Our ancestors were not idiots.
There is a reason why things were done even though we might not see it.

Fun to speculate!

I'm stumped!
The square holes are different sizes, this throws me off.
It does seem that we in the so modern era often underestimate to intelligence of our ancestors.

Those are very similar to the early 1800’s ones with a gap in them, except the gappy ones clearly melted edges. Those look filed. Originally Posted by sharptonn

Very interesting conversation.
I never thought that my post about a razor would spark such interest in wedges.
This is cool.

I’m imagining an assembly process in which several wedge blanks were stacked and clamped on a rod (using the rectangular hole to align and hold them in place) and then filed to shape all at one time. Each final wedge would be finished after the wedge had been peened into place between the scales. Plausible? Originally Posted by 32t

These are definitely punched-in from one side....

Today my mind kept wandering back to these holes......
https://www.globalcastingmagazine.co...nkage-defects/
While reading the link I read this.
"Heavy shrink-prone areas can be chilled in a number of ways. Figure 5 shows holes drilled into the cores and the subsequent cooling pins cast during mold filling. These iron pins serve as radiators to transfer heat from the casting into the sand more rapidly, to avoid shrinkage in those areas. In some cases, pins or fins can be added to a pattern."
Of course in the article they are not talking about wedge casting.
