But why bother with the half round and V shapes at all. What are they for in todays shop?
I guess they used to be used with corresponding top tools. How many of us are swaging 1-1/2" bars
down to 1"? Most of the top and bottom tool work in my shop is done by several 'guillotine' type, anvil
mounted, top and bottom tools.
The Saltfork blocks referenced earlier here look like decent blocks for a fair price but their main
usefulness (to me) would be the bowl, spoon and shovel depressions.
If necessary half round swages can be improvised with pieces of pipe.
