Hi Charles , yes I can see what your saying and to get a steady feed from the cross slide I grip the handle with both hands and press them against my body and then turn the handle with a steady rocking action to get a steady controlled feed ?!!!
\cheers for looking in

The condenser end plates have all been drilled and tapped 7BA with no breakages ...!! i use the resistor colour code to quickly identify my drills and tools etc... so...Purple is the colour for 7 and Green is the colour for 5 ... this is quite helpful unless of course one is colour blind ??!!! the next job is to install the condenser tubes these are actually soft soldered in place at both ends , rather than expanded as per steel tubes ...
