edge before adding plaster filler stuff.
Finished the burn tube part of the mould tonight, that means the actual mould design is finished! Just need to touch stuff up, make sure that hopefully I can take this thing apart when the mould sets, make sure it will hold still while the concrete sets and doesnt lift up anywhere or anything. So 8 days so far, not quite a week, but meh its basically ready to pour now.
yada yada yada
I sealed the internal parts together with silicon that was laying around, which hopefully will be easy enough to break apart once the mould has set, but strong enough to hold for any shocks or whatever when I pour the mould.
