are you just pressing pure kief or is it a mix. the kief in your b4 pic looks like its been cured or somthing.
great job you done mate , if you need more pressure that mould would fit in a nice 12 ton hydrolic press . also making smaller plates to go on top of the press plate so they look like a pyramid helps spread the load quite well , slightly heating the mould gives a really nice finish to the block to , you only want it warm though ,
top notch looking press mate , kudos to you
