Melting stick

The business end

The melting stick is constructed using a 220-240 volt cartridge heater. These are readily available from on-line auction sites and other outlets. The heaters are available in 110v and 230v versions and are offered in a range of Wattages from 150W to 600W.

The unit described here is based on a 300W unit, a size which has proved satisfactory for melting volumes of 20 litres and greater. The design of the "tosser tube" is sufficiently compact to fit through screw top lids of plastic cubies and 20 litre tins.

How to assemble

Firstly solder the piece of steel to one of the flat surfaces of a compression nut,this needs to end up at the bottom and is a stand off to keep the heater away from the container walls,tighten the heater into a straight connector using the nut with the stand off then attach the copper pipe,this needs to be short enough that the heater wires protrude. Attach the other connector to the other end of the copper pipe. Put an insert into one end of the plastic pipe and feed the cable down the pipe,connect and insulate the heater to the cable then join the plastic pipe to the connector.
