macgyver of wood work part 2 .....the failure

in the previous entry i reminisced on how i had  macgyvered my self an encasing for the master of what  would later be a well used mould , alas counting on my implied mediocre effort to complete this task when i went back to the plastics and resin area to actually make the mould , i was informed by the magnificent and ever helpful keith the technician that the box around the master for the mould was sub-standard ( my words not his) and wouldn't survive the liquified gel flex.... so back to the drawing board to create another box , his time with a thicker and sturdier wood so that i can get some screws in to it , as if you try that with 6mm MDF usually it just breaks...that and its edges need to be at least 12mm from whats being moulded , which wasn't the case in the box's first incarnation.
