Hi all, John here!
Just about to start my first build with the gym ball cast.
I bought a few bits last year to have a go and then ended up having no time to complete it.
Looking to cast over the gym ball with a mixture of -
High alumina cement
Perlite
Silica sand
Fire clay
SS needles
I bought most of these bits last year, I've read a fair bit over the last week....lots of different ideas on a castable refractory formula. Lots just using Portland home-brew type mixes.
I'd really like to use up the cement and needles at the least. Does anyone see any problems with my recipe?
?
Hopefully I can cast a couple of inches and then insulate over the top.
Any help would be much appreciated.
Cheers John.
