Gentles All
There have been various theories concenring the cause of the dent row in "B" type S&L RK's.
Please consider the following:
S&L appears to have approached the production of medals in a progressive fashion, and probably produced most fo the awared RK's (next to Junckers). Junckers relied on traditional methods of cutting out the inside of the RK frame stamping (very time consuming and labour intensive). If you look at Junker RK's and the varying "inside cuts" some are very accurate and some are downright poor resulting in large gaps between frame and core....probably its this "hand made" feature that attracts us subconciously us to Junckers RK's ?
Anyway...if you take S&L there is a uniform feature about the frame....the inside dimensions are the same (across the frame measured from the inside rim) on all my crosses, and this suggests that they used a cutting die to remove the inside of the formed blank. In fact vertical die cutting lines are often evident.
Process: The forming die set produces the frame stamping, and the cutting die removes the inside...
Now, the cutting dies are not detailed..their purpose is to remove the internal excess...can I postulate that the dent row was caused by a raised surface in the female of the cutting die, and not in any way related to the forming die set.
As one who spends a lot of his professional life assessing welding standards, I can assure you that the dent row is not weld splatter. Imagine dripping a little water into a very hot frying pan of oil....the resulting spots that would appear on your kitchen work surface is what splater looks like !...its not a uniform line.
OK...the "A" dies required rework, and the craftsman took great care to fill and rework the cracks that appears in the female half of the forming die and then left a streak of weld only in the valleys of the female die rib patern in the lower 3 o'clock arm, but only removed the welding from the peaks???...nope, no way !
I believe that the forming dies were repaired to a high degree, but that the dent row was introduced later in the process of stamping the frames. ..ergo: a cutting die defect and not one in the formiing dies.
If the dent row was a feature of the forming die (but only on the female) then the tendency would be to creating a thinning and possiible hole in the beading. This is not the case.
So I postulate that there was a raised surface (debris) in the cutting die that actually "dented" the frames during the cutting process.
So what does that give us ????
