Raymond Walley was an expert modelmaker, and exponent of the Resistance Soldering Unit (RSU). In this programme Raymond explains how an RSU works, describes and shows the associated items needed to get the best out of an RSU, and he demonstrates the techniques for achieving perfect ‘minimal clean up’ joints. He also shows the RSU at work during part of the build of his Broad Gauge Rover.

This programme is a must for anybody contemplating the purchase/use of an RSU, and will demystify the process. He also advises sources of the various items needed.
