Busy building a jig for sand casting my psru housing. Will send
photos after the jig are completed. Going to mix my own green sand
for the casting.Don't know if a have "saddle up a difficult horse "
but goring to try at least. Has got hold of aluminum engine blocks
which are going to be used as casting material.There is a foundry
nearby that can melt the blocks and help with the casting. The
housing will be post cure (heat treated ) after a successful casting
has been made. Then the housing will be machined  to took the
planetary and bearings

   Hi Le Roux,
     I think you will need to put a slight angle of draw on the mold
or you will have great difficulty in removing the plug from the sand
without damaging the sand mold. Chris was able to do his mold in 2
halves I think, but with              that  many stiffening webs you are
not able to do that. the other way is to make the pattern from wax and
get the foundry to do a lost wax casting.
