My fumed silica was waiting for me today when I got home so I finished the blanket lining and rigidized everything. Hopefully I’ll have time tomorrow to cast the inner shell so it can cure while I’m gone next week. I’m also going to be welding 2” angle iron on the back of the stand to keep my brick door in place.

helo ser did you have any luck turning fumed silica intoo rigidizor, and may i ask what particle size is needed too make coloidal silica, Thanks.
