Back on track and getting ready to cast the plinth. Put the M6 threaded inserts in place for securing the tonearm. I used the threaded connectors that are for joining lengths of threaded bar or studding. Dropped in a couple of Aluminium tubes as tunnels for the cabling. I made use of all the redundant screw bosses, I used a large washer and screw to create lots of Mushroom head anchor points for the casting to latch on to.
