yeap, i think pulling this out of the sand might be a little hard but if i cant do it normally what ill do is add a little molassis to the sand (its mostly used for bonding cores) then put plenty of parting powder on the pattern and that should hold the sand together better if the wet sand dosnt work alone.
got my cpu block machined today and all ive got to do now is drill out the holes for mounting and for screwing on the top, tap 4 of the holes (probly an M6 thread and is 4 enough ? theres room for more..) and i started lapping it but havnt finished yet, its looking alot better
