When soldering the outside throatplate stays it was apparent that there was dirt in the top left stay countersink as the silversolder refused to go in. Having already completed the rest of the stays, Stuart simply stopped & after a spell in the pickle there was no problem when the stay was done again. Where possible resoldering was done during a heat for the next stage of soldering rather than heating for just one job.

After pickling no.1 boiler and a reheat the top left stay is satisfactory
