While discussing the solder marks, let us take a quick look at what is being presented as the solder used to fix the base of "the slender tree" to the base plate. First of all let us note (assuming there was a tree) that the small area of the circle of solder does not mean that the object it attached was so slender. There may have been for example a sawn-off tenon at the base of a thicker element, and it is the stub of the tenon that was soldered to the base plate.
The dimensions of the base plate are nowhere given in the book and it is difficult to judge the diameter of this solder patch. Nowhere are its precise details discussed. The only photo which shows it nearly close-up indicates it is an annular zone of something-grey with an irregular edge and irregular upper surface. And here is the puzzle if we want to interpret this as traces of an attachment of a larger unit. How was this solder applied? If the solder fixed a large object to the plate which was wrenched off, where is the traces of the lower edge of that object preserved in the upper surface of the solder? Where is the trace of tearing of the lead solder 'pad' that would occur as it was detached? Why does the upper surface of the solder look (from the photo) like it has been roughly smeared on with a soldering iron and left? Has anything in fact ever been attached to anything by this solder? Can we have some better photos which show the characteristics of a broken soldered joint if that is what CMA want to claim it is?
Has CMA's Dr Bennett ever done any soldering (but not using a modern electric soldering iron)?
