500 watt Dummy Load

A friend asked me to make up a heatspreader for a 500W load resistor and fit it and a 7-16 DIN socket to a giant heatsink weighing about 15 lbs

Close up of the 90 x 70 x 12mm spreader
Mounting block for the 7-16 DIN connector and RG401 1/4 inch semi-rigid coax

The load and coax will be soldered to the spreader, and high performance conductive paste will be used between the spreader and the heatsink.
