Fisher Swage Block Pattern

Fisher Swage Block Pattern painted red and black

Fisher Swage Block Pattern:

~12" square

From the famous Fisher-Norris anvil company. A typical wood cope and drag block pattern. The paint colors indicate red for as-cast surfaces and black for core prints. For each core print there would be a core box to make the sand core. While it is not obvious the pattern will have a very slight draft (taper) so that it will pull cleanly from the sand.

A fairly well designed pattern with numerous graduated features. However, the row of half rounds (at bottom above) creates a weak corner at the left. Shifting the whole row about 1/4" to the right would improve the structural integrity.
